Major policy changes are more achievable during institutional transitions than at any other time. The window is narrow and the preparation is everything.
Why Transitions Open Policy Windows
Policy change faces its greatest obstacle in institutional inertia — the accumulated weight of existing commitments, vested interests, established expectations, and cognitive anchoring that makes departing from the status quo costly even when the status quo is clearly suboptimal. This inertia is structural rather than volitional: it is not primarily produced by the preferences of powerful actors, though those preferences often reinforce it. It is produced by the coordination costs of changing what everyone has organised their behaviour around, and by the genuine uncertainty that every departure from established policy creates.
Institutional transitions reduce inertia by disrupting the coordination around existing policy. When the configuration that established and defended the existing policy changes, the expectation that the existing policy will persist changes with it. Actors who built their planning around the existing policy's continuation update their expectations. The organised interests that were invested in the prior policy's continuation face the uncertainty of whether the new configuration will share those interests. The cognitive anchoring that made departure from the prior policy feel risky is temporarily loosened by the transition's demonstration that the prior configuration's choices were contingent rather than necessary.
Window Duration and Closure
The policy window that transitions create is narrow. It closes as the new configuration establishes itself — as its own commitments accumulate, its own vested interests form, and its own version of the institutional inertia that blocked prior policy change begins to develop. The window is typically most open in the first months of the new configuration, before it has made enough commitments to constrain its freedom of action and before its own interests have converged with the status quo it initially had the mandate to change.
Policy initiatives that are ready when the window opens — that have been designed, costed, consulted, and prepared for implementation in advance of the transition — can move rapidly during the open window. Policy initiatives that use the open window to begin the design and consultation process will find the window closed before they are ready to advance. The preparation must precede the window, not follow it.
The policy window during a transition is the compressed moment when change that was impossible yesterday is possible today and will be impossible again soon. The question it asks is whether the initiative was ready before the window opened — because it will not wait for the initiative to get ready after.
