Performance metrics for processes are an area of much regulatory interest currently. There isn’t always a readily available clear definition of what is needed, however, and guidance from regulators is ...

Manufacturing quality evaluation is a critical discipline that focuses on assessing a process’s ability to produce outputs within pre‐defined tolerance limits. Recent advances combine traditional ...

Repeatability means the ability to produce parts that have identical properties. As with other manufacturing processes, this capability is very important in injection molding because it has a crucial ...

In recent years, a number of process capability indices that have been proposed in the research literature are gradually being introduced in applications. As shown in this example, you can compute ...

Process design experimental data and risk assessments are used to predict expected process performance and establish process performance qualification acceptance criteria. Per ICH Q8, the aim of ...

Quality costs may consume 25% of total revenues in manufacturing businesses, mostly from rework, scrap, warranty, product-liability claims, and recalls. The Six Sigma quality initiative helps ...

Standard capability indices such as C pk are generally considered meaningful only if the process output has a normal (or reasonably normal) distribution. In practice, however, many processes have ...
