Six Sigma
Data-driven methodology for defect reduction and variation control
ISO 22000
International standard for food safety management systems.
Quick Verdict
Six Sigma drives process excellence via DMAIC across industries for cost savings and quality. ISO 22000 ensures food safety through HACCP and PRPs in food chains for compliance and trust. Companies adopt both for operational resilience and market access.

Six Sigma Details
What It Is
Six Sigma is a disciplined, data-driven management framework and methodology for process improvement, reducing variation and preventing defects. It employs DMAIC (Define, Measure, Analyze, Improve, Control) for existing processes and DMADV/DFSS for new designs, targeting 3.4 defects per million opportunities (DPMO) via statistical methods.
Key Components
- DMAIC phases with mandatory deliverables like project charters, SIPOC, VOC-CTQ trees, MSA, root cause verification, FMEA, pilots, and control plans.
- Belt roles: Champions, Master Black Belts, Black/Green Belts.
- Tools: SPC, DOE, Gage R&R, hypothesis testing.
- Governance via tollgates and certification (e.g., ASQ CSSBB with experience/projects).
Why Organizations Use It
- Quantifiable savings (Motorola $17B, GE $1B+).
- Improves quality, efficiency, customer satisfaction across industries.
- Mitigates risks in regulated sectors like healthcare/finance.
- Builds data-driven culture for competitive edge.
- Voluntary for strategic excellence.
Implementation Overview
- Phased: sponsorship, training, portfolio selection, DMAIC execution, sustainment.
- Suits all sizes/industries; integrates with Lean/ISO.
- No universal certification; ASQ/IASSC optional.
- Initial 12-18 months, ongoing via audits/SPC.
ISO 22000 Details
What It Is
ISO 22000:2018 is the international standard specifying requirements for a Food Safety Management System (FSMS). It provides a framework for organizations in the food chain to ensure safe products through risk-based thinking, HACCP principles, and PDCA cycles at organizational and operational levels.
Key Components
- Clauses 4-10 following **High-Level Structure (HLS)context, leadership, planning, support, operation, evaluation, improvement.
- Integrates PRPs, hazard analysis, OPRPs/CCPs, traceability, verification.
- Built on Codex HACCP and management system discipline.
- Certification via accredited bodies with staged audits.
Why Organizations Use It
- Meets regulatory/customer requirements, reduces risks like recalls.
- Enhances supply chain trust, market access (e.g., GFSI).
- Drives efficiency, integration with ISO 9001/14001.
- Builds reputation, operational resilience.
Implementation Overview
- Phased: gap analysis, PRPs/hazard plans, training, audits.
- Applies to all food chain organizations, scalable by size.
- Requires internal audits, management reviews; certification every 3 years.
