Despite numerous frameworks and models proposed in the literature, Information Systems (IS) assessment still remains elusive. In addition, little agreement exists on the contribution of the IS function within an organization and on how IS is related to the other organizational dimensions. Frameworks that show the relationship between IS and the organization are in the developmental stage and this work proposes a more comprehensive framework to assist in better understanding the relationship between IS and organizational quality. This research examines two popular IS quality assessment frameworks - Malcolm Baldrige National Quality Award (MBNQA) and Information Systems Assessment (ISA) - and suggests a new framework, IS-MBNQA. This work integrates these two IS quality assessment frameworks into a single comprehensive model that provides a holistic view on how IS quality is interrelated to organizational quality. The existing two IS assessment frameworks attempted to measure IS quality at different levels within an organization. The MBNQA model is the most comprehensive quality framework because it takes an organization wide perspective. On the other hand, ISA employs an IS specific perspective and reflects the relationships of eight major IS success dimensions. ISA is a modified version of DeLone & McLean's model with the inclusion of a success factor for Service Quality. For this study, survey instruments are developed from the MBNQA and ISA frameworks and they are consolidated to allow testing of the single IS-MBNQA framework. Exploratory factor analysis is performed for instrument refinement and confirmatory factor analysis for validity of the models. The instruments developed in this work are utilized as a foundation for identifying the relationships among the dimensions within and between each model. A major contribution of this work is the validation of the 2000 MBNQA model and the extension of existing models/frameworks to better explain the IS contribution to an organization.

This study investigates the impact of multimedia on the effectiveness of information scanning. Information scanning is the act of seeking and receiving a wide variety of special information to develop a thorough understanding of the organization and the environment. The application domain of this study is Executive Support Systems. The experimental task is to identify potential threats and opportunities, a strategic information-scanning activity, based on the information stored in three ESS prototypes. Forty subjects from four organizations participated in the experiment. A random assignment process allocated them into three groups. The control group used the text-based ESS. The first experimental group used the visual multimedia ESS. The second experimental group used the audiovisual multimedia ESS. The experiment was carried out on the sites of the participating organizations. The investigator measured the effectiveness of information scanning based on the number of threats and opportunities each subject identifies. A close-ended questionnaire measured subjects' retention of information. The results of this study support the cognitive-fit theory. The findings indicate that multimedia is not an appropriate presentation format for analytical tasks. Subjects who use text-based ESS identify significantly more threats and opportunities than subjects who use audiovisual multimedia ESS. The cognitive style of subjects does not moderate the impact of multimedia. The results show that the use of multimedia does not necessarily improve retention of information. Further research is needed to determine the most effective combination of text, graphics, animation, video, and sound.

M.Com. (Computer Auditing) / Competence in information technology (IT) is crucial for the professional accountants and most importantly, for information systems (IS) auditors currently practising in the execution of IS audits. The increasing dependence of businesses on computerised information systems gives rise to the need for auditors who possess IT knowledge and skills. This study reports the results of a study that investigates the level of IT knowledge and skills required for an IS auditor in the specific context of audit work in South Africa. Results of this study are based on a literature analysis and on data collected from different IS auditor practitioners. The aim of this study is to: (i) examine the IT knowledge and key areas of expertise required from an IS auditor; (ii) determine the educational qualifications required of an IS auditor; and (iii) evaluate the soft skills required from an IS auditor. This research involves a two-stage empirical study. Firstly, the study carried out a literature survey of IT knowledge and skills. Secondly, structured interviews were conducted with a sample of IS audit practitioners. The findings from this study make three main contributions to the field of IS auditing practice and auditing education. Firstly, the study will help in contributing to a theoretical enhancement of the current level of knowledge in the limited existing literature on IS auditors and the type of knowledge and skills that is required from the professionals to perform their duties effectively and add value to the organisation. Secondly, findings from this study are significant to the standards setters regulating the audit profession, academia designing university courses, and audit practitioners evaluating their own IT knowledge. An important contribution of this study is that the findings would initiate discussion, debate and action that would lead to positive changes in the South African IS auditing profession to ensure that IS auditors are on par with the latest technologies around the world.

