Answer each question in 1 paragraph.

1. For many routine maintenance replacement items, a hotel manager has a choice between doing all of the maintenance at once (such as changing air filters in all guest rooms quarterly) and doing it as needed (such as replacing hot water heater pumps when they stop working). In other cases, such as replacing parking lot light bulbs or fan belts on motors, the manager has a choice between systematic total replacement and a replace as needed approach. Assume that you were required to decide on a replacement program for exterior parking lot lights in a hotel with parking for 150 cars. What factors would influence your decision?

2. Maintaining food service equipment often requires specialized skill and replacement parts. Name three factors that you would consider before deciding to outsource the preventive maintenance of such equipment rather than performing it in house.
