Document Summary

Product features determine to a large degree the price that a company: freedom from deficiencies is the quality aspect for which. Ability to minimize these deficiencies has an important influence on manufacturing is responsible can charge for its products. Process capability output materials, and so on: random 2. Random variations: )n any manufacturing operation, variability exists in the process, manufacturing variations can be divided into two types, caused by factors such as human variability, variations in raw. Random variations typically form a normal statistical distribution. When the only variations in the process are random, the process is. It is when the process deviates from this normal operating condition that variations of the second type appear said to be in statistical control. Assignable variations: an exception from normal operating conditions due to operator mistakes, defective raw materials, machine malfunctions, and so on random variations. Tolerances and costs causing the output to deviate from the normal distribution.
