This thesis explores the potential to unify three emerging disciplines: enterprise engineering, enterprise architecture and enterprise ontology. The current fragmentation that exists in literature on enterprise alignment and design constrains the development and growth of the emerging disciplines. Enterprises need to use a multi-disciplinary approach when they continuously align, design and re-design the enterprise. Although enterprises need to be aligned internally (across various enterprise facets), as well as externally (with the environment), most alignment approaches still focus on business-IT alignment, i.e. aligning the business operations with the information and communication technologies and systems of the enterprise. This study focuses on a popular business-IT alignment approach,called the foundation for execution approach, and its associated artefact, called the operating model. The study acknowledges the theoretical contribution of the operating model to establish the required level of business process integration and standardisation at an enterprise in delivering goods and services to customers. Highlighting the practical problems in selecting an operating model for an enterprise, and more specifically the practical problems of identifying process reuse potential at an enterprise, a thesis statement is formulated: The operating model concept, as part of a business-IT alignment approach, can be enhanced with a process reuse identification framework, when a business-IT alignment contextualisation is used. The study is divided into two research questions. The first research question addresses the current fragmentation that exists in the literature, which impairs reuse of the existing business-IT alignment knowledge base. An inductive literature review develops the Business-IT Alignment Model to provide a common contextualisation for current business-IT alignment approaches. The second research question addresses the practical problems of the operating model regarding the identification of process reuse potential at an enterprise. Applying the newly developed Business-IT Alignment Model as a contextualisation instrument, the study demonstrates the use of design research in developing the Process Reuse Identification Framework. The conclusion after the investigation of the two research questions is that the thesis statement was confirmed, i.e. the operating model concept, as part of a business-IT alignment approach, can be enhanced with a process reuse identification framework, when a business-IT contextualisation is used. / Thesis (PhD)--University of Pretoria, 2013. / Industrial and Systems Engineering / Unrestricted

Enterprise modelling can facilitate the design, analysis, control and construction of contemporary enterprises which can compete in world-wide Product markets. This research involves a systematic study of enterprise modelling with a particular focus on resource modelling in support of the life cycle engineering of enterprise systems. This led to the specification and design of a framework for resource modelling. This framework was conceived to: classify resource types; identify the different functions that resource modelling can support, with respect to different life phases of enterprise systems; clarify the relationship between resource models and other modelling perspectives provide mechanisms which link resource models and other types of models; identify guidelines for the capture of information - on resources, leading to the establishment of a set of resource reference models. The author also designed and implemented a resource modelling tool which conforms to the principles laid down by the framework. This tool realises important aspects of the resource modeffing concepts so defined. Furthermore, two case studies have been carried out. One models a metal cutting environment, and the other is based on an electronics industry problem area. In this way, the feasibility of concepts embodied in the framework and the design of the resource modelling tool has been tested and evaluated. Following a literature survey and preliminary investigation, the CIMOSA enterprise modelling and integration methodology was adopted and extended within this research. Here the resource modelling tool was built by extending SEWOSA (System Engineering Workbench for Open System Architecture) and utilising the CIMBIOSYS (CINI-Building Integrated Open SYStems) integrating infrastructure. The main contributions of the research are that: a framework for resource modelling has been established; means and mechanisms have been proposed, implemented and tested which link and coordinate different modelling perspectives into an unified enterprise model; the mechanisms and resource models generated by this research support each Pfe phase of systems engineering projects and demonstrate benefits by increasing the degree to which the derivation process among models is automated.

