After months of analysis and expert commentary, our 10-part series on IBM license compliance audits comes to a close.

Across each instalment, we’ve explored how to take control of every stage, from audit notification to settlement, turning what many view as a vendor risk into an opportunity for governance and cost optimisation.

Here are the 10 most important lessons that can transform how your organisation approaches IBM compliance.

1. Preparation sets the tone

Every successful audit starts long before IBM contacts you. Knowing your entitlements, maintaining accurate inventories, and mapping your compliance position gives you control before the process begins.

2. Sub-capacity compliance is non-negotiable

For processor-based metrics, ILMT (or an approved equivalent) is essential. Missed reports or outdated versions can turn discounted sub-capacity licensing into full-capacity penalties.

3. Protect your data with an NDA

Before sharing any information, safeguard your organisation with a Non-Disclosure Agreement. It limits exposure, ensures confidentiality, and reinforces internal governance standards.

4. Define the audit before it defines you

Negotiating audit scope, timelines, and data collection methods prevents overreach and ensures the process stays focused, efficient, and fair.

5. One voice avoids many mistakes

A central contact person ensures consistent communication and validated data. One voice prevents confusion, conflicting messages, and duplicated effort.

6. Not every data request deserves a yes

IBM auditors may ask more than they need. Understand why each question is being asked, provide relevant context, and challenge unclear or unnecessary requests.

7. Always review the draft ELP

The draft Effective License Position (ELP) is where assumptions become numbers. Review every line carefully, verify calculations, and document your reasoning before IBM sees it.

8. Explore alternatives before accepting findings

Cloud Paks, user-based metrics, and non-production licenses can all reduce settlement costs. Knowledge of these options is your strongest negotiation tool.

9. Follow up or fall back into risk

Settlement isn’t the end of compliance. Implement agreed changes, fix sub-capacity reporting, and clean up inactive user accounts to prevent repeat findings.

10. Document everything

The most overlooked step is also the most powerful. Record every data source, contact, and methodology. Strong documentation turns experience into strategy and accelerates future audits.

Final Thoughts

IBM audits don’t have to be chaotic or reactive.
When approached methodically, with preparation, documentation, and informed challenge, they can become a predictable, controlled, and even strategic exercise.

At ITAA, we help organisations build that confidence by transforming audit lessons into continuous compliance improvement.
