Introduction to Statistical Process Control
Quality and productivity are the lifelines of any industry in the global economy, with customers consistently seeking assurance that products and services adhere to optimal standards of quality.
Statistical Process Control (SPC) plays a pivotal role in quality management by offering objective evidence to manage and oversee the performance of manufacturing processes and the quality of final products.
Managers responsible for product or service development need a thorough understanding of statistical tools for SPC analysis to monitor process output that impacts quality.
They must also be equipped with quantitative reasoning skills to interpret statistical process control findings or evaluate interpretations made by others effectively.
