Statistical Process Control


The ultimate goal of every manufacturing company is to achieve total customer satisfaction. One of the key initiatives in achieving this goal is through the introduction of Statistical Process Control (SPC).   The understanding of variation, its source and how to control the variation is the fundamental in making sure that the manufacturing process is stable. Through the introduction of statistical process control (SPC), it will prompt the user when there is out of control situation.  This course will introduce the participants to basic understanding of statistic, perform hand –on measurement system analysis, conduct process capability study and establish an effective Statistical Process Control (SPC) program. 

On successful completion of the course, the participants will be able to:

  • Describe the overall concepts of variation to the process, fundamental statistics and measurement system.
  • Describe the key elements and importance of an effective Statistical Process Control (SPC) program.
  • Construct control charts for variables data (X-bar-R, and X-mR) and attribute charts (p, np, c, and u). 
  • Outline the steps in implementing and maintaining the SPC program.
