What actually gets lost in a handover
Task lists usually survive because they exist on paper. What disappears is the context: that the second floor storeroom is excluded because a tenant keeps stock there, that the alarm has a delayed entry on the rear door, that the carpet in the meeting room was extracted three months ago, that the frequency was reduced last year to fund a day porter. None of that is exotic, and all of it changes how a new manager interprets what they are looking at.
The result is predictable. The incoming manager sees a schedule they did not design, notices something that looks wrong, and either escalates it or changes it. Sometimes that is healthy. More often it undoes a deliberate decision, and six months later the same problem the original arrangement solved reappears. A short record of why prevents most of that at almost no cost. Writing the reason next to the decision costs one line and saves a successor a season of guesswork.
