1. You were hired by a small business as the project manager of a project involving a market analysis. This project will determine whether the company goes ahead with the large scale manufacturing of a brand new product. The activities of the project are described below, with their respective durations: ID Duration (weeks) Predecessor a) Draw a project network with this information. Complete the forward and backward pass, compute activities slacks, total project duration, and identify the critical path. All activities presented previously require 2 full time analysts, except for activity F that requires only two analysts. You originally had in mind to include three analysts as part of your team but one of them just accepted a job from another company (leaving you with only two available analysts). A 2 None B 1 A C 3 A D 1 A, B E 2 D F 3 D G 2 E H 2 G, F b) Develop a resource constrain schedule in a resource loading chart. c) Using the resource load chart, record the order in which you schedule the activities using the following scheduling heuristics: 1) minimum slack, 2) smallest duration, lowest ID. d) Determine the new project duration. Remember to update the ES, LF and SL 2. The company just informed you that a competitor may have been working on a similar product. They have asked you to crash the project. The associated indirect costs based on the projects duration are: $11,000 for 12 weeks, $8,000 for 11 weeks, $4,500 for 10 weeks, $4,000 for 9 weeks, and $3,500 for 8 weeks. The following table summarizes the cost of crashing your project by activity. a) Use the least cost method and reduce the schedule until you reach the crash point of the network. For each move, identify what activity(s) was(were) crashed, the adjusted total cost, and explain your choices. b) What is the optimum cost-time schedule for the project? What is the cost? c) c) Draw the Cost-Duration Graph in graphing grid below or in MS Excel. Normal ID Crash Cost Max. crash time Time Cost A 0 0 2 4,000 B 0 0 1 1,500 C 2,000 1 3 6,000 D 0 0 1 3,000 E 2,500 1 2 8,000 F 5,000 1 3 12,000 G 3,000 1 2 5,000 H 4,000 1 2 1,500 Total 41,000
