Have you seen many out-of-control signals from a variable control chart and cannot find reasons for the occurrences? You are not alone!
Even though traditional variable control charting techniques have existed for over 100 years, some critical mathematical properties of these charts can lead to organizational applications that are wasteful and harmful.
This recorded webinar describes and shows how to address these issues.
This ASQ Austin Section recorded webinar “Why Variable Control Charts Fail and How to Make Them Work for You”:
- Shows how the mathematical properties of some variable control charting techniques can lead to firefighting common-cause variation as though it were special-cause – and how to resolve the problem.
- Shows how to determine if a process response is stable from a customer perspective.
- For stable processes, shows a report-out that includes futuristic expectations, e.g., a non-conformance rate.
- Describes the need to improve a process(es) (e.g., via a Lean Six Sigma project) if a futuristic process-response statement is undesirable (e.g., non-conformance rate).
- Provides and describes a free metric reporting app that offers many advantages over traditional variable control charting methodologies, including no firefighting common-cause variation as though it were special-cause.
- Describes a methodology where an organization can report automatically updated predictive performance metrics throughout its business.
This recorded webinar:
- Not only addresses the selection of subgrouping intervals, it will show how traditional control charts can create false special cause signals that lead to firefighting.
- Shows a better measurement tracking methodology that encourages process improvement when appropriate.
- Shows how the above process output response can be considered stable where process improvement is needed if a 26% non-conformance rate is unacceptable for a specification of 95-105.
