I wonder how this works when you need input from a coworker whose number one focus is different than your own. If this coworker, in turn, is reliant on input from you for something that is not your number one focus then you are deadlocked...each waiting for the other to finish but unable to finish until the other has time.
Easy, escalate to a boss who's only focus is making sure you both get your work done. I'm also sure trades and bribes and a informal form of corporate currency changes hands
"I'll purposefully and intentionally reduce my focus from 100% to 99.999% this year by helping you out IF in exchange you'll do something that improves my efficiency in my remaining 99.999% of the time by around a factor of one ten-thousandth"
Its a market driven approach. Plenty of game theory behind it, too.
