> Assume the developer working here just had a 45 mins sync, has a meaningless repeat meeting about vapourware in 10 mins and a 2 hours town hall meeting after lunch... and still have to deliver that mess of a requirement you made him promise to deliver before any of these interruptions were even on his calendar!

If I have meetings loaded I am telling whoever is planning the sprint I am reducing my load for meetings. We, as software engineers, cannot allow this nonsense to continue. If I am interrupted 12 times a day I am bringing it up and the next sync. If it doesn't get fixed I am leaving. No one pays me to sit in meetings all day. If you want code delivered leave me alone or burn through young guns that don't know what they want yet.

While your post has a lot of good meat it is undermined by this single statement. It's far easier to work when you don't need to proactively reduce cognitive load to caveman levels because developers are by-and-large overworked.
