Six Sigma
Data-driven methodology for defect reduction and variation control
REACH
EU regulation for chemicals registration, evaluation, authorisation, restriction
Quick Verdict
Six Sigma drives voluntary process excellence through DMAIC across industries, while REACH mandates chemical safety registration in EU. Companies adopt Six Sigma for cost savings and quality; REACH ensures legal market access and risk mitigation.

Six Sigma Details
What It Is
Six Sigma is a de facto industry standard (ISO 13053:2011 provides formal guidance) for process improvement via data-driven methods. It focuses on reducing variation and defects using DMAIC (Define, Measure, Analyze, Improve, Control) for existing processes and DMADV for new designs, targeting 3.4 DPMO.
Key Components
- Structured DMAIC lifecycle with tollgates and deliverables like charters, SIPOC, FMEA.
- Belt roles: Champions, Master Black Belts, Black Belts, Green Belts.
- Statistical tools: MSA (Gage R&R), SPC, DOE, hypothesis testing.
- Governance via executive sponsorship; certification via ASQ/IASSC (experience/projects required).
Why Organizations Use It
Drives financial savings (e.g., GE $1B+), customer satisfaction, risk reduction. Voluntary but strategic for competitiveness; integrates with Lean/ISO 9001. Builds data culture, stakeholder trust.
Implementation Overview
Enterprise deployment: pilot projects (4-6 months), scale via training/PMO. Applies to all sizes/industries; no mandatory certification but ASQ recommended. Phased: alignment, training, execution, sustainment.
REACH Details
What It Is
REACH (Regulation (EC) No 1907/2006) is a directly applicable EU regulation governing the Registration, Evaluation, Authorisation and Restriction of Chemicals. Its primary purpose is to ensure a high level of protection for human health and the environment from chemical risks by shifting responsibility to industry for generating and managing safety data. Scope covers substances, mixtures, and certain articles across the supply chain; it employs a risk-based approach with tonnage-triggered obligations.
Key Components
- Four pillars: Registration (>1 tonne/year dossiers), Evaluation (dossier/substance checks), Authorisation (SVHC permissions via Annex XIV), Restriction (bans/limits via Annex XVII).
- 17 Annexes detailing data requirements, SDS rules, exemptions.
- Built on precautionary principles, PBT criteria; no certification—continuous compliance via ECHA databases.
Why Organizations Use It
- Legal mandate for EU market access; avoids fines, seizures.
- Manages supply chain risks, enables substitution.
- Builds stakeholder trust, ESG alignment, innovation via safer chemicals.
Implementation Overview
- Phased: inventory, gap analysis, dossiers, monitoring.
- Applies to manufacturers/importers/downstream users in chemicals/manufacturing; EU/EEA geography.
- No certification; national enforcement, self-audits essential. (178 words)
