11. Why Use Heuristics for
Systems Architecting?
Effective for Grand Scale Projects
Helps Dissect Problem
Reduces Solution Space
Re-Use Proven Approaches
Understand Critical Trade-Offs
11/12/2008 Capstone Thesis Defense 11

12. Why Use Heuristics for ITS?
ITS is a Grand Scale, Highly Complex Project
Several Disparate Systems Must Work
Together
Socio-Technical Concerns
Detailed Scoping Required
Many Interfaces, Some Proprietary Others
Open
