THE BRICK WALL CASE STUDY 9.1 while addressing this case study. It is now the end of day 3, the day of rain that caused the effort to fall 13 now time to reexamine the brick wall example from this chapter. That example must be referred to Dahind schedule and to indicate cost overrun. Decisions must be made as to whether to accelerate the project to ensure that it finishes on schedule or possible to intentionally delay it to try to recover some of the cost overrun by using only the most efficient workers. The key to this decision will be accurate recasts of what the cost and schedule will be for each of these scenarios. In other words, an Estimate Completion (EAC) must be developed for each case. Your assignment then is to generate an EAC for sach alternative (actually a pair of "what if?" scenarios) based on the following information: To finish on day 4, the remaining work may need to be done on overtime. The pay rate for overtire is time and a half, i.e. 50% higher than for straight time. Choosing this alternative would be appropriate if this is a schedule critical project (.e. It is imperative that the project finish on time, even if costs increase as a result). Case B Consider the alternative of delaying completion of the project to day 6. Because of the cost overrun to date, a decision could be made to stretch the completion while using only the most efficient workers. Our assumption is that elimination of the two least productive work- ers will improve productivity by 15%. Choosing this alternative would make more sense if this is a cost critical project (i.e. cost impact is more important even if it means a schedule delay). Case A 1. What is the most likely EAC if no corrective action were implemented? 2. Develop an EAC for Case A. 3. Develop an EAC for Case B. Note : It is important to evaluate what future performance is likely to be when developing an EAC. Thus the circumstances that produced the current conditions must be considered in determination of projecte final costs.
