Depends. If you’re the team’s bottleneck/constraint, avoid interruptions at all costs. If you’re not, you’re a potential blocker for the bottleneck - in which case you want to be as interruptable (by the bottleneck) as possible. https://twitter.com/MikeIsaac/status/1042497174028705793 …

The reason for this comes from manufacturing. If a bottleneck machine is sitting idle, the cost of it being idle is the *burn rate of the entire system.* So, 1 min of distracting bottleneck is 1 min of entire team’s burn - as is 1 min of bottleneck waiting for answer.
