How a scope drifts without anybody deciding
Nobody sets out to change a cleaning arrangement informally. It happens because a request made in person at the right moment is very hard to refuse, and because each addition seems trivial compared with the whole. The cleaner accommodates it, it becomes routine, and something else quietly gives way to make room for it. Six months later the areas that were in the original scope are receiving less attention and nobody has connected the two.
The consequences show up at review. The committee sees a service that seems inconsistent with what it agreed, the contractor is working well beyond the priced scope, and neither party can reconstruct how the position arose. Both are worse off than if the first request had been recorded and put to the authorised contact for a decision at the time it was made. An arrangement that drifted quietly is very difficult to restore without somebody feeling accused.
