Technology strategy has a recognisable failure pattern: a well-argued document, broadly agreed, that changes very little. Not because the analysis was wrong — usually it is sound — but because it described a destination without changing any of the mechanisms that determine what the organisation actually does next quarter.
Those mechanisms are unglamorous: how work gets prioritised, who can decide what without escalation, how funding is allocated between change and run, and which team owns which capability. A strategy that does not alter these is a description of intent, and intent is not a plan.
