A Kaohsiung clinic group ran a Thursday operations hour that routinely crossed ninety minutes because every department retold the week. The director believed courtesy required it. Patients in the waiting area did not share that theory.
In the Review Chair Workshop we placed a cheap kitchen timer next to the agenda. When a story outran its slot, the chair said “park” and wrote a name. Parks that never returned were deleted from next week’s panel. Parks that returned twice became tiles with stewards.
People called the timer cold. It was. Courtesy that steals the next decision is not kindness to the organisation. It is kindness to the speaker.
Ending on time is a performance metric of the meeting itself. If you will not measure the hour, do not pretend you measure anything else inside it.
