Establish a governance model for introducing, changing, and retiring technologies

Overview

Without defined governance processes for technology lifecycle transitions, the portfolio grows in an uncontrolled way. Technologies are added without adequate review. Changes are made without assessing their impact on dependent applications. Technologies that should be retired persist because the process for removing them is unclear or the authority for doing so is contested. This chapter governs the decision-rights workflow itself; the separate chapter on defining entry criteria addresses what a technology must demonstrate to be approved, and the chapter on modernizing technologies deliberately addresses how to decide between upgrading, replacing, consolidating, or retiring a technology already in the portfolio.

Best Practice

Define and enforce a formal process for each type of technology lifecycle transition. Introducing a new technology requires a documented business justification, confirmation it meets the entry criteria already established for the portfolio, and documented approval by the appropriate governance authority. Making significant changes to an existing technology — a Strategic Disposition change, a major version upgrade, a new Rationalization Posture — requires impact assessment on dependent applications and governance approval at the level appropriate to the materiality of the change. Retiring a technology requires a transition plan that addresses every dependent application identified through Technology Spread analysis, data migration or destruction where applicable, and confirmation that all dependencies have been addressed before the technology is removed from the active Technologies Inventory.

Benefit(s)

Governed lifecycle transitions ensure that every change to the technology portfolio is intentional, reviewed, and communicated. New technologies enter the portfolio ready for operation rather than as undocumented additions that create immediate governance debt. Changes are validated before they affect dependent applications. Retirements are clean rather than disruptive, because every dependency was identified and addressed before the technology left the active inventory.
