Process Capability
This source outlines a three-session programme focused on determining and improving process capability, often associated with Six Sigma methodologies. The initial session introduces the process model, the relationship between Key Process Input Variables (KPIV) and Key Process Output Variables (KPOV), and the importance of measurements, including the concept of normal distribution and 3-Sigma vs 6-Sigma performance. Participants engage in an exercise using a catapult (X-Pult) to identify process variables and collect data. The second session reviews control charts, distinguishing between common cause and special cause variation, and explains process capability through the Cpk index. The final session concentrates on root cause analysis, developing improvement action plans, and implementing these changes, again using the catapult exercise to demonstrate measurable improvements in process capability.
