AudioBoo: Setting up a successful PMO http://boo.fm/b56566
A project manager who is joining an existing team needs to asses te new environment before implementing best practices.
The environment will dictate how beat practices should be implemented. For example, if the environment is not mature, meanig they are new to using project management best practices, then a successful project manager will need to weight how much is too much information and process. Typically a less mature environment will resist processes and procedures that are too complicated. So, for example, expecting people to provide cost index metriced on status reports would be ove their head. It would be like feeding a baby a full course meal rather than spoon feeding them baby food.
