IT Project Management: Chapter 4 Resource Plan and Cost Estimation

Assigning Resources

A schedule is not complete until all the resources necessary to complete the project have been committed or assigned.

• Non-Labor Resources
• Lab time
• Facilities
• Prototype parts/systems
• Equipment
• Materials

The Resource Problem

Resources and Priorities, Project network times are not a schedule until resources have been assigned.The implicit assumption is that resources will be available in the required amounts when needed. Adding new projects requires making realistic judgments of resource availability and project durations.Cost estimates are not a budget until they have been time-phased.

Resource Smoothing (or Leveling)
Involves attempting to even out varying demands on resources by using slack (delaying noncritical activities) to manage resource utilization when resources are adequate over the life of the project.

Resource-Constrained Scheduling
The duration of a project may be increased by delaying the late start of some of its activities if resources are not adequate to meet peak demands.

Types of Project Constraints

Technical or Logic Constraints
Constraints related to the networked sequence in which project activities must occur.
Physical Constraints
Activities that cannot occur in parallel or are affected by contractual or environmental conditions.
Resource Constraints
The absence, shortage, or unique interrelationship and interaction characteristics of resources that require a particular sequencing of project activities
Kinds of Resource Constraints
People, materials, equipment
