Thesis (MComm)--University of Stellenbosch, 2002. / ENGLISH ABSTRACT: Defence forces around the world are experiencing a period of dynamic change with new force structures being combined with new technologies in an effort to enhance effectiveness. Present day resources and technology available to the modern society, have facilitated the evolution of warfare as a technologically advanced enterprise, with the decided emphasis on the digitisation of the battlefield. With rapid development in the field of battlefield digitisation there is an increasing need to address the important issues and challenges facing the military. In order to meet strategic defence guidelines, it is necessary to integrate the capabilities of defence forces with modern technology. In this regard the South African Defence Force is striving towards the digitisation of the battlefield. This digitisation can potentially satisfy the many requirements set for the Defence Force, in a more timely and cost-effective manner than traditional methods of functioning and training would be able to achieve. Effective situational awareness and command and control structures are essential for any military operation, especially with increasingly complex military demands. Key areas of importance are the collection, dissemination and management of information, which if executed skilfully, will result in forces capable of operating more effectively and with greater flexibility. Decision makers on the battlefield continually suffer from information overload due to the extremely rapid inflow of information. This is likely to worsen with the continued introduction of new information technologies. The technology level of any defence force should therefore be appropriate, driven by usefulness and cost-effectiveness. The digitised battlefield allows for the execution of near realistic military exercises, while conserving material and reducing the detrimental impact on environment and personnel, as is the case with traditional exercises. A key issue of focus is the usability and integration of related technologies within the digital battlefield. Promoting optimal usability through continuous and comprehensive user-based evaluation is crucial and will result in increased human performance through interaction with technology. Optimal usability must be engineered into any product (defined as something produced by means of either human or mechanical work) from the inception of the product's life cycle. Within today's technology orientated society, the digitisation of the battlefield and the usability thereof have become increasingly important issues. Most research has investigated the concepts of battlefield digitisation and usability in isolation, and little co-ordinated effort has been made to integrate digitisation and usability, even though the relation is important and necessary. A study of this nature has not hitherto been conducted within the South African military context. The purpose of this study is to provide a theoretical background of the issues of military digitisation and usability, in order to determine the significance of this relation. This research aims specifically to promote the viewpoint that usability is central to military digitisation, as well as to emphasise the importance of user-centred approaches to system development and utilization. The result will be enhanced human performance and satisfaction when interacting with digital battlefield applications. The theoretical perspective is provided by way of a literature review of the relevant military and usability concepts. Military functioning is discussed, highlighting the importance of situational awareness and effective command and control capabilities. The digitisation in the military is examined with specific reference to Virtual Reality and simulation. An overview of usability (within a human-computer interaction and user-centred design context) and usability evaluation methods are provided. This research was conducted during a military exercise conducted by the South African National Defence Force. A usability inquiry approach was followed with questionnaires distributed to participants involved with the Command and Control Digital Battlefield System. Information was obtained concerning participants' characteristics, likes, dislikes, needs, and understanding of the digital battlefield system. The analyses of the information consisted of descriptive statistics as the research aimed to illustrate the attitudes concerning usability and the digital battlefield. The results provide an understanding of the perceptions of the users regarding the digital battlefield system and its usability. Conclusions are drawn from results obtained and recommendations are made for future research. / AFRIKAANSE OPSOMMING: Moderne weermagte deur die wereld ervaar tans 'n peri ode