You're right.
Like you said, customers change their mind, either because they just do or because the business itself did, but things change despite its written on a 1000 sheet spec or not.
At the end of the day the customer wants it changed, even agreeing to pay for it, it's up to you to decide how hard it will be for you Smile | :) .

So what I think is that the software we write must be prepared to handle change in more way than just the user input, we also must prepare it for business change, for scalability, extensibility, etc...
Usually this doesn't mean a whole bunch of extra work, specially if it's design that way right from the beginning.

If the design is right you can start to think about software changes as a way of earning extra money instead of just loosing it! Shucks | :-\
