Lean Six Sigma certifications

IASSC LSS

Six Sigma is a business management strategy - originally developed by Motorola in 1986 - that seeks to improve the quality of process outputs by identifying and removing the causes of defects and reducing variability in those processes.

The strategy utilises a set of quality management methods, including statistical methods, and creates an infrastructure of people within the organisation (Black Belts and Green Belts) who are experts in these methods. Each Six Sigma project follows a defined sequence of steps and has quantified financial targets – like reducing cost or increasing profit.

Lean Six Sigma is the Six Sigma business management strategy combined with Lean – a methodology based on two principles: continuous improvement and respect for people. To work effectively within an environment that utilises Lean Six Sigma, you’ll benefit from building your skills through Lean Six Sigma training.
