- Description: An overview of the literature indicates that there is a real and pressing need to explore the concept of adverse impact in more detail. The Employment Equity Act of 1998 prioritises the issue of group representivity in staff selection and although there are merits in enforcing an Affirmative Action policy, an objective assessment of the inherent requirements of job applicants is still a constitutional and procedural outcome. There is no simple mechanism that can be used to determine the manifestation of adverse impact. However, evidence thereof can be most useful in securing fairness in selection and employment decisions. There is a distinct need to examine the matter of adverse impact and its implications in the South African context. South Africa is confronted with a labour force that is growing dramatically and changing significantly. The demographic trends in our dynamically changing labour markets are likely to amplify skill and ability differences between the resulting contradictory goals of equal opportunity based on individual merit and equal employment results for subgroups of populations. Three selection strategies of a communications company were used as a basis for the assessment of adverse impact. The total population of the Call Centre selection strategy was 150. Seven instruments and measures were utilised in the study, namely, a job analysis, pre-screening exercise, psychometric ability tests, role-play simulation, structured interview, job compatibility questionnaire and a performance evaluation. The total population of the Operator Services selection strategy was 139. Five psychometric instruments were utilised in the study. The total population of the Female Leadership Development Programme selection strategy was 471. Three psychometric instruments were utilised in the study. The Adverse Impact Model was applied to each of the aforementioned strategies. In terms of the definition, adverse impact exists if the selection ratio associated with a particular passing score on a test for one sub-group of job applicants is less than 4/5th’s or 80% of the selection ration for the largest sub-group of applicants. 13 The results of the study indicate that adverse impact occurred in the following instances. In the Call Centre selection strategy, there was evidence of adverse impact in the racial analysis in the ability testing stage. There was also evidence of adverse impact in the gender analysis during this stage. There was no evidence of adverse impact in either the racial or gender analyses during the interview stage. There was no evidence of adverse impact in the racial analysis during the appointment stage. There was however evidence of adverse impact in the gender analysis during the appointment stage. The Female Leadership Development Programme selection strategy revealed evidence of adverse impact in the racial analysis during the appointment stage. The Operator Services selection strategy revealed an adverse impact in both the racial and gender analyses during the testing stage. The issue of adverse impact is obviously controversial. However, data obtained from this process will provide for informative analysis.

- Description: Due to the continual increase in competitive pressure from international organisations, it has become necessary to assess the degree of transformational change within South African organisations to overcome the effect of global forces. Transformation was investigated in terms of organizational restructuring and the various work designs that are utilised by organisations to deal with the effect of global forces. To examine the main problem, three sub-problems were identified. The first sub-problem that had been identified dealt with the extent of which global forces impacted on the business environment. It was investigated by evaluating various economic, technological and sociopolitical forces. From the results it may be concluded that global forces have a large impact on the local business environment. The second sub-problem looked at the degree to which work designs assisted organisations to manage the effect of global forces. It was evident that the flexible types of work designs were more readily utilised to optimise productivity and employee moral. Finally, the third sub-problem investigated the various structures that organisations could adopt to deal with the effect of global forces. Organisational structures were analysed in terms of customer orientation, fulfilment of company objectives and the types of structures that are used within organisations. The results showed that 75% of the sample population believed that their organisational structures co-ordinated all activities within their organisations. Feedback on the type of structures that were used by organisations revealed that various types are being used.

- Description: The censorship of popular music in South Africa during the 1980s severely affected South African musicians. The apartheid government was directly involved in centralized state censorship by means of the Directorate of Publications, while the South African Broadcasting Corporation exercised government censorship at the level of airplay. Others who assisted state censorship included religious and cultural interest groups. State censorship in turn put pressure on record companies, musicians and others to practice self-censorship. Many musicians who overtly sang about taboo topics or who used controversial language subsequently experienced censorship in different forms, including police harassment. Musicians were also subject to anti-apartheid forms of censorship,such as the United Nations endorsed cultural boycott. Not all instances of censorship were overtly political, but they were always framed by, and took place within, a repressive legal-political system. This thesis found that despite the state's attempt to maintain its hegemony, musicians sought ways of overcoming censorship practices. It is argued that the ensuing struggle cannot be conceived of in simple binary terms. The works of Antonio Gramsci, Michel Foucault and Pierre Bourdieu, in particular, are applied to the South African context in exploring the localized nuances of the cultural struggle over music censorship. It is argued that fragmented resistance to censorship arose out of the very censorship structures that attempted to silence musicians. Textual analysis brought to light that resistance took various forms including songs with provocative lyrics and titles, and more subtle means of bypassing censorship, including the use of symbolism, camouflaged lyrics, satire and crossover performance. Musicians were faced with the challenge of bypassing censors yet nevertheless conveying their message to an audience. The most successful cases negotiated censorial practices while getting an apparent message across to a wide audience. Broader forms of resistance were also explored, including opposition through live performance, counter-hegemonic information on record covers, resistance from exile, alignment with political organizations and legal challenges to state censorship. In addition, some record companies developed strategies of resistance to censorship. The many innovative practices outlined in this thesis demonstrate that even in the context of constraint, resistance is possible. Despite censorship, South African musicians were able to express themselves through approaching their music in an innovative way.

