PMBOK Details
What It Is
PMBOK® Guide (Project Management Body of Knowledge) is a PMI standard and guide codifying generally accepted project management practices. It standardizes governance, planning, execution, and closure across industries. Scope covers all project types; approach shifts from process-heavy (6th ed.) to principle- and outcome-based (7th/8th eds.) with tailoring emphasis.
Key Components
- 5 Process Groups: Initiating, Planning, Executing, Monitoring/Controlling, Closing.
- 10 Knowledge Areas: Integration, Scope, Schedule, Cost, Quality, Resources, Communications, Risk, Procurement, Stakeholders.
- ~49 processes with ITTOs; 12 principles, 8 performance domains in modern versions.
- Aligns with PMP® certification; no direct guide certification.
Why Organizations Use It
- Boosts performance (3x likelihood in high-performers per PMI).
- Reduces risks via baselines, change control.
- Supports compliance in regulated sectors through traceability.
- Enables hybrid delivery, common language for stakeholders.
- Drives competitive edge, predictability, value realization.
Implementation Overview
- Phased: gap analysis, tailoring, pilots, rollout, improvement.
- Involves PMO setup, training, tools, change management.
- Scalable for all sizes/industries; geography-agnostic.
- Voluntary; internal audits/governance, no mandatory certification.
AS9110C Details
What It Is
AS9110C (AS9110:2016 Rev C) is an international certification standard for quality management systems (QMS) in aviation maintenance organizations, such as repair stations and MRO providers. It builds on ISO 9001:2015 with aerospace-specific requirements for continuing airworthiness, using a risk-based thinking approach across its 10-clause high-level structure.
Key Components
- Core pillars: context, leadership, planning, support, operation, evaluation, improvement.
- Aviation additions: configuration management, counterfeit parts prevention, human factors, traceability, external provider controls.
- Built on Annex SL framework; no fixed control count, but emphasizes documented information and process approach.
- Certification via accredited bodies with Stage 1/2 audits.
Why Organizations Use It
- Meets customer/OEM contracts and regulatory alignment (FAA/EASA).
- Mitigates safety risks, ensures traceability for airworthiness.
- Enhances market access via IAQG OASIS, improves on-time delivery.
- Builds stakeholder trust through proven QMS effectiveness.
Implementation Overview
- Phased: gap analysis, process design, training, audits (6-12 months typical).
- Applies to MROs globally, scalable by size.
- Requires internal audits, management reviews before certification.
