Kirill: This is episode number 87 with Tableau and Qlik

Intrapreneur Deepak Prasad.

(background music plays)

Welcome to the SuperDataScience podcast. My name is Kirill

Eremenko, data science coach and lifestyle entrepreneur.

And each week we bring you inspiring people and ideas to

help you build your successful career in data science.

Thanks for being here today and now let’s make the complex

simple.

(background music plays)

Welcome to the SuperDataScience podcast, super excited to

have you back here, and today we've got an interesting

guest, Deepak Prasad. Deepak is a Tableau and Qlik expert,

and he works for a company called ASG Group, where he's a

consultant, and he helps other companies to implement

business intelligence in their business. And what business

intelligence basically entails is developing business

intelligence dashboards and tools which can be helpful for

executives, managers, and just generally other people in the

business to see their data and understand how the business

is progressing in various areas, whether it be finance or HR

or perhaps operations, and so on.

So we'll be talking a lot about business operations, and

Deepak will give you some of his insights about Tableau,

Qlik, and Power BI, and we'll touch on a couple of other

tools as well. And of course, he'll give you some tips on his

best practices in business intelligence, so stay tuned for

that. And, finally, Deepak will share parts of his journey and

how he structured his career in this space, and how it

Page 3: SDS PODCAST EPISODE 87 WITH DEEPAK PRASAD · guys would benefit from Qlik,” and then your goal is for these organizations to adopt these products. Is that correct? Deepak: I would

brought him to where he is now. And he'll give you some of

his best tips on how to have a fulfilling career as well.

So I can't wait for you to check this out, and without further

ado, I bring to you Deepak Prasad.

(background music plays)

Hello ladies and gentlemen, welcome back to the

SuperDataScience podcast. Super excited to have you here,

and today we've got an inspiring guest, Deepak Prasad, on

the show. Deepak, welcome. How are you going?

Deepak: Fantastic and really energetic to talk on this podcast.

Kirill: That's good. Where are you calling in from?

Deepak: I am signing in from Sydney.

Kirill: Sydney. Ok, so it was really cool how we were talking before.

You mentioned that you would never live in Melbourne

because what? Why wouldn't you live in Melbourne?

Deepak: Basically, I come from a tropical climate. So anything below

20 is a bit of a pain for me and very tough to accommodate,

so I don't want to take risks in that aspect at least.

Kirill: Yeah, totally get it. Totally get it. And I really want to share

with everybody the chat that we had with Deepak just before

the show started. Deepak, you have a baby boy, right? 2

years old?

Deepak: Yeah, his name is Aryan.

Kirill: What is his name?

Deepak: Aryan – A-R-Y-A-N.

Page 4: SDS PODCAST EPISODE 87 WITH DEEPAK PRASAD · guys would benefit from Qlik,” and then your goal is for these organizations to adopt these products. Is that correct? Deepak: I would

Kirill: Aryan.

Deepak: Yeah, exactly.

Kirill: Wow, that’s so fantastic. Congratulations. It’s always

exciting to hear when people start families. And you were

like — Deepak said to me, “Kirill, there’s one thing that I’d

like to one day find out.” What did you say, Deepak?

Deepak: I really wanted you to get married and I wanted to see you

again after marriage, whether you’re able to tie up with this

podcast and regularly do productive stuff or not. So I just

wanted to put you under an experiment that’s called

marriage.

Kirill: Well, hopefully it won’t be an experiment. It will be, like, one

day for good. But you want to see how my productivity will

drop after marriage, how it will change?

Deepak: No, I really want to see whether it’s going to drop or it’s going

to increase. It’s either way.

Kirill: Yeah, okay. I found that funny. And we both agreed that it’s

a matter of priorities. Once you’re married, there’s just other

things that you care about in life. You know, right now, for

instance, I love travelling. I love doing sports and cool stuff

and just seeing what life has to offer. But once you’re

married, it doesn’t mean that you stop, or you become

boring, or you’re less productive, or whatever. It just means

that there’s other things. Like, you might spend less time on

creating products or courses or something like that, but you

spend more time with your kids and family, and I think

that’s a very, very noble and important and loving and

fulfilling thing to do. How do you feel about that?

Page 5: SDS PODCAST EPISODE 87 WITH DEEPAK PRASAD · guys would benefit from Qlik,” and then your goal is for these organizations to adopt these products. Is that correct? Deepak: I would

Deepak: Very true. Just imagine me after a tiring day at work

returning home, seeing my wife and kid playing and having

fun, and my kid jumps on me and says he missed me and

stuff. That keeps me going. That whole day, whatever

tiredness I had will just vanish as soon as I see my kid

laughing. So things like that will keep you going. Although

you say you cannot do certain things and you cannot plan

and you cannot act as per your plan, but things like

happiness, seeing happiness from your kid and your wife

keeps you going.

Kirill: Yeah, I can totally imagine. I feel the same about my family

and my friends. Yeah, I can totally imagine that. You

definitely need those parts in your life. Otherwise, if you’re

just working all the time, you’re never going to be happy.

You might be successful, but you’re never going to be

fulfilled. I think this is even more important than work.

In fact, I’m actually in the Czech Republic right now, and I

have a friend here, and we just had this conversation today.

Even though he’s not super successful in his career and he

hasn’t made millions of dollars or billions, he’s super happy

because he’s travelled the world, he’s done what he’s

wanted, he’s got a lovely girlfriend, he’s in love and he’s just

living a very fulfilled life. It was very inspiring to see.

Deepak: True, true. You’ll get into the game, man. I wish I could learn

from you.

Kirill: Thanks, man. So, Deepak, tell us a bit about yourself. I’m

looking at your LinkedIn and it says you’re a Tableau and

Qlik intrapreneur. A lot of people have heard the word

‘entrepreneur.’ What does ‘intrapreneur’ mean?

