But project managers often do the work they like and are familiar with, rather than work that needs to be done. Even if it's work that contributes to a project's overall success, I find that many of us focus on tasks that we're familiar with or that we already know we're good at.
Regardless of how great I am with some tasks, I know that I must fill in my own knowledge gaps with team members' expertise. Because in addition to being a good project manager, the real trick to getting things done is surrounding myself with a capable, well-trained project team.
Instead of trying to learn everything and being everything to everyone, I accept that I won't always know it all. I ask for input from the team on a regular basis. This makes the team feel needed and appreciated for their contributions and makes the project execution more efficient.
Do you tackle the tasks you're good at rather than those that need to get done? How do you balance your own expertise with that of your team members?
