Glossary » requirements analysis
an early phase in user interface design where basic requirements are determined. Typical categories of requirements include target audience and target platform, features of the application, responsiveness, usability benchmarks (e.g. “such and such a task must be completed within 2 minutes”), and the choice of general look and feel guidelines. Requirements are usually established through a combination of analysis and gathering information from target users, through interviews, observation, focus groups, and surveys.