Page 6: SDS PODCAST EPISODE 87 WITH DEEPAK PRASAD · guys would benefit from Qlik,” and then your goal is for these organizations to adopt these products. Is that correct? Deepak: I would

Deepak: Intrapreneur, as the word says, is like promoting some

products and tools across various organizations. So, when it

comes to technology, you will become an expert, and once

you become an expert, you understand its pros and cons.

And once you understand it, you get to expose it to the

people, you get to expose it to the right persons. So that’s my

day in and day out work. I go to people, talk about their

problems and I tell them that this is what will work out after

listening to them. If I straight away go and sell my product

just because I have it, that won’t work.

Kirill: No, it makes total sense. So you’re kind of spreading the

data analytics and data visualization culture within your

organization, is that right?

Deepak: Yeah, exactly. Basically letting the people know the power of

visualization.

Kirill: Okay, that’s really cool. And how is that going? Are you

finding a lot of resistance, or are people generally quite open

to learning about these things that you’re sharing?

Deepak: When we talk about visualization tools, and when we explain

how it works and how it can help, although it’s not the first

thing, people will come and conclude the conversation with

“How much does it cost?” That would be the first question or

the last question. Everyone would finish it. So I always make

sure that the old technology and old processes, what we

listen — and we should not be suggesting some “old process

plus new technology”, as quoted by the HP CEO, I believe.

So it should not be the case that old process plus new

technology is equal to expensive old process.

Page 7: SDS PODCAST EPISODE 87 WITH DEEPAK PRASAD · guys would benefit from Qlik,” and then your goal is for these organizations to adopt these products. Is that correct? Deepak: I would

So I make it as a statement in my everyday work. I should

not suggest something which is just a new technology alone,

I should improvise the process and the behaviour of people

of any organization and then I should show them an insight.

If you just throw a new technology at people, it will not work

out. You should understand their data culture. You should

ask them more questions, and you should ask them what

they’re currently doing and you should really consider them

with a current process and the technology you’re trying to

bring in, is that the value proposition that’s going to be good

or not. That’s the equation you have to arrive.

Kirill: Okay, gotcha. I’m just trying to rethink is. Help me out here.

So, you are a consultant, and you go into other

organizations and then you look at the processes and you

decide that “You guys will benefit from Tableau,” or “You

guys would benefit from Qlik,” and then your goal is for

these organizations to adopt these products. Is that correct?

Deepak: I would say 70% correct. The reason is I wouldn’t just talk

about Qlik and Tableau. Since I’ve been in visualization for

five long years, I know Qlik, Tableau, Power BI and many

other tools. We also evaluate other visualization tools in the

market. For example, I’m keeping an eye on tools like

ThoughtSpot, which is really a disruptive innovation, as I

call it. It is definitely going to turn the industry upside down

one day. So, some tools like this, you have to keep

evaluating and understand the pros and cons.

So when you said Qlik and Tableau, I would say no, those

are not my only verticals. Because I have seen the pinnacle

of Qlik and Tableau, so I call myself a Tableau and Qlik

Page 8: SDS PODCAST EPISODE 87 WITH DEEPAK PRASAD · guys would benefit from Qlik,” and then your goal is for these organizations to adopt these products. Is that correct? Deepak: I would

intrapreneur, but if I feel that Tableau and Qlik will not fit

an organization considering their current process, I would

say that “Qlik and Tableau will not fit. Try something else,”

which means I can suggest these things and these are the

services I can provide you.” So that’s how the dealing should

be.

Kirill: Okay, gotcha. I’m just trying to compare that with what I did

at Deloitte. It’s a bit different because there, we used

Tableau, or some other visualization software at Deloitte,

within the organization, in order to then solve some

challenges or solve a case for our client and then deliver the

results. We didn’t actually go in and say, “You need

Tableau.” We did the work inside and then we just delivered

the results. It might have changed since then, or maybe I

just worked on those types of projects, but that’s my

experience. But for you, it’s a bit different. You not only

deliver the project, you actually want to help the

organization change their processes so that they can further

down the track keep doing this on their own.

Deepak: Yeah, that’s true. The other thing when it comes to business

intelligence, as you know, it’s also called a Decision Support

System, so if something is supporting your decision, it has

to come along with your culture, behaviour and other stuff.

So, for me, data visualization is not just a technology. It

blends people well together, then only you can win. So

anything you produce and no one is there to view your

product, whatever it may be, rocket science for you, but if

the user utilization is 2%, what’s the point in coming up

with a rocket science which no one uses? So when there is a

demand, you should push it and you should create a

Page 9: SDS PODCAST EPISODE 87 WITH DEEPAK PRASAD · guys would benefit from Qlik,” and then your goal is for these organizations to adopt these products. Is that correct? Deepak: I would

demand. The behaviour of the people has to be initiated,

elevated in the right way such as that they adapt to the new

technology and they improvise the process and everything.

Kirill: Okay, sounds like quite an involved process, you would

spend quite a bit of time. On average, how long does it take

for you to complete one of these projects?

Deepak: When it comes to project, I wouldn’t call it as a project. I

would rather put it as a “solution”. So you talk to persons,

you understand what they do day in and day out, and then

you understand what problem they are facing. Once you get

to know their problems, then you get to know what are all

the possible solutions you can come up with. There might be

a scenario where a solution can just be implementing a

product like Qlik or Tableau, or you might be saying that the

way you ingest the data and massage the data itself is

wrong, so we will give you a resilient database and we will

give you a fantastic data mark which consolidates the data

from your whole organization and brings it to a single place

and then we will plug in a visualization tool like Power BI,

Qlik or Tableau, whatever. So it will be an end-to-end

solution. Along with the existing process, we will try this.

Then we will have a discussion with them stating, “Okay,

this is all possible and this is not possible because of a

budget constraint,” or whatever the constraint may be. So

we have to talk like this and we have to do a proper gap

analysis and then come up with one approach which brings

a smile on both our faces.