M.Inf. / The research study investigates the importance of information as a resource in academic institutions. The study serves to answer questions appertaining to management of information as a resource, such as, what is information resource management? How should information as a resource be managed in academic institutions? How should information be audited? Which stages should be followed in developing information policy? The interrelationships of information as a resource, information auditing and information policy as managerial components are discussed. Information audit and information policy become the major components of management of information as a resource. Information in various enterprises is becoming increasingly recognized as a resource. The study purports to indicate that information as a resource can be managed like other traditional resources such as labour, entrepreneurship, capital and natural resources to use it for competitive advantage. The aims of information audit and information policy are to serve as fundamental development of an information managerial strategy. The information audit enables the information service to pursue the most significant strategic marketing of its information resources. The necessary breadth of information auditing techniques, such as Burk and Horton's "Infomap" are required to fulfill a wide variety of objectives. They analyze the effective methodology for auditing information resource controls and help to identify relevant and accurate information resources for the purpose of learning, teaching and research. The purpose of developing information policy is prompted by the objective of which the information enterprise would successfully like to achieve. It is more appropriate to develop a set of information policies, each of which is concerned with a specific area of operation or focussed on other topics of interest and informational value within the academic institution. At the ultimate end the University of the North is singled out as a model for the development of information policy.

In fulfilment of the requirement for the degree of Doctor of Philosophy in Information Systems. In the Division of Information Systems , School of Economic and Business Sciences. University of Witwatersrand 2017 / This thesis is about how an organization adopted an information system (IS) and the subsequent current use of that system. That is, the relevance of this thesis is premised within the adoption and use of IS research fields. The adoption and use of systems is still a key IS issue as organizations strive to find ways to justify investments while the research issue is in striving to profoundly describe the adoption and use behavior. The thesis employs Human resource information systems (HRIS) as the system under study, with a South African university being the context. HRIS are adopted and used in organizations, including universities, to facilitate human resource functions and practices. The adoption and use of HRIS is often critical to achieving organizational visions and mandates; however, literature in this field is still in its infancy, with no known study conducted with a South African university context. To this point, there was a need to study behavior during HRIS adoption and the subsequent use behavior, in order to inform an efficient and appropriate ongoing use. Existing scholarly HRIS literature focus on either its adoption or its use, but hardly addressing both concurrently. This thesis argues that adoption may inform present use, and therefore, paramount to study both facets, and in the same locale. The study sought to understand how HRIS was adopted as well as understand how it is presently used, in the context of a South African university. The research argument driving the thesis is that HRIS is realized in a multidimensional environment, and thus, there is a need for a framework that may inform both adoption and use dimensions. The framework ought to be cognizant of the contextual determinants which influence both adoption processes and use behavior at varied levels, so that HRIS is adopted and used effectively and efficiently, sensitive to the South African context. To conceptualize the multidimensional framework, the study was underpinned by Upper echelon theory; Social cognitive theory; Technology, organizational and environment framework; and Task-technology fit, as theoretical lenses. Majority of HRIS adoption or use studies take a positivist stance; however, this thesis deemed an interpretivist philosophy as a more appropriate stance to understanding the complexities of adoption iii and use. A qualitative inductive approach using a case study research strategy was the methodology followed. Semi-structured interviews, field observations and institutional documents were ways to collect data. The empirical data were analyzed following thematic analysis and content analysis techniques. Literature and the interpretation of study findings informed the conceptualization of the multidimensional framework for the adoption and use of HRIS. The thesis contributes theoretically by providing a framework that informs adoption and use; practically, the framework may be used by policy and decision makers to improve use and appropriate use of HRIS; Methodologically, the thesis shows how a case study following the interpretive philosophy may be a better alternative to profoundly describe and explain adoption and the use of HRIS; finally, the thesis contributes to context by giving insights unique to South African universities. Keywords: Adoption and use framework, Human resource information systems Interpretive case study, Multidimensional, South African university / GR2018

A research report submitted to the Faculty of Engineering and the built environment, University of the Witwatersrand, in partial fulfilment of the requirements for the degree of Master of Science in Engineering. Johannesburg, 2017 / Construction fragmentation remains a major concern amongst professinals through-out project phases in South Africa.The report identifies fragmentation challenges in the context of integration, collaboration, communication and coordination encountered by professinal teams in construction projects. It also investigates whether the intrinsic properties of the construction projects, namely the project size, clients, project locations and project delivery methods, contribute to fragmentatio challenges experienced by the construction professinals. To accomplish this, the study employs mixed method research by using a qualitative tool to capture the raw data from the participants, and analysing the captured data quatitatively. While the results of the study are derived quantitatively, one could not quantitatively measure fragmentation on integration, collaboration, communication and coordination, i.e the results did not translate to weighted fragmentation. However, there are subtle, but enlightening points from the survey that exposed elements of fragmentation challenges faced by the professional team. While some of these challenges seem to lead to natural solutions, it appears most of the may be solved by implementing building information modelling. / MT2017