van dinamiese verandering met nuwe magstrukture wat met nuwe tegnologiee gekombineer word ter bevordering van doeltreffendheid. Die hedendaagse hulpbronne en tegnologie tot die moderne samelewing se beskikking, het meegebring dat oorlogvoering ontwikkel het in 'n tegnologies gevorderde aksie met die klem op gevegsterrein-digitalisering. Die betreding van 'n era van tegnologies gevorderde oorlogvoering met die gepaardgaande snelle ontwikkelings in die veld van gevegsterrein digitalisering, het 'n toenemend groeiende behoefte laat ontstaan vir die indringende aanspreking van belangrike strydvrae en uitdagings wat 'n moderne weermag in die gesig staar.Tiit is noodsaaklik dat die vermoens van weermagte geintegreer word met moderne tegnologie ten einde aan strategiese verdedigingsvereistes te kan voldoen. Die Suid-Afrikaanse Nasionale Weermag het digitalisering van die gevegsterrein ten doel. Sodanige digitalisering kan potensieel die talle vereistes gestel aan 'n weermag op 'n meer tydige en koste-effektiewe wyse bevredig as wat met tradisionele metodes van funksionering en opleiding gedoen kan word. Effektiewe situasionele bewustheid en bevel en beheer strukture, is onontbeerlik in enige militere operasie, veral in die lig van toenemende komplekse eise gestel aan die moderne weermag. Sleutelareas van belang is die insameling, disseminasie en bestuur van inligting, wat as dit met die nodige insig en kundigheid uitgevoer word, aanleiding sal gee tot die verhoogde doeltreffendheid en buigsaamheid van 'n weermag. Die tegnologiese vlak van enige weermag behoort dus toepaslik en bruikbaar te wees, sowel as koste-effektief gedrewe. Die gedigitaliseerde gevegsterrein maak vcorsiening vir die uitvoering van bykans-realistiese militere oefeninge met behoud van material en grootskaalse uitskakeling van die negatiewe invloede op die omgewing en personeel, meer so as wat andersins die geval sou wees met tradisionele oefeninge. 'n Sleutel-aspek is die bruikbaarheid en integrasie van verwante tegnologiee in 'n gedigitaliseerde gevegsterrein. Die bevordering van optimale bruikbaarheid deur aaneenlopende en omvattende gebruikersbaseerde evaluasies, is deurslaggewend en sal lei tot verhoogde gebruiker prestasie betreffende interaksie met tegnologie. Optimale bruikbaarheid moet reeds vanaf die aanvang van 'n produk se lewenssiklus, bewerkstellig word. In die hedendaagse tegnologie-gebaseerde moderne same lewing, het digitalisering van die gevegsterrein en die bruikbaarheid daarvan, toenemend belangrik geword. In die meeste navorsmg word gevegsterrein digitalisering, asook bruikbaarheid, afsonderlik ondersoek, onafgesien van die belangrike verwantskap daartussen, en slegs geringe gekoordineerde pogings is van stapel gestuur om digitalisering en bruikbaarheid te integreer. In die Suid-Afrikaanse rnilitere konteks is so 'n studie nog nie uitgevoer nie en derhalwe het hierdie studie ten doel om 'n teoretiese agtergrond te voorsien van militere digitalisering- en bruikbaarheidskwessies, asook die vasstelling van die verwantskap daartussen. Hierdie navorsing het spesifiek ten doel om die standpunt te bevorder dat bruikbaarheid sentraal staan tot militere digitalisering sowel as om die gebruiker-gebaseerde benadering tot sisteem ontwikkeling en benutbaarheid, te bevorder. Die resultaat sal verhoogde gebruikerprestasie en tevredenheid wees wanneer interaksie met gedigitaliseerde gevegsterrein toepassings plaasvind. Die teoretiese perspektief word voorsien deur 'n literatuur-oorsig van die relevante rnilitere- en bruikbaarheidskonsepte. Militere funksionering word bespreek met beklemtoning van die belang van situasionele bewustheid en doeltreffende bevel en beheer vermoens, Militere digitalisering word ondersoek met spesifieke verwysing na virtuele realiteit en simulasie. 'n Oorsig van bruikbaarheid (binne die konteks van mens-rekenaar interaksie en gebruikersgeorienteerde ontwerp) sowel as bruikbaarheidsevaluasie-metodes word voorsien. Hierdie navorsing is uitgevoer tydens 'n militere oefening van die Suid-Afrikaanse Nasionale Weermag. 'n Bruikbaarheidsondersoek-benadering is gevolg deur vraelyste uit te deel aan die deelnemers wat betrokke was by die gedigitaliseerde bevel en beheer stelsel. Informasie is ingewin betreffende die deelnemers se kenmerke, persepsies, voorkeure, afkeure, behoeftes en begrip van die gedigitaliseerde gevegsterrein-stelsel. Die analise van die informasie het beskrywende statistieke behels omdat die navorsing ten doe I gehad het om ingesteldhede betreffende bruikbaarheid en die gedigitaliseerde gevegsterrein, uit te lig. Die resultate voorsien 'n begrip van die persepsies van die gebruikers rakende die gedigitaliseerde gevegsterrein, en die bruikbaarheid daarvan. Gevolgtrekkings word gemaak vanuit die resultate verkry en aanbevelings word voorsien vir verdere toekomstige navorsing.

