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

Strengths, limits, and pitfalls.
Six Sigma
- 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.
Watch for
- 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.
Six Sigma level
- 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.
Watch for
- 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.

Contracts Management PlanContracts Management Plan Purpose. Use this plan to define how programme-level contracts will be administered from award through closure. Its purpose is to ensure that contracted deliverables and services meet cost, schedule, benefit and quality requirements while both buyer and seller fulfil their obligations. Application. The plan builds on the procurement management plan and may be maintained aBenefits Realization ReportBenefits Realization Report Purpose. Use this report to show which programme benefits were realised during a defined period, which expected benefits were delayed or missed, and which new benefits have emerged. Each entry should trace to the business case and benefits-realisation plan so decision-makers can distinguish delivered value from completed activity. Application. Benefits become meaningfulKnowledge Management PlanKnowledge Management Plan Purpose. Use this plan to connect programme participants with useful knowledge, subject-matter expertise and the information created across components. Effective knowledge management reduces reinvention and duplicate work, helps people find proven answers quickly and reserves scarce expert attention for problems that genuinely require new thinking. Application. Prepare thProgram Benefits Transition PlanProgram Benefits Transition Plan Purpose. Use this plan to move benefit-enabling outputs, responsibilities and capabilities from the programme into the environment that will use and sustain them. The receiver may be a customer, an operational unit such as product support, customer support or service management, or another programme that is operating or about to begin. Application.
