What am I doing that no one should be doing? What am I doing that is a waste of time, contributes nothing to where we are going, and is useless, busy work? Eliminate it. And while at it test for system failures.
Of the work that is left that I do what can I delegate to others that by so doing the output per person on my team increases? Delegate it.
Note the order. Eliminate first. Delegate second.
Be ruthless with time spent on what doesn’t matter or is diminishing the work of others.
Examine time qualitatively first, then quantifiably second.
