Improvement Tools & Techniques

Advanced Statistical Process Control (SPC)

Introduction

Dr. Walter A. Shewhart of Bell Telephone Laboratories developed the first Control Chart in the early 1920s. Since then, Control Charts have been used by industries worldwide as the means for controlling and monitoring the stability of key process parameters. Statistical process control or SPC for short is a statistically-based family of tools used to monitor, control and improve processes.

In recent years, the demand for control charts as a process improvement tool has been tremendous, and it has become one of the core tools to be deployed in organizations implementing ISO/TS16949 systems. Herein, selecting and setting up the right type of SPC control chart for a given process is crucial to getting the most benefit from this improvement tool.

Benefits of Implementation

The organisation will be able to:

• assess objectively the stability of the manufacturing processes
• know when not to adjust the process parameter to avoid over-adjustment to the process
• calculate and assess the manufacturing process capability
• integrate and deploy SPC in their organization’s management system
