Abstract
This chapter presents a comprehensive strategy for auditing IT application portfolios to mitigate risks, enhance governance, and drive strategic optimization. Targeted at IT auditors, risk professionals, and enterprise architects, it integrates frameworks such as CISA, COBIT, ITIL, SOC 2, NIST, and ISO 27001 to guide practices in inventory validation, business alignment, cost-effectiveness, technical risk, and cloud readiness. Structured tools like checklists, the TIME model, and dashboards support a systematic audit process. A hypothetical case study illustrates practical application across multi-industry and multi-region settings, demonstrating how audit-driven insights can uncover redundancies, improve lifecycle health, and strengthen operational resilience. This chapter per the authors emphasizes that a well-governed application portfolio audit not only ensures compliance and risk mitigation but also enables substantial cost savings and better alignment with modernization goals.
