EXD.4:5.1 - Recover the concern before adding another explanation

An engineer explains that a proposed service reduces response time from eight minutes to five. A colleague replies: “You keep treating my objection as resistance to speed. I need somebody available throughout the night.” The comparison of response times does not answer that staffing concern.

Use the colleague’s stated correction: “You need continuous coverage; the five-minute figure applies only while an operator is present.” The explanation now exposes its condition. If coverage remains the question, return it to staffing and resource work; another account of the speed calculation will not supply an operator. If the colleague instead asks why the time falls to five minutes, provide that derivation under its stated conditions. The two continuations answer different contributions. Neither establishes agreement to deploy the service.
