You work for a consulting company that has been hired to do the systems design portion of the project. The systems analysis portion was done by another consulting company. During systems design, you find what you are definitely sure is a mistake in the requirements. You are not sure just how serious it is, but you know this for sure: if this mistake, made by another company, is pointed out to the project manager, systems design work will have to be halted until the mistake is fixed. This will put your company behind schedule and either it will have to pay you and its other consultants for sitting around while the mistake is being fixed, or it will lay all of you off.

What is your ethical obligation in this situation?
