The document discusses Pareto charts and their use in identifying the most important sources of problems or causes. It then provides an example Pareto chart analyzing sources of garbage in a city. The chart shows that the top 5 sources - Paper and Paperboard, Food Scrap, Yard Trimmings, Plastics, and Metals - account for over 50% of the garbage. Therefore, focusing efforts on these top sources would be most effective in reducing the overall garbage in the city.

3. • A pareto chart, also called a pareto distribution diagram,
was named after vilfredo pareto has both lines graph and
bars.
• The bars represent the individual values in the
decreasing order from left to right and the line
represents the cumulative total.
• The pareto chart provides a graphic depiction of the
pareto principle, which states that 80% of the output is
produced by 20% of the input.
4. • In simple words 80% of total problems are caused by
only 20% of input factors.
• Applications of Pareto Chart:
Used to analyze data about the frequency of problems
or causes in a process.
Used when there are many problems or causes and
you want to focus on the most significant.
Used while analyzing broad causes by looking at their
specific components.
5. SURFACE WATER
CONTAMINATION
Waste that end up in water bodies
negatively change the chemical
composition of the water. Technically,
this is called water pollution. This will
affect all ecosystems existing in the
water. It can also cause harm to animals
that drink from such polluted water.
SOIL CONTAMINATION
Hazardous chemicals that get into the soil
(contaminants) can harm plants when
they take up the contamination through
their roots. If humans eat plants and
animals that have been in contact with
such polluted soils, there can be negative
impact on their health.
POLLUTION
Bad waste management practices can
result in land and air pollution and can
cause respiratory problems and other
adverse health effects as contaminants are
absorbed from the lungs into other parts
of the body.
LEACHATE
Liquid that forms as water trickles
through contaminated areas is called
Leachate. It forms very harmful
mixture of chemicals that masy result
in hazardous substances entering
surface water, groundwater or soil.

for 80% of garbage in the city and which needs to
be focused.

12. We learned the concept of ‘vital few and the useful
many’, according to which one need to focus on
those 20% factors which contribute to the 80% of
the output.
We came to know about the major source of
pollution and garbage in the city.
We also realized on which factors we need to focus
in order to lower down the garbage level in the city.
13. We realized how important is ‘Pareto Chart’ as a
quality tool.
Very helpful in decision making.
Pareto Analysis not only shows us the most
important problem to solve, it also gives us a score
showing how severe the problem is.
