This is an article from David Allen and Justin Hale, on 7 Ways Managers Can Help Their Team Focus. For most it's more than a two-minute read, and closer to five, in case you are deciding whether to do it now or add it to a list.
I was so very glad to see this! As everyone knows, I am a strong advocate for time blocking for projects, areas of focus, or just to sit with a paper pad and think. We must protect our time so we can do deep work. Cheers David and Justin!
