2. The Variables of Project Management
Can somewhat vary the following factors.
1. The total cost of the project,
e.g., increase expenditures
2. The scope of the product,
e.g., subtract from a list of features
3. The quality of the product,
e.g., increase the mean time between failure
4. The date on which the job is completed.
e.g., reduce the schedule by 20%
e.g., postpone project's completion date one month

4. Optimal Size for Interaction (Approximate)
Effectiveness per developer
Developer communicates regularly with no one.
No communication time lost, but developer is too isolated and has no help. 3
Number of people with whom developer must frequently interact
