Zen Habits has a great post on doing less work. Not really doing less work per say but doing higher quality work by focusing on specific work rather than taking on everything (e.g. spreading yourself too thin).
At my old gig, we had a named all those worthless procedures and red tape. We called it non-valued added activities. The whole trick was to figure out what was just a waste of time and what really added value. We kept the value and eliminated the rest. I can see that doing less non-valued added work can free you up to do real work.
