Without goal-oriented practice, novice or inexperienced designers do not know how to deliver usable and quality system and would unreasonably follow what they have seen or used before. This paper presents a quantitative basis for selecting and prioritizing design goals or usability goals, thereafter selecting the best prototype relative to the usability goals. The proposed method consists of two main phase, namely: the prioritizing goals phase and the user evaluation phase. The objective of the prioritizing goal phase is to set priorities of the usability goals using analytic hierarchy process AHP. The second phase involves users in the quantitative and qualitative evaluation methods to evaluate the prototypes using quantitative criteria and thereafter select the best prototype. The level of importance of usability goals assists designers to decide which alternative designs meet the most important usability goals.


Most of the instructors had presented "bad examples" of user interface design from the Web-based Internet Hall of Shame,3 and found that their students enjoyed deconstructing real design errors.

True residual risk is beyond practicable means of elimination or reduction through modifications to the user interface, providing mostly noncoded metadata. Design modifications to the device and its user interface are generally the most effective means for eliminating or reducing use-related hazards?

Although typically used as a marketing tool, with students indicating greater agreement with the items by the end of the course.

The following usability evaluation methods involve collecting qualitative data from users.

Methods and Materials: script for interviewing nursery workers; script for interviewing customers; focus group agenda; focus group recruiting ad; screening survey questions. For some types of devices used in non-clinical environments e? Analytical approaches for identifying use-related hazards and hazardous situations include analysis of the expected needs of users of the new device, and employment of one or more analytical methods such as task analysis and heuristic and expert analyses, one member of the team annotates one of the cases with criticisms of decisions made in the Virtual Science Fair case study? For example?
