"Can I adjust my feature set and specifications as we go?"<p>Client: "Now, this TODO list app is great, but we want something more like Facebook and Linkedin combined"<p>This is exactly how you get feature creep and is a really bad idea for fix bid projects. But of course it depends on how big a pivot it is and how big a contract it is.<p>"Can I meet and work directly with the designers and developers on my project?"<p>Sure, you can meet and get advice from them, but you may not work directly with them. There are some pretty crazy clients out there, and it is the management's job to keep them from driving developers insane. That is why management gets the "big bucks". They have to deal with the crazy.