This is a case study of a federal bureaucracy and its Information Resource Management (IRM) organization. The Bonneville Power Administration (BPA), a federal power marketing agency and part of the Department of Energy, significantly impacts the western United States. BPA is responsible for developing electric power resources, transmission of electric resources. power conservation programs, and fish and wildlife programs. The focus of the study is the perception of the quality of information supplied to management, assuming that better information makes better decisions. The study uses a pre-experimental research design to evaluate the satisfaction executive and middle management with information they use to make decisions. The study uses both questionnaire and interview methodologies to examine management opinions before the establishment of IRM and two years after the establishment of IRM. Literature on bureaucracy indicates that decision making has limits and processes. Channels of communication, both formal and subformal are used by decision makers to gather information to fill information gaps. The gaps exist because formal channels of information do not supply sufficient information. Consequently, decision makers constantly search for information. There is a great deal of literature addressing IRM and other similar organizations. The technical and operational sides of information management are occasionally conflicting but, adequately addressed. Information assessment and evaluation are approached inadequately.

The household has always been a place of information consumption. While much is known about the modern household as a consumer of information and adopter of information-related technologies, virtually nothing is known about how the household -as a collectivity - processes and manages its information. This research represents the first systematic study of the household as a human information system and presents an understandingtype theory of household information practices. Using dimensional analysis (including theoretical sampling) as proposed by Schatzman (1991), the information practices of eleven households (28 householders) were explored. Each householder completed a questionnaire to identify the information and information-related devices and services used in the household. This was followed by an unstructured group interview that explored the information practices in the household. Analysis of the questionnaires and interviews revealed that within a household it is individual householders who process and manage information. They do so because information has a role in their life, that is, particular information is meaningful for them. Each householder thus devises their own individual information practices, representing the unique way in which a householder comes to live with information. Household information practices are the sum of these individual information practices. They are mediated by two enabling processes - taking charge and negotiating - and nine dimensions of action. Six of the dimensions affect the information practices of individual householders - which are themselves a dimension - while the final two represent, respectively, the consequences of living with and without information. All processes and dimensions operate against, and interact with, a changing structural context of information, technology and society. As a result, each household has a characteristic mode for dealing with information. The centrality of negotiation in developing household information practices indicates that the practices are socially constructed and represent an emergent phenomenon. This, in turn, suggests that the household as an information system is a negotiated order. Insights from the research can be applied to other types of organisations and other aspects of the Information Systems discipline. Areas of further work are identified to expand upon the exploratory nature of this research.

Sharing and exploitation of information resources across a diverse organisation can confer a significant competitive advantage but also can be a substantial challenge in coordinating across structural and specialisation boundaries. This challenge reflects the difficulties traditionally associated with lateral relations, which were recognised by classical organisational theorists but are more pronounced with the emergence of information as a critical resource. Notwithstanding the benefits of information sharing across the organisation, the classical concept of specialisation remains fundamental to organisational theory; thus there is potential for friction between requirements for specialisation and coordination. This research therefore examines information management arrangements to balance specialisation and coordination in a diverse organisation. The research takes advantage of organisational and systems theory literature to appreciate complex information management requirements in terms of differentiation/cohesion and integration/coupling of organisational elements. Information management???s business and technology perspectives define the conceptual framework, within which gaps in the literature are identified and become the focus of the research. The two key research areas are the opportunities enabled by technology for business integration through collaborative decision-making and the management of organisation-wide information technology infrastructure. Collaborative decision-making is an integrating mechanism that can provide balance between specialisation and coordination contingent upon the nature of decision tasks and their organisational context. Propositions associated with an adaptive approach to collaborative decision-making were tested in laboratory experiments, with positive support for the contingency model albeit constrained by individual cognitive variances. Organisations increasingly are adopting centralised approaches to the provision of IT services, with IT governance as an integrating mechanism and a need for multiple business-IT alignments to add value according to the differentiation required by organisational elements. Propositions relating to the adaptation of IT management arrangements based upon organisational characteristics were tested using a multi- iv -discipline approach, which resulted in support for the model although practical difficulties were experienced in the action research component. This research provides a framework for maintaining effective variety of information capabilities commensurate with the diverse organisation???s mission and environment, while also exploiting the synergies and economies of shared information resources for holistic benefits.