Kirill: (Laughs) That’s a good way of putting it — one approach. So

you just bring smiles to people’s faces. I think that’s the best

Page 10: SDS PODCAST EPISODE 87 WITH DEEPAK PRASAD · guys would benefit from Qlik,” and then your goal is for these organizations to adopt these products. Is that correct? Deepak: I would

job. It’s like Santa Claus, you’re like Santa Claus of data

science.

Deepak: Yeah, that’s what we are here for. If you just give what they

ask for, smile will not come. If you give them something

more than what they ask for, that’s when the smile comes,

and you see a happy customer, and you’ll also see many

returning customers. When you give something, you should

not just give what they ask. You should give an impact,

that’s what I call it. Impact is what is very important, rather

than just “Give a solution.”

Kirill: That’s true. And what part of your job is education?

Obviously, you need to educate your clients, or your client’s

employees, about how to use this product and how to get the

most benefit out of it and get the correct insights, not the

incorrect ones. So what part would you say is education?

What role does education play in your career?

Deepak: Education is very important when it comes to business

intelligence and data visualization. The reason is, as I

mentioned before, you have come up with some product and

if there is none to use it, no matter what your product does,

it goes for a toss. So, when you do something, people have to

be perfectly educated about what you did and how they can

use it. So when it comes to — I’m a strong believer that

when you design a dashboard, or when you come up with a

product, that product should be following a certain

methodology.

For me, I consider all the users as a king. For example, let’s

talk about a king’s life. If a king wakes up from his bed,

before his feet touch the floor, there will be sandals kept

Page 11: SDS PODCAST EPISODE 87 WITH DEEPAK PRASAD · guys would benefit from Qlik,” and then your goal is for these organizations to adopt these products. Is that correct? Deepak: I would

there. When he walks down to his bathroom, automatically

all the soaps, towels and everything, whatever is going to

work today will be ready and lying there. Just tell me one

thing: Would the king even know who has kept and when

they are kept and why they’re kept. He doesn’t have to worry

about these things. He just has to get into the bathroom,

and he will take his towel.

According to me, the user interface and user experience has

to be like this. For the user, it has to be very natural. You

shouldn’t even realize that these things are all very well-

planned and kept here by someone and that’s when we have

to use it like the soap. It has to be very natural for the

people. That’s why I call it cognitive. So, the natural way of

digesting things. You have to design your products such that

it is very natural for people to use. If you keep your search

bar somewhere in the bottom down, definitely people are not

going to find that at all. The search bar, by default, it has to

be in the right top or somewhere that people focus by

default.

Kirill: Yeah, I totally understand. So where they’re used to seeing

the search bar — on most websites the search bar is at the

top and so on. And at this point we’re slowly venturing into

product design. Before we continue with that, can you

explain a little bit for us? For people who are not really

familiar with business intelligence, what is a product in

business intelligence? What are these things that you deliver

to your end users? What do they look like? How could you

quickly describe them to us so that we can have an image in

our heads what a business intelligence product is?

Page 12: SDS PODCAST EPISODE 87 WITH DEEPAK PRASAD · guys would benefit from Qlik,” and then your goal is for these organizations to adopt these products. Is that correct? Deepak: I would

Deepak: So, as I mentioned earlier in the podcast, business

intelligence according to me is a decision support system.

When you claim that you’re a hero and you don’t have

proper data for it, you are just a person with an opinion. I

strongly believe in that. For your organization, when you get

into a diagnostic mode and see how your business is

performing, and get insights and plan your future, you need

data. So once you have your data, you need a presentation

layer up above what I would call a ‘business intelligence

layer’ where you can ask questions to your data and interact

with your data and come up with your findings to construct

your future.

So that is the layer I’m talking about, that is the layer which

is called business intelligence, which is very important for

each and every organization. So if you just have data lying

around and if your data keeps on growing and if you don’t

ask proper questions in the right time to your data, just

imagine about your organizations. It would be just flat. It

would be just following whatever has been followed, and it

would just keep on doing that. There would not be any

optimizations. There would not be any study of what

happened, what is happening and what is going to happen.

To answer about all these W questions – what, when, where,

why – you need data. So when you have data to ask this

question in a seamless way, you need a business intelligence

layer.

Kirill: Gotcha. So, in a way, a business intelligence product brings

together data of your organization and presents it in an

easy-to-read matter. For instance, in Tableau, that would be

like a Tableau dashboard, in Qlik, it would be Qlik

Page 13: SDS PODCAST EPISODE 87 WITH DEEPAK PRASAD · guys would benefit from Qlik,” and then your goal is for these organizations to adopt these products. Is that correct? Deepak: I would

dashboard or Power BI dashboard… It’s mostly dashboards,

the way I imagine it, and everybody’s seen these. There’s a

pie chart, there’s a bar chart, there’s an area chart at the

bottom. And from that, just by looking at it, you can tell,

“Okay, we’ve sold this many products. Revenue is up, this is

down,” or whatever. Or it could be a segmentation

dashboard for a different department. Is that about correct

in terms of a visual image of what a business intelligence

product looks like?

Deepak: True, very true. When you said, “From various departments

in a single dashboard,” that talks about it. So, when you

have different departments and different data laying around

in various departments and it is not segregated, then you

will not get insight. When all your data is segregated from

various departments and you put it on a dashboard and you

understand the associative relation between each of your

departments, then comes the insight. So that insight to you

can be provided by business intelligence layer is what I’m

saying.

Kirill: It totally makes sense. That’s pretty cool. What we

mentioned, that in different departments you have different

data and different goals. So maybe the finance department

wants to know information on the sales and the revenues

and expenses and so on, whereas the operations department

in a big company that has a call centre, the operations

department wants to have a dashboard on how many calls

are they getting, how many calls did they get this week, how

many calls did they answer, how many calls they didn’t

answer, how many calls were escalated, how many e-mails

they got, they only get information on that, so completely

Page 14: SDS PODCAST EPISODE 87 WITH DEEPAK PRASAD · guys would benefit from Qlik,” and then your goal is for these organizations to adopt these products. Is that correct? Deepak: I would

different purposes. Do you have a favourite? What is your

favourite type of department to work with? Or tell us maybe

about the differences of working with finance, operations or

other departments and the different type of dashboards that

you’ve created throughout your career?

Deepak: For me, HR is really, really interesting data, always, because

I’ve done a lot of things in HR analytics. When it comes to

HR, the way of you seeing the data would be completely

different. What you just described, sales, operations. It’s all

about numbers, right? But when it comes to HR, it’s about

the people. Salary would come from a different department

or whatever department they’re tagged to. And the company

has its own KPI of deriving how people are performing, how

productivity is there.

So, when it comes to KPI in HR – KPI is the key performance

indicator – what I try to say is, when it comes to HR, it is not

about the KPI alone. It’s about people. You have to take

people into the measure. There are many other parameters

that should come into play when it comes to HR department.

That’s the reason I like HR data a lot more. Whatever the

dimensions you see the data, every time you will find some

interesting insight. And those insights differ from various

organizations. Organization A might not be having the same

insight in the same situation as for organization B,

depending upon their HR wireframe and so on. That’s

interesting data, I would say.

Kirill: Okay. That’s really cool. And with your experience in

dashboards, you obviously know some best practices and

how to create these business intelligence products. Can you

Page 15: SDS PODCAST EPISODE 87 WITH DEEPAK PRASAD · guys would benefit from Qlik,” and then your goal is for these organizations to adopt these products. Is that correct? Deepak: I would

share some insights with us, some tips that you can give to

our listeners about what are some tips on creating these

business intelligence products so that they are indeed, as

you said, useful to the people? So maybe how much

information there is, how many maximum charts there

should be on a dashboard, or what colours to use or

anything from your experience that you think is important,

some important guidelines to follow when creating BI

products?

Deepak: Yeah. So, when designing a dashboard, when it comes to

best practices, you have to keep certain things in mind. The

first thing, and very important thing, is increasing the data-

ink ratio. So when it comes to a dashboard, it is very clear

that we are going to put some insights for your data. Other

than data, nothing else should speak in your dashboard.

That’s one primary important thing that I had to highlight.

Let’s say that you come up with a very good insight in a bar

chart and your title is 16 font size. Just tell me whether

people would look for insights in your bar chart or in your

title?

Kirill: In the title because it’s so big.

Deepak: Yeah, definitely. It’s so big. So, you have to be really

concentrating in your dashboard where you want the

people’s focus to be and you have to be carefully drafting it.

And let’s say that you have five or six charts in the same

dashboards and you really feel that you need all the five or

six charts. Situations in this place would definitely ask you

— if I am sitting beside you, I would ask you to revisit again.

If six charts are there, which would be the first one people

Page 16: SDS PODCAST EPISODE 87 WITH DEEPAK PRASAD · guys would benefit from Qlik,” and then your goal is for these organizations to adopt these products. Is that correct? Deepak: I would

would be looking at and whether — when correlating all the

six charts in the same dashboard, you should be making

sure people should not derive some wrong insight that you

don’t want them to. And when you come up with six charts

in the same dashboard, it’s about landscape as well, how

your real estate is going to be maintained and whether

people will be able to focus.

As I told you earlier, the data-ink ratio should be increasing

and the space between each and every object, not just charts

– let’s say title, let’s talk about headers and footers, let’s talk

about logo placement – each and every object in your

dashboard should have at least a .5 centimetre to 1

centimetre gap between each object. I think Tableau 10.4,

the latest version of Tableau, is quite concentrating on this

stuff which is quite exciting. I’m very eager to try that as

well. So they’re going to come up with a concept called

‘spacing between objects.’ If you set 0.75 centimetres as to

spacing, all the objects will be evenly distributed and will

have a white space around that.

Things like that would let the user clearly differentiate

various objects and concentrate. And your logo placement

and colours you choose, that’s very important. When it

comes to visualization, colours are very important. Also, I

know that you have a separate course in Udemy for colours

alone.

Kirill: Yeah, yeah. I personally learned so much from creating that

course. I didn’t realize how colours are important. I mean, I

realized that they’re important, but I didn’t realize how

Page 17: SDS PODCAST EPISODE 87 WITH DEEPAK PRASAD · guys would benefit from Qlik,” and then your goal is for these organizations to adopt these products. Is that correct? Deepak: I would

exciting this theory of colours is. Yeah, you’re right, it’s

really cool.

Deepak: Yeah. And when it comes to colours, you have to make sure

colour blind safe. And when you are very sure that you have

a brand and you wanted to generate a colour palette from

the brand logo, you have certain tools in website like Coolors

– coolors.co – that’s a very good website for you. If you just

upload your picture, it will give you a colour palette to follow

so that your colour palette, whatever you are following in the

dashboard, would almost go with your company standards.

Kirill: Yeah, and there’s a couple of other tools. There’s a Coolor at

Adobe – color.adobe.com – the same thing where you can

upload your image. Yeah, Adobe Coolor, maybe that’s the

same one we’re talking about. But you can find a couple of

those tools online, they’re very useful, I agree. Sorry, you

were going to say the next thing?

Deepak: Yeah, things like this would be — you have to leverage many

things when you come up with a dashboard. Not only data

tells the story. Things like colours, how you maintain the

real estate of the dashboard, and titles, how good is your

title. I can tell you that just from your title, people get 30 to

40% of what is there in the dashboard. You have to very

carefully choose your title. If you are talking about sales and

if you return something like ‘Profit Margin’ as your title,

people are going to look for something called ‘Profityou’re

your dashboard and there will not be any value for profit

and they’re definitely not going to like it.

