Implementing Statistical Process Control (SPC) requires planning, commitment, teamwork, and an understanding of the processes and the measurement system before control charts can be used effectively. Novice SPC users often use incorrect charting methods, which cause the process to appear out of control when it is not. Consequently, novices may waste time tracking special causes when the out-of-control points are actually the result of a measurement error or an invalid subgrouping scheme.
This paper presents a ten-step SPC implementation plan that minimizes non-value-added effort and reduces implementation time:
