USABILITY of WORKPLACES

Usability means:
The extent to which a product can be used by specified users to achieve specified goals with effectiveness, efficiency and satisfaction in a specified context of use [ISO 9241-11]. Usability can not be evaluated on the product  - only in the situation of use that depends on users’ values in culture, context, time and situation. Usability has partly to do with the properties of the product, but even more with the process of design and use.
Functionality means:
Those practical effects derived from the physical properties of a product that might result in usability in certain situations for certain users. Functionality can be evaluated on the product.

This will be further discussed and elaborated in this section.
