Several multilingual marketplaces and portals have been build using an "agile" analysis and development methodology, a rigid quality control process and the ArsDigita development platform. Several Powerpoint slides that document these processes are publicly available as part of the collaboration with the La Salle University:

• Development at Competitiveness.com
  A PDF presentation about the analysis and development process at Competitiveness.com.
  
  
• ArsDigita Training Plan
  This document is part of the standardized training plan at Competitiveness.com. The ties to Universities allow for an efficient recruiting and training of new developers and for access to firsthand information about the current technology environment.
  
  
• Operations and Quality Guide
  This presentation documents the staging and quality control processes that allow for highest application availability while allowing for continuous development.
  
  
• Multilingual Architecture
  An article documenting the decisions and tradeoffs when implementing multilingual architectures.
