Application Portfolio Management (APM) Best Practices

Overview

APM requires sustained investment in people, governance, data, and tooling. Without a compelling business case, that investment is difficult to secure and easy to cut when competing priorities emerge. The challenge is that the value of APM is often invisible until it is established - you do not know what you do not know about your portfolio until you have managed it well enough to find out. The business case must therefore be built on the cost of not knowing: the wasted spend that goes unidentified, the risks that go unmanaged, the decisions that go uninformed, and the transformation programs that stall because the portfolio is not understood well enough to change it deliberately.

Best Practice

Develop a formal business case for APM investment that quantifies the organizational cost of the current state where possible and estimates the value of the improved state. At minimum, the business case should address: an estimate of total application portfolio spend and the portion that is untracked or poorly governed; an assessment of known technical debt and end-of-life risk; examples of decisions that were made without adequate portfolio data and their organizational consequences; the expected investment required for the APM capability at each maturity stage; and the expected benefits in terms of cost reduction, risk reduction, decision quality improvement, and strategic agility. Use precise figures where available and orders of magnitude where precise figures are not yet obtainable.

Benefit(s)

A well-constructed business case secures the organizational commitment and sustained investment that APM requires to deliver results. Leaders who understand the cost of the current state and the value of the improved state become sponsors of the initiative rather than skeptics. The business case also establishes the success metrics against which the APM program will be evaluated, creating the accountability framework that drives rigorous execution and enables the program to demonstrate its ongoing value throughout its lifecycle.
