2. Introduction- What is Pareto
Diagram
Pareto Principle-An Italian economist, Vilfredo
Pareto (1848-1923), postulated that for many events
roughly y 80% of the effects come from 20% of the
causes. This principle is also known as the 80–20
rule, the law of the vital few, and the principle
of factor sparsity.
A Pareto diagram is a type of graph that contains
both bars and a line graph, where individual values
are represented in descending order by bars, and
the cumulative total is represented by the line.
4. Introduction-
Why use a Pareto Diagram
• A Pareto Diagram offers the following
advantages:
Breaks big problem into smaller pieces
Identifies most significant factors
Shows where to focus efforts
Allows better use of limited resources
5. Introduction-How to make a
Pareto Diagram
The steps to construct a Pareto Diagram are:
Step 1 - Record the raw data. List each category and its
associated data count.
Step 2 - Order the data. Prepare an analysis sheet, putting
the categories in order and placing the one with the
largest count first.
Step 3 - Label the left-hand vertical axis. Starting the axis
from 0 to closest greater integer to the largest count.
Step 4 - Label the horizontal axis. Make the widths of
all of the bars the same and label the categories from
largest to smallest.
6. Step 5 - Plot a bar for each category. The height of each
bar should equal the count for that category.
Step 6 - Find the cumulative counts. Each category's
cumulative count is the count for that category added
to the counts for all larger categories.
Step 7 - Add a cumulative line. This is optional. Label the
right axis from 0 to 100%, and line up the 100% with the
grand total on the left axis. For each category, put a dot
as high as the cumulative total and in line with the right
edge of that category's bar. Connect all the dots with
straight lines.
7. Data Analysis
The attendance of a 600 students was observed for a period of a
month to ascertain the classes bunked by students-

9. Analysis of Pareto Diagram
• From the Pareto Diagram, it is clear that Co-
curricular activities, time for self-study and
avoidance of boring lectures are together
responsible for nearly 80% of classes bunked.
Co-curricular
activities, Self study,
Boring lectures
Illness, peer
pressure, enjoyment
etc
10. • Ideally, students should be left with ample time after
the lectures to pursue co-curricular activities.
• The conflict of choosing one over the other should
never arise as both are essential facets of college life.
• Also, there should be free time from all college
activities when students can self-study and rest as
well.
Problem Definition: Ideal
Scenario
• The lectures be engaging to students so the
don’t feel bored, instead be excited on
learning something new.
11. Problem Definition: Real Scenario
• The maximum number
of classes are bunked
due to lack of time
management among
students.
• Lecture time is
compromised to make
time for Co-curricular
activities and Self-
study, making
classroom and other
activities exclusive.
12. • Students will have to
choose lectures over
other important college
activities making it a
lose-lose situation.
• A large number of
students also bunked to
avoid what they felt
were boring lectures,
where they could not
develop interest to
study.
13. • Peer pressure of studies resulting in tension and
bafflement, lack of interest in subject also leads to bunking.
• Students consider the lecture
to be boring. They feel the
information imparted is not
useful or not imparted in an
understandable manner.
14. Lessons Learned
• Pareto diagrams give a sharp insight into the
probable causes of a probable.
• Critical issues are focused by ranking them in
terms of importance and frequency.
• Problems are prioritized to EFFICENTLY
initiate problem solving.
15. Problem Definition: Solution
• The college management and students communicate
to arrange a time table which matches need of all.
• Workshops on time management held so students
can learn how to best utilize time without missing
on classes.
• Workshops for faculty be held on how to present
lectures in a more student friendly manner by using
presentations and animations.
• Weekend be a holiday of two days than just one so
students have more than ample free time.
