Six Sigma
Data-driven methodology for defect reduction and variation control
FDA 21 CFR Part 11
FDA regulation for electronic records and signatures equivalence.
Quick Verdict
Six Sigma drives voluntary process excellence via DMAIC across industries, while FDA 21 CFR Part 11 mandates electronic record integrity controls for life sciences compliance. Companies adopt Six Sigma for cost savings and quality; Part 11 to avoid FDA penalties and ensure data trustworthiness.

Six Sigma Details
What It Is
Six Sigma is a data-driven process improvement framework, anchored by ISO 13053:2011, focusing on reducing variation and defects to achieve near-perfect quality. Its primary scope spans manufacturing, services, healthcare, and finance, using statistical methods for breakthrough performance.
Key Components
- DMAIC cycle (Define, Measure, Analyze, Improve, Control) and DMADV for new processes.
- Belt roles: Champions, Master Black Belts, Black/Green Belts.
- Metrics like 3.4 DPMO, capability indices (Cpk), SPC.
- Governance via tollgates, charters, FMEA, control plans. Certification through bodies like ASQ, emphasizing projects and exams.
Why Organizations Use It
Drives financial savings (e.g., GE $1B+), customer satisfaction, risk reduction. Voluntary but strategic for competitiveness, compliance integration (ISO 9001), and sustained gains amid >60% failure risks without leadership.
Implementation Overview
Phased rollout: executive alignment, training, project portfolio, DMAIC execution, sustainment. Suits all sizes/industries; 12-18 months initial, ongoing via audits/SPC. No mandatory certification, but ASQ/IASSC for credibility. (178 words)
FDA 21 CFR Part 11 Details
What It Is
FDA 21 CFR Part 11 is a U.S. federal regulation establishing criteria for electronic records and electronic signatures to be considered trustworthy, reliable, and equivalent to paper records and handwritten signatures. It applies to FDA-regulated industries using electronic systems for predicate rule records. The approach is risk-based, with controls for closed (§11.10) and open (§11.30) systems, narrowed by 2003 FDA guidance exercising enforcement discretion on some elements while enforcing core controls.
Key Components
- Subparts: General provisions, electronic records (validation, audit trails, access), electronic signatures (manifestation, linking, uniqueness).
- ~20 core controls including system validation, secure audit trails, authority checks, training, and signature non-repudiation.
- Built on predicate rules (e.g., CGMP); no formal certification, but compliance via validation and inspection readiness.
Why Organizations Use It
- Mandatory for life sciences firms relying on electronic records to meet FDA predicate rules.
- Mitigates enforcement risks (warnings, holds); enables paperless operations, data integrity, faster inspections.
- Builds trust, supports quality systems, competitive edge in regulated markets.
Implementation Overview
- Risk-based CSV (GAMP5): scoping, validation (IQ/OQ/PQ), SOPs, training, supplier governance.
- Applies to pharma, devices, biotech; phased (6+ months); FDA inspections verify compliance.
