Emergent Design

TODO:

• Tracer Bullet Development (see Ship It, ch. 4)

• do light-weight, up front design, create a system of mock objects, and add appropriate automated tests
• System Objects: Encapsulate and Separate 
• incrementally add functionality to the system  
• Incremental Improvements: Iterations
• benefits: scalability, encapsulation, decoupled code, parallel code development, flexible to requirements creep
