Resource Management

• Whats needed
• Where to get them
• When they are needed
• How to use them

3
Resources as a Constraint

• Can affect when tasks can begin
• Can affect when tasks must be done
• Include in schedule
• Obtain Resource precedent for using resource
• Return Resourcefollows using resource
• Obtain Use Return must be same length as
  critical path

4
Developing Resource Needs

• Uncertain in conceptual design
• Function known
• Capacity/Quantity not known
• Certainty increases as detailed design is
  developed
• Update schedule and budget as necessary

5
Resource Trade-offs

• Cost of alternate schedules
• Cost of alternate resources
• Project managers responsibility
• Compare alternatives
• Resources available
• Allocate critical resources

6
Classifying Resources

• Accounting
• Labor
• Materials
• Indirect
• Availability
• Renewable workers, equipment
• Depletable materials, computer time
• Doubly constrained limited quantity and time

7
Project Manager Concerns

• Depletable
• Only available at a certain time
• Expensive
• Resource Output
• Nominal
• Effective

8
Choosing Resources

• Be flexible
• Minimize variety
• Realize limits of more resources
• Maximize utilization of discrete resources
• Maximize utilization of expensive resources
• Consider needs of the organization
• Avoid loss of control (subcontractor, leasing)
• Add resources at bottleneck activities

9
Resource Utilization
Bad
Good

• Change shape of curve by
• Choice of resources
• Using Slack resource leveling
• Crashing

10
Resource Allocation

• If amount of resource availability is less than
  the amount needed
• Use fewer ? take longer
• Split activities
• Overlap activities adjust precedence
  relationships
• Select alternate resources
• Delay project

• Project Planning
• Project Execution
• Purchase
• Operation
• Maintenance
• Disposal

13
Life-Cycle Cost in Project Mgmt.

• Project decisions have cost implications
• Materials
• Capital Equipment
• Implementation
• Operation
• Replacement
