Question
Statistical process control (SPC) is the use of statistics to monitor and improve the quality of a process, such as manufacturing an engine part. In SPC, information about a process is gathered and used to determine if a process is meeting all the specified requirements. One tool used in SPC is a control chart.
You need to do the following:
Search the Internet, your textbook, or other materials to learn more about control charts. Explain how control charts can be used to detect processes that are possibly out of statistical control.
Identify the warning signs that are used to determine an out of control process.
Give two examples where control charts could be used to improve quality.
Explanation / Answer
Product responses are measurements made on the product for purposes of controlling the process or controlling the product to be shipped. These measurements are normally measured off-line, e.g., in the laboratory. Examples include purity, color, bulk density, etc. Control charts should be used to monitor important product responses.