This research project has established a new measurement model for User Empowerment as an enabler to Enterprise Systems 1 success. This study was inspired by the reported relationship between Empowerment and improved work outcomes. From this, it was hypothesised that empowering the users of Enterprise Systems during the implementation process would improve the reports of post implementation system success. A new related concept of system oriented User Empowerment was conceived. The outcomes of empowering users (increased worker effectiveness; (increased work satisfaction) conceptually resonates very closely to the outcomes of individual performance, quality of system outputs, goodness of system functionality and, on a broader level, effective use of the system to yield successful business outcomes. These latter outcomes represent the measures of Enterprise Systems success. Thus Empowerment as an independent variable, and Enterprise Systems success as a dependent variable, provided a launching platform for the study. The research model was built upon the existing research into Empowerment as articulated by Spreitzer (Spreitzer, 1996) and Thomas and Velthouse (Thomas & Velthouse, 1990) and its derived systems related construct of User Empowerment, first explored by Doll, Deng and Metts (Doll, Deng, & Metts, 2003). It used a current and validated measure of Enterprise Systems Success as developed by Gable, Sedera and Chan (Gable, Sedera, & Chan, 2003); this measure is a refinement of the Information Systems Success Model of DeLone and McLean (DeLone & McLean, 2002). 2 In order to test the relationships of Empowerment to (Enterprise) System success, the following research sub-problems were explored: * What types of Empowerment are relevant in the Enterprise System context? * Is User Empowerment different from Psychological Empowerment and if so, how? * What is the relationship between Psychological Empowerment and User Empowerment? * How can User Empowerment be measured? * What is the effect of Psychological Empowerment on Enterprise Systems success? * What is the effect of User Empowerment on Enterprise Systems success? This research project was a PhD study funded by the Australian Research Council through an industry linkage program. The industry partner in this project was SAP - the most successful vendor of Enterprise Systems. Although limited in analysis the study spanned across two industry sectors, with two Enterprise Systems (Oracle and SAP). This research was a multimethod study and involved both qualitative and quantitative phases. The multimethod included content analysis, survey, and case study. This research was led by an explorative research strategy and paid considerable attention to analysing each research method in relation to other research methods, and also in relation to the demands of the research problem. A comprehensive literature review established extant definitions and constructs for Psychological Empowerment, User Empowerment and, Enterprise Systems success. The literature review employed a formal qualitative research method, using open coding supported through the use of Nvivo, a Qualitative software package, in order to identify and derive key themes in the referent disciplines. The responses from the email survey of Information Systems researchers, and Enterprise Systems consultants were triangulated with the findings from the categorised literature review on Empowerment. This sub-study utilised WordStat software and the findings were presented at the QualIT conference (Sehgal & Stewart, 2006). Drawing from the existing perspectives on Empowerment a contextbased perspective on Empowerment was proposed by the researcher. From this work, a new working definition of (User) Empowerment was derived. This construct proposed that User Empowerment involved Computer Self-efficacy, Perceived Usefulness, Intrinsic Motivation, User Autonomy, and Problem-solving and Decision support. Psychological Empowerment involves Meaning, Self-determination, Competence, and Impact. The research project then empirically tested the relationship of both Psychological Empowerment and User Empowerment to Enterprise Systems success using a quantitative enquiry. The new User Empowerment construct was statistically tested for validity and reliability. This quantitative study found no statistical evidence for a relationship between Psychological Empowerment and Enterprise Systems success. The study findings suggest significant statistical evidence for a relationship between User Empowerment and Enterprise Systems success. Statistical analysis showed that the construct for User Empowerment was different from the construct of Enterprise Systems success. These relationships held regardless of the level of the user: senior management, operational, end users or technical. This phase of the study was presented at the Americas Conference of Information Systems (Sehgal & Stewart, 2004). This exploratory survey was followed by another industry based case study, which confirmed the results for a different industry sector and different Enterprise System. This latter study was used in an independent confirmatory factor analysis of the Enterprise Systems success measurement which was presented at the Americas Conference on Information Systems (Sehgal & Stewart, 2004) and International Conference on Information Systems (Sedera, Gable, & Chan, 2004) by fellow researchers. This research has demonstrated that User Empowerment, rather than Psychological Empowerment was significantly related to Enterprise Systems Success. The study findings identified potentially significant benefits to the Enterprise System implementing organisations as well as the Enterprise System vendor from empowering Enterprise System users. Of the reported benefits one of the relevant one was improved and positive reports about the implemented Enterprise System. Further, the study highlights the importance of context when measuring a construct such as Empowerment. There are clear practical implications for the research outcomes. These include a recommendation that training programs should ensure that users have a high degree of computer self-efficacy when using the enterprise system. The validated User Empowerment instrument will be utilised as a diagnostic tool for organisational readiness prior to an ES implementation. This would assist in benchmarking the level of empowerment and predicted Enterprise Systems success. Future research will explore the effects of an Enterprise System on the components of User Empowerment as it is conjectured that there is a reciprocal relationship between the system and user attributes of Computer Self-efficacy, Problem-solving Decision Support, and understanding of business logic.

