  1. 7-7 Risk Severity Matrix

  2. CHAPTER EIGHT Scheduling Resources

  3. PMBOK – Resource Management • Project human resource management: • Includes the processes required to make the most effective use of the people invovled with the project. • Individual contributors • Etc.

  4. PMBOK – Resource Management • Major Processes • Organizational Planning • Staff acquisition

  5. PMBOK – Resource Management • Organizational Planning • Involves identifying, documenting and assigning project roles, responsibilities, and reporting relationships to either individuals or groups. • Reviewed/revised regularly throughout project • Tightly linked to communications planning

  6. PMBOK – Resource Management Organizational Planning Inputs Process Output Project Interfaces Staffing Requirements constraints Role and responsibility assignments Staffing management plan Organization chart Supporting detail

  7. PMBOK – Resource Management • Staff Acquisition • Involves getting the human resources needed (individuals or groups) assigned to and working on the project.

  8. PMBOK – Resource Management Staff Acquisition Inputs Process Output Staffing management plan Staffing pool description Recruitment practices Project Staff Assigned Project team directory

  9. PMBOK – Resource Management • Team development • Includes both enhancing the ability of stakeholders to contribute as individuals as well as enhancing the ability of the team to function as a team. • Complicated by two bosses.

  10. PMBOK – Resource Management Team Development Inputs Process Output Project staff Project plan Staffing management plan Performance resports External feedback Team Building activities General management skills Reward recognition systems Collocation Training

  11. Types of Project Constraints • Technical Constraints • Physical Constraints • Resource Constraints

  12. 8-1 Constraint Examples

  13. Technical Constraints • Also called logic constraints • Sequence of events for project activities • CPM addresses these • X-Planes

  14. Physical Constraints • Contractual • Environmental • Handled similar to resource constraints • X-Planes

  15. Resource Constraints • Parallel activities hold conflict for resources • Wedding example • One person, many tasks • X-Planes

  16. Types of Resource Constraints • People • Most Important • Materials • Exotic • Equipment • Type Size Quantity • Working Capital • My Driveway

  17. Classification of Scheduling Customer • Time Constrained • Resource constrained Project Manager Time Resources

  18. Time Performance Cost Constrain Enhance Accept Project Priority Matrix Constrain: The original parameter is fixed. The project must meet the completion date, specs. And scope of the project, or budget Enhance: Given the scope of the project, which criterion should be optimized? Accept: For which criterion is it tolerable not to meet the original parameters?

  19. Time Constrained • Resource Utilization focus • Level within Slack

  20. 8-4 Botanical Garden

  21. 8-4 Botanical Garden Results: Reduced resources Required by 25% (from 4 to 3) Did not affect Schedule Why: Some Equipment Not Easily moved. Negatives: Loss of Slack

  22. Resource Constrained Projects • Difficult to manage • No good math models for: • Rules (Heuristics) • Allocation of resources to activities to minimize project delays

  23. Heuristics Rules that Seem to Work • Follow in order: Assign resources according to activities with: • Minimum slack Then if tie: • Smallest Duration Then if still a tie: 3. Lowest Activity Identification Number

  24. 8-7 Resource-Constrained Schedule Through Period 0-1

  25. 8-7 Resource-Constrained Schedule Through Period 1-2

  26. 8-7 Resource-Constrained Schedule Through Period 2-3

  27. Resource-Constrained Schedule Through Period 2-3 Continued Next least slack Assign Least Slack First Least Slack Most Slack

  28. x Nothing to do here Can’t assign activity B, its too large (2+2=4>3 So, must leave C and D alone Resource-Constrained Schedule Through Period 3-4 0

  29. x Nothing to do here Can’t assign activity B, its too large (2+2=4>3 So, must leave C and D alone Resource-Constrained Schedule Through Period 4-5 x -1

  30. x Nothing to do here Can’t assign activity B, its too large (2+2=4>3 So, must leave C and D alone Resource-Constrained Schedule Through Period 5-6 x x -2

  31. Resource-Constrained Schedule Through Period 6-7 Now, we assign activity with least Slack, that is activity B with –2 periods of Slack. Next activity F has least slack so assign x x x x 2 -2 x 1 1 3

  32. Now, we assign activity with least Slack, that is activity B with –2 periods of Slack. Next activity F has least slack so assign Resource-Constrained Schedule Through Period 7-8 x x x x x 2 2 -2 0 x x 1 1 3 3

  33. Now, we assign activity with least Slack, that is activity B with –2 periods of Slack. Next activity F has least slack so assign x x x Resource-Constrained Schedule Through Period 8-9 x x x x x 2 2 2 -2 -1 1 1 1 3 3

  34. Now, we assign activity with least Slack, that is activity B with –2 periods of Slack. Next activity F has least slack so assign x x x Resource-Constrained Schedule Through Period 9-10 x x x x 2 2 2 2 -2 x -2 1 1 1 1 3 3 3

  35. Now, we assign activity with least Slack, that is activity B with –2 periods of Slack. Next activity E has least slack so assign x x x Resource-Constrained Schedule Through Period 10-11 x x x x 2 2 2 2 2 -2 x -2 1 1 1 1 1 -1 x 3 3 3 3
