A Pareto Diagram Example

A Pareto Diagram Example is provided to enhance the pareto principle concept.  

The pareto principle prioritizes information. 

It shows the relative importance of things by charting them from left to right.

In many situations eighty percent of effects are within twenty percent of the components measured.

A Pareto Principle Example

We all use power in our homes or apartments. To save money on this electricity it makes sense to focus efforts on reducing the highest energy users.

This can be done by creating a Pareto Diagram of energy costs and usage.Consider fourteen of the top consumers of electricity in a standard home that is 2,100 ft2 with 8 rooms.

The power consumers are:

• Central heating
• Central air conditioner
• Hot water
• Lights (8 rooms)
• Dryer
• Refrigerator
• Television
• Ceiling fans (3)
• Stove top
• Oven
• Microwave
• Dishwasher
• Computer
• Washer

Following is a breakdown of typical power consumption and cost. This chart shows appliances in order of highest cost and KW electricity usage.#1

Appliance Costs and Power Usage

A Pareto Diagram of Appliance Electric Costs

To conserve electricity and save money, efforts needs to focus on raising the thermostat temperature in the summer months by a few degrees and lowering it by a few degrees in the winter months. Taking a few less hot showers each month will also save electricity.

The Pareto Diagram Example shows that lights are the next biggest users. However, each individual light is a small part of the electric consumption.

There are positive side effects to focusing on a problem. Addressing the important effects often leads to addressing the lesser important ones as well. This is known as the domino effect.

There are several answers to this question:
• To make wise decisions in his or her life.
• To put him/her on the path to knowledge.
• To learn how to approach problems logically and confidently.
• To balance using both the right and left sides of his/her brain.