- Description: The cable manufacturing industry may not be well known to some people, yet people’s very lives depend on products and services it produces. Today people live in a highly technological or digital world where most of the technology used by society has at least one electrical cable in it or is connected to a countrywide electrical or communications network through electrical cables in order to work. Well trained and experienced corporate and business leaders recognize the importance of lean supply chain and of being closer to one’s business suppliers for efficient running of the business. Like in all other countries where these industries exist, it is vital that the cable manufacturing industry survives and prospers in South Africa, for the benefit of South African telecommunications, electricity suppliers, computer networks and many more industries. However, today there are almost no boundaries in business owing to globalization which enhances free trade. The business environment is changing and there is fierce competition amongst international rivals. What happens then when customers are not happy with low quality products of one supplier? Would they not leave that supplier and look to the competition in order to get good quality products at reasonable prices? Of course they would. Consequently such a supplier would lose market share and ultimately be forced out of business. This research investigates the shortcomings in terms of the implementation of the principles of total quality and technology management in the cable manufacturing industry. It identifies the internationally recognised principles in the fields of total quality management and technology management as a means of enhancing a competitive advantage. Training and development are identified as extremely important supporting mechanisms which should be done professionally for the best results in the implementation of total quality and technology management principles. Finally, suggestions and recommendations based on best management practice are made.

- Description: The research problem in this study was to analyse how the new constitutional, legal and political arrangements have influenced public policy-making in the department of labour with specific reference to the Employment Equity Act. To achieve this objective a theory for analysing policy–making process was presented. Corporatist theory is based on the following assumptions: Public policy is shaped by interaction between the state and interest groups. The state licences behaviour of interested organizations by attributing public status to them Policy-making is based on interest groups bargaining across a broad range of issues. The groups are functionally interdependent to enhance social stability. The groups use consensus in making decisions. Decision-making is centralised, it is done by leaders. The groups are bureaucratic in organization. The groups must be recorgnised by the state so that they can be allowed representation. The research questions that arise are: (1) Who sets the agenda for policy formulation? (2) How is the policy formulated? (3) how are the decisions taken? (4) How is the policy implemented? (5) How is the policy monitored? The objective of this study analyse how constitutional, legal and political changes have influenced public policy formulation in the Department of Labour with specific reference to the Employment Equity Act. Policy–making processes in the South African arena and factors that led to the promulgation of Employment Equity Act were discussed. This study was a qualitative design. Purposive sampling was used in the selection of five participants who were interviewed. All interviews were transcribed verbatim. Data was analysed as described by Rubin and Rubin (1995:260) The result negated some of the assumptions of corporatist theory and others concurred with the theory. The findings of the study revealed that policy formulation in the Department of Labour is as a result of constitutional, and international conventions obligations. The findings further revealed that policy-information is institutionalised and there are competing interests due to divergent ideological orientations, different social backgrounds; racial differences; different; political beliefs; different class background; different historical backgrounds, and gender differences. (v) The formulation of the act was also characterised by advocacy, adversarism, stereotyping, alliances and consensus. These organisations. were bureaucratic and decisions were centralised. This study recommended a theory and the theory postulates that “public policy is the product of the social, economic, political, cultural, technolergical, and natural conditions of a given society in a particular epoch or period in the historical development of the particular nation or society and is influenced by dominant national and international forces and these influences may be cultural, economically, social, politically, technological, and type and system of government.

