1 Opermgt 345 Shannon January, Project Management Basic Concepts Opermgt 345 January, 2001

2 Opermgt 345 Shannon January, What is a Project? A Project is a series of activities and tasks that: Have a specific objective to be completed with certain objectives Have a defined start and end dates Have funding limits (if applicable) Consume Resources

3 Opermgt 345 Shannon January, Typical Project Structure Project Definition Project Definition Project Planning Project Planning Project Implementation Project Implementation Project Monitoring Project Monitoring Project Adjustment Project Adjustment Project Evaluation Project Evaluation

4 Opermgt 345 Shannon January, Project Life Cycle Resources and Effort Phase 1 Goals Scope Baseline Requirements Feasibility Desirability Conceptual Design Phase 2 Advanced Development Plan Budget Schedule Management Commitment Phase 3 Detailed Design Define Responsibility Team Organization Structure Detailed Plan Kickoff Phase 4 Project Implementation Manage Measure Control Update and Modify Plan Problem Solve Project Termination Phase 5 Closeout Document Suggest Improvements Reassign Dissolve Project Team

5 Opermgt 345 Shannon January, Successful Projects A successful project is one which achieves the following objectives: –Completed On Time –Completed Within Cost –Meets Performance Criteria –Minimum Disruption of the Main Work of the Organization –Effective Utilization of Resources

6 Opermgt 345 Shannon January, The Triple Play of Project Management Constraints TimeCost Performance

7 Opermgt 345 Shannon January, Triple Constraint Trade-offs Budget Schedule EarlyLate TIME $ Performance Specifications Better Worse

8 Opermgt 345 Shannon January, Major causes of failure ØSelection of a unsound project ØSelecting the wrong person as a project manager ØLack of support from upper management ØMisused management techniques ØProject termination not planned

41 Opermgt 345 Shannon January, Slack Time Total Slack = The length of time an activity can be delayed without affecting the project completion time. Total Slack = Late Start - Early Start Total Slack = Late Finish - Early Finish For Critical Activities Free Slack = The time a task can be delayed without delaying another task.
