It's not just assigning work - it's assigning work that you as a manager are personally responsible for. The two benefits are reducing on workload and giving opportunity to grow to the person being delegated too.
If you’re only using delegation as a way of making your job easier, you’re missing the point. It’s not just about assigning work; there’s something in it for the direct, too. 1
For the person being delegated too, it's important that they also be delegated the power to make decisions related to the delegated work. Its also vital that others understand that you’ve delegated authority.
Potential for failure in delegation is actually a pro! It gives the opportunity to learn from mistakes. Don't wait until a report is "ready" for the work, but rather make failure a "safe option". Set them up for success, but allow room for failure, and don't jump in immediately when things start to go off track. 2
“Early on, my manager told me, ‘I don't want you to mess up. But if you mess up, I will have your back.’ This instilled in me that my manager trusted my decisions, was willing to help me through potential failure, and subtly applied pressure to live up to that trust. He said it once, but it was impactful enough that I still think about it when I face a new decision in my role,” says Madeline Willett, Associate Director for Division Operations at Verto Education. 3
“I trust you, make the call” might be the six most powerful words you can hear from a supervisor. 4
Ask someone if they want to be delegated the work, don't just tell. And explain to them why you've chosen them. If they say yes, you should then provide a brief and explain the intended outcome. In reality you should be delegating outcomes and letting the delegate decide the appropriate way to reach them.