- Description: This study is a contribution to the ongoing debate concerning the role and involvement of foreign donor entities in the processes of transforming and creating viable and sustainable municipal entities in South Africa. The discussion particularly focuses on the relationship between the donor community and the Department of Provincial and Local Government (DPLG) and how this relationship has been nurtured, coordinated and managed. The study acknowledges the challenges pertaining to local government transformation and the role and mandate assigned to the DPLG by the South African Constitution and the Presidential Coordinating Council (PCC) for it to facilitate the creation of developmental local government. In discussing this, consideration is given to capacity and resource constraints within the Department, which necessitate that it collaborates closely with other stakeholders, particularly donors, in seeking to augment its resource base and capacity. The Department's lack of capacity is further complicated by the various pieces of legislation, which have a serious bearing on how municipalities have to work - irrespective of their capacity and resources limitations. The research also focuses on how this relationship, between the DPLG and foreign aid donors working in the local government sector, is coordinated and managed. From evidence gathered and interviews conducted, the conclusion is drawn that there is much room for the DPLG to improve and strategically focus its interaction with donors as informed by its mandate and strategic priorities. Proposals, which entail development of donor management guidelines, setting up of a donor coordination unit within DPLG, the improvement of the understanding of donor work politics and modalities among DPLG officials, etc., are made.

- Description: The main problem of this study was to assess the communication strategies used by GIRSS to achieve organisational goals. To address this problem, a theoretical study was undertaken to identify the communication strategies used in organisations. The theoretical guidelines for effective communication were integrated into a communication model, which consisted of the following components: · The establishment of organisational communication structures; · The selection of appropriate communication media; IV · The management of communication barriers; and · Addressing the challenges in organisational communication. Based on the model, a survey questionnaire was developed to assess the extent to which GIRSS made use of these strategies. The questionnaire was administered to both managers and non-managers in the organisation. Due to the distance between South Africa and China, the questionnaire was administered via e-mail. The empirical results revealed that some of the theoretical guidelines were followed, but there was room for improvement in terms of communication strategies used at GIRSS. Specifically it was found that many barriers existed as a result of status and other differences, which influenced communication in the organisation. Communication in organisations is very important as it contributes to goal attainment, satisfaction, cooperation and problem-solving. Communication is a skill that can be learned, and managers as well as employees should consider the results of the study to initiate changes to the communication strategies used in the organization.

- Description: The development of conservation and management programs for an animal population relies on a knowledge of the number of individuals in an area. In order to achieve reliable estimates, precise and accurate techniques for estimating population densities are needed. This study compared the use of direct and indirect methods of estimating kudu (Trage/aphus strepsiceras), bush buck (Trage/aphus scriptus), common duiker (Sy/vicapra grimmia), and blue duiker (Philantamba manticala) densities on Shamwari Game Reserve in the Eastern Cape Province, South Africa. These species prefer habitats of dense forest and bush for concealment and are therefore not easily counted in open areas. Herein direct observation counts were compared to indirect sampling via pellet group counts (clearance plots, line transects, variable-width transects, and strip transects). Clearance plots were examined every 2 weeks, while all other methods were conducted seasonally, from August 2002 until August 2003. The strip transect method provided the lowest density estimates (animals per hal ranging from 0.001 for bushbuck to 0.025 for common duiker, while direct observations yielded the highest estimates, ranging from 0.804 for bush buck to 4.692 for kudu. Also, a validation of methods was performed against a known population of kudu during which the DISTANCE method yielded the most accurate results, with an estimated density of 0.261 that was within the actual density of 0.246 to 0.282. In addition, the DISTANCE method was compared to helicopter counts ofkudu and its estimates were found to be approximately 2.6 times greater than the helicopter count results. When the assessment of the methods was made, the cost, manpower and effort requirements, coefficient of variation, and performance against a known population for each method were taken into consideration. Overall, the DISTANCE method performed the best with low cost, minimal manpower and effort requirements, and low coefficient of variation. On Shamwari Game Reserve, the DISTANCE method estimated 0.300 kudu, 0.108 bushbuck, 0.387 common duiker, and 0.028 blue duiker per ha, which, when extrapolated to the total number of animals present within subtropical thicket habitat, estimated 1973 kudu, 710 bush buck, 2545 common duiker, and 184 blue duiker.

