    On improving the understanding of software requirements by clients
    (2016) Wing, Jeanette Wendy; Andrew, Theophilus Nethiekreethum; Petkov, Doncho
    Motivated by the literature regarding the need for further research on client participation in software development, a systemic framework for the understanding of client requirements in Information System development projects is developed. This systemic framework is particularly relevant for project contexts characterized by diversity of stakeholder values and complexity. To address this complexity, research led to the selection of methods from three systems methodologies and the conclusion for the need to mix them in the process of requirements understanding by clients. The mixing of methods from various methodologies is justified through the principles of Critical Systems Practice, and the process of their use is guided by Action Design Research. In spite of the strong research tradition associated with Soft Systems Methodology and the growing interest in the Work System Method, the level of use of these by practitioners is not high because complex project situations require harnessing of the strengths of more than one methodology. The proposed framework also includes a third system methodology Critical Systems Heuristics. This study demonstrated how the meta-methodology Critical Systems Practice is applied in justifying the selection and the mix of methods from the above three methodologies in the proposed framework. The principles of design science were applied, where the framework is the design artifact that is developed. Action Research was used to guide evaluation of the framework in the pilot study. The framework was applied in a pilot study to the understanding of the management of a Wellness Centre which operates within the Kenneth Gardens Housing Estate, through action research. As a result of the pilot study some modifications were made to the framework and the process of its implementation. The modified framework was applied in a further main study concerning the management of the Kenneth Gardens Housing Estate which has a broader context than the pilot study. The contribution of this research to the field of Information Systems is both theoretical and practical. One theoretical contribution is provision of a framework for clearer understanding of software requirements by clients. The second theoretical contribution is that Action Design Research is enhanced by adding proper justification for the methods included in the framework through the application of Critical Systems Thinking and Critical Systems Practice. The practical contribution is through the demonstration of Action Design Research being applied to a real-world problem in both the pilot and the main study.

    A model using ICT adoption and training to improve the research productivity of academics
    (2015) Basak, Sujit Kumar; Govender, Desmond Wesley; Garbharran, Hari Lall
    Research productivity is one of the core functions of a university and it plays a crucial role for a nation to develop and find its standing in our global world. This study examined the effect of ICT adoption and training on the research productivity of university academics. Much research has been done on using technology in research with a view to increase productivity. However, hardly any research could be found on the use of ICT combined with ICT training with a view to increase research productivity. This study addressed this gap in the literature. The study sought to design a model that can increase research productivity of academics while optimizing ICT adoption and training effects. The study was conducted at four public universities in KwaZulu-Natal, South Africa, whilst the part of the study on ICT training was conducted at one of the four universities. This study was conducted both in the form of a survey of 103 university academics and in the form of experimental sessions, where the use of ICT (EndNote, NVivo, AMOS, SPSS, and Turnitin) with training was used for research, the use of ICT without training was used for research and, finally, a session where a manual system (without using research software/tools and training) was used for research. The overall aim of the study was to investigate and design a model for the increase in research productivity of academics in universities after having adopted ICTs. The final results of the research revealed that the use of ICT tools (EndNote, NVivo, AMOS, SPSS, and Turnitin) with training increases research productivity as compared to using ICT tools without training, and/or using a manual system (without using research software/tools and training). A statistically proven model is recommended with a view to increase research productivity of academics.

    Program management practices in context of Scrum : a case study of two South African software development SMMEs
    (2015) Singh, Alveen; Nepal, Thiruthlall; Swechurran, Kosheek
    Agile approaches have proliferated within the software development arena over the past decade. Derived mainly from Lean manufacturing principles, agile planning and control mechanisms appear minimal and fluid when compared to more traditional software engineering approaches. Scrum ranks among the more popular permutations of agile. Contemporary literature represents a rich source of contributions for agile in areas such as practice guidelines, experience reports, and methodology tailoring; but the vast majority of these publications focus on the individual project level only, leaving much uncertainty and persistent questions in the multi-project space. Questions have recently been raised, by both academics and practitioners alike, concerning the ability of Scrum to scale from the individual project level to the multi-project space. Program management is an area encompassing practice and research areas concerned mainly with harmonizing the existence of competing simultaneous projects. Existing literature on program management essentially perceives projects as endeavours that can be carefully planned at the outset, and controlled in accordance with strong emphasis placed on economic and schedule considerations. This complexion seems to be mostly a result of well-established and ingrained management frameworks like Project Management Institute (PMI), and is largely at odds with emerging practices like Scrum. This disparity represents a gap in the literature and supports the need for deeper exploration. The conduit for this exploration was found in two South African software development small to medium sized enterprises (SMMEs) practicing Scrum. The practical realities and constraints faced by these SMMEs elicited the need for more dynamic program management practices in support of their quest to maximize usage of limited resources. This thesis examines these practices with the aim of providing new insights into the program management discourse in the context of Scrum software development environments. The research approach is qualitative and interpretive in nature. The in-depth exploratory case study research employed the two software SMMEs as units of analysis. Traditional ethnographic techniques were commissioned alongside minimal researcher participation in project activities. Activity Theory honed the data analysis effort and helped to unearth the interrelationships between SMME characteristics, program management practices, and Scrum software development. The results of the data analysis are further refined and fashioned into eleven knowledge areas that represent containers of program management practices. This is the product of thematic analysis of literature and data generated from fieldwork. Seeing as the observed practices were highly dynamic in nature, concept analysis provided a mechanism by which to depict them as snapshots in time. As a theoretical contribution, proposed frameworks were crafted to show how program management practices might be understood in the context of organizations striving towards agile implementation. Furthermore, representations of the mutually influential interfaces of SMME characteristics and Scrum techniques that initiate the observed fluid nature of program management practices, are brought to the fore.
