Usability engineering process model


Amir Ali, Dr. Javed Ferzund, Abdul Jabbar

Usability is most often defined as the ease of use and acceptability of a system for a particular class of users, carrying out specific tasks in a specific environment. For improving user interface different usability engineering methods were suggested by different usability engineers. These Methods /Techniques assist the process of user interface development; included as Heuristic Evaluation, Participatory Design, Cognitive Walk Through, Task Analysis and Rapid Prototyping. These techniques vary considerably in the extent of user involvement that they require. However in recent age not much concentration is given to usability engineering issue during testing. Evaluator mostly have not the complete knowledge, tools and time to tackle usability as complete engineering.rnUsability engineering term has been widely used but rarely adopted as complete engineering. It is in most confused with some part as usability evaluation, testing and analysis. This research will list down all the activities of usability engineering and proposed a complete process model of usability engineering. The mentioned activities can be requirement, scope, design, and development of user interface, in addition to usability evaluation.rnMany studies had revealed that a usability problem causes quality problems in software product. Potential problems lying in interface design, operating process or product structure also contributes to usability problems which resulted in lower effectiveness, efficiency and difficulty of use for end users.rnThe purpose of this study is to discuss about all available methods of usability engineering at one platform and also do comparison between these methods by different aspects and major topic is to define a usability engineering process model. Different engineering approaches (like model –based, prototyping, ontology driven,) will be studied to design a complete process model for usability engineering. This research also has a case study of a telecommunication organization which presents the results of empirical study of usability evaluation which was based on Usability Engineering process model in addition to usability evaluation. rnIn this research paper we also included a survey result of different visual formats of web application by applying usability engineering methods and process model. A comparison of two web based projects PTCL and Mirchi Masala is also included. More ever a comparative statement of various characteristics of newly designed web application (after applying UEPM) is also included.
