If you do not specify both LSL and USL, the variable _CP_ is assigned a missing value. The process capability index C pk is computed as If you specify only USL, the index C pk is computed as You can ...

Process capability indices (PCIs) have long served as crucial metrics in assessing the performance and quality of manufacturing processes. Recent advances in statistical estimation techniques have not ...

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 ...

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 ...

The author outlines key considerations for carrying out a structured approach to monitoring process performance and ensuring product quality. Routine, ongoing assessment of process performance and ...