- Description: This study set out to examine whether the Eastern Cape Tourism Board (ECTB) had the capability to cope with change. The tourism industry is very dynamic and for the organization to survive, it must be able to adapt itself in a constantly changing environment. The research question was derived from a study done by Human and Horwitz (1992), in which they examined how South African companies cope with change. They developed a model and a questionnaire to measure the capabilities of coping with change. Their model and questionnaire were based on the following four dimensions: strategic orientation, control orientation, social focus and institutional focus. This model classified organizations into four types, namely: the Boardroom organization, the Technocracy organization, the Hardhat organization as well as the Missionary organization. These typologies are discussed in Chapter 2. A modified version of the Human and Horwitz questionnaire was used to conduct this research. The original questionnaire has 32 items, and the questionnaire used in this study has the same number of items. The modification was done to nine questions, to ensure that they were of specific relevance to the organization being researched. The questions were slightly modified taking care to ensure that they still fit within the original dimensions measured by Human and Horwitz (1992). The questionnaires were distributed within the organization, particularly to those employees in the Tourism section, as the organization also had a Conservation section. The Conservation section was excluded due to the fact that a policy decision had already been taken to separate the two sections, thereby creating two organizations. When the questionnaires were returned, they were analyzed using 'Statistica' , a computerized statistics program. The results showed that the ECTB does not have the capability to cope with change as it lacked the critical strategic orientation that Human and Horwitz (1992) suggest is a key requirement for coping. The profile of the organization showed that the ECTB could be classified as primarily being a Technocracy organization, and secondarily a 'Hardhat' organization. (See details in Chapter 4). Human and Horwitz (1992) suggest that an organization to be able to cope with change, must be a 'hybrid' of these four types. The implications of these results suggest that the organization is lacking in the dynamism brought about by having a strategic orientation. Human and Horwitz argue that the profile of an organization coping well with change should show a 'balance' in terms of orientation (strategic orientation and control orientation). The ECTB's profile does not show this balance, and can therefore be said not to have the capability to cope with change. The results of the profile are discussed in Chapter 4.

- Description: Rising global competition, the influence of advances in information technology and the re-engineering of business processes are some of the imperatives that force organisations to restructure their businesses. In South Africa, the situation is even more compelling, with the recent democratisation of the country that requires companies to implement certain restructuring programmes designed to empower previously disadvantaged individuals. Organisational restructuring is therefore inevitable for any organisation. These changes, however, do affect organisations and employees. Employees become insecure, confused about their jobs, and therefore less productive. To the extent that change can adversely affect both organisations and employees, it becomes critical that organisations should implement it carefully, if they are to survive. To achieve this, requires managers to fully understand drivers of change, the possible consequences of change on both organisation and employees, and to take appropriate actions. The main objective of this study was to identify possible approaches that organisations can pursue in implementing restructuring without adversely affecting the employees. The practical context chosen was an organisation that had recently implemented organisational restructuring. The research methodology for this study entailed the conducting of an intensive study of the relevant literature, to determine what the theory reveals in respect of restructuring strategies that can assist organisations in effectively implementing the restructuring process. Dissertations, theses, research reports and journals were consulted, in an attempt to formulate a theoretical basis for this study. The contemporary literature reveals that there are various strategies that organisations can employ to effectively restructure their organisations with minimal adverse influence on employees. The restructuring organisations should ensure that employees are genuinely involved in the process at the iv outset. The desired changes and the benefits thereof, should be clearly and consistently communicated to the employees at the beginning of the restructuring process. An empirical study was then conducted at the chosen organisation that had recently embarked on an organisational restructuring. The focal point of the empirical study was to determine how this organisation had implemented its restructuring process. The main purpose was to establish the impact that this restructuring had on the morale and motivation of the employees. The final step of this study included an assessment of the findings. This was done so that suitable conclusions could be drawn and appropriate recommendations made. The conclusions revolved around the effects of restructuring on the employees of this organisation. The focus of the recommendations was on what approaches the restructuring organisations should follow to successfully and effectively implement the restructuring process, without adversely affecting the employees.

- Description: Knowledge Management is associated with organisational initiatives in response to the demands of a knowledge-based economy in which the potential value of knowledge as a source for competitive advantage is recognised. However, the lack of a common understanding about knowledge itself, its characteristics and how it is constructed has led to diverse approaches about how to "manage" it. This study presents a critical overview of traditional and contemporary KM approaches. The main focus of this study was to discover and apply a suitable methodology for assessing an organisation's knowledge processing environment. This includes an analysis of the current practices and behaviours of people within the organisation relating to the creation of new knowledge and integrating such knowledge into day-to-day work. It also includes inferring from the above practices those policies and programmes that affect knowledge outcomes. This research makes extensive use of the Knowledge Life Cycle (KLC) framework and the Policy Synchronisation Method (PSM) developed by advocates of the New Knowledge Management movement. A case study approach was followed using a range of data collection methods, which included personal interviews, a social network survey and focus group discussions. The selected case is the small IT department at the East London campus of Rhodes University. Evidence from the case suggests that the knowledge processing environment within the IT department is unhealthy. The current knowledge processing practices and behaviours are undesirable and not geared towards the creation of new knowledge and the integration of such knowledge within the business processes of the IT department. There is little evidence of individual and organisational learning occurring and the problem solving process itself is severely hampered by dysfunctional knowledge practices. The study concludes that the above state of affairs is a reflection of the quality and appropriateness of policies and programmes in the extended organisation. Equally, the local definition of rules, procedures and the execution thereof at a business unit level is mostly lacking. The study illustrates that a systematic assessment of the knowledge processing environment provides the organisation with a sound baseline from where knowledge-based interventions can be launched.

