    ISO/IEC 20000-1:2018 is the principal international certification standard for a service management system (SMS). It provides auditable requirements to plan, design, transition, deliver, and improve services across the full lifecycle, using a risk-based PDCA approach aligned with Annex SL for compatibility with other ISO standards.

    Key Components

    • Clauses 4–10: context, leadership, planning, support, operation, evaluation, improvement.
    • Clause 8 organizes operations into service portfolio, relationships/agreements, supply/demand, design/transition, resolution/fulfilment, assurance.
    • Core processes include incident/problem management, change/release, configuration, availability/continuity/security.
    • Certifiable via independent audits.

    Why Organizations Use It

    • Builds trust, reduces risks (44% report lower business risks), improves services (59%).
    • Enables market differentiation, tender wins; 50% global certificate growth.
    • Integrates with ISO 9001, 27001 for unified governance.
    • Ensures measurable reliability in multi-supplier ecosystems.

    Implementation Overview

    • Phased: gap analysis, SMS design, deployment, audits (typically 12-18 months).
    • Applies to all sizes/industries; flexible with ITIL/DevOps.
    • Stage 1/2 certification audits, surveillance/recertification required.

    SOX Details

    What It Is

    Sarbanes-Oxley Act of 2002 (SOX) is a U.S. federal regulation enacted post-Enron scandals.

SOX employs a risk-based, control-oriented approach via SEC rules and PCAOB standards.

    Key Components

    • Three pillars: PCAOB oversight (Title I), auditor independence (Title II), executive certifications and ICFR (Titles III-IV).
    • Key sections: §302 (CEO/CFO certifications), §404 (ICFR assessment/attestation), §409 (real-time disclosures).
    • Built on COSO framework; no fixed control count, focuses on key controls.
    • Compliance via annual management reports and auditor opinions.

    Why Organizations Use It

    • Legal mandate for U.S. public companies; protects investors, reduces fraud.
    • Enhances governance, operational efficiency, investor trust.
    • Lowers cost of capital, aids M&A/IPO readiness.

    Implementation Overview

    • Phased: scoping, design, testing, monitoring using top-down risk approach.
    • Applies to public issuers; scaled for size (exemptions for smaller filers).
    • Requires annual audits, continuous monitoring; no formal certification but SEC/PCAOB enforcement.
