Process capability measures, such as Cpk and Ppk, measure how well your process is performing relative to your customer’s specifications. Let’s review some capability analysis basics and then delve into another capability estimate.
The wait is over! Minitab's latest release is here, packed with powerful new features powered by AI. Unleash the power of your data and solve problems faster and easier than ever—with the trusted accuracy Minitab has delivered for over 50 years.
Why the demand for short production runs? Your customer’s application of Lean principles causes them to request smaller batch sizes which results in the need for shorter production runs and short run SPC.
Globalization and digitalization have intensified competition in manufacturing. Some companies are using Bayesian hypothesis testing to optimize processes and make informed decisions. For example, a production manager could use it to improve the engine-cylinder-head-machining process.
DOE is a method that helps manufacturers improve processes by understanding the relationship between factors and the output. It involves defining the problem, selecting the right design, conducting the experiment, analyzing the results, and implementing changes.
A new method to manage quality must not only improve quality, it must also address areas of waste. If we could detect defects even earlier in the process and given that increasing the number of quality gates is untenable, what else can we do?
In the quality management domain, AI undoubtedly has potential in different areas. It would be easy to think that AI could be a threat to less modern tools like statistical process control or render SPC obsolete.
Regression analysis helps quality teams improve their process standards. In simple terms, it helps these teams understand how variations in the manufacturing process affect the quality of the final product.
