SPC Briefing for Managers

SPC Workshop for End-Users

This 2-hour briefing is for managers and executives who wish to learn what SPC can do for them and what they, as managers, must do to get started with minimum cost and effort. It will also describe how to sustain success by applying a change strategy. Special consideration is given to the characteristics of the company's processes and the demands that these processes place on SPC.


This 1-day workshop is geared for individuals and teams who have a direct role in supporting processes within their organization. Emphasis is on practical skills and knowledge that pertain to end-users rather than statisticians. You will learn how to identify control points, collect data, and interpret patterns and trends. You will also learn how to use SPC in support of continuous process improvement.
