We cannot totally predict what will happen during a project but we can be prepared for those eventuallities.
How would you handle the following:
What happens to the project if a Star gets hit by a bus (becomes incapable of work)?
What happens if you lose funding or the company is sold/bought?
What happens if the "shared" repository/directory is deleted?
What happens if you get replaced?
What happens if the project priorities get changed?
What happens if you realize that you cannot complete the project on time, on budget, with the staff you have?
What happens if everyone (or their kids) gets sick? for a week?
What happens if the project Sponsor quits?
What happens if another project becomes the priority?
What happens if your political rival gets promoted and inherits your project?
What happens if someone offers you a better position with double the pay?
There is no right answer, except that you must prepare a list and have an answer to each of the questions on your list.
