Projects Build A A Done Build B B Done Build C C Done Build D Ship JAN FEB MAR APR MAY JUN On time! Unique, one-time operations designed to accomplish a specific set of objectives in a limited time frame.
5
Key Decisions 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
6
Project Manager Responsible for: Work Quality Human Resources Time
Communications Costs
7
Ethical Issues Temptation to understate costs Withhold information Misleading status reports Falsifying records Comprising workers’ safety Approving substandard work
8
Concept Project Life Cycle Feasibility Planning Execution Termination
Management
9
Risk: occurrence of events that have undesirable consequences
Project Risk Risk: occurrence of events that have undesirable consequences Delays Increased costs Inability to meet specifications Project termination
10
Risk Management Identify potential risks Analyze and assess risks Work to minimize occurrence of risk Establish contingency plans

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

Advantages of PM Software
Imposes a methodology Provides logical planning structure Enhances team communication Flag constraint violations Automatic report formats Multiple levels of reports Enables what-if scenarios Generates various chart types

Important activities may be omitted
Limitations of PERT Important activities may be omitted Precedence relationships may not be correct Estimates may include a fudge factor 1 2 3 4 5 6 142 weeks
