1. Write a note on the following: a. Pareto chart

Pareto Chart

Vilfredo Pareto (1848-1923) discovered that:

· 80% of the wealth in Italy was held by 20% of the population

· 20% of customers accounted for 80% of sales

· 20% of parts accounted for 80% of cost, etc.

These observations were confirmed by Juran (1960) and resulted in what is known as the Pareto Principle.The Pareto Principle states that:

4. What is a Control chart? Describe the structure and construction of control chart.

Meaning and Concept of Control Charts

A control chart is a graphical representation of the collected information. The information may pertain to measured quality characteristics or judged quality characteristics of samples. It detects the variation in processing and warns if there is any departure from the specified tolerance limits.

The control limits on the chart are so placed as to disclose the presence or absence of the assignable causes of quality variation. This makes possible the diagnosis and correction of many productions troubles and often brings substantial improvements in product quality and reduction of spoilage and rework. Moreover, by identifying certain of the quality variations as inevitable chance variations, the control chart tell when to leave the process alone and thus prevents unnecessarily frequent adjustments that tend to increase the variability of the process rather than to detect it.
