Abstract | This paper proposes process quality indices (PQIs) for the assessment of quality levels associated with unilateral as well as bilateral specifications. To ensure the reliability of quality assessments, we employed the lower confidence limit of the indices to serve as a standard and developed a process quality analysis chart (PQAC) for the simultaneous evaluation of larger-the-better, smaller-the-better, and nominal-the-best quality characteristics with the aim of identifying the causes of sub-standard quality. The resulting chart also provides a valuable reference by which to guide efforts aimed at improvement.