And the final one would be the data quality. The data quality

has to be checked not only once or twice, at least thrice,

Page 18: SDS PODCAST EPISODE 87 WITH DEEPAK PRASAD · guys would benefit from Qlik,” and then your goal is for these organizations to adopt these products. Is that correct? Deepak: I would

because when you put in the dashboard, it is like you’re

certifying that this is the dashboard and this is where you

have to derive insights from. And just think about the

scenario where you have sourced the data from the wrong

place and people are making decisions out of that

dashboard. So you have to be very sure of what data you’re

using. That’s very important as well.

Kirill: That’s really cool. Let’s sum it up, these insights. We have

the data-ink ratio, which is actually a cool term. Data-ink

ratio should be increased, should be quite high, meaning

that it shouldn’t have less stuff that doesn’t convey insights

that are auxiliary or they’re just there for visual help. You

should make sure the space between objects is sufficient so

that it all looks good, it doesn’t look like it’s cluttering each

other. Colours are very important, and we have some tools

such as — you just sent me Coolors, so coolors.co or you’ve

got colors.adobe.com. It can help you derive the colours and

make sure it’s colour blind safe. Then we’ve got the title, so

we have to have a good title and data quality.

I like how you put it, that data quality has to be checked at

least three times. You are basically certifying that it’s all

correct and this is where you derive data. I have an

interesting question for you. A lot of times I hear from data

scientists about pie charts, that pie charts are evil and they

should not be used. What’s your opinion of pie charts

because I’ve seen them used quite a lot in BI?

Deepak: There’s also a very good blogger, I’m sure you know him, his

name is Andy Kriebel.

Kirill: Yes, yes. It’s so funny, he’s coming on the podcast very soon.

Page 19: SDS PODCAST EPISODE 87 WITH DEEPAK PRASAD · guys would benefit from Qlik,” and then your goal is for these organizations to adopt these products. Is that correct? Deepak: I would

Deepak: Yeah. So, his tagline is “Friends don’t let friends use pie

charts.” (Laughs) That’s important. Pie chart has its own

way of expressing the information. In my experience, I would

use pie charts in only one instance, which is individual to

whole comparison. Let’s say you wanted to compare what

are all the mobile providers. For example, let’s take Apple,

Samsung, LG, Nokia and so on, and let’s say you want to see

what is Apple’s share and others. Let’s say that Apple will be

35% and rest of all will fall into 65%. That is called

individual to whole comparison. For those alone, I would use

a pie chart. Other than that, if you have more than three

dimensions, I would not suggest a pie chart. Other than

individual to whole, I would not suggest a pie chart

anywhere else.

Kirill: Okay. That’s really cool. I will bring this up with Andy

Kriebel, talk about it more with him. This is an interesting

point. Thanks for sharing that. And what’s your favourite

type of chart?

Deepak: When it comes to charts that are simple, I like the bar chart.

But when it comes to complicated stuff, when you want to

see the distribution, I like box plot more.

Kirill: Okay. Why do you like box plot so much?

Deepak: Box plot tells you a different story. Every time you click on a

box plot chart, it tells you a different story.

Kirill: Okay. By the way, these visualizations, this is the next thing

I want to talk about. These visualizations aren’t just

visualizations. They’re called dashboards for a reason,

because they’re interactive. You create them in a way that

people can click, so when they click on something, the rest

Page 20: SDS PODCAST EPISODE 87 WITH DEEPAK PRASAD · guys would benefit from Qlik,” and then your goal is for these organizations to adopt these products. Is that correct? Deepak: I would

of the dashboard adjusts and talks about that specific part.

For instance, if you have a bar chart for different age

categories, or different age groups of your users or age

groups of your customers, and then the user of the

dashboard click on everybody on the bar that’s 25-35, then

the rest of the dashboard will focus in on everybody who is

25-35.

Tell us a bit more about interactivity. How important is it for

these dashboards to be interactive, and have you noticed

any changes in the behaviour of users of these dashboards

over the recent years? Because it’s becoming more and more

easier to create dashboards which are interactive, I think

people are getting more used to them now.

Deepak: When we talk about interactivity, if you ask me, interactivity

is nothing but asking questions. When we talk about asking

questions, we wanted a technology or a product to remember

what we asked before the second question. For example, I

asked three questions and we wanted the third question to

be answered after considering the first two questions I

asked. This is the power, right? So, when you ask one

question—for example, if I ask the Siri app — I’m talking

about the Siri voice command platform in Apple — if I ask

Siri what is the weather in Sydney, it tells me what is the

weather. And the second question is, should I bring an

umbrella today. So it should consider the weather, which is

my first question, and it should answer the second one also.

So, the correlation is what I’m talking about. This is what I

consider is very important when it comes to Qlik and

Tableau. Also, a very favourite question – I don’t know

Page 21: SDS PODCAST EPISODE 87 WITH DEEPAK PRASAD · guys would benefit from Qlik,” and then your goal is for these organizations to adopt these products. Is that correct? Deepak: I would

whether you would ask it – but I would put it in the podcast:

Everyone always asks me which is better, Qlik or Tableau.

Kirill: Oh, yeah, that’s a good one. So what’s better?

Deepak: That is one question that everyone asks me whether it is in

the interview or whoever I meet and talk about the

visualization tools. According to me, Qlik has its own power

and Tableau has its own power. For Tableau, its power

comes from the drag and drop interface, very intuitive,

people can come up with a dashboard in just two to three

minutes and things like that. When it comes to Qlik—

Kirill: When you’re comparing Tableau versus Qlik, is it QlikView

or Qlik Sense?

Deepak: I would compare — if it is going to be a head-to-head

comparison, I would take Qlik Sense because it follows the

same methodology as well: drag and drop, easy, intuitive.

When it comes to Qlik, the power lies behind what I call a

‘subscripting layer’ where you can blend the data, where you

can play with the data, multiple layers of ETL.

For example, you have [indecipherable], you wanted to make

it as a mail, and you have a particular number you want to

add it up with another number and do some mathematical

expression layer by layer, Qlik is very good at doing it.

