If the client doesn't trust you how will they ever agree to paying $x for an undefined
deliverable? Most clients want to know what they are getting for their money
so saying "well we're not really sure what exactly your going to get" just won't fly.
If you have the trust of your client the next requirement is that they understand
the software development process. They need to understand that things will go
wrong. Problems will arise. Adjustments will need to be made. If
they don't understand this they won't be very happy when features need to get cut
to fit in with the fixed price as well as the deadline.
I can't argue with you here. If your client doesn't trust you and won't bother to
learn about the software development methods you will use, then your project is doomed
to failure.
I remember hearing Maritn Fowler talk at an XP Denver meeting. When asked, "How
do you do fixed-price projects?," he answered, "We don't do fixed-price projects."
He then went on to explain that his most important job is in educating the customer
and establishing a level of trust so that they will understand the process. You have
to work with your customer to get them to see that a fixed-price, fixed-scope project
is a bad deal. There are only a couple of possible outcomes:
The project succeeds on time and under budget. The consultant makes money. Typically
this only happens when the consultant pads his estimate by at least a factor of 3.
Not a good deal for the client because they overpaid for their work.
The project runs long and goes over budget. The consultant is looking bankrupcy in
the face. They start pushing change orders at the customer. The customer gets pissed
and stops paying the bill. Everyone fights. Bad deal.
The project runs long and goes over budget. The customer understands and pays the
overage. Everyone is happy. Good deal, except that customers like this don't really
exist.
So the trick to doing agile projects is in educating your customer. You have to help
them understand that the only way to guarantee the success of the project is
by understanding the process and getting involved.
When the customer says, "My business is easy, just go build it," then you better run!
