Each function is divided into a set of specific activities. A list of the project team members most likely to be involved in a function is also included as well as a list of the interim products likely to come out of that function. Actual multimedia development projects will include some of these activities and not others. Additional activities not included in this model may be required. The team make-up and the specific interim products will also vary considerably according to the nature of a real-world project. Eye4Tech "Multimedia Design Model" includes four major functions that guide a project

1	Analysis	Definition	Information Design
2	Design	Architecture	Interaction Design
3	Production	Design	Presentation Design
4	Evaluation	Implementation	Compilation

We use the Unified Software Development Process, a generalized set of activities that can be customized to transform your requirements into a software system, to accomplish project goals. Today the trend in software is towards bigger, more complex systems. This trend has also been influenced by the expanding use of the Internet for exchanging all kinds of information-from plain text to formatted text to pictures to diagrams to multimedia. We want software that is better adapted to our needs but that in turn makes the software more complex. We also want it faster which makes time an important constraint. These demands for powerful, complex software require a more controlled way of working they require a process that integrates the many facets of software development that provide guidance to the order of a team’s activities. Eye4Tech "Unified Process" includes five major functions that guide a project