Tableau to an extent, yes, but not like Qlik. Qlik, when it

comes to dashboard building and publishing and getting it

to the user, it follows its own pathway, Tableau follows its

own pathway. But the power of Qlik lies in associative

experience.

Page 22: SDS PODCAST EPISODE 87 WITH DEEPAK PRASAD · guys would benefit from Qlik,” and then your goal is for these organizations to adopt these products. Is that correct? Deepak: I would

The associative experience, if you ask me to talk, I will talk

for days and hours. It’s a very beautifully patented one that’s

patented by Qlik. That’s the one thing that will pull a big

crowd into Qlik. Tableau pulls the crowd because of its

intuitiveness and drag and drop interface.

Kirill: Which one would you say is easier to learn for somebody

listening to this podcast who wants to start?

Deepak: That depends. For someone who is listening to the podcast, I

would say—I have a hard and fast rule. If your data lake is

very good, if you feel that your data doesn’t need any

massaging at all, it is already done and if you feel your data

is very good, go for Tableau. If your data needs multiple

levels of cleaning, massaging, and you don’t have a data

warehouse at all, you don’t have a massaging layer in your

enterprise at all, Qlik comes to rescue you. So you directly

connect to an interface, you clean, massage and save

everything in QlikView data format and then you consume it

to the presentation layer. That’s the way.

Kirill: Cool, gotcha. And you mentioned as well, you work with

Power BI. What do you think of Power BI? I ask this question

because I’ve noticed them—it’s a Microsoft product, for those

who don’t know, and it’s free as opposed to Qlik and

Tableau, it has the same goals of what it can do—but what

I’ve noticed is that it has been developing and growing with

huge leaps every single month for the past year or so.

They’ve been releasing updates every month. And it stands

to show, a proof of their growth is how the Gartner’s Magic

Quadrant has positioned them a year ago.

Page 23: SDS PODCAST EPISODE 87 WITH DEEPAK PRASAD · guys would benefit from Qlik,” and then your goal is for these organizations to adopt these products. Is that correct? Deepak: I would

Gartner’s Magic Quadrant is for all products and they have

one for BI products, it comes out in February, and last year

they were somewhere in the middle among everybody else,

but now they’re in the lead alongside Tableau in that Magic

Quadrant. So what are your thoughts and views of Power

BI?

Deepak: For me, Power BI stands great because every two weeks they

give proper updates. And the second thing is the integration

point of view. People want flexibility now. If you say, “This is

the way my product works,” and you don’t get more

flexibility, then people basically don’t like your product. Just

think about Power BI. It can integrate to any Microsoft

products seamlessly. And imagine embedding your

dashboard in your SharePoint. Take any organization. 60%-

70% of our organization is all Microsoft-based. I have

SharePoint in my organization; I have Excel, Microsoft Word,

PowerPoint laying everywhere.

So whenever you talk about BI tools to people, the first

question, the first good question they ask is, “Can I export it

to Excel? Can I export it to PPT?” because that’s what is

going to be shown to all the board members and CXO level

executives. So, when it comes to this, Power BI understand

these things and they export functionality and connecting to

all its database SQL, SSIS, SSRS layers, and DAX cubes. It

clearly understood what it wants. And also, for anyone who

knows Excel, catching up with Power BI is very easy. Just

imagine the number of people who use Excel in this world.

And if you say that will be a very less learning curve if you

know Excel, then who wouldn’t learn Power BI?

Page 24: SDS PODCAST EPISODE 87 WITH DEEPAK PRASAD · guys would benefit from Qlik,” and then your goal is for these organizations to adopt these products. Is that correct? Deepak: I would

That’s the point. It’s about grabbing your share perfectly.

Microsoft did that perfectly, I would say. It clearly

understood who all can be its end user and what other

words can attract people like ‘Excel users’ and ‘Microsoft-

based organizations.’ They can use these words to easily pull

people inside. They’ve clearly concentrated in those areas

like exporting functionalities and connecting seamlessly into

Microsoft and being on cloud, which is a buzzword now

everywhere. If you say, “You can go on cloud in just five days

with our product,” then definitely you get one step ahead

than any other product.

Kirill: Yeah, totally. That’s a pretty solid overview. It will be

interesting to see how all these three compete and other

products compete over the next couple of years. It’s kind of

like a horse race. Every year you check who’s in the front,

who’s in the lead, who has got what new. Yeah, exciting

times.

Deepak: Yeah, did you see that? Yesterday, or I think day before

yesterday, Tableau acquired a company called ClearGraph.

Kirill: No, I didn’t see that. That’s interesting.

Deepak: Yeah. ClearGraph is a company—say you just type ‘Sales by

country’ and hit enter, it will give you a ‘Sales by country’

bar chart just by your search.

Kirill: Nice. That’s really cool.

Deepak: They’re doing a lot of things in natural language, NLP and

text processing. So, the ClearGraph acquisition definitely

shows that all the BI tools’ next mission would be

understanding whatever people type, like Google. So, the

Page 25: SDS PODCAST EPISODE 87 WITH DEEPAK PRASAD · guys would benefit from Qlik,” and then your goal is for these organizations to adopt these products. Is that correct? Deepak: I would

Google-like experience is going to be the next big thing in the

data visualization world.

Kirill: That’s really cool. Then the only think you have to watch is

the correctness of it, right? It’s like is it actually giving you

what you want or something random.

Deepak: Yeah.

Kirill: And what I also like about Tableau is that they have a very

strong user community. There’s lots of bloggers who write

about Tableau, there’s lots of people on the forums, so if you

have any questions you get them answered very quickly. I

don’t think that’s the case for QlikView and Power BI, not yet

anyway. What do you think of that?

Deepak: True, very true. The community and the way they market

their product and the conferences that are being held every

year and the way they promote the conference, I think they

have very good team structure. One team promotes a

community, one team answers all the queries of people, and

the learning community is almost free. You can learn from

zero to hundred, everything for free when it comes to

Tableau.

