Document Summary
Inspection means examining the output of a process to determine whether it is acceptable. Key issues in inspection include: where to inspect in the process, how often to inspect, whether to inspect on-site or in a laboratory. Statistical process control focuses on detecting departures from randomness in a process. Two basic tools of process control are: control charts, run tests. Process capability studies are used to determine if the output of a process will satisfy specifications. They can provide valuable information for managers in terms of reducing costs and avoiding problems created by generating output that is not within specifications. Quality control"s purpose is to identify a process that also exhibits non-random (correctable) variation based on sample statistics (e. g. , sample means) obtained from the process. Control charts and run tests can be used to detect non-random variation in sample statistics. It is also advisable to plot the data to visually check for patterns.
