I work for a small team right now that is going through a requirements tornado. I know that the reason why is that they have no idea what their users want. They haven't done contextual interviews, they don't have personas, user flows, or use cases, and we've done UAT but no usability testing. They hired me as a developer (even though I'm a UX person) and it's been hard to convince them that they've been going in the wrong direction.
Similarly, I was in a job interview for an internship last week and when they asked me what my goals for the internship were. I said a lot of HCI/UX stuff and the response was "We're in a fast-moving space and the most important thing to do is get there before the other guys, so we don't have time for user research."
Now, I know most of the facts/arguments that counter these statements/processes, but I've only been marginally successful in convincing people using them. What strategies do you use to get people to realize the benefits of solid user research?
