2. Transactional Black Belts Are Different! Transactional Black Belts are different! We advance this argument based on our experience that Transactional Black Belts often encounter environments where no process is defined, often must define and re-design a whole process versus a step in a manufacturing process, find cycle time is a more useful overall measure versus defect count for project selection, and find changes are hard to reverse in a human related environment versus the more reversible machine or material-related environment. Learn more details in this presentation and how this training will have more impact on your results.

5. What is Process Capability? The Manufacturing Perspective Example Output from Manufacturing Capability Study The focus of process capability analysis in manufacturing systems is to predict the likelihood of producing products which do not meet specifications.

7. Short Term (Inherent) Capability The Manufacturing Perspective One “generic” component of variation is referred to as “Short Term” in the world of Six Sigma. Six Sigma was originally developed around the concepts of manufacturing capability and more specifically, machine capability. Sometimes we refer to this as “inherent” capability. We estimate inherent capability by determining the standard deviation of parts produced over a very short period of time, hence the term Short Term Capability.
8. Long Term Capability (Performance) The Manufacturing Perspective The other “generic” component of variation in Six Sigma is referred to as “Long Term”. It is assumed that anything that occurs over the long term is related to factors other than the internal properties of the machine itself. Factors like material variation, fluctuations in temperature or humidity, different people, and tool wear are all potential causes of long term variation. Estimates inherent machine capability Estimates degree of process control Estimates variability in final, delivered parts

24. Time as a Process Metric A critical characteristic of time as a process metric is its expected shape. Most manufacturing measurements are expected to follow a normal distribution. In turn, most manufacturing oriented capability indices assume that the measurements are normal and use statistics which are appropriate to that distribution. Time, however is often not normal. In fact, for a good process, time should be extremely “not normal”! Expected Distribution Shapes Manufactured Characteristic Cycle Time
