It allows users to measure, analyze, improve, and control their service, transactional and manufacturing process.

An example of user friendliness is the Two Sample Comparison Test, which automatically tests for normality, equal variance, means, and medians. It also provides rule-based yellow highlighting to aid the users interpretation of the output. Low p-values are highlighted in red indicating that the results are significant.

You can design experiments and "view power analysis" as you design! This allows you to readily see the trade off between the cost of experimental runs/replicates and the corresponding statistical power - before you finalize the design.
