Changing Quality

Another option for accelerating the schedule is the changing of the quality specifications of the product. This is usually done as a scope change.

Making Up Time by Reducing Quality

At a midwestern university, a new building was being built, but it was behind schedule. To speed up the installation of the heating and cooling equipment, it was decided to make the zones of control larger, which meant that each floor would have fewer points where temperature was sensed and controlled and fewer air flow control boxes. The contract did not specify the zone size or how many control points were required on each floor of the building, so this change did not require a change in scope. As a result, when the sun is coming in on the south side of the building, those rooms get as much heat or cooling as the rooms on the north side, so they are often too hot. If the single temperature controller on each floor is set to a lower temperature, the rooms on the north side are too cold. The client for the building did not realize this change had been made until they were in the building for several months and the project was completed.
