By Abdel Nasser H. Zaied Samah Ibrahim Abdel Aal Mohamed Monir Hassan

DOI: https://doi.org/10.5815/ijisa.2013.09.03, Pub. Date: 8 Aug. 2013

Information Systems (IS) are increasingly becoming regarded as crucial to an organization's success. Information Systems Development Methodologies (ISDMs) are used by organizations to structure the information system development process. ISDMs are essential for structuring project participants’ thinking and actions; therefore ISDMs play an important role to achieve successful projects. There are different ISDMs and no methodology can claim that it can be applied to any organization. The problem facing decision makers is how to select an appropriate development methodology that may increase the probability of system success.
This paper takes this issue into account when study ISDMs and provides a Rule-based Expert System as a tool for selecting appropriate ISDMs. The proposed expert system consists of three main phases to automate the process of selecting ISDMs.
Three approaches were used to test the proposed expert system. Face validation through six professors and six IS professionals, predictive validation through twenty four experts and blind validation through nine employees working in IT field.
The results show that the proposed system was found to be run without any errors, offered a friendly user interface and its suggestions matching user expectations with 95.8%. It also can help project managers, systems' engineers, systems' developers, consultants, and planners in the process of selecting the suitable ISDM. Finally, the results show that the proposed Rule-based Expert System can facilities the selection process especially for new users and non-specialist in Information System field.

By Abdel Nasser H. Zaied

DOI: https://doi.org/10.5815/ijieeb.2012.03.02, Pub. Date: 8 Jul. 2012

E-commerce has been predicted to be a new driver of economic growth for developing countries. The SME sector plays a significant role in its contribution to the national economy in terms of the wealth created and the number of people employed. Small and Medium Enterprises (SMEs) in Egypt represent the greatest share of the productive units of the Egyptian economy and the current national policy directions address ways and means of developing the capacities of SMEs. Many factors could be responsible for the low usage of e-commerce among the SMEs in Egypt. In order to determine the factors that promote the adoption of e-commerce, SMEs adopters and non-adopters of e-commerce were asked to indicate the factors inhibiting the adoption of e-commerce. The results show that technical barriers are the most important barriers followed by legal and regulatory barriers, whereas lack of Internet security is the highest barrier that inhibit the implementation of e-commerce in SMEs in Egypt followed by limited use of Internet banking and web portals by SMEs. Also, findings implied that more efforts are needed to help and encourage SMEs in Egypt to speed up e-commerce adoption, particularly the more advanced applications.

An E-Services Success Measurement Framework

By Abdel Nasser H. Zaied

DOI: https://doi.org/10.5815/ijitcs.2012.04.03, Pub. Date: 8 Apr. 2012

The introduction of e-service solutions within the public sector has primarily been concerned with moving away from traditional information monopolies and hierarchies. E-service aims at increasing the convenience and accessibility of government services and information to citizens. Providing services to the public through the Web may lead to faster and more convenient access to government services with fewer errors. It also means that governmental units may realize increased efficiencies, cost reductions, and potentially better customer service. The main objectives of this work are to study and identify the success criteria of e-service delivery and to propose a comprehensive, multidimensional framework of e-services success. To examine the validity of the proposed framework, a sample of 200 e-service users were asked to assess their perspectives towards e-service delivery in some Egyptian organizations. The results showed that the proposed framework is applicable and implementable in the e-services evaluation; it also shows that the proposed framework may assist decision makers and e-service system designers to consider different criteria and measures before committing to a particular choice of e-service or to evaluate any existing e-service system.
