About this Course

The Lean Six Sigma Analyst training complements the skills gained from the Green Belt Practitioner (LSSGBP) course, with advanced tools for quantitative process improvement.

The course can be attended following on from the Green Belt Practitioners course or as a stand-alone course for those wanting to know more about statistical analysis using Minitab®.

In the course we consider more advanced techniques required to help analyse process data, interpret the results and apply inferential techniques to measure the risk associated with change and improvement decisions.

Upon completion of LSSA delegates are fully equipped to tackle more complex business problems and complement qualitative analysis from the Green Belt (process modelling, VOC analysis, Value analysis, Root cause analysis) with formal statistical methods (estimation, hypothesis testing, correlation analysis).

Theoretical concepts are supported by hands on exercises using real project data.

Software used is Minitab®

On the last day of the training, delegates sit on the Statistical Analyst certification exam.
