Lean Six Sigma

Lean Six Sigma is a management approach to business performance improvement that has blended the two individual specialisms of Lean and Six Sigma. IOM3 is now offering training in Lean Six Sigma methodology through the IOM3 Training Academy.

At a Glance

  • Enhance management approaches with Lean Six Sigma

  • Remove waste and ensure quality delivery

  • Work through the Lean Six Sigma Belt levels

  • Improve processes whilst decreasing costs

  • Acquire knowledge of DMAIC and DMADV methods

Lean Six Sigma is a methodology that relies on a collaborative team effort to improve performance by systematically removing waste and reducing variation. It combines the ideologies of Lean manufacturing/Lean enterprise and Six Sigma to eliminate the different kinds of waste (muda) which are:

  • Transporting

  • Inventory

  • Motion

  • Waiting

  • Over-Processing

  • Over-Production

  • Defects

  • Under Utilisation of employees

Lean Six Sigma is a joint venture of Lean and Six Sigma. While Lean aims to achieve continuous flow by tightening the linkages between process steps, Six Sigma focuses on reducing process variation, thereby enabling a tightening of those linkages. Just like Six Sigma, Lean Six Sigma also uses the DMAIC phases. Lean Six Sigma builds upon the 5S Lean technique used to keep the production workspace in order and the workforce committed. This 5S technique includes the 5 steps described below:

  • Sort – remove unnecessary waste

  • Straighten – everything is in place 

  • Shine – keep the workplace clean

  • Standardise – conform to the guidelines

  • Sustain – maintain steps 1-4

Course Information

Lean Six Sigma provides expertise to its users at various levels.

The first level in the Lean Six Sigma series is the Lean Six Sigma Yellow Belt This is an introductory course that teaches delegates the basics of Lean Six Sigma.

The second stage is the Lean Six Sigma Green Belt. A Green Belt is supposed to be familiar with the concepts of the Yellow Belt, however, the Green Belt covers Yellow Belt concepts within it's course content. A Lean Six Sigma Green Belt certified professional is capable of handling a team of Lean Six Sigma Yellow Belts.

The third phase is the Lean Six Sigma Black Belt.  To qualify for this stage, the delegate must be a Green Belt holder. They should also be capable of handling Green Belt Projects (at least ten of these).

Delegates will become aware of DMAIC and DMADV models. 

DMAIC is a cycle that depicts what happens following changes to a process. DMAIC stands for:

  • Define - the process and problem
  • Measure - the process' current performance
  • Analyse - the process for issues and root cause
  • Improve - determine and apply improvements
  • Control - sustain the improvements

DMADV is the method used for development of existing products. DMADV refers to:

Define - the project purpose and problems, and customer requirements to outline project objectives

Measure - the requirements and scope of the project

Analyse - define performance goals and the impact of processes

Design - come up with specifics and achieve design authentication

Verify - test the design and come to a conclusion

The course is run over two weeks, week 1 covers the Yellow & Green Belt training and then a month later week 2 covers the Black Belt training.  You must have passed your Green Belt training to attend the week 2 Black Belt training.  You don't need to have completed your training with IOM3 but we will need to see evidence that you have a valid Certificate.
