Application Portfolio Management (APM) Best Practices

Overview

The Applications Inventory is the spine of APM - every application record is the anchor point to which all other portfolio data connects. But an application record in isolation is a thin and incomplete picture of the application it represents. It tells you what exists. It does not tell you what it fully costs, what it depends on, what risks it carries, what contracts govern it, how much technical debt it carries, or what breaks if it changes. The analytical power of APM comes not from the Applications Inventory alone but from the connections between it and the other governed inventories that surround and enrich it.

Best Practice

Design the Applications Inventory as the central node in a connected portfolio data model, and invest in building and maintaining the connections between it and the

Benefit(s)

An Applications Inventory connected to the full ecosystem of supporting enterprise inventories transforms portfolio analysis from a narrow examination of application attributes into a rich, multi-dimensional assessment of each application’s full organizational footprint. Cost analysis is complete rather than partial. Risk assessment is comprehensive rather than limited to what is visible in the application record itself. Impact analysis is actionable because the dependencies that would be affected by any portfolio decision are visible, governed, and quantified.
