Six Sigma
Data-driven framework for process variation reduction
ISO 27017
International standard for cloud-specific information security controls
Quick Verdict
Six Sigma drives process excellence through DMAIC for all industries, while ISO 27017 provides cloud security controls within ISO 27001 ISMS. Companies adopt Six Sigma for defect reduction and savings; ISO 27017 for shared cloud responsibility and compliance assurance.

Six Sigma Details
What It Is
Six Sigma is a de facto management framework and process improvement methodology, anchored by ISO 13053:2011 for quantitative methods. It focuses on reducing process variation, preventing defects, and achieving data-driven excellence through DMAIC (Define, Measure, Analyze, Improve, Control) for existing processes and DMADV for new designs. Core approach emphasizes statistical rigor and governance.
Key Components
- DMAIC/DMADV phases with mandatory deliverables like charters, SIPOC, MSA, FMEA, control plans.
- **Belt systemChampions, Master Black Belts, Black/Green Belts.
- Metrics: 3.4 DPMO, sigma levels, Cp/Cpk.
- Governance: tollgates, SPC, audits; certification via ASQ/IASSC BoKs.
Why Organizations Use It
Drives financial savings (e.g., GE $1B+), customer satisfaction, risk reduction; voluntary but strategic for competitiveness across industries. Builds data culture, sustains gains, enhances reputation.
Implementation Overview
Enterprise deployment via phased rollout: sponsorship, training, project portfolio, DMAIC execution. Suits all sizes/industries; 4-6 month projects, ongoing maturity. No universal certification, but ASQ CSSBB benchmarks competence.
ISO 27017 Details
What It Is
ISO/IEC 27017:2015 is a code of practice extending ISO/IEC 27002 with cloud-specific guidance. It provides implementation advice for information security controls in cloud services, focusing on shared responsibilities between cloud service providers (CSPs) and customers (CSCs). Its risk-based approach adapts 37 existing controls and adds seven new ones for cloud environments.
Key Components
- Guidance across 14 domains mirroring ISO 27002, like access control and operations security.
- Seven cloud-specific CLD controls (e.g., CLD.6.3.1 for roles, CLD.9.5.1 for segregation).
- Built on ISO 27001 ISMS; no standalone certification—assessed within 27001 audits.
Why Organizations Use It
- Addresses cloud risks like multi-tenancy and virtualization.
- Meets procurement demands and supports GDPR/CCPA alignment.
- Enhances risk management and builds customer trust.
- Provides competitive edge for CSPs via audit-ready evidence.
Implementation Overview
- Integrate into existing ISO 27001 ISMS via risk assessment and control mapping.
- Key activities: define shared responsibilities, configure VM hardening, enable monitoring.
- Suits CSPs, CSCs across sizes/industries; global applicability.
- Audit via certification bodies as 27001 extension (9-12 months joint).
