2. 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 alm o st e ve ry case , 8 0 % o f the
to talpro ble m s incurre d are cause d by 20 % o f the pro ble m cause type , 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 vitalfe w and the use ful
m any“One of the example of Pareto chart is described here
Document 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

OurCurrent problemis “Bunking Lectures”
3. 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

Vital Symptoms Problem Definition Lesson Learned
5. 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.
Lackof 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
6. 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 implimented
Then 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
7. 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
