What is LEAN Six Sigma?
LEAN Six Sigma is a structured and systematic methodology that focuses on customer expectation and eliminates waste and inconsistencies in the current process, product, resources and technology. It is the way to achieve the best possible quality of process (which is 99.99966%, hence Six Sigma) without defects and that improves capability and performance of business, reduces process variations, and more importantly boost customer satisfaction and business profitability.
LEAN Six Sigma adopts a data-driven and statistical process. What “may” seem to be the current practices does not always reflect on the true state of process. LEAN Six Sigma focuses on true (and brutal at times) state of AS-IS process that is backed by data rather than shared perception.

7 Evils of Waste
LEAN Six Sigma always focuses on facts with data and statistics to seek process standardization and identify where the waste is originated from. In the LEAN world, waste is synonymous with Non-Value Added that creates unnecessary bottlenecks in organization’s process. Consequences of the waste may be excessive cycle time, confusion among process owners and team members, high product returns, unbalanced inventory, customer complaints, employee dissatisfaction, etc.
LEAN recognizes that all process waste are originated from single or combinations of the following areas:
Transportation – Movement of products (including email, copied documents, information, etc.) between processes.
Inventory – Work in progress (WIP), finished products (including documents, materials, communication, etc.) that accumulates without reaching the final destination of delivery.
Motion – Movement within a single process
Wait – Idle time caused due to depending on the completion of something/someone’s work.
Overproduction – Producing something BEFORE it is required, and/or produce more than required.
Overprocess – Taking more time and/or effort than required by customer.
Defect – Anything (product, service, communications, documents, etc.) that requires rework, retouch, and repair.
LEAN Six Sigma Process
Lean Six sigma is the methodology that identifies and reduces those waste while establishing standardized end-to-end process by reducing variations.
LEAN Six Sigma follows incremental, procedural and sequential steps that are described as DMAIC. DMAIC stands for Define, Measure, Analyze, Improve and Control. This always should be a team effort led by a LEAN Six Sigma practitioner such as Six Sigma Green Belt and Black Belt.
