Understanding Statistical Process Control (SPC)
SPC is a statistical method used to monitor and control a process to ensure that it operates at its full potential. By using data collected from various stages of production, organizations can identify variations in processes and take corrective actions before defects occur. The AIAG SPC Manual provides essential guidelines and tools for implementing SPC effectively.
Key Concepts of SPC
1. Variation: Understanding the difference between common cause variation and special cause variation is crucial. Common cause variation is inherent to the process, while special cause variation arises from external factors.
2. Control Charts: Control charts are graphical representations used to monitor process stability over time. They help identify trends or shifts that may indicate a need for intervention.
3. Process Capability: This concept measures how well a process meets specified limits. Capability indices such as Cp, Cpk, Pp, and Ppk are essential in assessing process performance.