The South African Police Service (SAPS) as a constituent part of the public service was established to deliver a specific category of services to the public. These services have to conform to requirements that are prescribed by various legislative provisions to promote effective and efficient delivery of public services. The implications of these provisions that are pursued by the study firstly, refer to the emphasis of government on the enhancement of public service delivery, with due consideration given to cost effectiveness and efficiency. Secondly, it refers to government's realisation of the important impact of education, development and training (EDT) on the competency of public service officials with an emphasis on the utilisation of information technology to enhance the effectiveness of EDT. Consequently, the study explores the viability of the utilisation of information technology as a measure to assist EDT interventions within the SAPS of the Eastern Cape Province to equip members of the institution to better fulfil their functions and duties. In this respect the study commenced to ascertain the levels of computer literacy of role-players, access to the appropriate facilities and what the general attitude in the organisation would be towards the utilisation of such an intervention. It was found that the computer literacy levels of role-players may be perceived as a problematic issue in this regard. However, access to suitable facilities was found to be more than sufficient for this intention. Furthermore, role-players agreed that information technology could be optimally applied in the EC SAPS for the mentioned use, thereby portraying an optimistic attitude towards the use thereof to harmonise EDT in the SAPS. The aim of the study has been to develop a model that will incorporate the use of information technology, given the strengths and weaknesses of the SAPS to enhance EDT and learning in the organization.

This case study examines the James 1:27 Trust as an information, communication and technology response to the plight of orphans and vulnerable children within the context of an HIV and AIDS epidemic. The James 1:27 Trust demonstrates how social networks can be mobilized in support of children at risk. The use of business information and management systems to administer concepts such as “virtual adoption” is deemed an important innovative contribution. The James 1:27 Trust and its model is studied as a contributor in finding solutions to scale and multiply levels of care by community and faith-based organisations to orphans and vulnerable children. The James 1:27 Trust is located at the Innovation Hub in Pretoria, Africa’s first internationally accredited science park. / Social Work / M.A. (Social Behaviour in HIV/AIDS))

Thesis (MA (Industrial Psychology))--University of Stellenbosch, 2008. / The survival of an organisation in a global competitive business environment depends on its survival skills (e.g. adaptability, flexibility and innovativeness), which is situated within its human resources. Hence, the recruitment function’s role is critical, since it is responsible for the procurement of key intellectual capital that could equip the organisation with a competitive advantage. However, against the accelerated growth of the Internet combined with global competition, traditional recruitment methods are increasingly failing to rise to the challenge of securing key intellectual capital, due to being too time consuming and expensive. Consequently, organisations are progressively turning to online recruitment (which does not refer to one specific technique, but rather several different Internet tools that can be employed as a recruitment method, such as organisational websites, specialised job sites, media websites or newsgroups). However, the presence of an organisational website that advertises vacancies is not sufficient to guarantee its success as a recruitment method. Hence, it is vital to gain an understanding of website recruitment, as well as how to maximise the website’s effectiveness and ability to facilitate successful online applicant behaviour (SOAB), in order to harness its full potential as a recruitment method, able to secure key intellectual capital. For the purpose of this study, SOAB refers to potential applicants (i.e. job seekers entering an organisational website in search of employment opportunities) being able to browse the website without any difficulty and obtain relevant and sufficient information concerning the organisation and its listed vacancies. In addition to enabling potential applicants to assess whether he/she will be able to fit, perform and accelerate in the work climate and culture of the organisation (i.e. decide whether he/she would like to work for the organisation), a website that facilitates SOAB, should also enable potential applicants to contact the organisation to address additional information needs. In essence, this study comprises of three phases and centres on the identification of website content- and usability design benchmarks that should contribute to a website’s ability to