Finally, every project creates a unique product or service. This is the deliverable for the project and the reason that the project was undertaken. A refinery that produces gasoline does not produce a unique product. The whole idea, in this case, is to produce a standardized commodity; you typically don’t want to buy gas from one station that is significantly different from gas at another station. On the other hand, commercial airplanes are unique products. Although all Boeing 777 airplanes might look the same to most of us, each is, in fact, highly customized for the needs of its purchaser.
