You are the engineer responsible for the design and installation of plumbing in a new public elementary school under construction. The project is running behind schedule ad above budget. The latest catch is that the supplier has not delivered the specified backflow preventers. Although a strike at the manufacturer's plant has been settled, the back order list is moving slowly. The engineer serving as coordinator of the project orders you to obtain less expensive backflow preventers that are readily available from another manufacturer. These backflow preventers are of lesser quality than those specified in the plans, have a history of occasional failure, and are likely to need earlier replacement. What should you do? O A. Order and install the available backflow preventers, but refuse to sign off on this portion of the job. O B. Order and install the available backflow preventers, informing the school board that this equipment may not last as long, but will help the project stay on schedule and closer to budget. O C. Wait for the specified backflow preventers and explain your action to the school board. O D. Order and install the available backflow preventers, and say nothing to the school board.

Caselet 2: You are an environmental engineer for one of the many local plants. That plant discharges effluents into a lake in a flourishing tourist area. Although all the plants are marginally profitable, they compete for the same customers. Your responsibilities are to monitor the water and air discharges at your plant and the periodic reporting to Dept. of Anti-pollution. You have just prepared a report that indicates that the level of pollution in the Plant’s water discharges slightly exceed the legal limits. Your supervisor says you should regard the excess as a mere ‘technicality’, and he asks you to ‘adjust’ the data so that the data appears to be in compliance. He says that slight excess is not going to endanger human or fish life any more than if the plant were actually in compliance. However he says, solving the problem would require a very heavy investment. He explains, “We can not afford new equipment. It might cost even a few jobs. It will set us behind our competitors.…
