Phase 5
Sustained Access
Sustained Access measures whether the team can remain in position long enough to validate impact and collect evidence. The question is not whether access was possible once, but whether it can be kept without creating obvious noise.
Purpose
Some failures only appear over time: re-entry patterns, staff complacency, device exposure, weak response, or repeated reliance on trust. This phase captures that.
In Practice
That may mean staying on site, leaving and returning, retaining short-lived on-site access, or maintaining observation. If the evidence is collected and the risk is clear, the phase ends.
