The old strategy does not leave when the new one arrives.
Why it matters when the plan changes
A strategy is a decision and takes a day. An organisation is a pattern repeated through decisions, relationships, routines, systems and local interpretations, and it does not have a day. The lag is the interval where both logics are running, and where people absorb the difference by escalating, negotiating and working around. This is close to what Donald Sull, Rebecca Homkes and Charles Sull found in Harvard Business Review in 2015, where most managers polled did not believe their company's strategic priorities were fully resourced, a plausible sign of attention still pointed at the previous direction.
The tension is that the lag is not a failure of commitment. Priorities, decision rights, meetings, incentives and habits were all built to serve the previous direction and are working correctly. Treating the lag as resistance points the response at people. Treating it as an attention architecture points it at the five things that actually have to move.
In practice
A company shifts from regional to product-led growth in February. By June the strategy is well understood and the weekly forum still reviews regional numbers, the bonus still pays on regional targets, and the escalation path still runs through regional heads. Nobody is resisting. Everyone is following the architecture that is still in place.
Evidence
Stated priorities are widely believed to be under-resourced, which is what an organisation still pointed at the previous logic looks like from inside.

What it cannot tell you
The lag names the interval between a strategy changing and an organisation changing with it, but it does not diagnose which of the five layers, priorities, decision rights, meetings, incentives or habits, is holding attention in a particular case, nor how much deliberate work closing it will take.
How Atlas reads it
Attention is read across five places it accumulates: priorities, decision rights, meetings and information, incentives and measures, and relationships and habits. The lag is not treated as a fixed constraint. It is an architecture built over time, which means it can be seen, changed and tested, and the forecast says which part of it the plan most depends on moving.
Questions
Because a strategy is a decision and an organisation is a pattern, as Donald Sull, Rebecca Homkes and Charles Sull describe in their Harvard Business Review analysis, priorities, decision rights, meetings, incentives and habits were all built deliberately to serve what the company was doing before the decision changed.
No, and the difference decides the response. Resistance points at people and invites persuasion. The lag points at an architecture that is working exactly as designed for a direction that no longer applies, and it is answered by moving the architecture rather than the people.
As long as it takes for the five places attention accumulates to be moved, which is a matter of decisions rather than of time passing. Waiting rarely closes it, because each place stays where it is until someone with the mandate changes it deliberately.
From inside, it looks like conflicting priorities, escalation and misread performance. Donald Sull, Rebecca Homkes and Charles Sull found in 2015 that only 11% of managers believed their company's strategic priorities had the resources needed for success, a visible symptom of attention still pointed at the old direction.
Changing what the calendar and the measures point at. Meetings and incentives are the most visible carriers of the old logic and among the cheapest to change. Priorities and decision rights follow. Habits and relationships move last, and usually only after the others have.
