Brief Information
´ All presented here is related to (quantitative) data.
´ However, analytics can be either qualitative or quantitative data (or both).
Analytics
´ Why, as PM, do we need to do analysis?´ Because analytics is one of MANY skills needed by a PM.
´ Here I will just explain two experiments to be analyze:´ Results of feature developed
´ Results of feature enhanced
Principle of Doing Analytics
´ Always test it, more about this later.
´ MVP! You can measure better with MVP.´ Beware of MVP, it should be Minimum and Viable both.
Principle of Doing Analytics
´ Put the tracker everywhere so you have better analytics.´ When it’s written everywhere, it does mean everywhere.
´ “Easy” case is when seeing the whole funnel, not acquisition vs activation only (e.g., sessions vs transactions), but also sessions for each page.
´ Difficult case, when seeing a form, not only see “how many visiting the form” vs “how many finished filling the form”, but also see the drop/exit rate for each field.
Principle of Doing Analytics
´ Be skeptical
´ Be aware of correlation trap, a.k.a. cum hoc ergo propter hoc.´ When we find any correlation, make sure that it’s causation (or not).
´ Case in point, Bukalapak in 2014, #pelapak vs #trx.
´ When having a causation, there are 3 possible cases.
Principle of Doing Analytics
´ Remember of the pirate metrics of a startup´ AARRR – Acquisition, Activation, Retention, Revenue, Referral
´ There are two approaches on this:´ If you know exactly where you want to fix a thing, get focused on it
´ If you are not sure or don’t know, check every part of the metrics, fix the one having lots of low-hanging-fruit enhancement.
´ At one time (define it by yourself, be it week, 2 weeks, sprint, month, or whatever) just get focused on one or two out of those five metrics.
´ Too much focuses = no focus at all.
Tools for Analytics
´ Google Analytics
´ Google Tag Manager
´ Google Search Console (GWT) especially if your products involve search engine a lot
´ Mixpanel
´ Some analytics tool for qualitative data can as well be used if you’re executing qualitative analytics
Testing
´ Same questions for analytics skill applies here as well, PM does need testing skill as one of a lot of skills he needs to master.
´ There are other advantages:´ Being more independent from data people.
´ Getting respected. One of the easiest ways to gain respect from people around is by speaking their language. Hence, understanding the (general) language of data is important.
Types of Testing
´ Historical Testing
´ On-off Testing´ Quite similar to historical testing
´ AB testing / Multivariate testing´ Multivariate testing is just AB testing with more variants (more than two)
´ When not to use AB testing?
Some tips for doing A/B Testing´ Make sure that your A/B testing is 100%
random.
´ A/B testing should be done at least one week, because each day is unique.
´ Wait for enough confidence level (usually 90/95/99%) before deciding.
´ If it’s possible, always run the test AFTER the winner is decided.
´ Measure MORE than one metric.
Some extra notes regarding A/B Testing
´ To be able to do A/B testing properly, make sure these four property supports:´ Resource – time, money, etc
´ Tool - next slide
´ Focus – because sometimes doing A/B testing will make tasks executed a bit slower
´ People – it’s not enough to have data-mindset on only data, product or even engineering people, it needs to be spread widely on every part of the company, even to the C-levels.