Over the decades, as organizations begin to move globally there has been a sporadic flow of information in their supply chain. Competition today is forcing companies to integrate tightly with their suppliers and customers, in order to reduce the time available to flex the supply chain (SC) (Koh S.C, Saad S, Arunachalam S, 2006). The integration of firms and departments and information is getting more and more complicated. Regardless of enterprise system solutions being introduced as “integrated suites” they have failed to accomplish application and supply chain integration (Themistocleous, M. Irani, Z. O‟Keefe, and R. 2001). Therefore, this thesis aims to explore, gain better understanding and to explain the balance that may occur between the challenges and benefits gained from integrating enterprise resource planning and supply chain management.Our topic of interest could be view from both developers and user perspective. Developer/consultant‟s perspective is based on the viewpoint of those involved in and responsible for developing enterprise solutions. User‟s perspective, this perspective gives insight to how the integration process is perceived by organisations actually using the solutions. We chose the User perspective because we consider the user to be the direct beneficiary of whatever outcome is gotten from both the business solutions and its integration.In order to achieve a purposeful thesis. We decided to use an interpretive perspective which focus on exploring and gaining insight into issues of integrating enterprise system solution. We used both the inductive and the deductive approaches in our research. This would be advantageous due to the nature of our research topic, as there is little existing knowledge about the integration of enterprise systems solution within supply chain and there are lots of literatures related to the enterprise system solutions (ERP and SCM) been observed. The inductive approach would guide us to choose one or a few specific interactions to explore in-depth, while the deductive approach would aid us when making an hypothesis, since we would be collecting ideas about previous research and theories in order to guide us and make comparison.Conclusively, we found that the balance between challenges and benefits of ERP and SCM are unequivocal, as the benefits surpass the challenges and the effect of challenges on organisation‟s benefit is that it prolongs the short term benefit.

Virtual enterprises are increasingly being used as an organizational strategy for meeting customer needs. Potential benefits of virtual enterprises include increased profits, flexibility, increased customer service, better quality, a quicker time to market, and access to larger markets. However, the brokers that organize these ventures face challenges that arise in five key management activities: select partners, develop communication, develop culture, develop trust, and enhance behavior through motivation. A broker?s ability to overcome the problems in these activities determines the degree to which the benefits are achieved. Examples in the literature point to the possibility that interactive relationships exist between the five management activities. Considering all of these possible associations leads to a complex web of relationships that makes it difficult to determine the overall impact of specific improvements. This research investigates the five management activities and defines the primary relationships between them. The primary relationships are used to develop a conceptual model that brokers can apply as a methodology for systematically developing a virtual enterprise and thereby proactively addressing potential problems. In developing the conceptual model, this research utilizes approaches from other disciplines for addressing similar problems. The application of these approaches results in the use of systems engineering concepts to plan and design a virtual enterprise, the development of a partner selection methodology that incorporates ideas from the supplier performance measurement literature, the development of a pre-partner cultural assessment and post-partner cultural development process that are based on ideas found in the literature on mergers, and the use of project management as a means for coordinating the activities in a virtual enterprise. In addition to the preceding contributions, this research provides a comprehensive view of the characteristics of virtual enterprises. Included in these provisions are a detailed definition process and an extension of the literature to establish a typology of virtual enterprises.

