The research issue for this thesis was founded within the RAMESES project, but is specifically concerned with the necessity for SMEs to undertake the activity of business process modelling. The need to understand the `as is' position of an organisation is fundamental to the development, change or implementation of any information or communication technologies (ICT). The primary research question was `are SMEs able to model business processes in such a way that will enable the effective analysis of the organisation in order to enable information systems development change or implementation'. The objective of the research was to develop a method by which this business process modelling activity could be supported in a fashion which was accessible and effective within the target environment. This thesis expounds the benefits of using a critical approach utilizing a combination of qualitative and quantitative research methods within the bounds of a multi-disciplinary research team to enable effective exploration and investigation. The concept of the research life-cycle has developed the notion of appropriateness in method and approach: this is discussed against the values of the critical and realist paradigms. The issues reported in this thesis have been identified as a result of detailed case study analysis of six small organisations in the North-east of England. The conclusions are presented in three sections firstly the conclusions relating to the SME and the appropriateness of the BAM technique developed within the RAMESES project. Secondly conclusions are given in regard to the research methodology and reflections given as to the efficacy of the process. Thirdly reflections and conclusions are presented that relate to the work in relation to its overall critical aims and finally makes suggestions as to how future work could be improved.

In the developed countries, executives who carry the mam responsibility for the achievement of organizational objectives, are introducing Executive Information Systems (EIS), user-friendly software products designed especially to meet executives' internal and external information needs. The use of technology and the need for reliable information on which to base decision-making are issues currently attracting attention in Saudi Arabia, as prerequisites for attaining national development objectives. This is especially true of the private sector, which faces new challenges as a result of the increased role recently given to it by government policy. However, little or nothing is known about the availability and use of EIS in Saudi Arabia. This study, therefore, presents an overview, with international comparisons, of development in EIS, with a detailed investigation of the current situation of EIS in large companies in Saudi Arabia, in particular. A questionnaire survey was carried out among the 100 largest companies (measured by turnover for 1995) in which executives and IS personnel were asked about availability of EIS in their companies, patterns of information use, EIS development approaches and utilization, and users' satisfaction with EIS. The survey revealed that EIS were available in 52% of the 73 responding companies. Companies used and valued internal more than external information, and made little use of the EIS to gain external information. Development of EIS was usually in-house; little use was made of commercial EIS packages. Data tended to be centralized at head office. A major increase in EIS use appears to have occurred between 1991 and 1995 though there are still some "resisters" who do not use the EIS, despite having access to it. Few companies had experienced EIS failure, and respondents were highly satisfied with their systems' usability, cost-effectiveness, development and controllability. The companies' approach to developing EIS and experience with using it were related to company age, turnover, region and type (stock or non-stock). The Saudi experience appears to broadly similar to that reported in Western studies, except in the area of development approach and type of software used. The study concludes by highlighting significant results in terms of the comparison of EIS experience in Saudi Arabia with international experiences, especially in the U.K. and U.S.A.; and factors which may be expected to affect further development of EIS in Saudi Arabia, as well as having implications for education and research in this field.

The primary concern of the present study was to investigate the effective uses of computer-based software in teaching the listening skill in English as a Second Language (ESL) at higher education institutions. It aimed to find out if computer-based software can be used as a teacher replacement or supplement, either at the beginning or end of the listening lesson. This study also aimed to measure students' motivational reactions to instructional materials, to examine students' computer background, to examine any significant relationships between any of the variables and also to see if there are gender differences in any of these. In order to assess the effect of CALL use, an experimental study was carried out.The respondents consisted of 80 post-SPM students enrolled in Intensive English course at KUSZA, Malaysia. Two achievement post-tests and two sets of questionnaires were administered for data collection. The data results were analysed using SPSS (Statistical Package for Social Science) with statistical techniques of ANOVA, analysis of covariance, Pearson's product-moment correlation and t-tests for independent samples. The results of the study revealed that the way computerised material was used made a considerable effect on the achievement of the students. When it was used as a supplement at the beginning of the lesson, the students scored better results than those students received computerised treatment at the end of the lesson. When it was used as a teacher replacement, the students did not score well in the tests. The results also showed that non-computerised treatment was effective for teaching the listening skill.In the light of these results, certain recommendations were made for the teaching of the listening skill in ESL at KUSZA. It was recommended that computerised instruction be used as a supplement to teacher teaching at the beginning of the lesson rather than at the end of it. Further research is needed to be carried out with larger groups of respondents so that the findings can be generalised to other situations.
