Six Sigma Details
What It Is
Six Sigma is a de facto industry standard and methodology, anchored by ISO 13053:2011, focused on reducing process variation and defects through data-driven decisions. It employs a disciplined DMAIC (Define, Measure, Analyze, Improve, Control) lifecycle for existing processes and DMADV for new designs, targeting 3.4 DPMO after a 1.5σ shift.
Key Components
- Structured DMAIC/DMADV phases with mandatory deliverables like charters, SIPOC, MSA, FMEA.
- **Belt systemChampions, Master/Black/Green Belts for roles and training.
- Statistical tools (SPC, DOE, Gage R&R) and governance (tollgates, control plans).
- Certification via bodies like ASQ CSSBB, emphasizing projects and exams.
Why Organizations Use It
Delivers financial savings (e.g., GE $1B+), risk reduction, customer CTQ alignment. Voluntary but strategic for quality, compliance integration (ISO 9001), competitive edge in manufacturing, healthcare, finance.
Implementation Overview
Phased rollout: executive sponsorship, training, project portfolio, DMAIC execution. Applies enterprise-wide, cross-industry; requires 12-18 months, belts, software like Minitab. No formal audits but internal tollgates ensure sustainment.
FSSC 22000 Details
What It Is
FSSC 22000 (Food Safety System Certification 22000) is a GFSI-benchmarked certification scheme for Food Safety Management Systems (FSMS). Its primary purpose is to ensure organizations in the food chain produce safe food through a unified, auditable framework spanning primary handling, manufacturing, packaging, logistics, and more. It employs a risk-based, PDCA management system approach integrating ISO 22000:2018.
Key Components
- **Three pillarsISO 22000:2018 (clauses 4-10), sector-specific PRPs (e.g., ISO/TS 22002 series), FSSC Additional Requirements (e.g., food defense, fraud, allergens).
- Covers 10+ food chain categories (B-K).
- Built on HACCP principles with layered controls (PRPs, OPRPs, CCPs).
- Certification model via licensed bodies per ISO 22003-1:2022.
Why Organizations Use It
- Meets retailer/buyer demands for GFSI recognition.
- Enhances supply-chain trust, reduces audit duplication.
- Manages risks like fraud, defense, allergens; supports SDGs.
- Builds competitive edge via global acceptance (40,000+ sites).
Implementation Overview
- Phased: gap analysis, FSMS design, training, audits.
- Applies to all food chain sizes/sectors worldwide.
- Requires Stage 1/2 certification audits, surveillance/recertification.
