Determining Process Performance and Capability in Six Sigma

In any improvement initiative, organizations must determine whether their existing processes meet the targets and specifications demanded by the customer, or by the business. Measuring and analyzing the capability and performance of a process under review enables organizations to numerically represent and interpret its current state, and to report its sigma level. When done correctly, process capability analyses enable Black Belts to precisely assess current performance in light of future goals, and ultimately, to determine the need and targets of process improvement. Process capabilities can be determined for normal and non-normal data, variable (continuous) and attribute (discrete) data, and for long- and short-term alike. This course explores key considerations and calculations used in determining process capability and performance. This includes choosing parameters, verifying the stability and normality of a given process, and gathering and interpreting capability and performance data using common indices. The course also explores the special treatment of non-normal data and attributes data in the context of a capability study and long-and short-term capability. This course is aligned with the ASQ Certified Six Sigma Black Belt certification exam and is designed to assist learners as part of their exam preparation. It builds on foundational knowledge that is taught in SkillSoft’s ASQ-aligned Green Belt curriculum.
