A Specific Software Development Process for an Electronic Commerce Portal
3.4. GUI development
The graphical user interface for an EC/EB system is developed in two steps. First, a user interface prototype is designed. This prototype is also used by marketing to support accompanying advertising measures.
The prototype development begins with writing a storybook that is based on the use cases. This storybook is then used to define a style guide and, in a second step, to realize and implement the user interface for the EC/EB system. For the IPSI electronic commerce portal, this was done for multiple access channels (WWW, WAP).
Besides the portal's specific functionality in the B2E application domain, its content is also a significant element. The content comprises all the information that the electronic commerce portal provides, as well as its presentation within the user interface. Content often has multi-media characteristics, i.e. it comprises textual information, graphic figures, moving and still pictures and audio information. Consequently, a content manager who is responsible for the multi-media information is an important role in the software development process. This is a new role that can comprise other roles, such as the media author who collects information and reworks it for a consistent presentation; the media designer who is responsible for the audio-visual design of the user interface; and the media producer who researches available media, creates images, graphics, animations, audio and video sequences, and clarifies copyright issues. Media editors are responsible for quality assurance in the multi-media content part of the application.
In addition to the role of content manager with its many tasks and responsibilities, the role of ergonomics advisor has to be taken by a team member. The ergonomics advisor's task is to ensure that the user interface of the electronic commerce portal is design ergonomically, i.e.
User manuals can be differentiated into tutorials and references. For the creation of the user manuals, a styleguide is used that describes what the complete user documentation will look like. For the creation of a tutorial, the storybook that was already used for the user interface prototype is used again.
