- Description: This study locates the Blackboard Learning Management System as a Technology Enhanced Learning tool within the bounds of the discipline of eLearning and aimed to interrogate the use of Blackboard for the purposes of teaching, learning and assessment in large classes. It is evident from the literature reviewed that changes in both Higher Education in the South Africa with regards to policy and legislation in addition to international shifts towards increased access and participation in a fast paced, ever-evolving knowledge-based economy, providing the context for this work. The theoretical framework for this study is not unidimensional due to the fact that the educational field of eLearning as an area of specialisation draws on a multitude of theories in terms of their utility value for instructional design of courses utilising Information and Communications Technology as a mode of delivery. This study was conducted within the bounds of an interpretivist paradigm as the researcher sought to focus on the use of Blackboard and the experiences of the lecturers and students involved in the implementation thereof. The research design for this study took the form of a case study and a multiple case method was employed. The researcher collected data through personal interviews conducted with participating lecturers, while student data was collected by means of a qualitative survey which was conducted through the Blackboard Learning Management System. The data was analyzed by means of a thematic analysis, consistent with the interpretive paradigm chosen for this study. The findings of this study revealed that Blackboard was utilised effectively in order to facilitate communication, access to course resources and promoted more efficient assessment processes. The implementation was however not without challenges many of which were systemic and focused on the lack of resources available to the students. The implications of using Blackboard for teaching and assessment of large classes include the use of the Learning Management System as part of a multimodal method of course delivery in an effort to reach the multitude of registered students both conceptually as well as electronically. The recommendations arising from this study include consideration on the part of the faculty for a unified approach in the use of Blackboard for communication as well as deployment of resources. Additionally, this study may form the foundation of further studies in this field, with a focus on the active engagement and training of lecturers in order to integrate traditional teaching methods with blended learning opportunities.

- Description: SAs are documents that specify the business relationship between stakeholders to an outsourcing agreement. SAs specify this relationship in a legally binding manner that assists in managing expectations of the stakeholders about the service provision. According to Verma (1999), an SA is a precise statement of the expectations and obligations that exist in a business relationship between two organisation: the service provider and the client. In order for organizations to have successful outsourcing partnerships, they need well crafted methods of developing Service Agreements (SAs). Successful methods will produce a conclusive contract that will act as a working document that details the spirit of cooperation between the service provider and the service recipient. This research investigates the development of SAs in the Information and Communication Technology (ICT) sector, and proposes a model for their development. A number of models for SA development have been analysed. Models are analysed from leading researchers in the area, from software houses such as Microsoft and from international standards organisations such as the BS15000 which stipulates the ITIL framework. Eight development principles are identified and explored. An investigation into SAs and their development is conducted. A model is proposed that is composed of the development principles. The development of SAs was explored in an empirical study by means of a survey administered to industry practitioners and a series of interviews with managers in the ICT industry. The results of the study indicate varying levels of support for the development principles and limited relationship between the development principles and the success of the SA, as defined by the number of changes made to the SA after it is completed.

- Description: Despite the demand for ICT skills, businesses are experiencing an ICT skills shortage. Constantly changing ICT technologies require business leaders to find qualified ICT professionals to implement new business strategies and business processes. The Information and Communications Technology (ICT) sector is experiencing a continued skills shortage and various initiatives have been launched to address the problem. Businesses continually struggle to find qualified and suitably skilled ICT personnel. As a result businesses have had to outsource their ICT requirements off-shore to obtain the required ICT skills and maintain their competitive advantage. In a country desperate for job creation, entrepreneurial inclination and start up of new businesses may play a pivotal role in the economic development and well being of individuals able to capitalise on the availability of ICT opportunities. Entrepreneurship is a critical factor in promoting innovation, creating employment opportunities and generating social and economic wealth in a country's economy. Sectors such as Information and Communication Technologies can be seen as archetypal entrepreneurial industries and can consequently play a key role in economic development. In the research that follows the author identifies an ICT skills shortage in South Africa. This is followed by an exploratory study that investigates the influence of psychological traits and socio-cultural variables on the entrepreneurial intent of selected ICT SMME’s in the Nelson Mandela Metropolitan Area. The findings revealed that both psychological traits together with socio-cultural variables influence an individual’s intention to start up a business. The predominant psychological trait discovered during the research was perseverance. Family environmental issues were the dominant socio-cultural variable influencing entrepreneurial intention amongst the case study subjects.

