SUBDOMAIN 309.3 ? QUANTITATIVE ANALYSIS;Competency 309.3.2: PERT/CPM Techniques ? The graduate correctly applies PERT/CPM techniques;to project management tasks.;Objectives;309.3.2?01: Determine the critical path identified by a given PERT/CPM analysis.;309.3.2?02: Utilize PERT analysis to determine the probability that a given project will meet a specified;deadline for completion.;309.3.2?03: Determine slack time for a given project activity.;309.3.2?04: Determine scheduled start time for a given project activity.;309.3.2?05: Determine scheduled completion time for a given project activity.;309.3.2?06: Use time?cost trade?offs to appropriately crash a project network.;Introduction;This task requires candidates to prepare a program evaluation and review technique (PERT) chart and;apply critical path method (CPM) techniques.;Given;Company A is installing a Web?based customer?feedback system to meet customer needs for quick;response when rolling out new products. A new product line is rolling out in 48 weeks and the customer?;feedback system must be installed and running in time for the new product launch. Table 1.1 in the;attached Excel spreadsheet ?PERT/CPM Analysis Table? shows three estimates of the time it will take;Company A to complete each of the project activities in the customer feedback system project (optimistic;probable, pessimistic).Company B is installing a similar feedback system to accompany a new product;line and originally had the same time line as Company A.;Company B just announced that its new product line is ahead of schedule and will be launched in 44;weeks instead of the initially projected 48 weeks. Because the Web?based customer feedback system;must be installed and running in time for the revised date of the product launch, something must be done;to shorten implementation time required for the customer?feedback system project. Refer to Table 1.2 in;the attached Excel spreadsheet ?PERT/CPM Analysis Tables? that lists the expected time it will take to;complete the activities if shortened as much as possible (crash time), the cost to complete the activity;using normal resources (normal cost), and the cost of completing the activity on an accelerated basis;(crash cost).;Task;A. Use the estimates for Company A in Table 1.1 to do each of the following;1. Determine the expected completion time for each of the nine project activities.;a. Enter all your answers in Table 1.1, showing all of your work.;2. Determine the variance for each project activity;a. Entering all your answers in Table 1.1, showing all of your work.;3. Prepare a PERT chart showing the network diagram with activity times and their expected;durations.;a. Identify the critical path in the PERT chart.;Note: When the files opens, enter your name and student ID in the respective boxes so the;task questions and problems will populate the worksheet. If the attached template does not;open or is missing information, please contact Ecare for assistance with opening the file.;Note: Any additional numbers included in the PERT chart will not be evaluated for;correctness.;Note: If you don?t have software to build a PERT chart, use text boxes with lines or arrows in a;word processing program or a spreadsheet program.;4. Determine each of the following, showing all of your work or reasoning;a. Expected duration of the entire project;b. Slack for project Activity E;c. Slack for project Activity C;d. The earliest week project Activity F is scheduled to start;e. The latest week project Activity G is scheduled to finish;Note: Referencing a value in the PERT chart is not considered showing work. Please explain;how the value was determined.;5. Determine the probability of completing this project in time for the product launch in 48 weeks;showing all of your work.;Note: You may want to use the complete cumulative normal table located at;http://homes.cs.washington.edu/~jrl/normal_cdf.pdf;B. Use your results from part A1 and the data in Table 1.2 to determine the following;1. Maximum reduction in time;a. Enter your answer for part B1 in Table 1.2, showing all your work.;2. Crash cost per week;a. Enter your answer for part B2 in Table 1.2, showing all your work.;Note: For your responses to parts B1 and B2, assume that Company B has the same expected;completion times for project activities as Company A.;C. Identify the following by using your results from part B;1. Least costly activities to be crashed in order to complete the project within 44 weeks;2. Number of weeks each of the activities identified in part C1 should be crashed to meet the;deadline with the lowest possible increase in cost;3. Total additional cost due to crashing of the activities identified in part C1;D. When you use sources, include all in?text citations and references in APA format.;Note: To reduce unnecessary matches select ignore ?small matches <20 words? and ?bibliography.?;Note: For definitions of terms commonly used in the rubric, see the attached Rubric Terms.;Note: When using sources to support ideas and elements in a paper or project, the submission MUST;include APA formatted in?text citations with a corresponding reference list for any direct quotes or;paraphrasing. It is not necessary to list sources that were consulted if they have not been quoted or;paraphrased in the text of the paper or project.;Note: No more than a combined total of 30% of a submission can be directly quoted or closely;paraphrased from sources, even if cited correctly.
