What is the primary objective of ITIL?

The primary objective of ITIL is to provide a set of best-practice guidelines for IT Service Management (ITSM) that aligns IT services with business objectives through the Service Value System (SVS). ITIL 4 (2019) emphasizes value co-creation via 34 practices across general, service, and technical management, incorporating the Service Value Chain's six activities (Plan, Improve, Engage, Design & Transition, Obtain/Build, Deliver & Support) and seven guiding principles like Focus on Value and Progress Iteratively with Feedback.

Who is legally or professionally required to comply with ITIL?

No organizations are legally required to comply with ITIL, as it is a voluntary best-practices framework, not a mandatory regulation. Professionally, IT leaders, service managers, and ITSM practitioners in enterprises adopt it for alignment, with 87% global IT organizations using it; certifications via PeopleCert (Foundation to Strategic Leader) are recommended for roles like Service Owner and Process Owner.

Does ITIL require an external audit or third-party certification?

ITIL does not require external audits or third-party certification, as it is a flexible framework of guidelines rather than a certifiable standard. Organizations may pursue ISO/IEC 20000 certification, which aligns with ITIL practices, but ITIL itself focuses on internal adoption through self-assessment, gap analysis, and continual improvement.

How often should an assessment for ITIL be performed?

ITIL assessments should be performed continually as part of the SVS's Continual Improvement practice, with formal gap analyses conducted during initial implementation and periodically thereafter. The seven-step Continual Service Improvement (CSI) model from ITIL v3, integrated into ITIL 4, recommends ongoing measurement of KPIs like incident resolution times and change success rates.

What are the consequences of non-compliance with ITIL?

There are no legal consequences for non-compliance with ITIL, since it imposes no regulatory mandates or penalties. Organizations risk operational inefficiencies, such as increased downtime, higher costs, and misaligned services, but adopters report benefits like 38:1 ROI (DISA case) and 20% faster incident resolution.

Can ITIL be mapped to other international frameworks?

Yes, ITIL can be mapped to other international frameworks through its alignment with standards like ISO/IEC 20000 and integrations with Agile, DevOps, Lean, and SRE. ITIL 4's 34 practices and four dimensions (Organizations & People, Information & Technology, Partners & Suppliers, Value Streams & Processes) facilitate compatibility without direct mappings specified in the framework.

What is the first step to begin implementing ITIL?

The first step to begin implementing ITIL is Project Preparation, securing executive sponsorship and defining scope via the ten-step roadmap. This involves developing a business case, conducting an ITIL assessment, and starting where you are, per the guiding principle, to tailor the SVS to organizational context.

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 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 organizations 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 market access; as of early 2026, over 2,400 global certifications (over 800 in the U.S.) underscore its role as a de facto qualification for ASD distributors excluding those altering product or performing MRO.

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

Yes, AS9120B requires third-party certification through accredited bodies following a two-stage audit process (Stage 1 documentation review, Stage 2 on-site effectiveness verification). Certification leads to IAQG OASIS listing for visibility; surveillance audits occur annually, with recertification every three years per AS9101G rules.

How often should an assessment for AS9120B be performed?

AS9120B requires internal audits at planned intervals to cover the QMS annually, plus management reviews at defined intervals aligned with strategic direction. Performance evaluation (Clause 9) mandates ongoing monitoring of KPIs like nonconformities, customer satisfaction, and supplier performance, with full system reassessment via surveillance audits post-certification.

What are the consequences of non-compliance with AS9120B?

Non-compliance with AS9120B risks commercial exclusion from OEM supply chains, loss of OASIS listing, and audit nonconformities leading to certification suspension. It exposes organizations to product safety liabilities, recalls, reputational damage, and contract penalties from primes requiring certified distributors.

Can AS9120B be mapped to other international frameworks?

Yes, AS9120B aligns directly with ISO 9001:2015’s high-level structure, enabling seamless mapping of its 10 clauses. Aerospace additions (e.g., counterfeit prevention, traceability) build on this baseline, facilitating integration while standing as a standalone distributor QMS.

What is the first step to begin implementing AS9120B?

The first step is conducting a gap analysis against AS9120B clauses using a cross-functional team to assess current processes. Document scope (Clause 4.3), justify “not applicable” determinations (e.g., 8.3 design), and prioritize distributor risks like traceability and supplier controls to create an implementation backlog.