- Description: With the growth in the use of technology in sports, there has been an improvement in sporting performances. Some may argue that the two go hand in hand, while others will write it off as coincidence. Nevertheless the use of technology in sport is seen on a daily basis. Cricket uses Hotspot, tennis uses Hawk-Eye and rugby uses slow motion video replays. In these sports codes, technology is already an aid to umpires. Little is known, however, about the technologies used to assist coaches in sports codes such as netball. This study investigated the factors impacting the introduction of information technology in the coaching of netball. The study commenced with using the term technology in the broader sense of the word to gain an understanding from netball coaches as to how technology could be incorporated into the sport. It was later narrowed down more specifically to computer technologies. The investigation was done at the Spar National Netball Championships in 2012, where coaches were surveyed about the preparation for the tournament of the provincial teams. The surveys included questions to coaches regarding the technologies used in preparation for a national tournament. The results obtained from the coaches were used to identify the current technologies used. Interviews were conducted after the analysis of the initial results to probe into the potential use of social media as a tool to assist coaches. Based on the results of the study, a number of factors that impact on the introduction of technology in the coaching of netball were identified. The factors and basic guidelines were validated through expert focus groups. Based on the findings from the experts, the factors and guidelines were refined. It is envisaged that the findings from this research can be used to assist netball coaches in deciding how to introduce the use of information technology into the sport.

- Description: Information and Communication Technology (ICT) has become critical and pervasive in any well-run modern enterprise across all sectors, which include local government. As a result, ICT demands to be managed and governed in a sustainable manner. Therefore, local government should accept the responsibility of implementing good Corporate Governance of ICT (CGICT). Without sound CGICT, ICT is unable to support local government in the achievement of their strategic objectives. This will most likely result in local government not being able to serve the interests of the community. Even though local government is aware of their responsibility regarding CGICT, the Auditor-General reports that their attempts are unsatisfactory, in this regard. This is most probably due to the fact that ample information exists on guiding local government with `what' they should do towards good CGICT, but unfortunately a lack of guidance on `how' to achieve it. Thus, it is imperative for local government to adopt a CGICT framework which provides guidance not only on what they must do towards implementing good CGICT but also on how they should achieve it. In doing so, local government would most likely be able to properly manage and govern ICT and support the needs of the community. Therefore, the aim of this study is to report on research undertaken, in order to assist local government with a CGICT framework that is relevant to their unique environment. Accordingly, this CGICT framework aims to be usable and scallable to the needs of any sized local government entity. As a result, the CGICT framework aims to be simplistic in nature to promote self-implementation of sound CGICT in local government.

- Description: Even though many organizations invest in IT, the value that IT is expected to contribute is still not clearly understood. Researchers agree that IT has become a crucial element to business operations and business existence. However, while there is continued investment in new information technologies and systems, organizations are not certain whether significant value is derived from IT investments. The failure to realize good return on IT investments is ascribed to a lack of understanding of IT by organizations and also the failure by organizations to align IT strategies with business strategies. The lack of alignment leads to the failure to match the right IT to the correct task, which leads to the poor application of systems and poor allocation of human resources to tasks. Therefore, organizations such as Small and Medium Enterprises (SMEs) in particular Boutique Hotels, are noted for their failure to derive better IT value. Their unique characteristics are understood to be influential in the way IT is used and managed by affecting the delivery of value from technology. In order to enable Boutique Hotels to derive more value from IT, the IT governance frameworks, Val IT and CobiT (ITGI, 2007), were examined as these integrate good practices to ensure that an organization‘s IT supports the business objectives. In addition, the Task Technology Fit (TTF) (Goodhue and Thompson, 1995) and Gap Analysis (Heeks, 2001) theories were highlighted as these prescribe the platform ideal for more value to be derived from IT. The current status of Boutique Hotels in Buffalo City was assessed through the use of questionnaires and interviews. The collected data was analyzed and resulted in the development of a model that can be used by Boutique Hotels in order to derive more value from IT and to maximize the use of IT.

