We worked with a company to design the next release of their web-based application for localizing web sites and web-based applications to multiple languages and geographical regions. Starting with their use case analysis of over 150 user and system activities, we structured those activities into a sound design, built the basic web pages for that application (HTML, JavaScript, and Java applets), and worked with the development team to get the pages properly implemented in the company's JSP/servlet implementation platform.
