A Concern is any important property or area of interest of a system that can treat in a modular way. One of the most important Concerns is Usability which is considered one of the key principles in Software Engineering. The importance of Usability Evaluation has dramatically increased due to extremely fast growth in Internet technology. The website design is directly related to the purpose of the website. Website with poor usability can easily destroy the purpose of website. So, the authors have chosen one of the concern “usability” which is the core component of web applications. The purpose of this chapter is to analysis and proposes an appropriate web usability metric for evaluation of universities website. The proposed method will be based partly on a literature study and partly on the survey analysis response by visitors.

1. Introduction

The term separation of concerns was probably coined by Edsger W. Dijkstra in 1982. Separation of Concerns (SoC) refers to the ability to identify, encapsulate and manipulate the software parts relevant to a particular concern. It has emerged as one of the important principles in Software Engineering. Separation of Concerns (SoC) is the principle for better control of software complexity, during development, maintenance and reuse. The main goal of SoC is the ability to deal with a concern (aspect) separately, during maintenance. A good SoC policy is useful to increase software quality and decrease the effort to test, maintain, understand, reuse and document software. For example, in object-oriented paradigm the separated concerns are modeled as objects and classes and in structural paradigm, concerns are represented as procedures(ISO 9241,1998). One of the most important concerns used in web applications is Usability.
