Basically, you may be thinking, “Who says they are so critical to the project?” I do! And I'm pretty sure a lot of individuals who are deeply concerned with the success of the project they are leading or working on would say the same thing.
A good business analyst can make or break the project, in my opinion. I've one business analyst that the project customer liked so much that they paid an extra $100,000 in change orders just to have him work onsite at their location for the second half of the project even though the project was already running smoothly. Now that's customer security and satisfaction.
