Web accessibility is growing in importance as each day goes by. Alongside this growth, is also the need for access to web resources, by those with some sort of disability. The web is very important for spreading information and for the interaction between the various society elements.

This obligation should be greater for enterprises where the web is used as a marketing and business platform. With this paper we would like to present a study with indicators regarding the accessibility levels of Portuguese enterprises websites and, we would also like to present a brief comparison between the accessibility levels of the 1000 largest Portuguese enterprises websites and the accessibility levels of the 1000 best Portuguese SMEs websites.

Abstract
It is imperative for an organization to identify potential constraints to e-business in order to minimize the risk derived from its c-business initiative. Hence, in this paper, we have used a maturity stage model (Stages Of Growth Model for c-business SOGe) to identify the maturity stage of the biggest Portuguese enterprises and to report the findings of a study that sought to explore a range of constraints that the literature suggests influences c-business evolution, so that organizations could be better equipped in anticipating any difficulties while in progress through their. e-business initiatives. Questionnaires were applied to investigate the research problem. It was administered to 1000 managing directors of the biggest (according to the amount of business) Portuguese enterprises. Results suggest that Portuguese enterprises had a positive evolution between 2005 and 2007, and that, in lower maturity stages, the constraints are more significant.

Abstract
Maturity models describe the maturing of the use of information systems in organizations. They are a useful framework to describe an organization's current position as well as a range of possible position in the future in terms of their e-business maturity. The relationship between Information Technology (IT) and e-business maturity is examined. We used a model of c-business maturity, Stages Of Growth for e-business (SOGe) model, to put an organization in a maturity stage. In our survey we presented a set of technologies and we asked to enterprises which of them are implemented, in development, planned or inexistent. We concluded that there is a strongly correlation between IT implementation and the e-business maturity.
