This slide give the basic introduction to 80-20 rule and Pareto Chart which is used to pin-point the major reason among the pool of the same that leads to students bunking their classes. Team members- Silky Jain Anubha Shukla Sneh Nidhi

2.  Just the observation, not the law.
 20 and 80 must not necessarily add to 100.
 The 80/20 Rule means that in anything a few (20 percent) are vital
and many(80 percent) are trivial.
 20% of the input creates 80% of the result
 In a company, 80 percent of the sales will come from 20 percent of
the sales staff.
 20 percent of the staff will cause 80 percent of the problems, but
another 20 percent of the staff will provide 80 percent of the
production. It works both ways.
 Serve as a daily reminder to focus 80 percent of our time and
energy on the 20 percent of our work that is really important.

3.  Reminds us to focus on the 20 percent that matters because those 20
percent produces 80 percent of the desired result.
 20% of workers contribute 80% of results: Focus on rewarding these
employees.
 20% of bugs contribute 80% of crashes: Focus on fixing these bugs first.
 20% of customers contribute 80% of revenue: Focus on satisfying these
customers.
 The point is to realize that you can often focus your effort on the 20%
that makes a difference, instead of the 80% that doesn’t add much.

4.  Graphical overview of the process problems.
 Ranking order - most frequent, down to the least frequent.
 Bar chart arranged in descending order of height from left to right.
 Bars on left relatively more important than those on right.
 Illustrates the frequency of fault types, i.e. fault is most serious or most
frequent offender.
 Separates the "vital few" from the "trivial many" .
 Breaks a big problem into smaller pieces and identifies the biggest
contributors.
 Based on pareto principle- 80% of the output in a given situation or system
is produced by 20% of the input.
 An example is…

7. 1. Identification of major causes/reasons leading to lecture bunk.
2. Observe the Frequency of occurrence of each cause.
3. Calculation is done to obtain Cumulative Frequency from the
frequencies.
4. Computation of Cumulative Percentage.
Through these, following table was crafted

11.  Transportation Problem
As majority of the students rely on availability and punctuality of the
transport to reach class on time.
 Poor Content of the lecture
Because of dull content and/or way of instruction, students loose their
interest in the lecture.
 Insomnia
Sleeping late at night not only disturbs metabolic clock but also causes
missed lectures.

12. •Irresponsible college administration.
•Inadequate transportation facility.
•No fix timing of public transport.
•Disappointing transportation facilities for the
colleges in remote areas.
Transportation problem
•Lecturer is not interested.
•Lecture not planned by lecturer.
•Not having proper command on the subject.
Poor content of lecture

13. • Late night parties, watching movies and gossip.
• Late night study.
• Completion of assignment and file record at the
last moment.
• Surfing internet or chatting with friend late at
night.
• Excessive use of mobile phone and gadgets,
addiction to gaming.

14.  The Pareto Principle helps us to realize that the majority of results
come from a minority of inputs.
 Help us to put our effort on 20% that makes a difference, rather
than on 80% that don’t add much.
 Assist us to resolve factors which do not require as much attention
and time as others.
 For instance, while preparing a report, it is the drafting process that
contributes the most. Although the report will be tagged ‘complete’
only after final fair copy has been prepared, but it is the content
that is of value which is assembled while preparing draft.
