Establish an enterprise-wide TPM governance model

Overview

Without a defined governance model, TPM decisions are made inconsistently and without accountability. Different teams apply different standards to what belongs in the technology portfolio. Technologies are introduced without review, changed without oversight, and retained beyond their useful life because no clear authority exists to challenge or retire them.

Over time, this lack of governance produces predictable outcomes: duplicated technologies, rising costs, unmanaged risk, and increasing technology debt. Complexity does not accumulate through deliberate strategy — it accumulates through the absence of decision discipline. A TPM capability without governance is not operating as a program; it is reacting without control.

Best Practice

Establish a formal, enterprise-wide TPM governance model that defines decision rights, lifecycle control points, and enforcement mechanisms across the entire technology portfolio.

At a minimum, the governance model should clearly define which technologies are in scope for portfolio management; the required process for proposing, assessing, approving, operating, and retiring technologies; who holds decision authority at each stage of the technology lifecycle; how conflicts between business units or delivery teams are escalated and resolved; and how compliance with governance standards is monitored and enforced. Document this model as a formal TPM Governance Policy, published, communicated to all stakeholders, and reviewed regularly to ensure it remains aligned with organizational priorities and operating models. Limit the number of people with decision authority over each portfolio action — involving too many approvers slows decisions and creates bottlenecks.

Instead of creating new and separate meetings for TPM governance, weave it into existing Architecture Review Board (ARB) or Technology Review Board (TRB) meetings where they already exist. This lets TPM act as air-traffic-control for architecture and technology governance discussions, ensuring every decision is informed by current portfolio intelligence and every decision feeds back into the Technologies Inventory in near real time. It also makes technology portfolio conversations a normal, recurring part of the agenda rather than a special event.

Benefit(s)

A defined governance model with clear decision makers transforms TPM from a collection of isolated decisions into a disciplined, accountable enterprise capability. Portfolio changes are evaluated before they occur rather than rationalized after the fact. Technologies enter, evolve, and exit the portfolio through controlled processes aligned to business and technology strategy.

Decision-making becomes consistent because authority and process are clearly defined. Technology debt is actively managed rather than passively accumulated. Leadership gains confidence that the technology portfolio reflects intentional organizational choices, with known trade-offs, rather than the unintended consequences of ungoverned growth and deferred decisions.
