Statistical Process Control - SPC
Duration – 1 day
Overview
Uncertainty lies all around us and affects everything we do, making it impossible to predict with 100% accuracy what will occur in the future. The role of statistical methods is to bring some order to this apparent chaos and hopefully begin to control our processes better. With SPC we can reliably assess the performance of any process, monitor it statistically and take steps to control it better.
Key Outcomes
Delegates will leave the programme understanding the basic principles of statistical methods and how they apply to process control. They must also know how to implement a suitable sampling and measuring system and then how to construct and monitor appropriate control charts. Delegates will experience a range of data presentation methods and will be given opportunities to perform the measurements, calculations and data presentation themselves – please bring a calculator!
