“Only do what only you can do.”
Only do what only you can do. Otherwise delegate, until there is no-one else to delegate to.
An boss of mine years ago banged this into my head, and it’s still there, and it’s still key to making my life sustainable and my company profitable.
I often seeing my own direct reports doing things that their teams could do. Meanwhile, I see their staff on facebook or chatting at their desks. I repeat like a mantra, “Only do what only you can do.” If anyone who works for you can do the task you are currently doing, stop immediately and delegate. If there is a shared-service function that can do what you are currently doing, stop and delegate. If, once you take into account the fixed-cost of delegation, you save one single minute by delegation, you should delegate.
Delegation should go as far down the company as possible, right up until the point where quality would suffer and no further. As a leader, ensuring this happens is your responsibility to whoever is paying your bills. To do otherwise is to do your shareholders a disservice.
Think through the activities involved in your most recent hour of work. Was there anyone else who could have done it?
