Introduction to Minitab and Its Statistical Application


Manufacturing Organizations use 6-sigma tools to drive continual improvement in Manufacturing and Production Operations. In the present work environment everyone involved in continual improvement should be equipped or armed with the know how in utilizing 6-sigma tools. However, we will focus on key 6-sigma tools. This course will improve the analytic skill effectiveness in problem solving and implementation of the appropriate tools in the continual improvement process using Minitab 15.


On completion of the program, participants will be able:
  • Understanding Minitab Application
  • Understand and apply the Quality Planning tools
  • Identify and apply the Quality Control tools
  • Identify and utilize Quality Improvement tools
  • How to carry out their Process Capability studies
  • Understand Basic Statistics and Anova

This will enhance participants capability of problem solving and conducting many quality improvement activities using Minitab.
