Category: Measurement Systems Analysis (MSA)/Gage R&R

An essential component of any Six Sigma project is the gage R&R step conducted during the Measure phase. Traditional training will cover the full analysis of variance (ANOVA) of a set of continuous data, an attribute gage R&R for discrete data and the destructive gage R&R. Since it is sometimes difficult to apply these tools […]

In Six Sigma work, practitioners normally are expected to conduct a gage R&R study to verify that that the measurement systems being used are providing measurements free from variations due to repeatability and reproducibility problems. This is usually done in the Measure phase of DMAIC (Define, Measure, Analyze, Improve, Control) prior to data analysis so […]

More than ever, companies today realize the importance of measurement – everything from measuring performance to measuring gap closure – in order to achieve goals. Measurement is the process of estimating the ratio of the magnitude of a quantity to a unit of the same type. A measurement is the result of such a process, normally expressed […]

One of the biggest challenges in making improvements in transactional processes is getting data which can be relied upon. There is an abundance of categorical data in transactional areas – situations where a judgment call is required: Is something right or wrong? Is the application complete? What type of error was made on the request […]
