To understand the DMAIC Methodology, let’s first take a look at what is Lean Six Sigma. Lean and Six Sigma are both proven approaches that seek to deliver sustainable business improvement. These two approaches were developed independently, but the modern way is to combine them into a holistic approach to solve the problem at hand.
Lean Six Sigma is a philosophy and methodology that combines a customer-oriented mindset to reducing non-value-adding waste (Lean) together with a data-driven approach to eliminate defects and variation (Six Sigma).
Lean Six Sigma provides a structured framework, data-driven analytical and statistical tools, and a common language around problem-solving – from recurring operational problems to achieving transformational change within an organisation.
Lean Six Sigma (LSS) uses the DMAIC methodology for structured problem-solving and process optimisation*.
DMAIC stands for:
Define your customer requirements, agree scope and set clear goals.
Collect data to accurately measure current performance.
Analyse and interpret data statistically to confirm root causes.
Identify, assess and implement the best possible solutions.
Validate the solution/s and apply controls to sustain the benefits.
* A separate Lean Six Sigma methodology is used for new product or process design. This is known as ‘Design for Six Sigma’ (DFSS) and uses the DMADV framework (Define-Measure-Analyse-Design-Verify).
People with different levels of Lean Six Sigma expertise work together to apply the DMAIC methodology. The different levels are known as “Belts”.
