Developing innovative tool to enhance the effectiveness of decision support system

This research centres on Usability Evaluation Methods (UEMSs) with the aim of supporting developers’ decisions in the use of learning resources in achieving efficient usable system design. The suggestion is made pertaining to a new usability evaluation model dEv (stand for Design Evaluation) with the objective to support decisions to overcome three key obstacles: firstly, the involvement of users in the preliminary stages of the development process; (2) developers’ mind set-related issues as a result of either their lack of UEMS or the provision of too many; and (3) the complete lack of understanding surrounding UEMS importance. An experimental approach was applied in addition to a survey-based questionnaire in an effort to examining the issues pertaining to UEMS. Empirical works were carried out with system developers in order to test the dEv, the results of which have been presented from the empirical study to support various considerations, such as: system developers’ decisions and their involvement in the earlier phases of the design of systems; the gathering of specifications and end-users’ feedback; and enhancing usability evaluation learning capacity
