Module 2.5 ;You Are Here;Goals;Introduction to Concepts;Process Capability Review;Uses of Process Capability Indices;The Basic Setup;To increase a process capability, you have to decrease the process variation. Less variation provides
Greater predictability in the process, allowing us to make reliable forecasts, meet schedules for orders, etc.
Less waste and rework, which lowers costs
Products and services that perform better and last longer
Happier customers;;Context
The normal distribution provides the basis for an introduction to process capability
Definition
A probability distribution where the most frequently occurring value is in the middle and other probabilities tail off symmetrically in both directions. This shape is sometimes called a bell-shaped curve.
Characteristics
Curve theoretically does not reach zero; thus the sum of all finite areas total less than 100%
Curve is symmetric on either side of the most frequently occurring value
The peak of the curve represents the center, or average, of the process
But for all practical purposes, the area under the curve represents virtually 100% of the product the process is capable of producing;The Normal Curve and Process Capability;Defining a Normal Curve;Normal Distribution;Review: Equations for Mean and Standard Deviation;Calculating Mean and Standard Deviation;Practice: Calculating Standard Deviation (optional);Answers: Calculating Standard Deviation;Normal Curve Probabilities;Converting to Standard Normal;Z Table;Exercise;;Process Capability Assessment Flow Chart;Process Capability Assessment Flow Chart, cont.;Process Capability Assessment Flow Chart, cont.;Process Capability Assessment Flow Chart, cont.;The Issue of Stability in Process Capability Studies;Glossary of Terms;Common Process Capability Indices: The C and P families;Process Capability Statistics;Capability Sixpack;Capability Sixpack, cont.;2;Judgment of Process Capability, pH Example;Exercise: Assess Process Capability;Exercise: Assess Pro
