Application Portfolio Management
Application portfolio management (APM) is the discipline of inventorying, evaluating, and rationalising an organisation's entire application estate — making deliberate decisions about which applications to retain, invest in, migrate, or retire based on business value, technical health, and total cost of ownership.
How it works
APM begins with discovery: cataloguing every application in use, its vendor, version, users, integrations, and annual cost. Each application is then scored against two axes — business value and technical fit — typically in a TIME model (Tolerate, Invest, Migrate, Eliminate). The portfolio view reveals duplication, shadow IT, and applications past their useful life. Rationalisation decisions are phased over a 3–5 year roadmap.
Selection criteria
| Criterion | What to evaluate |
|---|---|
| Discovery coverage | The APM tool or process needs to surface shadow IT, not just sanctioned applications. Integrating with IT asset management and SaaS spend management tools increases discovery coverage. |
| Scoring methodology | Define the business value and technical health dimensions before scoring. Inconsistent scoring criteria produce an unreliable portfolio view. |
| Integration dependency mapping | An application cannot be retired without understanding what depends on it. APM tooling should map integration flows, not just application metadata. |
| Cost consolidation | TCO should include licence fees, infrastructure costs, support costs, and internal IT time. Applications that look cheap on licence fees often have high support costs. |
| Governance cadence | A portfolio view that is not refreshed quarterly becomes a historical artefact, not a management tool. |
