Using Lean Control Tools and Maintaining Controls in Six Sigma

Candidates seeking Six Sigma Black Belt certification, quality professionals, engineers, production managers, frontline supervisors, and all individuals charged with responsibility for improving quality and processes at the organizational or departmental level, including process owners and champions

Proficiency at the Green Belt level with concepts related to measurement systems analysis and control plan development as scoped in the ASQ – Six Sigma Green Belt Body of Knowledge (BOK)

Expected Duration
121 minutes

In the final stages of the Six Sigma DMAIC methodology, teams need to control the improved processes in order to sustain improvement gains. Process control includes applying tools to continuously monitor and maintain each improved process, and to prevent it from reverting to its previous state. Apart from the statistical process control, there are a number of other Six Sigma and Lean tools to help to this end.
This course introduces basic control tools commonly used in Lean Six Sigma projects. Specifically, it explores how total productive maintenance (TPM) promotes shared responsibility for maintaining process gains, and how the visual controls provide at-a-glance information about process performance. In addition, this course highlights the need to re-analyze the measurement system after improvement solutions are implemented, and provides guidelines for drawing conclusions from this. It tours the key elements of a vital tool for maintaining controls – the control plan – and explores the steps for developing an effective plan. This course is aligned with the ASQ Certified Six Sigma Black Belt certification exam and is designed to assist learners as part of their exam preparation. It builds on foundational knowledge that is taught in SkillSoft’s ASQ-aligned Green Belt curriculum.


Lean Control Tools in Six Sigma

  • recognize statements that reflect the goals and features of total productive maintenance (TPM)
  • sequence the steps recommended for implementing total productive maintenance (TPM)
  • sequence descriptions of the stages of small group development
  • recognize the basic goal of a sample element from visual controls
  • recognize the advantages of using basic visual controls rather than sophisticated IT tools

Maintaining Controls

  • recognize how various factors influence the decision to improve a measurement system in a given scenario
  • recognize why it is necessary to perform a measurement system re-analysis after a successful process improvement initiative
  • recognize the effect of reduced process variation on measurement system performance metrics
  • identify characteristics of a control plan
  • match control plan improvement goals with tasks carried out at each stage
  • recognize examples of information typically included in a control plan
  • identify actions involved in transferring responsibility from the Six Sigma team to the process owner
