CHAPTER EIGHT Scheduling Resources

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.

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

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

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

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

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

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.

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

8-1 Constraint Examples

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

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

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

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

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

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?

Time Constrained • Resource Utilization focus • Level within Slack

8-4 Botanical Garden

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

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

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
