The Problem

Building high quality software for real-world applications is getting more difficult as the problems get more complex (no more Pong).
Current software engineering methods
- Objects
- Components
- Design Patterns
- Software Architectures (systems of patterns).
are not always enough because they fall short in two main ways.
- The interactions between computational entities are too rigidly defined.
- They lack mechanisms for representing the system's inherent organizational structure.