- Description: The amount of information produced by different domains is constantly increasing. One domain that particularly produces large amounts of information is the legal domain, where information is mainly used for research purposes. However, too much time is spent by legal researchers on searching for useful information. Information is found by using special search engines or by consulting hard copies of legal literature. The main research question that this study addressed is “What techniques can be incorporated into a model that recommends the most applied case for a field of law?”. The Design Science Research (DSR) methodology was used to address the research objectives. The model developed is the theoretical contribution produced from following the DSR methodology. A case study organisation, called LexisNexis, was to help investigate the real-world problem. The initial investigation into the real-world problem revealed that too much time is spent on searching for the Most Applied Case (MAC) and no formal or automated processes were used. An analysis of an informal process followed by legal researchers enabled the identification of different concepts that could be combined to create a prescriptive model to recommend the MAC. A critical analysis of the literature was conducted to obtain a better understanding of the legal domain and the techniques that can be applied to assist with problems faced in this domain, related to information retrieval and extraction. This resulted in the creation of an IE Model based only on theory. Questionnaires were sent to experts to obtain a further understanding of the legal domain, highlight problems faced, and identify which attributes of a legal case can be used to help recommend the MAC. During the Design and Development activity of the DSR methodology, a prescriptive MAC Model for recommending the MAC was created based on findings from the literature review and questionnaires. The MAC Model consists of processes concerning: Information retrieval (IR); Information extraction (IE); Information storage; and Query-independent ranking. Analysis of IR and IE helped to identify problems experienced when processing text. Furthermore, appropriate techniques and algorithms were identified that can process legal documents and extract specific facts. The extracted facts were then further processed to allow for storage and processing by query-independent ranking algorithms. The processes incorporated into the model were then used to create a proof-of-concept prototype called the IE Prototype. The IE Prototype implements two processes called the IE process and the Database process. The IE process analyses different sections of a legal case to extract specific facts. The Database process then ensures that the extracted facts are stored in a document database for future querying purposes. The IE Prototype was evaluated using the technical risk and efficacy strategy from the Framework for Evaluation of Design Science. Both formative and summative evaluations were conducted. Formative evaluations were conducted to identify functional issues of the prototype whilst summative evaluations made use of real-world legal cases to test the prototype. Multiple experiments were conducted on legal cases, known as source cases, that resulted in facts from the source cases being extracted. For the purpose of the experiments, the term “source case” was used to distinguish between a legal case in its entirety and a legal case’s list of cases referred to. Two types of NoSQL databases were investigated for implementation namely, a graph database and a document database. Setting up the graph database required little time. However, development issues prevented the graph database from being successfully implemented in the proof-of-concept prototype. A document database was successfully implemented as an alternative for the proof-of-concept prototype. Analysis of the source cases used to evaluate the IE Prototype revealed that 96% of the source cases were categorised as being partially extracted. The results also revealed that the IE Prototype was capable of processing large amounts of source cases at a given time.

Furthermore, appropriate techniques and algorithms were identified that can process legal documents and extract specific facts. The extracted facts were then further processed to allow for storage and processing by query-independent ranking algorithms. The processes incorporated into the model were then used to create a proof-of-concept prototype called the IE Prototype. The IE Prototype implements two processes called the IE process and the Database process. The IE process analyses different sections of a legal case to extract specific facts. The Database process then ensures that the extracted facts are stored in a document database for future querying purposes. The IE Prototype was evaluated using the technical risk and efficacy strategy from the Framework for Evaluation of Design Science. Both formative and summative evaluations were conducted. Formative evaluations were conducted to identify functional issues of the prototype whilst summative evaluations made use of real-world legal cases to test the prototype. Multiple experiments were conducted on legal cases, known as source cases, that resulted in facts from the source cases being extracted. For the purpose of the experiments, the term “source case” was used to distinguish between a legal case in its entirety and a legal case’s list of cases referred to. Two types of NoSQL databases were investigated for implementation namely, a graph database and a document database. Setting up the graph database required little time. However, development issues prevented the graph database from being successfully implemented in the proof-of-concept prototype. A document database was successfully implemented as an alternative for the proof-of-concept prototype. Analysis of the source cases used to evaluate the IE Prototype revealed that 96% of the source cases were categorised as being partially extracted. The results also revealed that the IE Prototype was capable of processing large amounts of source cases at a given time.

