Any help using Minitab? Design of Experiments / Developing Y=f(x) modelsĭesign of experiments or process modelling requires a lot of iterative experiments. I want to optimise processes or formulations. Refer eight rules of special cause, to understand processes better than before. Control charts, given in this software, covers almost all requirements of analysis. Once we are able to identify special causes, controlling or isolating them is easy - and leads to true improvement of processes. That's because, most of the time "special causes" hide themselves amongst the noise of common causes.Ĭontrol charts enables identification of special causes, and narrows the time window to help understand and identify special causes. Beyond a point, it becomes difficult to link defects to their causes, hence reducing defects beyond that seems difficult. If you are a quality professional, probably one of your focus area is to reduce defect generation in your processes. Next, in list of recommendation is the Control Chart section. I am familiar with basics statistics - what next? Control Charts If you are starting your journey in Six Sigma, and decide to use Minitab in your Six Sigma journey - we highly recommend you take our online certificate exam: " Minitab proficiency for Six Sigma Yellow Belt", available on Leandigit eCourse website.
Most business users get a formal Six Sigma training or certification at this stage. If you enjoy problem solving using basic statistics, gradually you can learn more advances statistical tools and use them when you need. This should help you start of the ground. Proportion tests for percentage defectives.

Why do we need Minitab, when I can use Excel? Statistics has now moved beyond the desk of the mathematicians into the hands of shop floor engineers.

Minitab was one of the earliest software to focus on graphical user interface, and making statistics fun to learn, and easy to apply. Hence, most business users stayed away from applying statistical concepts. That was because, statistical analysis required lengthy and difficulty calculations, and the results were not very intuitive to understand. Prior to Minitab, application of statistics to solve business problems was not very popular.
Minitab is a statistical software that uses graphical user interface to make statistical analysis easy to apply and interpret. What is Minitab, and why is it so popular?
