A client hired me to research and develop a signal processing algorithm which would eventually be used in a final product.
A couple of months in, I realise that the client's specifications are almost impossible to achieve. I put together a document detailing why, but the client continues to insist on paying for myself and a team of people to continue to research this particular idea.
It's been getting to the point where myself and the team I manage are becoming very discouraged because we all can see that this isn't going to work.
I really want to fire this client, but he is relying on me to manage his team and lead this project, so he's not going to be very happy with me at all. He's absolutely convinced that this is the Best Idea Ever. How do I get myself out of this without ruining my oDesk rating?
