BUNKING LECTURES

PARETO DIAGRAM“Put your efforts where they will make most

difference”

It is one of the seven basic tools of quality

control.

It is diagram that comprises of a series of

bars arranged in descending order of height,

from left to right and a line graph.

The length of the bars represents the

frequency.

Pareto diagram are used to analyze a

problem and gives a easy way out for

analyzing which problem needs attention

first.

PARETO PRINCIPLE“Don’t just ‘WORK SMART’, work smart on

the right things”

It is also known as the 80-20 rule.

It states that in any set of things few

(20%) are vital and rest (80%) are trivial or

of little significance.

As shown in the figure, the principle

reminds us to focus on the 20% that

matters i.e.20% has more weightage than

80%.

problem.

It breaks the problem into several parts and then finds the most

problematic area.

Shows the path for finding the exact root causes

Helps in improving decision making.
