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.
In contrast, usability engineering (UE) is the research and design process that ensures a product with good usability. Usability is a non-functional requirement . As with other non-functional requirements, usability cannot be directly measured but must be quantified by means of indirect measures or attributes such as, for example, the number of ...
Agile usability engineering is a method created from a combination of agile software development and usability engineering practices. [1] Agile usability engineering attempts to apply the principles of rapid and iterative development to the field of user interface design. Early implementations of usability engineering in user-centered design ...
Nielsen founded the usability engineering movement for efficient and affordable improvements of user interfaces and he has invented several usability methods, including heuristic evaluation. He holds more than a thousand United States patents, [11] [12] mainly on ways of improving usability for technology.
Functionality, usability, reliability, performance and supportability are together referred to as FURPS in relation to software requirements. Agility in working software is an aggregation of seven architecturally sensitive attributes: debuggability, extensibility, portability, scalability, securability, testability and understandability.
Hallway testing, also known as guerrilla usability, is a quick and cheap method of usability testing in which people — such as those passing by in the hallway—are asked to try using the product or service. This can help designers identify "brick walls", problems so serious that users simply cannot advance, in the early stages of a new design.

Usability consultants Rolf Molich and Jakob Nielsen developed this method on the basis of several years of experience in teaching and consulting about usability engineering. Heuristic evaluations are one of the most informal methods [1] of usability inspection in the field of human–computer interaction. There are many sets of usability design ...
