This paper reports results of a survey that investigated factors affecting the deployment of systems development methodologies by individual systems developers. The results show that relative advantage, compatibility and trialability of a systems development methodology, an individual's experience in systems development and his/her experience in systems development methodologies, management support and peer developer support, and uncertainty about the continued existence of the IS department significantly influence the deployment of systems development methodologies.

This paper analyses the relationship between organisational culture and the perceptions of use, support and impact of systems development methodologies (SDMs) interpreting organisational culture in terms of the competing values model. The results show that organisations with different culture differ in their perceptions concerning the support provided by SDMs and in their perceptions concerning the impact of SDMs on the quality of developed systems and the quality and productivity of the systems development process. The results depend, however, on the respondent groups (developers vs. managers). The findings also suggest that the deployment of SDMs is primarily associated with the hierarchical culture which is oriented toward security, order and routinisation. Also managers' criticality towards the deployment of SDMs in organisation with high rational culture (focusing on productivity, efficiency and goal achievement) is noteworthy.

One of the key challenges in electronic government (e-government) is the development of systems that can be easily integrated and interoperated to provide seamless services delivery to citizens. In recent years, Semantic Web technologies based on ontology have emerged as promising solutions to the above engineering problems. However, current research practicing semantic development in e-government does not focus on the application of available methodologies and platforms for developing government domain ontologies. Furthermore, only a few of these researches provide detailed guidelines for developing semantic ontology models from a government service domain. This research presents a case study combining an ontology building methodology and two state-of-the-art Semantic Web platforms namely Protégé and Java Jena ontology API for semantic ontology development in e-government. Firstly, a framework adopted from the Uschold and King ontology building methodology is employed to build a domain ontology describing the semantic content of a government service domain. Thereafter, UML is used to semi-formally represent the domain ontology. Finally, Protégé and Jena API are employed to create the Web Ontology Language (OWL) and Resource Description Framework (RDF) representations of the domain ontology respectively to enable its computer processing. The study aims at: (1) providing egovernment developers, particularly those from the developing world with detailed guidelines for practicing semantic content development in their e-government projects and (2), strengthening the adoption of semantic technologies in e-government. The study would also be of interest to novice Semantic Web developers who might used it as a starting point for further investigations.
