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

**The primary objective of Six Sigma is to reduce process variation and defects to achieve 3.4 defects per million opportunities (DPMO), accounting for a 1.5σ long-term mean 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, tollgates, and belt roles (Champions, Master Black Belts, Black Belts, Green Belts).

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 process improvement methodology without mandatory regulatory enforcement.** Professionally, it is adopted by executives in manufacturing, healthcare, finance, and services—often two-thirds of Fortune 500 firms—for roles like Black Belts requiring ASQ CSSBB certification (3 years experience, verified projects).

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, tollgates, and DMAIC deliverables.** Certifications like ASQ CSSBB (165-question exam, project affidavit) or IASSC provide professional validation under ISO/IEC 17024 accreditation, but organizational deployment relies on internal roles and sustainment mechanisms like SPC and control plans.

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

**Six Sigma assessments should be performed continuously via Statistical Process Control (SPC) monitoring, control charts, and periodic audits to detect special-cause variation.** Projects typically span 4–6 months with tollgate reviews per DMAIC phase; program health is reviewed quarterly by Champions, with maturity evaluations using internal metrics like project Define pass rates and sustainment after 12 months.

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

**There are no legal consequences for non-compliance with Six Sigma, as it lacks regulatory mandates or penalties.** Internal risks include sustained high defects (e.g., >60% project failure rates from poor governance), unquantified Cost of Poor Quality (CoPQ), lost savings (e.g., Motorola's $17B benchmark), and competitive disadvantage in quality-driven sectors.

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

**Yes, Six Sigma can be mapped to other international frameworks through shared elements like process control, audits, and continuous improvement.** Its DMAIC aligns with ISO 13053:2011 guidelines, QMS documentation, and Lean tools (e.g., 5S, VSM), enabling integration for maturity models without universal standardization.

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

**The first step to implement Six Sigma is to secure executive sponsorship and develop a Project Charter in the Define phase.** This includes business case, SMART goals, SIPOC mapping, VOC-to-CTQ translation, scope boundaries, and Champion assignment for tollgate oversight, ensuring strategic alignment before Measure-phase data collection.

What is the primary objective of **AS9120B**?

**AS9120B's primary objective is to establish a quality management system (QMS) for organizations that procure, store, split, and resell aerospace parts without altering product characteristics.** Built on ISO 9001:2015’s 10-clause high-level structure, it adds over 100 aerospace-specific requirements addressing distribution risks like loss of traceability, counterfeit/suspected unapproved parts, documentation errors, and external provider controls to ensure chain-of-custody integrity.

Who is legally or professionally required to comply with **AS9120B**?

**AS9120B applies to stockist distributors, pass-through distributors, and those performing batch splitting in aviation, space, and defense supply chains.** Certification is not legally mandatory but is a commercial requirement imposed by OEMs and primes for supply chain approval, with approximately 2,442 global certifications (836 in the U.S.) as of May 2023 enabling OASIS listing and market access.

Does **AS9120B** require an external audit or third-party certification?

**Yes, AS9120B requires third-party certification through accredited registrars via Stage 1 (documentation) and Stage 2 (implementation) audits per AS9101F, followed by annual surveillance and triennial recertification.** Internal audits are also mandated at planned intervals to verify QMS conformity and effectiveness.

How often should an assessment for **AS9120B** be performed?

**AS9120B requires internal audits at planned intervals to cover all processes annually, plus management reviews at defined intervals aligned with strategic direction.** Performance evaluation (Clause 9) includes ongoing monitoring of KPIs, customer satisfaction, supplier performance, and risk actions, with full recertification audits every three years.

What are the consequences of non-compliance with **AS9120B**?

**Non-compliance with AS9120B results in certification denial, suspension, or withdrawal, plus exclusion from OEM supply chains and OASIS listing.** It risks major audit nonconformities, contract penalties, recalls, legal liabilities for safety incidents, and reputational damage from counterfeit part propagation or traceability failures.

An **AS9120B** be mapped to other international frameworks?

**No, AS9120B FAQs must stand alone without referencing mappings to other frameworks.** It is a standalone IAQG standard tailored for aerospace distribution, with its own clause-specific requirements for traceability, counterfeit prevention, and supplier controls.

What is the first step to begin implementing **AS9120B**?

**The first step is conducting a formal gap analysis against AS9120B clauses using a cross-functional team to identify deficiencies in context (Clause 4), scope, risks, and distributor-specific controls.** Document the QMS scope and justify "not applicable" determinations (e.g., Clause 8.3 design), prioritizing traceability and external provider gaps.
