2. Build A A Done Build B B Done Build C C Done Build D Ship JAN FEB MAR APR MAY JUN On time! Projects Unique, one-time operations designed to accomplish a specific set of objectives in a limited time frame.

3. Project Management • How is it different? • Limited time frame • Narrow focus, specific objectives • Less bureaucratic • Why is it used? • Special needs • Pressures for new or improves products or services

4. Project Management • What are the Key Metrics • Time • Cost • Performance objectives • What are the Key Success Factors? • Top-down commitment • Having a capable project manager • Having time to plan • Careful tracking and control • Good communications

5. Project Management • What are the Major Administrative Issues? • Executive responsibilities • Project selection • Project manager selection • Organizational structure • Organizational alternatives • Manage within functional unit • Assign a coordinator • Use a matrix organization with a project leader

6. Project Management • What are the tools? • Work breakdown structure • Network diagram • Gantt charts • Risk management

7. Summary of 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

8. Project Manager Responsible for: Work Quality Human Resources Time Communications Costs

9. Feasibility Planning Concept Execution Termination Project Life Cycle Management

14. Gantt Chart Planning and Scheduling

15. PERT and CPM Networks 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

16. The Network Diagram • Network (precedence) diagram – diagram of project activities that shows sequential relationships by the use of arrows and nodes. • Activity-on-arrow (AOA) – a network diagram convention in which arrows designate activities. • Activity-on-node (AON) – a network diagram convention in which nodes designate activities. • Activities – steps in the project that consume resources and/or time. • Events – the starting and finishing of activities, designated by nodes in the AOA convention.

17. The Network Diagram (cont’d) • Path • Sequence of activities that leads from the starting node to the finishing node • Critical path • The longest path; determines expected project duration • Critical activities • Activities on the critical path • Slack • Allowable slippage for path; the difference the length of path and the length of critical path

23. Computing Algorithm • Network activities • ES: earliest start • EF: earliest finish • LS: latest start • LF: latest finish • Used to determine • Expected project duration • Slack time • Critical path

24. Project Management Software • Computer aided design (CAD) • Groupware (Lotus Notes) • CA Super Project • Harvard Total Manager • MS Project • Sure Track Project Manager • Time Line

29. 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

30. Summary • Projects are a unique set of activities • Projects go through life cycles • PERT and CPM are two common techniques • Network diagrams • Project management software available

32. 4 2 1 5 6 3 Limitations of Networks • Important activities may be omitted • Precedence relationships may not be correct • Estimates may include a fudge factor 142 weeks

33. Ethical Issues • Temptation to understate costs • Withhold information • Misleading status reports • Falsifying records • Comprising workers’ safety • Approving substandard work

34. Homework Problem Do problem 5 (part a only) on p. 819. While thesolution is given in the following slides, be sure that you take the time to try to solve this problem prior to looking at the solution.
