Context of use

Combination of users, goals and tasks, resources, and environment.

Effectiveness

Accuracy and completeness with which users achieve specified goals.

Efficiency

Resources used in relation to the results achieved.

Ergonomics (human factors)

Goal

Intended outcome.

Human-centered design

Approach to system design and development that aims to make interactive systems more usable by focusing on the use of the system and applying human factors/ergonomics and usability knowledge and techniques.

Interactive system

Combination of hardware and/or software and/or services and/or people that users interact with in order to achieve specified goals.

Prototype

Representation of all or part of an interactive system that, although limited in some way, can be used for analysis, design, and evaluation.

Satisfaction

Stakeholder

Usability

Extent to which a system, product, or service can be used by a specified user to achieve specified goals with effectiveness, efficiency, and satisfaction in a specified context of use.

User

Person who interacts with the system, product, or service.

User experience

Users' perceptions and responses that result from the use and/or anticipated use of a system, product, or service.

User interface

All components of an interactive system (software or hardware) that provide information and controls for the user to accomplish specific tasks with the interactive system.

Validation
