What is the primary objective of **Six Sigma**?

**The primary objective of Six Sigma is to improve process performance by reducing variation and defects to achieve 3.4 defects per million opportunities (DPMO), accounting for a 1.5σ long-term shift.** This data-driven methodology employs DMAIC (Define, Measure, Analyze, Improve, Control) for existing processes and DMADV for new designs, linking projects to strategic priorities via governance, belts (Champions, Master Black Belts, Black Belts, Green Belts), and metrics like sigma levels, Cp/Cpk, and financial returns.

Who is legally or professionally required to comply with **Six Sigma**?

**No organizations are legally required to comply with Six Sigma, as it is a voluntary, data-driven methodology rather than a mandated regulation.** Professionally, it is adopted by executives in manufacturing, healthcare, finance, and services for C-suite leaders, Champions, and belts (e.g., ASQ CSSBB requires 3 years' experience and verified projects) to drive ROI, with two-thirds of Fortune 500 firms deploying it by the late 1990s.

Does **Six Sigma** require an external audit or third-party certification?

**Six Sigma does not require external audits or third-party certification, operating as a de facto standard via internal governance and tollgates.** Certifications like ASQ CSSBB (165-question exam, project affidavit) or IASSC provide credentials under ISO/IEC 17024 accreditation, but deployment relies on internal roles, DMAIC deliverables, and sustainment via SPC/control plans.

How often should an assessment for **Six Sigma** be performed?

**Six Sigma assessments should be performed continuously via SPC monitoring, control plans, and periodic audits, with projects scoped to 4-6 months and tollgate reviews at each DMAIC phase.** Program health reviews occur quarterly through executive steering, tracking sigma levels, DPMO, and sustainment to prevent regression.

What are the consequences of non-compliance with **Six Sigma**?

**Non-compliance with Six Sigma carries no legal penalties, as it is voluntary, but results in missed opportunities like sustained defects, higher COPQ, and failure rates exceeding 60% from poor governance.** Organizations risk operational losses (e.g., rework, customer churn) without leadership sponsorship, project discipline, and controls.

An **Six Sigma** be mapped to other international frameworks?

**Yes, Six Sigma maps effectively to frameworks like ISO 13053:2011, which formalizes its processes.** DMAIC aligns with QMS controls (e.g., process mapping, audits), Lean for waste reduction, and regulated systems via FMEA, MSA, and documentation for audit readiness.

What is the first step to begin implementing **Six Sigma**?

**The first step to implement Six Sigma is developing a signed Project Charter in the Define phase, outlining business case, SMART goals, scope, VOC-to-CTQ, SIPOC, timeline, and executive sponsorship.** This establishes tollgate governance and aligns with strategic priorities.

What is the primary objective of **ISO 26000**?

**ISO 26000 provides guidance on social responsibility to help organizations contribute to sustainable development through transparent and ethical behavior.** Published in November 2010 and confirmed current in 2021, it defines social responsibility as an organization's accountability for its impacts on society and the environment, considering stakeholder expectations and international norms. It structures this via **seven principles** (accountability, transparency, ethical behavior, respect for stakeholder interests, rule of law, international norms, human rights) and **seven core subjects** (organizational governance, human rights, labor practices, environment, fair operating practices, consumer issues, community involvement/development), applied holistically through stakeholder engagement and integration.

Who is legally or professionally required to comply with **ISO 26000**?

**No organization is legally required to comply with ISO 26000, as it is voluntary guidance applicable to all types regardless of size, location, or sector.** It targets private, public, and non-profit entities—including SMEs, multinationals, hospitals, schools, and charities—for professional adoption to enhance sustainability performance, risk management, and stakeholder trust. Compliance is driven by strategic needs like ESG reporting, procurement expectations, or investor demands, not mandates.

Does **ISO 26000** require an external audit or third-party certification?

**No, ISO 26000 explicitly prohibits external audits or third-party certification.** Its Scope states it "is not a management system standard" and "not intended or appropriate for certification purposes," deeming such claims a "misrepresentation." Credibility relies on self-assessment, transparent reporting (including shortfalls), stakeholder engagement, and alignment with frameworks like GRI, using ISO's Communication Protocol for claims.

How often should an assessment for **ISO 26000** be performed?

**ISO 26000 recommends periodic self-assessments at appropriate intervals aligned with organizational context and stakeholder needs.** It lacks fixed frequencies, emphasizing continuous integration via Plan-Do-Check-Act cycles. Best practice involves annual reviews of core subjects' relevance/significance, materiality assessments, and performance reporting to capture achievements, shortfalls, and improvements.

What are the consequences of non-compliance with **ISO 26000**?

**There are no direct legal consequences for non-compliance with ISO 26000, as it imposes no requirements.** Indirect risks include reputational damage, lost market access, investor scrutiny, or failure to meet procurement/stakeholder expectations, potentially amplifying exposures in human rights, labor, or environmental areas under separate regulations.

An **ISO 26000** be mapped to other international frameworks?

**Yes, ISO 26000 aligns with frameworks like OECD Guidelines, UN Global Compact, GRI, and UN SDGs via official ISO linkage documents.** It complements them as a unifying SR reference, supporting ESG materiality, human rights due diligence, and reporting without replacing certifiable standards.

What is the first step to begin implementing **ISO 26000**?

**The first step is recognizing social responsibility and engaging stakeholders (Clause 5) to identify relevant core subjects and issues.** Map organizational impacts, conduct a materiality assessment, and prioritize via stakeholder dialogue to ensure context-specific application.
