Usability engineers sometimes work to shape an interface such that it adheres to accepted operational definitions of user requirements documentation.For example, the International Organization for Standardization approved definitions (see e.g., ISO 9241 part 11) usability are held by some to be a context, efficiency, and satisfaction with which specific users should be able to perform tasks.
