    2020

    U.S. standard protecting CUI in nonfederal systems.

    Quick Verdict

    PMBOK provides project governance principles for all industries, while NIST 800-171 mandates CUI cybersecurity controls for federal contractors. Companies adopt PMBOK for delivery success; NIST 800-171 for contract eligibility and compliance.

    PMBOK Details

    What It Is

    PMBOK® Guide, published by PMI, is a global standard and guide for project management. It codifies generally accepted practices for planning, executing, and governing projects across industries. Primary purpose: provide scalable frameworks for value delivery via process-based (earlier editions) or principle-based (7th/8th editions) approaches.

    Key Components

    • **Five Process GroupsInitiating, Planning, Executing, Monitoring/Controlling, Closing.
    • **Ten Knowledge AreasIntegration, Scope, Schedule, Cost, Quality, Resources, Communications, Risk, Procurement, Stakeholders.
    • ITTOs for ~49 processes; 12 principles and performance domains in modern editions.
    • Tailoring model; no formal certification but aligns with PMP.

    Why Organizations Use It

    Enhances predictability, reduces risks, ensures compliance via embedded controls. Drives strategic alignment, stakeholder trust, and high performance (3x better outcomes per PMI research). Voluntary but contractually advantageous.

    Implementation Overview

    Phased rollout: assess gaps, tailor processes, pilot, train, deploy tools/PMO. Applies universally; 12-24 months typical for enterprises.

    NIST 800-171 Details

    What It Is

    NIST SP 800-171 (Protecting Controlled Unclassified Information in Nonfederal Systems and Organizations) is a U.S. government cybersecurity framework providing recommended security requirements for safeguarding Controlled Unclassified Information (CUI) confidentiality in nonfederal systems. Its primary scope targets federal contractors and supply chains, using a control-based approach tailored from NIST SP 800-53 Moderate baseline, emphasizing risk-commensurate protections without full FISMA obligations.

    Key Components

    • 17 families in Rev. 3 (e.g., Access Control, Audit, Configuration Management, new additions like Supply Chain Risk Management).
    • ~97-110 requirements (Rev. 3 streamlines from Rev. 2's 110).
    • Built on FIPS 200 and SP 800-53; includes SSP and POA&M artifacts.
    • Compliance via self-assessment or third-party (e.g., CMMC Level 2), using SP 800-171A procedures.

    Why Organizations Use It

    • Mandatory for DoD via DFARS 252.204-7012; ensures contract eligibility.
    • Reduces breach risks, enhances resilience, builds stakeholder trust.
    • Competitive edge in federal procurement, supply chain positioning.

    Implementation Overview

    Phased: scoping CUI enclave, gap analysis, control deployment, evidence collection. Applies to contractors handling CUI; audits via SPRS/CMMC. Typical for mid-large orgs; 12-18 months.
