Technology Portfolio Management (TPM) Best Practices

Overview

Technology debt remediation requires significant organizational investment: development capacity, testing resources, project management, and stakeholder coordination across every application and service affected by the indebted technology. That investment must be prioritized because it competes with new capability development, application rationalization, and other technology governance programs for the same organizational capacity. The priority criteria that produce the highest organizational return from technology debt remediation investment are portfolio-wide impact criteria — criteria that reflect the total organizational cost of the debt and the total organizational benefit of its elimination, not the urgency felt by any specific team or application owner.

Best Practice

Prioritize technology debt remediation using a portfolio-wide scoring model that weights the following factors. Adoption concentration: technologies with the highest number and the most business-critical set of dependent applications produce the greatest portfolio-wide benefit from remediation and should receive the highest priority relative to technologies with limited or low-criticality application dependencies. Debt severity: technologies whose current platform version is furthest from the current supported version, or that carry the most significant known security vulnerabilities, produce the greatest risk reduction benefit from remediation and should receive higher priority relative to technologies whose version currency gap is more modest. Annual debt cost: technologies with the highest current annual cost of debt operation produce the greatest immediate financial return from remediation and should receive higher priority relative to technologies whose annual debt cost is lower. Future cost acceleration: technologies whose remediation cost is growing most rapidly — because the gap between the current deployed version and the current supported version is widening as the vendor releases new major versions — should receive higher priority relative to technologies whose remediation cost trajectory is more stable.

Benefit(s)

Portfolio-wide impact prioritization of technology debt remediation produces investment decisions that maximize organizational benefit from the remediation capacity available. Teams that advocate for the remediation of technology debt affecting their specific applications — which is a legitimate and appropriate form of advocacy — can be heard within a governance framework that evaluates their advocacy against the portfolio-wide evidence rather than resolving priority purely on the basis of which team advocates most persistently or most forcefully. The organization’s remediation capacity is directed to the technology debt with the greatest organizational impact rather than to the debt that is most locally visible.
