Usability requirements: how to specify, test and report usability
Overview of case studies
The main purpose of the PRUE project was to evaluate the business value of introducing the CIF into the purchasing and procurement process for different types of systems in a variety of contractual environments and countries.
One trial is for the originally envisaged role in the acquisition of corporate software (Ericsson/Electrolux). Another extends this to acquisition of a custom-designed web site (Ministry/SEMA). These trials both focus on evaluating whether a new web-based system meets requirements established by prior evaluation of the existing text-based system.
The two other trials assessed the usefulness of the CIF in negotiating for improvements in a custom-designed system, by evaluating the usability of an existing product to establish requirements for an improved version. The in2netlogic/prezzybox. com trial was in the UK where usability is well-established as an issue, and Robissa Travel/ExcelSoft was in Greece where usability is less well recognised.
