2. Anita, Senior manager Marketing Communication of ABC Company, was assigned the task of organizing and training five teams of sales executives about a new product the company has recently launched. Two types of materials must also be prepared: (1) those for use in training the executives and (2) those for distribution later. Trainers must be brought in and arrangements made for transportation and accommodations for the participants. Anita first called a meeting of her office staff Together they identified the activities that must be carried out, their necessary sequences, and the time that they would require. Their results are displayed in Table 1. One of the staffs noted that the project had to be completed in 60 days. "An impossible task, then," he noted. "No," Anita replied, "some of these tasks can go forward in parallel". "There aren't that many of us to go around. There are only 10 of us in this office", the staff member worried. "I can check whether we have enough heads and hands once I have tentatively scheduled the activities," Anita responded. "If the schedule is too tight, I have permission from the Director to spend some funds to speed it up, just so long as I can prove that it can be done at the least cost necessary. Can you help me prove that? Here are the costs for the activities with the elapsed time that we planned and the costs and times if we shorten them to an absolute minimum "Those data are given in Table 2. Questions: (i) Some of the tasks in this project can be done in parallel. Prepare a diagram showing the required network of tasks, and define the critical path. What is the length of the project without crashing? Page 2 of 7 (ii) If the critical path is longer than 60 days, what is the least amount that Anita can spend and still achieve this schedule objective? How can she prove to the Director that this is the minimum-cost altemative? Table 1 Table 2
