Item Quality aspects of software product supply and support using the Internet(1998) Braude, Bruce ShaunThis project explores the use of the Internet to supply and support software products within a quality management system. The Software Engineering Applications Laboratory (SEAL) at the University of the Witwatersrand is in the process of developing various software products that will be commercially distributed in the near future. The SEAL has chosen to use the Internet to supply and support these products. A system has been developed for this task and has been named the Internet System for the Supply and Support of Software (IS4). The SEAL is committed to developing and supplying software within a quality management system. Consequently an investigation was undertaken into the quality characteristics and requirements based on the ISO 9001 standard for quality assurance and the ISO/lEC JTG1/SC7 software engineering standards. The investigation focused on quality requirements for processes related to supplying and supporting software as well as on the quality characteristics of the IS4 and the IS4 development process. These quality concerns have been incorporated into the SEAL's quality management system, the design and development of the IS4 and the development process for SEAL products. Major technical issues that have influenced the design of the IS4 have been the control of the supply and licensing of the supplied products and the transaction processing of the on-line sales. To control the supply and licenSing of the supplied products, various issues such as unlock keys, Internet based registration, controlled access and hardware control have been investigated. The advantages and disadvantages of each have been investigated and a suitable lmplernentat'on has been used in the IS4. To process the on-line transactions the IS4 will be developed to be compliant with the recently released 'Secure Electronic Transactions' (SET) standard. The project has been managed in accordance with the SEAL's Quality Management System (QMS) which is ISO 9001 compliant. The system contains a Shopper Interface for purchasing of SEAL products and a Manager Interface for administration of the system. The Microsoft BackOffice® set of software has formed the foundation on which the system has been developed. One of the focuses of the project was maintainability of the IS4. Documentation and procedures have been developed to aid in administration and perfective maintenance in the future.Item Culture as a moderator for the infusion of Web 2.0 technology: TAM vs WebQual(2012-06-29) Hammerich, WestleyIt is clear that the internet is being used more often for social interactions but the reasons why people adopt these newer technologies are still unclear. Over the last thirty years numerous adoption theories have been proposed however few account for the newer types of technology, such as social website usage. Purpose – The study will compare and contrast two different models of adoption to see if one model is better than the other in understanding the usage of social networking websites such as Facebook. At an organisational level the idea of extended usage of technology has been encapsulated in the construct of infusion of technology into a work place. The study will also show that infusion of technology may occur at an individual level of research. The argument is made that since national culture has been shown to affect usage, national culture may moderate the level of infusion that is found. Methodology – The study will use a quantitative methodology to survey potential (or actual) users of Facebook using a structured questionnaire. Since two adoption models are being tested, two questionnaires were developed and tested. The items for the questionnaires have been adapted from prior literature. Reliability and validity tests confirmed the scales from prior literature. The sample was selected from higher education institutions within the Johannesburg region .Specifically, students from the University of the Witwatersrand and the University of Johannesburg were invited to complete the questionnaires. The two questionnaires were mixed randomly between the students. Findings – It was found that the traditional technology acceptance model could better explain the usage of social networking websites when compared to the more modern WebQual framework. The study found that there is a strong positive relationship between usage and infusion. In line with the prior research on national culture moderating usage, the study found that national culture does moderate the relationship between usage and infusion. Implications – The study has a number of implications. Firstly, the research compared two models of technology usage. The study showed that the technology acceptance model was better at explaining the usage of social networking websites. Future research should focus on improving the TAM model and may result in better understanding the usage of social websites. Secondly, a set of scales are provided for future research which allow for the measurement of infusion at an individual level. These scales were tested for reliability and validity in two separate data collections and in both collections the scales met or exceeded the statistical requirements. Thirdly, the relationship between usage and infusion is seen to be moderated by national culture. This has 5 large implications for organisations and people who use Web2.0 as a medium for business. As an example, marketers could use the results in better understanding the usage of these types of websites, in the hope that it would allow for better targeting and placement of adverts. Lastly, the implications may extend beyond the context of the research. The study found a relationship between usage and infusion at an individual level of analysis. The relationship may exist in other areas of research which relate to Information systems including but not limited to Marketing (increasing the life cycle of products and increasing the value of customers through brand loyalty) and human resources (increasing employee efficiency through understanding peoples infusion of different types of technology). Research limitations – The research is limited to the sample that was achieved. The findings can be directly inferred to a similar sample base within South Africa, however cannot be generalised to samples of dissimilar natures. While the study used Facebook as a case, it should be cautioned that the results should not be generalised to other forms of social networking websites such as Twitter. Originality – The study is original in the following ways: Firstly, the study was conducted in South Africa where few other studies been found with a similar nature. Secondly, the study extended the thoughts on usage to the idea of infusion. Thirdly, two models were directly compared with independent data collections occurring. Fourthly, the relationship between usage and infusion is seen to be moderated by national culture. Both the relationship as well as the moderation effects has previously been empirically shown.Item E-governance in Africa: governing the continent through AU and Nepad websites(2008-04-21T07:16:31Z) Mukhudwana, Rofhiwa FeliciaAfrica’s way forward requires integration, democracy, good governance, participation and inclusive communication of all issues. Intergovernmental organizations are essential to facilitate the above mentioned goals. New thinking highlights the role of new media especially the Internet in democracy and governance in Africa. Therefore, the question solicited here is whether e-governance facilitates continental governance in Africa and under what circumstances would this be possible? This research introduced the internet (web) as a distinct medium of communications with distinct features and characteristics. A number of scholars argue that the Internet as a distinct medium of communication can better facilitate the democratizing role of the media in society, while others argues that the internet has not changed the nature of politics since ordinary politics in all its complexity and vitality has invaded and captured cyberspace. These arguments are divided respectively between Technological Determinism and the Social Shaping of Technology. This research investigates (AU, EU and Nepad) e-governance websites in order to understand practices, prospects and challenges of continental e-governance systems. It was found that the AU and Nepad use the websites for institutional information rather than interaction with citizens and online service delivery. However, significant steps are taken to enhance interaction in Nepad. It is therefore recommended that, the AU and Nepad need to invest time and commitment in enhancing interactivity and rising awareness for these e-governance systems. As projected, EU performs much better than the above two in terms of interactivity. This is because it has more experience and internet penetration and uses is widespread in Europe than it is here in Africa.
