Usability Processes and Techniques
“If you can't describe what you are doing as a process, you don't know what you're doing.”
W. Edwards Deming
A good user interface doesn't just happen. It requires a proven process for success. The process needs to be efficient and produce specific deliverables that will be used as input when creating the interface. These deliverables include simple minimalist pieces of documentation, which are created at each step in the process.
Although best practice for design processes vary for speech versus graphical versus Web interfaces, there are more similarities than differences. This chapter, therefore, describes how to apply our standard design process, InterPhase 5, originally designed for GUIs, to the design of speech interfaces.
