Don’t treat your project team with favouritism. Be fair and even with all your project team.
Use job performance related metrics rather than personal preferences when allocating roles, tasks and rewards
Good, regular project status reports are a very important way to ensure you and your projects are noticed. If you regularly make project status reports for all your projects, you will get noticed and be more likely to keep your job and get promoted.
Projects often fail because the project team members are not clear on their roles and responsibilities. Make sure your project team members know what they are supposed to do with defined roles, clear role descriptions and briefs of what they should be doing.
