Bunking College Lectures

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.

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.

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.

80% problem correspond to

20% factors

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

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.

• 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

• 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.

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.
