The Shared Contingency Idea

Essentially, any of these solutions might be called shared contingency (my term). In the Goldratt approach, it is applied in several stages. First, he locates the critical path and reduces task durations to be consistent with a 50 percent probability rather than 90 percent. Half of the removed duration is added at the end of the path, as a project buffer. Next, the feeder paths are located and treated in a similar manner, and half of the removed duration is added at the end of each feeder path,...
