    PMBOK Details

    What It Is

    PMBOK® Guide, published by the Project Management Institute (PMI), is a global standard and guide for project management practices. It provides a framework for planning, executing, and governing projects across industries, evolving from process-based (6th edition) to principle- and performance domain-based (7th edition) with emphasis on tailoring to context.

    Key Components

    • 5 Process Groups: Initiating, Planning, Executing, Monitoring/Controlling, Closing.
    • 10 Knowledge Areas: Integration, Scope, Schedule, Cost, Quality, Resources, Communications, Risk, Procurement, Stakeholders.
    • 12 Principles and performance domains (e.g., governance, risk); ITTOs for processes.
    • No formal certification for the standard; aligns with PMP® credentialing.

    Why Organizations Use It

    Enhances predictability, reduces risks via baselines/change control; supports compliance in regulated sectors; drives value delivery and high performance (3x more likely per PMI research); builds stakeholder trust and competitive edge through standardization.

    Implementation Overview

    Phased rollout: assess gaps, tailor processes, train/certify staff, pilot, deploy PMO/tools. Applies to all sizes/industries; voluntary but contractual in some cases; focuses on maturity via organizational maturity models.

    ISO 28000 Details

    What It Is

    ISO 28000:2022 is an international standard specifying requirements for a security management system (SMS) focused on supply chain security. It provides a risk-based framework using the Plan-Do-Check-Act (PDCA) cycle to manage threats like theft, sabotage, and disruptions.

    Key Components

    • Clauses 4-10 cover context, leadership, planning, support, operation, evaluation, and improvement.
    • Emphasizes risk assessment aligned with ISO 31000, operational controls, and security plans.
    • Built on harmonized ISO structure for integration; supports certification per ISO 28003.

    Why Organizations Use It

    • Reduces supply chain risks and incidents.
    • Meets contractual, regulatory, and insurance needs.
    • Enhances resilience, market access, and partner trust.
    • Provides governance for third-party risks.

    Implementation Overview

    • Phased approach: gap analysis, risk assessment, controls, training, audits.
    • Applicable to all sizes/industries; 6-36 months typical.
    • Involves internal audits, management reviews, optional third-party certification.