I accept some mastery tricks that you provide in your Udemy

course, I would say. Other than that, if you want to just

understand the basics and just keep going until even

intermediate/advanced, everything is properly covered in

their course curriculum for the very basic users. But to go to

an advanced level, you need guidance from people who

achieved that already.

Page 26: SDS PODCAST EPISODE 87 WITH DEEPAK PRASAD · guys would benefit from Qlik,” and then your goal is for these organizations to adopt these products. Is that correct? Deepak: I would

Kirill: Yeah, I totally agree with you. I’m not going to argue with

that. I think you can totally get everything for free in the

Tableau courses and online on YouTube. The only kind of

difference and what my courses bring is the element of a

journey and the elements of more applied case studies that

you go through and you practice and so on. It’s kind of a

different approach to education, but yeah, I totally

appreciate and it’s really cool that Tableau provides this

education and that people can pick it up pretty quickly.

Good thing.

I’m cautious of time, we’ve talked a lot about these different

tools and business intelligence. It’s so great to get some of

your insights. I’ve already learned a lot personally. And I

would also like to talk about your personal journey as well.

From your LinkedIn I can see that you only recently joined

ASG Group. How are enjoying it at the company? Do you

enjoy the company culture?

Deepak: Yeah, the company culture is really enthusiastic, energetic,

and more than that. I heard one important statement from

my boss which is listening to people, listening to our

customers. So, when you listen to people, instead of just

talking to them, listening is the one important capability

that every BI consultant should have, which was a good

learning for me when I started this job. When you put

yourself in that perspective, when you listen to people

instead of just pushing whatever you have in your mind, you

will just open up to give more suggestions.

Instead of giving an idea of what a business intelligence

layer does, you will give them an idea that “Your data

Page 27: SDS PODCAST EPISODE 87 WITH DEEPAK PRASAD · guys would benefit from Qlik,” and then your goal is for these organizations to adopt these products. Is that correct? Deepak: I would

warehouse itself has a problem. Do you mind if I take a

look?” Things like that. So if you ask those questions, then

people open up. “Okay, do you want to do some consulting

on data warehouse and give us some insights to what’s

wrong with our data warehouse?” and then let’s go to the

next layer, which is business intelligence. That’s when it has

to start.

So I strongly feel that instead of just selling your single

product, it has to be an adaptation of their very own data

culture. Instead of you just selling, you have to adopt their

data culture and provide an end-to-end data solution. That’s

what ASG is all about and that’s all the services we provide

to our customers. And that’s why people keep returning to

ASG. If you just trace back any people who have worked

with ASG, they would come back again just because of this

quality.

Kirill: That’s fantastic. And I really like what you mentioned about

listening. I think that’s very important. You can save a lot of

time and efforts if you just listen carefully to personal

requirement, and not necessarily just in consulting. Even if

you’re within an organization trying to help somebody, if you

listen to them carefully and not make assumptions about

what they want and what their problems actually are, if you

hear them out you can really save a lot of time by focusing

on the right things.

I’m looking at your LinkedIn again. Throughout your career,

you’ve gone through a huge transformation, a huge growth.

You started as an Assistant System Engineer back in India

and then you had some big roles like Consultant, Associate

Page 28: SDS PODCAST EPISODE 87 WITH DEEPAK PRASAD · guys would benefit from Qlik,” and then your goal is for these organizations to adopt these products. Is that correct? Deepak: I would

Manager, BI Specialist and Senior Technical Consultant for

several years at a time. You obviously have a vision for your

career. You’ve been, as I can see, deliberately selecting these

opportunities and growing and growing.

Now you’re in Sydney, Australia, working for ASG Group and

it sounds like you’re having lots of fun. What would you say

have been the most important qualities for you that helped

you build this career for yourself?

Deepak: What I feel is, from my academics, when I study a topic, I

will not turn my pages until I’m very clear about the topic.

That put me apart from the crowd. During my college or

school days, if you see my answer paper and other answer

papers in my class, people would have answered for 100

mark and score 98 or 99 or even 60 or 50, and if you take

my answer paper, I would have only answered for 60 mark

and I would get all 60. That is one characteristic which has

always put me outside, as an outlier from the total crowd.

So, the way I study is, until I understand a certain topic

completely, I will not move further. Let it be about BI or a

data warehouse or any other topic, if I’m reading about the

topic and if I’m stuck in the second line and if I’m not

understanding the word from the second line, I’ll just Google

about it, read about it, get myself clear, and then I will start

reading the third line. I will not cross the second line until

I’m very clear. That’s one good quality I have, which is

attention to detail.

The way I achieve mastery in any skills I take—for example, I

started my career, as I told you, with Unix, then Oracle, then

Informatica, then Cognos, then MicroStrategy, then

Page 29: SDS PODCAST EPISODE 87 WITH DEEPAK PRASAD · guys would benefit from Qlik,” and then your goal is for these organizations to adopt these products. Is that correct? Deepak: I would

QlikView, then Tableau. So what I feel is an important

quality is your basics, no matter what, always have to be

very strong. Your advanced quality in certain tools or

products can be wavering, but your basics of any product

should be very strong. If your basics are very strong, for you

to reach mastery level is always a cakewalk. But if your

basic itself is not strong, although by mistake or by luck you

reach mastery level, it’s very highly likely that you might fall

down on any day. So I strongly feel if one’s basics are figured

out clearly, then you are very good to go.

Kirill: Fantastic. That’s really cool. On that first one, just to recap,

first one was a very unique quality. I don’t think I’ve

encountered this in person like this, where you will just

focus on that one thing that you’re currently working on and

you will make sure you know it really well and then you only

move forward, and the second one was basics have to be

very strong.

On that first one, I wanted to ask you, have you ever

encountered a situation where you just weren’t able to move

forward, where you came into a roadblock and it was just

impossible to either learn that thing or get that thing done or

whatever you were focused on, there was something

preventing you from doing it? Has that ever happened and

what did you do in that case?

