  1. Manager’s “diamond” for Project Variables cost Target: 100% Target : $70K schedule scope Target : 30 wks Target : 4 defects/Kloc quality Adapted from Software Engineering: An Object-Oriented Perspective by Eric J. Braude (Wiley 2001), with permission.

  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 Adapted from Software Engineering: An Object-Oriented Perspective by Eric J. Braude (Wiley 2001), with permission.

  5. Optimal Size for Interaction (Approximate) Effectiveness per developer Approximate optimal range Developer communicates regularly with eleven people. Communication time outweighs benefits of interaction Developer communicates regularly with no one.
