PROJECT MANAGEMENT PART SIX Chapter Eighteen Project Management
2
Unique, one-time operations designed to accomplish a specific set of objectives in a limited time frame. Build A A Done Build B B Done Build C C Done Build D Ship JANFEBMARAPRMAYJUN On time! Projects
3
Deciding which projects to implement Selecting a project manager Selecting a project team Planning and designing the project Managing and controlling project resources Deciding if and when a project should be terminated Key Decisions
4
Project Manager Responsible for: WorkQuality Human ResourcesTime CommunicationsCosts
5
Temptation to understate costs Withhold information Misleading status reports Falsifying records Comprising workers’ safety Approving substandard work Ethical Issues
6
Project Life Cycle Concept Feasibility Planning Execution Termination Management
7
Risk: occurrence of events that have undesirable consequences –Delays –Increased costs –Inability to meet specifications –Project termination Project Risk
8
Identify potential risks Analyze and assess risks Work to minimize occurrence of risk Establish contingency plans Risk Management

PERT and CPM PERT: Program Evaluation and Review Technique CPM: Critical Path Method Graphically displays project activities Estimates how long the project will take Indicates most critical activities Show where delays will not affect project

A project consists of 10 activities, lettered A through J, as shown in the accompanying precedence diagram, with the activities on the arrows. For each activity, the deterministic time estimate in weeks is shown in the following table. Activity Time Activity Time ABCDE 24356 FGHIJ 34431 List all of the paths through the network. What is the duration of each of the paths? What is the critical path? What is the second-most critical path? What is the slack time for each activity? Calculate the ES, Ef, LS and LF times for each activity. Advantages of PM Software

Advantages of PERT Forces managers to organize Provides graphic display of activities Identifies –Critical activities –Slack activities 1 2 3 4 56
28
Limitations of PERT Important activities may be omitted Precedence relationships may not be correct Estimates may include a fudge factor 1 2 3 4 56 142 weeks
