Do you really care about your clients? Are you an active listener? Can you put yourself in other people's shoes, consider what they want from you and respond?
You are chairing an important meeting in two weeks, and the agenda ought to go out today. Would you:
Not be aware of the forthcoming meeting until someone rings you?
Vaguely remember that it needs to be done, but keep putting it out of your mind, eventually faxing it on the day before the event?
Rely and act upon a regularly consulted diary system?
Do you live by the maxims 'Don't put off till tomorrow what you could do today' and 'Strike while the iron is hot'? Good project managers make things happen, immediately.
It has been said that project management is about three things: communication, communication, and communication. The project manager's skill is in communicating the right information to the right people at the right time, and ensuring that the project team does likewise.
Are you a good organiser? Can you organise your own time? Do you differentiate between what is important and what is urgent? Are you good at organising events and making them happen? Can you organise ideas and write a good brief? Can you structure a problem?
