It is managed by the ISO Committee 159 Ergonomics of human-system interaction.It was originally titled Ergonomic requirements for office work with visual display terminals (VDTs).Usability is the ease of use and learnability of a human-made object.
The term conceptual model may be used to refer to models which are represented by concepts or related concepts which are formed after a conceptualization process in the mind.
ISO 9241 is a multi-part standard from the International Organization for Standardization (ISO) covering ergonomics of human-computer interaction.
The design of this diversity of applications so that they actually achieve their intended purposes in term of ease of use is not an easy task.
Although there are many individual methods for evaluating usability; they are not well integrated into a single conceptual framework that facilitate their usage by developers who are not trained in the filed of HCI.
