Six Sigma Details
What It Is
Six Sigma (ISO 13053:2011) is a de facto management framework for quantitative process improvement. It focuses on reducing defects to 3.4 DPMO via data-driven methods, primarily DMAIC (Define, Measure, Analyze, Improve, Control) for existing processes and DMADV for new designs.
Key Components
- DMAIC phases with mandatory deliverables like project charters, SIPOC maps, Gage R&R, FMEA, control plans.
- Belt roles: Champions, Master Black Belts, Black/Green Belts.
- Metrics: sigma levels, DPMO, Cp/Cpk.
- Governance: tollgates, statistical tools, SPC. Certification via ASQ/IASSC with project requirements.
Why Organizations Use It
Drives financial savings (e.g., GE $1B+), customer satisfaction, risk reduction. Voluntary but strategic for quality leadership, compliance integration (ISO 9001). Builds data culture, competitive edge across industries.
Implementation Overview
Phased rollout: executive sponsorship, training, project portfolio, DMAIC execution. Applies to all sizes/industries; 12-18 months initial, ongoing sustainment via audits/SPC. No universal certification; body-specific (ASQ CSSBB).
TOGAF Details
What It Is
TOGAF® Standard (The Open Group Architecture Framework) is a vendor-neutral enterprise architecture framework and methodology. Its primary purpose is to design, plan, implement, and govern enterprise-wide change across business and IT. It employs an iterative, tailorable Architecture Development Method (ADM) as its core approach.
Key Components
- Core pillars: ADM (10 phases including Preliminary, Vision, Business/Data/Application/Technology Architectures, Migration, Governance, Change Management), Content Framework (deliverables, artifacts, building blocks), Enterprise Continuum, Reference Models (TRM, SIB, III-RM), and Architecture Capability Framework.
- Supported by Content Metamodel for entities/relationships.
- No fixed controls; focuses on governance, reuse, and maturity models.
- Certification via Open Group paths for practitioners.
Why Organizations Use It
- Aligns strategy with IT execution, reduces duplication/costs, accelerates delivery via reuse.
- Enables risk management, compliance, vendor neutrality.
- Builds stakeholder trust through governed, traceable architectures.
- Provides competitive edge in transformations, interoperability.
Implementation Overview
- Phased/iterative ADM application with tailoring.
- Key activities: maturity assessment, governance setup, pilots, repository build, training.
- Suited for large enterprises across industries; scalable.
- Voluntary adoption; practitioner certification recommended.
