Roles: Interaction design, use modeling, graphic design, HTML prototyping, usability testing.

Project Details: Cellmania mEnterprise is a software platform based on existing Cellmania technology, enhanced to enable users to easily build mobile applications for delivering smart content.

The specs detailed a very complex application. Cathy worked with the marketing and engineering groups to determine objectives, strategy and development limitations. Then she organized the user tasks into a preliminary navigation model. After drawing paper prototypes, Cathy expanded the navigation model into a use model, adding all user interaction. Next, complete HTML mockups were built, and the development team began implementing the application. A very basic usability test was conducted with the mockups. Some changes were incorporated into the mockups and into the application.

The "Locations" section of the application. Users create and manipulate a tree of locations, such as sales territories, for their products and can later use these to apply pricing rules based on location.		Creating a new content type. In this example, the user imported a table from an external database. The user can also add local fields to this set.

Editing a data record. This example shows a rule applied for the price.		The end of result of Business Station is the generation of DTDs (document type definitions) that developers use to create mobile applications and call the data. This example shows the process for creating a custom DTD.
