No we do not advocate abandoning your team but rather, leave your team to do their work without your interference.
Most leaders get to their position as a result of their great performance in previous positions. When you are the person having all the answers and doing great work, there needs to be a transition before you can lead a department or team.
Your team is recruited, selected, educated, trained and experienced to do their work. They should not need your constant involvement other than providing direction and guidance.
It is most demotivating for your team members when you move into the process of doing the work and start dealing with the issues directly. Certainly if you were the person previously doing the work yourself it may be difficult to let go of the work, you have done and leave it to others that may do things differently.
Getting the most out of your team happens when you leave them alone, however counter intuitive this may sound. Provide them with direction and guidance by setting the goals, tools and resources and get out of the way to see great things happen.
Monitoring the results is a key part of your role and you should have processes in place to ensure eventually the goals of the department/company get accomplished.
There is a delicate balancing act for you. Being involved enough in the work to be able to take responsibility for the work being done well is important. The other side of the scale is that you need to let go of being directly involved in the work and trust the processes and resources you put in place.
It is the equivalent of the coach, who is not supposed to personally enter the playing field but remain on the side and accomplish the results through the team he has recruited, selected, trained and encouraged. How are you doing this? What are your recommendations or tips?
