Essential Out-of-Control Criteria for Process Analysis PPT

This PPT slide, part of the 103-slide Six Sigma - Process Capability Study PowerPoint presentation, presents a structured overview of the out-of-control criteria as defined by Walter Shewhart in the 1920s, which are commonly utilized in Minitab for process analysis. It outlines specific criteria that help identify when a process may be deviating from expected performance, signaling potential issues that require attention.

The criteria are categorized into distinct sections, each addressing different aspects of process control. For instance, "Criteria 1: Outlier" focuses on identifying data points that significantly deviate from the norm, indicating potential anomalies. "Criteria 3: Process Trend" examines patterns over time, highlighting trends that could suggest underlying problems in the process.

The slide also details several specific tests that can be performed to evaluate these criteria. Each test is associated with a designated value, K, which represents the threshold for determining whether a process is out of control. For example, one criterion states that if one point exceeds K standard deviations from the center line, it indicates a potential issue. Other criteria assess sequences of points, such as whether multiple points fall on the same side of the center line or if there are consistent increases or decreases.

This structured approach allows organizations to systematically evaluate their processes, ensuring that any deviations are promptly addressed. The clarity and organization of the criteria make it a valuable resource for those looking to enhance their process capability and maintain operational excellence. Understanding these criteria is essential for any organization aiming to implement effective quality control measures.
