Complaint-Driven Development
This is great for a startup but can be depressing for long term consulting.I've had the unfortunate experience of building a product for someone else where the process was driven by a combination of Complain-Driven Development and Upper-Management Wish-lists. This alone might have been fine but at the same time anything positive like the real analytics about how successful the product was or any non-complaint communication coming from the users was hidden from me for fear, I suppose, that I might try to use that information get my company more money.This became incredibly depressing. Everyday you show up to work putting in more and more hours into something that comes back with more and more complaints. It was hell and I did everything I could to end Complaint-Driven Development to no avail because thats how the customer liked to work.  Eventually I finally just gave up and left to find something more rewarding and less soul crushing.
