The size and complexity of websites have grown significantly during recent years. In line with this growth, the need to maintain most of the resources has been intensified. Content Management Systems (CMSs) are software that was presented in accordance with increased demands of users. With the advent of Content Management Systems, factors such as: domains, predesigned module’s development, graphics, optimization and alternative support have become factors that influenced the cost of software and web-based projects. Consecutively, these factors have challenged the previously introduced cost estimation models. This paper provides a hybrid method in order to estimate the cost of websites designed by content management systems. The proposed method uses a combination of genetic algorithm and Multilayer Perceptron (MLP). Results have been evaluated by comparing the number of correctly classified and incorrectly classified data and Kappa coefficient, which represents the correlation coefficient between the sets. According to the obtained results, the Kappa coefficient on testing data set equals to: 0.82 percent for the proposed method, 0.06 percent for genetic algorithm and 0.54 percent for MLP Artificial Neural Network (ANN). Based on these results; it can be said that, the proposed method can be used as a considered method in order to estimate the cost of websites designed by content management systems.

Nowadays organizations require an effective governance framework for their service-oriented architecture (SOA) in order to enable them to use a framework to evaluate their current state governance and determine the governance requirements, and then to offer a suitable model for their governance. Various frameworks have been developed to evaluate the SOA governance. In this paper, a brief introduction to the internal control framework COBIT is described, and it is used to show how to develop a framework to evaluate the SOA governance within an organization. The SOA and information technology expert surveys are carried out to evaluate the proposed framework. The results of this survey verify the proposed framework.
