Slack is a great read for those responsible for managing software teams and illustrates that there are no new ideas under the sun; there are just repackaged ones.
If you've read and liked Peopleware, you should read Slack as well. If you haven't read either one then you should.
I try to do the same. I've often viewed my job as trying to eliminate my job by slowly delegating and having others able to fulfill my current responsibilities. Then I take on the next "level" of responsibilities and/or provide either more slack in my schedule or others. Slack is what allows organizations to operate smoothly and deal with change(s).
If you aren't familiar with the concept of slack, I highly recommend reading "Slack: Getting Past Burnout, Busywork, and the Myth of Total Efficiency" by Tom DeMarco
