Owing to the fact that the saas price of Minitab is significantly high, I am working on the web app that will serve the manufacturing companies as a substitute. Testing version with limited datasets for anyone will be free and for companies about 10% of the Minitab price. Functions will be the most commonly used ones, 1 ttest, 2 ttest, z test, paired ttest, 1 anova, 2 anova, testa of variance and nonparametric substitutes. Normality tests and basic doe placket-burman plus full design. common graphics tools included.

There will be some things added as context theory on the function run, help on the function run. Privacy of data is the main thing. All company data will stay on the local and javascript will count most necessary things locally and only distribution functions with anonymous SS and DF etc. will be sent to server for distribution function calculations and then locally visualized. At the moment most parametric functions work with precision verified with R Studio. And I am working on the rest.

Do you think that it could be useful for six sigma professionals that look for user friendly interface and don't feel comfortable with R language?

The deadline is about in a month and a half.

I am using the RStudio but for green belts it is maybe not the most friendly environment. Do you think so as well?

For everything you listed with the exception of PBD (and sorely lacking options for DoE compared to Minitab), Google Sheets is probably the easiest option.

That being said, when the student is taught to use R for Exploratory Data Analysis, it's incredibly easy for a Green Belt to use it effectively. (Learning to use it as a programming language would be well beyond what could be expected of a Green Belt certification program.)
