Do you foresee any significant risk of a delay that the previous calculation does not take into account?

After signing the contract, the management at Midwest Parcel Distribution (MPD) discovers that for many reasons, it would be advantageous to complete the project in 40 weeks. It is too late for MPD to “require” the contractor, Iron Butterfly Company, to complete it in that time, but nonetheless, it discusses the possibility with Iron Butterfly’s project manager, Frank Wesley. Reviewing the network diagram (Figure 8.26), Frank checks the feasibility of this and then asks his managers and technical staff to give him three time estimates for every activity in the project; these are given in Table 8.7.
