"Two things, was it something that needed to get done in the next 45 minutes? If not then a meeting is a big hammer for a small problem. If it only took 10 mins spread out over the course of several weeks it is still a time savings." Not true. There is an overhead to loading the relevant context into your brain each time you approach the issue. Looking at an issue 10 times over the course of a month is typically going to take much longer "person time" than blocking out the time to look through an issue all at once.
