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 methodology rather than a mandated regulation.** Professionally, it applies to enterprises seeking process excellence, particularly in manufacturing, healthcare, finance, and services where leadership commits to deployment. Adoption is driven by internal governance, with roles like executive sponsors and belts establishing de facto requirements. Certifying bodies such as **ASQ** mandate experience (e.g., 3 years for CSSBB) and verified projects, but compliance is organizational and strategic, not legally enforced.

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

**Six Sigma does not require external audits or third-party certification for organizational implementation.** It operates as a de facto standard via internal governance, tollgates, and belt hierarchies. Individual certifications (e.g., **ASQ CSSBB**) involve proctored exams and project affidavits but lack a single global authority. **ISO 13053:2011** provides a formal reference, yet deployments rely on DMAIC artifacts, **SPC**, and control plans for sustainment, with no mandatory external validation.

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

**Six Sigma assessments occur continuously via Statistical Process Control (SPC) and periodic audits tied to project Control phases and organizational maturity reviews.** **DMAIC** projects (typically 4-6 months) end with control plans mandating ongoing monitoring (e.g., control charts for special/common cause variation). Enterprise-level reviews align with management cadences, such as quarterly portfolio audits by **Champions** and annual sustainment checks, ensuring gains persist without fixed universal intervals.

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

**Non-compliance with Six Sigma results in internal failure risks, including >60% project failure rates, unverified improvements, and lost savings.** Without adherence to **DMAIC** tollgates, **MSA** (Gage R&R), and control mechanisms, organizations face process regression, inflated **CoPQ**, and strategic misalignment. No legal penalties apply, but poor governance leads to documented issues like scope creep and weak sustainment, eroding ROI as seen in historical critiques.

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

**Yes, Six Sigma maps effectively to complementary frameworks while standing as an independent methodology.** **DMAIC** integrates with **Lean** for waste reduction, aligning control plans and audits with QMS structures. Statistical tools and governance support broader systems, but mappings require organizational tailoring to avoid overlap.

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

**The first step to implement Six Sigma is establishing executive sponsorship and developing a Project Charter during the Define phase.** This includes business case, problem statement, **SIPOC**, **VOC-to-CTQ** translation, SMART goals, scope, timeline, and resources. **Champions** ensure strategic alignment, preventing the >60% failure rate from poor selection.

What is the primary objective of **PRINCE2**?

**The primary objective of PRINCE2 is to provide a structured project management method for controlled delivery of value through reliable governance, decision rights, and delivery control.** It achieves this via **seven Principles** (e.g., continued business justification, manage by stages), **seven Practices** (Business Case, Risk, Progress), and **seven Processes** (Starting Up a Project to Closing a Project), ensuring projects remain viable, tailored, and exception-managed across varied scales.

Who is legally or professionally required to comply with **PRINCE2**?

**No organizations are legally required to comply with PRINCE2, as it is a voluntary project management standard, not a regulatory mandate.** Professionally, it is adopted by project boards, managers, and teams in public sector, regulated industries (e.g., healthcare, construction), and enterprises seeking governance, with certifications (Foundation, Practitioner) recommended for roles like Executive, Senior User, and Project Manager.

Does **PRINCE2** require an external audit or third-party certification?

**PRINCE2 does not require external audits or third-party certification for projects or organizations.** Compliance is demonstrated through internal adherence to its **seven Principles** as guiding obligations, with management products (e.g., PID, stage plans) providing evidence; individual certifications via PeopleCert validate practitioner competence, but project assurance is handled internally by defined roles.

How often should an assessment for **PRINCE2** be performed?

**PRINCE2 assessments occur at every stage boundary and upon exceptions, enforcing continuous viability checks.** The **Managing a Stage Boundary** process mandates project board reviews of business case, tolerances (time, cost, risk, sustainability), and progress; ongoing monitoring via Practices (e.g., Progress, Risk) ensures **manage by exception**, with formal closure assessment in the Closing a Project process.

What are the consequences of non-compliance with **PRINCE2**?

**Non-compliance with PRINCE2 results in internal governance failures like poor viability checks, uncontrolled risks, and project failure, but incurs no legal penalties as it is not mandatory.** Consequences include sunk costs from absent stage authorizations, weak accountability without defined roles, and reduced success rates versus tailored implementations, undermining strategic delivery.

An **PRINCE2** be mapped to other international frameworks?

**Yes, PRINCE2 can be mapped to other international frameworks through its principle-based, scalable structure and explicit tailoring guidance.** Its governance model (e.g., tolerances, stage gates) aligns with complementary methods like agile (via PRINCE2 Agile), while Practices and Processes support integration without violating core Principles.

What is the first step to begin implementing **PRINCE2**?

**The first step to implement PRINCE2 is the Starting Up a Project (SU) process, creating a project brief from the mandate and assessing previous lessons.** Appoint the Executive and Project Manager, prepare an outline **Business Case**, and plan initiation to ensure prerequisites for controlled governance are established before board authorization.

Six Sigma vs PRINCE2

Q: 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).** This benchmark accounts for a 1.5σ long-term shift from short-term capability. Six Sigma employs data-driven methodologies like **DMAIC** (Define, Measure, Analyze, Improve, Control) for existing processes and **DMADV** for new designs, linking projects to strategic priorities via governance structures including **Champions**, **Master Black Belts**, **Black Belts**, and **Green Belts**. Core metrics include sigma levels, yield (FTY/RTY), and capability indices (Cp/Cpk), prioritizing customer-defined CTQs over universal 6σ targets.
