Agree for very well specified projects where the amount of time a project will take can be easily be predicted and so a suitable fixed fee identified. In an ideal world all projects might look like that but in practice I think there's a chunk which don't. Agreeing fixed fees for these can be a horrible productivity killer because the estimates will tend to be way off and an "it's impossible to do this in the time/ budget allocated so why both trying" mindset can set in which de-motivates everyone working on it. In this environment I think fixed fee can encourage corner cutting so for me it's about taking projects on a case by case basis and deciding whether fixed fee or time and materials is appropriate based on how predictable the scope and workload will be.