Enterprise Resource Planning (ERP) systems are part of information systems on which organisations depend when conducting business. An ERP system offers useful functionality in the smooth running of any organisation. This dissertation investigates the impact of ERP implementation at SASSA North West Regional Office. It highlights problems of the current ERP system by delineating the weaknesses and pitfalls. The relevant literature has been visited and has served as a primary data that adds value to the dissertation. Collation of the relevant data is followed by a discussion of the employee perception of the impact of ERP implementation. The relative lack of research of impact on ERP implementation is the primary impetus of this study. The sample was drawn from SASSA North West Regional Office employees who were cooperative in the execution of the study. As a result of this. the research on the subject has moved beyond the limited confines of ERP implementation to focus more on the impact of the ERP system. ERP system is focused on standardisation and synchronisation of information as a result of improved organizational efficiency, but unfortunately problems with the ERP system can create challenges and dissatisfaction among the end users, resulting in failure to deliver the anticipated benefits. The findings of this study reveal ed that there is de ficiency in the ERP system; employees are worried about data loss when they use the system, find system errors, experience difficulty in expotiing data, and are not satisfied with the quality of output from ERP system. SASSA management should explore opportunity to ensure that the employees are trained to be familiar with the ERP system, improve system reliability, reduce possible system errors, and look at the conclusion and recommendations made in this dissertation. / Thesis (MBA) North-West University, Mafikeng Campus, 2012

This purpose of the research is to investigate the relationship between the implementation of an Enterprise Risk Management (ERM) and corporate governance within the public sector. Furthermore, the study focused on the role of internal audit in ERM implementation as well as the relationship between ERM and risk communication. Questionnaires designed to collect data were e-mailed to risk managers; internal auditors and senior managers. The survey confirmed a positive association between the implementation of an ERM framework and corporate governance as well as risk communication. The majority of respondents further confirmed that corporate governance concerns were the main driving force behind the implementation followed by the impact of HIV/AIDS on their respective organisations. Of those surveyed 38% confirmed that their ERM process is embedded and they have also created the position of chief risk officer or similar. However, it is important to note that the role of internal audit in ERM implementation is not fully integrated.

An investigation into whether the colour red has more impact or leads to common perceptions about the price or value of retail products in advertising. / ABSTRACT Colour is often an important non verbal cue in advertising. Much research has been dedicated to the creative aspects of advertising generally and to factors affecting consumer response in relation to marketing, advertising and pricing. This study looks at the colour red and investigates whether use predominant use of red in sale promotions print advertising is justified on the basis of its ability to impact cognitively or affectively. The study comprises of two experiments, one for awareness and one for price perception and purchase intent. In each experiment, red is compared to other colours in order to establish any significant differences. The second experiment goes further to examine whether the intensity of colour, verbal cues or demographic differences have an impact on the results. The literature review begins with an examination of price theory and the role of sales promotions in organizations. It considers advertising response models with focus on the persuasive hierarchy AIDA model. The impact of colour is then considered along with consumer psychology and behavior as well as theories relating to demographic and cultural responses to colour in advertising. Argument from the sources is then put forward to suggest that research into the effects of colour in advertising is underexplored and that the role of colour in affecting response is complex and is over oversimplifies by advertising practitioners. The research results are presented revealing few significant differences between red and alternative colours for awareness, price perception or purchase intent. The result for awareness is blurred by research limitations, but red does not emerge as a candidate for exacting higher levels of awareness than a number of other colours. In the second experiment, red is found to be inferior to blue in affecting purchase intent. Red at 50% saturation is shown to have a more positive impact on purchase intent that a red hue at full saturation. Demographic splits do not show conclusive results, but it is suggested that a larger sample size would induce a better price perception of red for the black community than for other racial groupings. Discussion and recommendations follow. In this study, red shows no qualities to justify its predominant use in price promotion advertising and more benefit might be obtained for the brand by differentiating through use of alternative colours that may stand out in a sea of red over traditional sale periods. The principle recommendations are, firstly, the need to acquire a deeper understanding of the effect of colour in advertising. In the more complex, competitive global marketplace competition for customer attention is high and the margin of error for irrelevant advertising appeals are low. Secondly, the argument is made for colour usage to be built around long term branding concerns rather than short term requirements for advertising response.
