Project Network for a New Laptop Computer.

Task You are tasked with preparing a report detailing a project network for the senior management of this company and addressing specific questions that the management of the company has requested (see below). The method to employ will be critical path analysis (CPM). You are to present a report of no more than 500 words in length to the management board of the company detailing your network. Alternatively, you may present your results as a PowerPoint presentation with no more than 8 - 12 slides in total. The senior management of the company have questions which must be addressed in the report. These are listed below and "must be incorporated" into your report/presentation. Points that must be incorporated into your report: a) Management have requested you to prepare an appropriate AON (Activity on Node) network diagram for this project. You should draw the node for each activity as per the examples b) Management would like to know from your project network the critical path, the

Identification of Critical Path
 The red highlighted sections from Figure 1 are
identified as critical path activities within the project
 Scheduled duration of the project is calculated as:
= Sum of the total tasks in the critical path
= (90 + 25 + 14+ 20 + 45) days
= 194 days

Information on Project Network
 Management would need to complete the project 5
days prior than the scheduled period
 Crashing of the critical activities needs to be done
within 5 days

Information on Project Network
The critical activities are being listed in the following table:

J 45 149 194 149 194

Consideration of Management
Decisions
 Management needs the product launch 5 days prior
than the scheduled time
 An incentive structure has been planned accordingly
 Primary reason is competition with their global
competitor

The Project Crash Estimations
 The highlighted red activities are defined as critical
activities for the project
 The critical activities for the project are: A, F, G, D and J
 Lowest improvement factor is for activity G
 Next lowest improvement factor is for activity D
 Further lowest improvement factor is for activity F

The Project Crash Estimations
 Total reduction in the project duration is 7 days
 Duration of critical path after crashing is: 90 + 21 +
12 + 19 + 45 = 187 days
 Specific activities that needs to be crashed are: G, D
and F
 Capabilities of investment should help in deciding
over the early release of product
