A design engineer is responsible for an important sub element of a large project at a firm. The project has fallen behind schedule, and the important client is very angry and threatening to sue. The boss is expecting the engineer’s design review to go well so that the project can be shipped by the end of the week. The engineer notices during final design review that an element of the design is wrong and will create a major safety issue for the entire system. To rework that portion of the design will take several months. The engineer should do which of the following?   

A. Sign off on the drawings because of the threatened lawsuit and because the project is so far behind.

B. Do not sign off on the drawings, and let the boss know what is found at the final design review.

C. Tell the boss that to sign off on the design now, the engineer must have an immediate raise.

D. Sign off and keep on how construction goes. Maybe the engineer can correct the safety issues before the project is fully operational.