- Description: In recent years the field of Business Process Modelling (BPM) has gained increasing attention from both the business and research communities. One of the primary drivers for BPM is the improved understanding of Business Processes (BPs) and the competitive advantage gained over competitors. In addition, BPM can improve communication in an organisation and facilitate increased support for change management. BPM is a collaborative activity that needs to be carried out in a team environment, and Collaborative Business Process Modelling (CBPM) promotes improved readability, accuracy and quality of process models as well as a reduced workload for modellers. In spite of the increased popularity of CBPM, there is limited research related to the collaborative nature of the modelling tasks performed by modellers and specifically to the synchronisation of shared process models. In addition, tools and techniques to support CBPM do not support this synchronisation effectively or efficiently. This study proposes a conceptual framework for CBPM using touch technologies in a colocated collaborative environment. The main research problem addressed by this study is that modellers experience difficulties conducting BPM activities in a co-located collaborative environment. In order to address the research problem and clarify and elaborate on the problems of CBPM, a two-fold approach was undertaken. Firstly, after an in-depth literature review, a BPM survey was designed and then sent to modellers in South African Information Technology (IT) consulting companies in order to provide a more in-depth understanding of the status and challenges of CBPM in IT consulting organisations. The results revealed that available BPM software do not adequately cater for CBPM and software tools do not enforce versioning and synchronisation. In addition, hardware constraints were reported as well as problems with integrating different parts of the process model that the modellers were working on. The results of the survey also showed that the positive aspects of CBPM are that ideas could be shared and overall there is a better understanding of the BPs being modelled. The second part of the problem elaboration consisted of usability field studies with participants from both education and industry using a traditional popular BPM software tool, Enterprise Architect (EA). Whilst several benefits of CBPM were confirmed, several challenges were encountered, particularly with regard to the integration and synchronisation of models. To overcome the problems of CBPM, a framework was developed that allows for co-located CBPM using tablet PCs. The framework includes a developed prototype of the BPMTouch software which runs on tablet PCs, as well as some theoretical aspects of CBPM. The BPMTouch software supports effective and efficient CBPM and the synchronisation of process models since it allows multiple modellers to work together on one BP model, with each modeller using his/her own tablet. If one modeller makes changes to the model, the changes are immediately reflected on the tablets of the other modellers since the changes to the model are updated in real time. Modellers cannot draw on the same model simultaneously, however, everyone can see what the active modeller (active participant with the green flag) is doing. Other participants can then become the active modeller and make changes to the model once the flag has been released and re-allocated. The results from the field studies, industry surveys and usability evaluations were all incorporated into the BPMTouch software tool design and into the aspects of CBPM in order to assist with the process of co-located CBPM using touch technologies. Usability evaluations were carried out in which industry and student participants used BPMTouch to create an integrated model and simultaneously and synchronously create a process model. The evaluations of the BPMTouch prototype revealed that participants prefer this system over traditional BPM software since the BPMTouch removes the need for post modelling integration. The theoretical contribution of the framework consists of aspects proposing that organisations should take the potential benefits and challenges of CBPM into consideration and address the Critical Success Factors (CSFs) before embarking on a CBPM project. These aspects can help with decisions relating to CBPM. The use of this framework can improve the quality of process models, reduce the workload of modellers and in this way increase the success rate of CBPM projects.

- Description: Globally, mobile technology use, particularly the use of mobile phones, is becoming increasingly widespread. One consequence of this growth is mounting interest in using mobile technologies in the public sector, particularly in developing countries, because it is seen as enabling better access to information and services for citizens. Mobile government (m-government), defined as the use of mobile technologies and applications for public sector services, promises to extend access to public services to marginalised sectors of the population and is emerging as a new focus in the ongoing challenge to provide efficient, effective and accessible public services. Though interest in m-government is emerging in the provincial Western Cape Government (WCG) of South Africa, few guidelines exist in the WCG to inform the development of public sector mobile services. This absence impacts on service delivery and the primary objective of this study was to propose a set of guidelines that could guide the prioritisation of citizen facing public sector services for mobile implementation in the Western Cape. The study considered two areas namely, government and user needs. The primary research question was to determine what public sector services citizens need and how these services should be prioritised for mobile delivery in the Western Cape. To address this, three research sub-questions were formulated. The first question aimed to examine conceptions of mobile government. To achieve this a literature study and documentation review was conducted, from which factors influencing service prioritisation emerged. The second research question aimed to identify citizen needs that could inform mobile public sector services in the Western Cape. Thus a survey and interviews were conducted with citizens using the WCG community ICT centres (e-Centres). The third research question aimed to identify factors that impact on the prioritisation of citizen facing public sectors for mobile delivery in the Western Cape. The findings from the literature study, survey and interviews conducted were used to address this research question. The results from the three research sub-questions were triangulated to address the main objective of the study and from this a set of guidelines for prioritising mobile public sector services in the Western Cape was proposed.

- Description: It is the 21st Century and the world is a global village. The development of technology like Information and Communication Technology (ICT) has thus become the dominant means of communication. Education has not been left out of this wave of change. In many countries Information and Communication Technology (ICT) has a clear impact in the development of educational curriculum. This cannot be said about South Africa where huge disparities in terms of ICT related resources still exist. There is a range of uses of ICT in South African schools and it varies according to the economic and social conditions where that school is located. For example, the former Model C schools are well-resourced in terms of computers and access to internet whilst township schools lack these resources. In township schools very few students are exposed to computers due to the limited number of computers and lack of properly qualified educators in the field of ICT. In the Nelson Mandela Bay area township schools only offer CAT (Computer Applications Technology) as an ICT related subject whilst the former Model C schools offer CAT and IT (Information Technology).This treatise attempts to show the digital divide that still exists between a former Model C school and a township school, and the impact it has in quality of education in these schools.
