Operations

Six Sigma

A data-driven quality method that uses a defined improvement cycle and trained roles to reduce defects and process variation.

Operations

A process-capability indicator that translates observed defects and opportunities into a sigma level.

Choice logic

Six Sigma

Resolve a clearly bounded quality problem in a production process.

Six Sigma level

Answer the performance question: “How capable are our processes of delivering error free work?”

Extracted signals

Secure sustained executive sponsorship before scaling the programme. GE’s experience in the 1990s illustrates how a firm wide priority, maintained over several years, can embed the method. Senior leaders normally need a steering mechanism, champion training—often two days—and Six Sigma measures integrated with operating plans.
DMAIC defines the overall route, with detailed tools and decisions inside every stage. Consistent execution is one reason the method gained influence. Six Sigma programmes therefore use formal training and belt terminology to signal practitioner capability:
Black Belt : leads problem solving projects and trains or coaches project teams.

Do not under resource training or attach a broad improvement assignment to people’s existing workload without creating capacity. Six Sigma works best on a carefully circumscribed process where the team can investigate defects rigorously. Used merely as a general metaphor for quality, it loses the precision that gives it value.

Select Six Sigma projects from strategic priorities. A smaller number of material processes will usually create more value than numerous bottom up projects aimed only at convenient, local savings.

Do not confuse cost reduction with strategic performance. Some celebrated adopters reported major savings while still performing poorly in the market; process efficiency cannot compensate for weak strategic choices.
