LEAN MANUFACTURING & SIX SIGMA Guide to Business Improvement Tools
Contents Overview of LEAN Manufacturing Overview of Six Sigma PDCA Wheel Six Sigma Roadmap Tool selection guide
LEAN Manufacturing Henry Ford production line to Toyota Production System Methodology spread across industries and countries Production activity that is not important to the customer is seen as waste, and to be reduced / eliminated. Focuses on optimising ‘production flow’. Converts ‘push through to sell’ production to ‘pull through by customer demand’ production.
PDCA Wheel A foundation tool of LEAN to explain to teams how to make process improvements. Plan the improvement Do the trial Check the results Action the new standard Once the new standard is locked in, further improvement activity can occur
Six Sigma ( 6 σ ) Created by Motorola in the 1970’s in response to quality criticisms Heavy on Statistical Process Control and Hypothesis testing Focus is to reduce defects by reducing process variability Quality side tools Acceptance side tools A 6σ process is % accurate (Between three and four defects per million opportunities) Excellence = Quality x Acceptance
