The Competition phase consists of individuals architecting the best solution based on the specification document.  Through each contest, participants will create sequence diagrams to display all the messages through the system.  These diagrams are used as the road map to the Assembly contest that will run as a result of this contest.  In addition, participants will identify new and/or existing components to be created or used in the application and define the required interfaces between new components. Each participant is also required to submit a "walking skeleton" of the submitted architecture.  For the purpose of these competitions, a "walking skeleton" is defined as follows:

• A simple proof of concept to validate the architecture. 
• A low functionality working system to which more functionality can be added incrementally. 
• The smallest and simplest path, from front-end user interface input, through the system services and finally to simple, but usable output.

The contest winner will also create new component specs, launch component contests and manage them.