facilitate SOAB. By means of a comprehensive literature review, it is argued that the content- and usability design are vital contributing factors to a website’s ability to facilitate SOAB. It is also proposed that the effectiveness of the website as a recruitment method is, to a certain degree, linked to the effectiveness of the alignment of an organisation’s online recruitment strategy with the five stages of potential applicants’ job decision-making process (i.e. the recognition of an employment need, search for career related information, evaluation of career alternatives, identification and acceptance of employment and post-choice evaluation). Phase one, entails the identification of website content- and usability design benchmarks and culminates with the development of the Website Benchmarks Checklist. Phase two, which constitutes the overall purpose of this study, entails an audit of the sample of the ‘best’ SA employers’ (drawn from a survey conducted by the Corporate Research Foundation, 2005) websites. The primary aim is to determine the extent to which the sample’s website design incorporates the identified benchmarks. However, the quality of potential applicants’ interaction with a website (i.e. informative content being communicated in an effective, efficient and satisfactory manner), greatly influences their perception of the organisation’s image, its attractiveness as an employer, as well as their intention to pursue employment within the organisation. Hence, the third phase of the study entails the subjective evaluation of three websites (selected from the audited sample), by a sample of potential applicants. Throughout the study, the empirical tests conducted were descriptive in nature and utilised survey research methods to acquire the required data, related to the specified goals and objectives that encapsulate the aim and purpose of this study. The results obtained provided valuable insight into website design benchmarks that should assist potential applicants in their job decision-making process, increase a website’s ability to facilitate SOAB and maximise its effectiveness as a recruitment method responsible for securing key intellectual capital. In addition to revealing that the majority of the sample employs its website as a recruitment method, the audit results also indicated that although a high level of adherence existed concerning the sample’s incorporation of the usability design benchmarks. However, a notable difference that ranged from very little to relatively high existed with regards to the extent to which the sample’s website design adhered to the content design benchmarks. The subjective evaluation of the three websites by potential applicants revealed that in addition to being critical contributors to the quality of their interaction with a website, the content- and usability design also had a profound impact on their assessment of the websites. Finally, the results also showed that a similarity existed between potential applicants’ subjective evaluation and the extent to which the design of the three websites adhered to the recommended benchmarks (audit results).

The support and promotion of public Technical and Vocational Education and Training (TVET) Colleges is fundamental in addressing South Africa’s intermediate-level and artisanal skills as shortages in these areas contribute to considerable unemployment in South Africa. These institutions have been earmarked by the South African government for extensive growth. Therefore, efficient and effective management and accurate decision-making within these institutions are essential. The evaluation of the management information systems (MISs) within these institutions, which provide data and information to inform institutional short-term and long-term management decision-making and day-to-day operations, should take place on a regular basis to so enhance the reliability and accuracy of the data and information. The problem is that no evidence of a methodology (artefact) for the evaluation of MISs at public TVET Colleges in South Africa could be found in the literature. Therefore, the rationale for this study is to develop a methodology for the evaluation of MISs at public TVET Colleges in South Africa. Hence the main research question for the study was formulated as: What are the components that constitute a methodology for the evaluation of a MIS at a public TVET College in South Africa? The study was conducted according to a design science paradigm. Design science is underpinned by a pragmatic philosophical paradigm which considers thought as a tool for prediction, problem solving and action. The Design Science Research Process (DSRP) model informed the research process utilised to develop the artefact for this problem centred initiated study. The iterated activities of the DSRP model which include: design, demonstrate, evaluate and and communicate, contributed to the refinement of the methodology (artefact). The artefact mainly underwent experimental evaluation to demonstrate its applicability. The methodology (artefact) was empirically evaluated at