Deepak: Luckily, I’ve not come across this situation. The reason

being is we are wealthy enough as a world, we are wealthy

enough that we have excellent resources available and tools

like Google, where you just type and it gives you whatever

we have. We are not here to invent something new.

Page 30: SDS PODCAST EPISODE 87 WITH DEEPAK PRASAD · guys would benefit from Qlik,” and then your goal is for these organizations to adopt these products. Is that correct? Deepak: I would

Everything is there available on the Internet. For me, at

least, I think if I would have been born before the 1940s, I

would have come across this.

Kirill: Yeah, gotcha. Good point. With Google, you can pretty much

find an answer to anything. Okay, that’s been really cool.

You know, we’re slowly coming to the end of the podcast and

I wanted to ask you, from what you’ve seen in the space of

business intelligence and from the work you’ve done, where

do you think this whole field of data science is going and

what should our listeners look into to prepare for the future?

Deepak: When it comes to the future, the future doesn’t want people

who just have a balance of technology. The future needs

people who understand the technology, who understand the

process, who understand people and deliver something

which balances everything together. We wanted someone

who can listen to the problems and deliver solutions,

custom-tailored solutions according to the need, not the

same one-size-fits-all. It’s old theory now. Everyone needs a

different stitch and everyone wants it in their own way and

you have to make sure you have got the right skills to

provide that.

Kirill: Gotcha. People, process, technology – those are three

important things. Can you elaborate on that a little bit

more?

Deepak: When you want to sell or project some idea about yourself or

any future-proof product you want to come up with, just

imagine your product with certain end users. Any product

that has been built or going to be built without keeping

Page 31: SDS PODCAST EPISODE 87 WITH DEEPAK PRASAD · guys would benefit from Qlik,” and then your goal is for these organizations to adopt these products. Is that correct? Deepak: I would

some end users in mind, the product will definitely not

succeed. And same with the process.

For example, I’m going to come up with a product called a

newspaper. Let’s say that the whole world doesn’t have

something called newspaper for now. If I say that I’m going

to come up with a newspaper now, how many people would

really read a newspaper when all the information they want

is available across the Internet for free? Although you charge

1 cent, do you think people would buy that? No. So when

you come up with a product, or when you come up with a

solution, or any platform or a service or anything, you have

to be very sure of who are going to be your end users and

who are you going to serve and what is the current problem

they are coming across and how are you going to solve it? So

these three things are all I’m talking about: people, process

and technology. It has to be perfectly balanced.

Kirill: Fantastic. Thank you so much, Deepak. That’s really good

insight. We’re going to end on that note. Thank you so much

for coming on the show. A quick question: Where can our

listeners find you, connect with you or get in touch so they

can follow your career further?

Deepak: They can find me at LinkedIn. They can also reach me as a

consultant through ASG.

Kirill: Gotcha. ASG in Sydney and LinkedIn.

Deepak: Yeah, LinkedIn. Just search for Deepak Prasad.

Kirill: We’ll definitely share that. And I have one last question for

you. What is a book that you can recommend to our

listeners that can help them become better data scientists?

Page 32: SDS PODCAST EPISODE 87 WITH DEEPAK PRASAD · guys would benefit from Qlik,” and then your goal is for these organizations to adopt these products. Is that correct? Deepak: I would

Deepak: If you want to become a data scientist, first you have to have

a really good hold of your data. When you don’t have a good

hold of your data, no matter what algorithms you know or

what skills you get for data science, it will go for a toss. So

for data analysis purposes, I strongly recommend a book

“Head First Data Analysis” by O’Reilly. And the second book

I suggest is a book called “Data Smart.” That is for data

analysis as well.

For visualization, I strongly feel there is a very good book

that I will read again and again and again that is called “The

Truthful Art” and “The Functional Art.” There can’t be any

better book than this according to me. And I bought a good

book recently which is called “The Big Book of Dashboards”

which is quite interesting as well.

And for data science—for me, when it comes to data science,

you have to have a good hold of many algorithms and real

use case studies. That will basically come from the “Data

Smart” book itself, but there are many other data science

books called “Doing Data Science” from O’Reilly and that’s a

good place to start. And then once you have decided you’re

going into data science, “Doing Data Science” is a better

start, and then once you’ve chosen which technology you’re

going to take, whether it’s going to be R or Python, according

to that, you have to choose your books.

Kirill: Wow. That’s a whole library there, guys. “Head First Data

Analysis,” “Doing Data Science,” “Data Smart,” “The Truthful

Art,” and “The Big Book of Dashboards.” I actually heard of

that last one, “The Big Book of Dashboards.” I haven’t read it

yet, but somebody on the podcast mentioned it so it must be

pretty good. I’m sure you’re going to enjoy that one. Once

again, thanks a lot, Deepak, for coming on the show. I really

appreciate you coming in and sharing all these insights. It

was very interesting to talk about business intelligence and

different types of tools and approaches, so thanks so much.

Deepak: Thank you, Kirill. Thanks a lot for this opportunity. And

more than me talking, I learned a lot from you as well.

Kirill: Thanks, man. All right, take care.

Deepak: Thanks. Take care. Bye.

Kirill: So there you have it. That was Deepak Prasad from ASG

Group. I really hope you enjoyed today’s episode and that

you picked up some interesting ideas from here, whether it

be about business intelligence or about your career. And

personally, my favourite part was when we discussed the

three pillars that you need to take into account when

deploying business intelligence tools. That is people, process

and technology. And personally, I actually think that it’s not

just relevant to business intelligence, but in many areas of

business, you need to think about these three things, about

people and process and technology and how they all work

together, how people use the technology to execute the

processes that they should be executing, how the processes

are tailored to the people to maximize the power of

technology, or how the technology is selected to help the

people execute the processes. So there’s lots of ways that

these three interact and depending on the current business

situation, it’s important to look at them from different

perspectives through different lenses.
