Lean Six Sigma Tools for Internal Audit

Course Description

Print-friendly Course Description and Outline

The fundamental objective of the Six Sigma methodology is the implementation of a measurement-based strategy that focuses on process improvement and variation reduction. Six Sigma seeks to improve the quality of process outputs by identifying and removing the causes of defects (e.g., errors) and minimizing variability in business processes by using a set of quality management and statistical tools.

The purpose of this course is to expose participants to some of the basic Six Sigma tools that can be used during the planning and fieldwork phases of an internal audit to enhance audit effectiveness, provide deeper insight into business operations, and identify process streamlining opportunities. These tools can be used independently or in conjunction with existing audit methodologies, tools, and techniques. Participants will have the opportunity to practice and apply the skills learned during the course through case study and exercises, which should enable them to integrate the tools and techniques into their audit engagement activities.

This course is appropriate for auditors at all levels.
