ISO Survival Kit: 100 Common Audit Failures in ISO/IEC 20000:2011 IT Service Management Systems

1. Clause 4.1 – Management Responsibility Lacking Depth

What’s Going Wrong: Top management is not actively engaged in reviewing or supporting ITSM efforts. Strategic alignment between business and IT is vague or missing entirely.

Why It Matters During an Audit: Auditors expect to see management reviews, documented decisions, and evidence that leadership is driving service management initiatives.

How to Fix It: 

✔ Establish a regular management review cycle focused on ITSM objectives and performance. ✔ Record and act on leadership decisions during these reviews. 

✔ Include ITSM in executive KPIs and integrate it into broader business governance.

Real-World Result: Improves oversight and creates executive-level accountability, ensuring service management is prioritized at the top.

2. Clause 4.2 – Incomplete or Weak Service Management Policy

What’s Going Wrong: The organization’s ITSM policy is generic, lacks specific goals, and doesn’t reflect business priorities or the scope of service management.

Why It Matters During an Audit: A weak policy signals a lack of direction. Auditors expect a tailored, communicated, and reviewed policy that aligns ITSM with organizational goals.

How to Fix It: 

✔ Define measurable ITSM goals within the policy. 

✔ Clearly describe the scope and commitment to continual improvement. 

✔ Publish the policy internally and review it at least annually.

Real-World Result: A clear, measurable policy provides focus for teams and impresses auditors with its strategic alignment.

3. Clause 4.3 – Unclear Roles and Responsibilities

What’s Going Wrong: Staff are unclear on who owns which ITSM processes, leading to overlaps, gaps, or slow decision-making.

Why It Matters During an Audit: Role confusion means poor accountability and a higher risk of service failure. Auditors look for structured delegation and defined ownership.

How to Fix It: 

✔ Use a RACI matrix to map responsibilities across all ITSM processes. 

✔ Align job descriptions and training with assigned roles. 

✔ Communicate these roles in onboarding and periodic team reviews.

Real-World Result: Improved coordination across departments, faster responses to incidents, and stronger audit performance.

4. Clause 4.5 – Document Control Deficiencies

What’s Going Wrong: Teams use outdated or uncontrolled documents; version control is non-existent or manual.

Why It Matters During an Audit: ISO/IEC 20000 requires that all ITSM documentation is current, authorized, and reviewed. Uncontrolled documents create confusion and audit risk.

How to Fix It: 

✔ Implement digital document control with access rights and versioning. 

✔ Define a document lifecycle: creation, review, approval, and retirement. 

✔ Train users on how to locate and use approved versions.

Real-World Result: Reliable documentation supports daily operations and builds confidence during audit walkthroughs.

5. Clause 5.1 – Absence of Defined Service Delivery Plans

What’s Going Wrong: Services are provided without formal service design or documented delivery methods. SLAs are vague or not enforced.

Why It Matters During an Audit: Auditors need proof that services are consistently delivered, managed, and monitored against defined performance criteria.

How to Fix It: 

✔ Develop detailed delivery plans for key services.

✔ Include agreed SLAs, performance metrics, and dependencies. 

✔ Regularly review and update the plans based on feedback and metrics.

Real-World Result: Predictable service quality and reduced customer complaints; improved audit readiness and service transparency.
