The difference

Instead of written documents which are hard to understand, requirements are specified visually through an interactive mockup based on best practices

It comprises:

1. Hierarchical description of goals, sub-goals and methods based on collected data
2. Analysis of how information is treated to achieve sub-goals and goals
3. Integration of user knowledge and business rules in specifications

1. Alignment of tasks and information representation using human factors and industry best practices
2. Model optimization based on how people treat information

1. Mapping of captured requirements data onto user interface using standards drawn from best practices
2. Generation of optimized user interface
