I believe this was a well intended effort to improve meeting productivity, but the proposed solution propagates tunnel vision and not helping teams keep the big picture of their design and development at the forefront of their approach. The assumption that 6 people in a 15 minute meeting = 90 wasted minutes vs a quick well written write up in 5 minutes is flawed. It doesn’t account for the time taken to read everyone’s updates. Nor the time to go back and re-read the updates as questions/clarification/conflicts come up an an update once you read them. If there is a status meeting that rarely results in some cross-team discussion on the status — then the content of the status is the issue, not the method it is delivered.
