- 3 day(s)
- Aimed At
-
This course is aimed at supervisors, managers, purchasing personnel, manufacturing engineers, quality engineers, program managers, and others responsible for product quality improvement, variability reduction, and cost reduction.
- Prerequisites
-
The course assumes a process, industrial, manufacturing, inspection, quality assurance, or engineering background.
- Course in a Nutshell
-
Statistical Process Control is a comprehensive and intensive 3-day training program that presents the essential elements of an effective Statistical Process Control program. The course focuses on understanding the basics, identifying objectives, SPC implementation, and realizing the benefits this magnificent process management system offers.
This course develops and presents a results-oriented roadmap for implementing an effective Statistical Process Control program.
- Customize It!
-
Whatever the nature of your system and industry, we will customize the course to meet your specific needs and concerns. Here are some of the ways in which we can tailor the course to help you get more out of it:
- Add a “workshop day” to the course to allow the participants to work together to analyze Statistical Process Control issues specific to your organization. The workshop day can be scheduled a few weeks after the course to allow time for applying the technologies presented in class under an experienced practitioner’s guidance.
- Schedule post-class follow-up consultation for ongoing Statistical Process Control program improvement.
- Learn How To
-
- Develop an effective Statistical Process Control system.
- Objectively identify Statistical Process Control opportunities.
- Work together to implement and improve your Statistical Process Control program.
