How SQC is used in real life

Explain how SQC is used in real life
Provide applications by approaching a specific case from a theoretical and practical point of view.
Address the application of SQC to a carefully selected process,
product, or system. The implementation of the SQC is a systematic approach that requires
using a set of statistical and optimization tools and many more. Many of the theoretical basis
of these techniques and tools are covered in the course textbook (chapters 1-15).