three cluster-random selected public TVET Colleges after all colleges, with similar MIS maturity levels, were clustered into groups.The study contributed to the extant knowledge base of: theory building, on different levels. The main theoretical contribution is the final evaluated methodology (DSR artefact) which enables IT practitioners and MIS managers at public TVET Colleges in South Africa to evaluate their MISs on a regular basis. The methodology (artefact) presents a theory for design and action which satisfies the conditions of importance, parsimony and novelty on a micro-level. The study furthermore contributed to the extant literature on the theory of MIS success evaluation by contributing to theory on the measurement of MIS success constructs and measuring of the relationships between the constructs. Another theoretical contribution is the innovative evidence-based method by which the public TVET Colleges were clustered. The clustering method was used to ensure a more rigorous sample selection technique than purposive or convenient sample selection of cases and is generalisable to other knowledge domain contexts. The research study furthermore produced results of interest to both technology-focused and management-focused audiences. For technology-focused audiences the processes by which the artefact was constructed and evaluated are described, thus establishing repeatability of the study and building the knowledge base for further research extensions by future design science researchers. The rigour of the artefact design process was complemented by a thorough presentation of the experimental design of the artefact’s field test in three public TVET College environments which provides sufficient detail for management audiences to determine if sufficient organisational resources exist for utilisation of the artefact. / Information Science / Ph.

The relevance of this thesis is in addressing information systems business leadership HRIS use issues.The thesis explains acceptance and use issues central to Human Resource Information Systems (HRIS) within South African State Owned Agencies (SOAs). Organisations typically deploy HRIS with a view to automate Human Resource (HR) service delivery and administrative functions. Among other values, HRIS produces useful data and information which optimises HR operations and improves decision-making. However, the use of HRIS, notably within SOAs, is poorly understood owing to inadequate literature and contextualised studies. Despite the tremendous amount of investment into such systems, SOAs continuously identify emerging challenges and issues pertinent to HR operations and administration. For instance, despite HRIS automation, job applications and recruitment are still manually processed, which means that the costly implemented HRIS is not effectively used, and is thus underutilised. The burning questions for business leadership remain - why is HRIS not optimally utilised given significant organisational investment on such systems, and the mixed return-on-investments? The other question relates to what the level of acceptance is and actual use of these HR systems. There is also a need to determine to what extent do these systems enable or improve the delivery of human resource services and administration. Moreover, what influences the use of HRIS? Previous literature and organisational practice inadequately addresses these questions. This thesis, therefore, addresses these key issues to bridge these preceding knowledge gaps. In order to explain the use and subsequent effective use of HRIS, the study triangulated three theories as theoretical lenses. These theories are the Unified Theory of Acceptance and Use of Technology (UTAUT), Self Determination Theory (SDT), and the Representation Theory (RT). These theories are employed to explore and explain the individual use, and subsequent effective use of HRIS. In this respect, the ontological stance for this thesis is that reality is objective. Thus, the study followed a positivist research paradigm, whilst the research the approach was deductive. A survey research strategy was employed during the study to obtain primary data. Survey participants included executives and individuals from speciality units e.g. HR, Finance, Supply Chain, Support departments (including IT and Help Desks) as well as other HRIS users. Participants were drawn from various South African SOAs. Structural equation modelling and hypothesis testing show that there are myriad of determinants influencing use and effective use of HRIS. The results further show that certain constructs are inconsistent with the existing literature. Nevertheless, this inconsistency speaks to the unique South African SOA contexts. The outcome of the study is a model which theoretically and practically explains those factors which must be considered to effectively use and utilise HRIS. That is, the theoretical, practical, methodological, and contextual contributions of the thesis is in explaining the determinants which are significant for effective use of HRIS. / Centre for Business Manangement / D.B.L.
