Pareto diagram is also known as Pareto chart, Pareto analysis & it was named after Vilfredo Pareto

The Pareto diagram is a graphical overview of the process problems, in ranking order of the most frequent, down to the least frequent, in descending order from left to right

In this way the chart visually depicts which situations are more significant

Pareto Diagram is based on Pareto’s Law which states that in a lm o s t e v e ry c a s e , 8 0 % o f the to ta l p ro ble m s incurre d a re c a us e d by 2 0 % o f the p ro ble m c a us e ty p e , therefore by concentrating on the major problems first, you can eliminate the majority of your problems

Juran changed the phrase describing the Pareto principle to " the v ita l fe w a nd the us e ful m a ny “One of the example of Pareto chart is described hereDocument related customer complaints is broken down into six categories

If all complaints causes equal distress to customer working on quality certificates would have most impact

Introduction Symptoms Stratification Vital Symptoms Problem Definition Lesson Learned

Our Current problem is “Bunking Lectures”

In Pareto analysis first step is finding all the reasons that are causing the given problem, like in this case of bunking lectures there are various reasons for students to bunk lectures

Data is collected from 120 students regarding reasons for Bunking Lectures

Basically stratification is the sorting of data according to certain variables or criteria

Stratification can provide an indication of which characteristics are associated with the phenomenon that you are trying to explain. By stratifying data, a problem-solving team can identify the key problem categories to focus their efforts

With the help of Minitab and given data this is Pareto diagram

The bold line indicating at what point you've reached 80% cumulative percentage—everything to the left of that line are your 20% vital few problems to focus on, while the remainder on the right are trivial

Introduction Symptoms Stratification Vital Symptoms Problem Definition Lesson Learned

As stated in Pareto Law there are some vital symptoms that accounts for 80% of problems so we can eliminate most of the problems only by focussing on these few vital symptoms. In our case vital symptoms are-Late Wakeup : One of the major reason behind the bunking classes is late wakeup of

students. It is the habit that causes every 4th student to get bunk his lectures. There are many reasons behind late wakeup of students like lack of time of sleep due to late night parties, late night studies, lots of assignment etc.

Lack of strictness regarding attendance : Most of students bunk their classes because there is no strict rules in colleges/schools regarding attendance so student takes it lightly as they don’t have to face any consequences because of bunking lectures if there would be strict rules for attending classes then definitely bunking of classes will be reduced

Dislike towards the subject : Subjects in which students don’t have any interest they don’t prefer to attend classes of that subject. The solution for this problem might be teaching the subject in more creative and effective way so that study become more interesting and student don’t find the subject boring

Fun: At teenage most of the students are not serious about study. They are bit careless about the classes & they always wants to have fun so they go out with friends and roam around. One more reason for bunking the classes is that they do not get time for having fun because of lots of assignment & other works. The solution for this problem can be teacher should make the classes fun & interesting so that students can have fun simultaneous with study

In a problem we need to find what are all the factors that are causing it by finding the causes behind the problem we can define it and focus on the major causes to reduce or eliminate the problem

In this case the problem is “Bunking Lectures by the student” so we found out the different causes behind it like Lack of strict rules regarding attendance,Going out with friends,Dislike towards the subject,Peer pressure,Late wakeup etc.

After finding these causes we need to prioritize these causes on which we should to get maximum benefit by putting minimum effort

Biometric attendance system should be implimentedThen we need to study the selected causes that are majorly affecting the problem and then find out how to remove these causes

For example we can take the cause “Late wakeup” which is affecting about 25% students so what are the reasons behind late wakeup like lack of time of sleep due to late night parties, late night studies, lots of assignment etc. so how can we eliminate these causes by teaching them proper time management so that they can schedule everything according to requirement and follow it

First & foremost important lesson learned is what is Pareto diagram, how to draw it & lot of important information about it

This method is an extremely useful way to identify the most critical aspects on which to concentrate

In Six sigma advanced Pareto charts are particularly useful in the analyse phase

It can also be used to aid project selection and to prioritize in the Measure Phase

It vastly improve outcomes with relatively little effort because we have to focus on few causes to solve majority of problems so it helps in saving lot of time

It also helps a team communicate the rationale for focusing on certain areas

It is very easy to understand and apply

It can be applied to any type of problem whether it is business related problems or personal problems or any type of problem
