Designing Effective Speech Interfaces

Analysis

In the analysis phase, the second phase, you determine who your users are, how they work, and how you expect them to work in the future when they have the software whose interface you are designing. When analysis is complete, you have a description of the requirements of the interface from the user's point of view. The analysis is critical work that feeds directly into design. The deliverable for this second phase is the analysis document and the steps included in this phase are outlined in Table 11.2.

Historically, analysis for interface design has either not been done at all or has not been given enough time and attention to be truly effective. If you don't have this critical information, how can you possibly design an interface that will be easy to learn and use? Without proper analysis, you may spend as much as 10 times the amount of money later, to rework the design.

Define Usability Vision

The vision statement answers the question: What are the goals and priorities? The vision statement concentrates on usability, not technology. Later in the analysis, you will get more specific with usability ...