- Description: The research problem of this study was to assess the extent to which the appraisal system for junior and middle level managers in the South African National Defence Force (SANDF) met the requirements and guidelines for performance appraisal as stipulated in the literature. To achieve this objective, the following procedure was followed: · A survey of existing literature, related to performance appraisal, was conducted. The literature study focused on the requirements for an effective performance appraisal system, appraisal methods and appraisal errors. Attention was also focused on who should take responsibility for performance appraisal and the importance of regularly evaluating the performance appraisal system to meet the demands of a changing environment. The second part of the literature study dealt with the guidelines for establishing an effective appraisal system as well as performance management processes and cycles that are critical for the effectiveness of an appraisal system. The theoretical study formed the basis for the development of a survey questionnaire to establish the extent to which junior and middle level managers in the SANDF agreed with the theoretical guidelines. The survey was administered to a randomly selected group of junior and middle level managers who were representative of the South African Army, Airforce and Medical Services. The empirical results indicated that there was concurrence with many of the guidelines in the literature, but that there were areas that could be improved. It became evident that many respondents felt that the current system was not entirely fair and was not adapted to meet the needs of the integrated SANDF. Specifically, results indicated that the system should be re-evaluated to eliminate bias and to enhance the development of clear standards, both on a quantitative and qualitative level. It became clear that training and communication were important to the successful development and utilisation of a performance appraisal system. An effective performance appraisal system that is integrated with the overall performance management system of an organisation will enhance productivity, satisfaction and the attainment of goals.

- Description: The research problem addressed in this study was to analyse and report on the potential use of Spoornet’s excess warehousing to support the Industrial Development Zones (IDZs) in the Eastern Cape. In order to achieve this objective, a literature study was undertaken to ascertain the world-class practices for warehousing. A study was conducted on Spoornet strategy in order to determine whether the company can apply its existing strategy for warehouse operations. The empirical results obtained, indicated that there would be a need for warehousing to support the IDZs in the Eastern Cape. There would be opportunities for storage of raw materials, distribution of parts for production, and finished goods to be delivered to consumers. Spoornet has gained ground on its competitor with respect to logistics and has progressed with its “Freight Logistics Solution” initiative. In conclusion it was recommended that Spoornet uses its existing strategy and convert their goods sheds into world-class warehousing. The warehouse space can be used as a trade-off to gain rail clients.

- Description: 1.1 MAIN PROBLEM A major concern in South African schools, especially in the disadvantaged areas, is the absence of effective leadership. Problems such as a lack of planning, an absence of vision, unfair resource allocation and feelings of uncertainty indicate a lack of meaningful leadership within the schools (Sterling and Davidoff, 2000:5). South Africa currently lacks a coherently explicit policy for the in-service training of school leaders. Until recently there has been no literature specifically addressing the problems school leaders face in black schools, no black professional organization for black school leaders, few opportunities for the discussion of ideas between departments, and few opportunities for training both before and after taking up a leadership position (Taylor and Tsukudu, 1995:111). The types of skills needed by School Management Teams(SMTs) for the effective management of schools depend on factors such as the needs of individual senior management members, the schools, the education system, the existing expertise of SMT members and their previous training. The purpose of skill development is to help develop and improve both the individual and the team performance of leaders responsible for managing schools in order to improve the functioning of schools(Mashinini and Smith,1995:133-135). In a growing number of developed and developing countries, a need for the more effective management of schools is becoming more important. Good management is regarded as essential if resources, both human and material, are to be used to maximum benefit so that schools make a valuable contribution to the economic and social well-being of societies (Taylor and Tsukulu, 1995:108). According to Sterling and Davidoff (2000:3), South African education is in a process of reconstruction and change. For those involved in education, the context feels unstable and at the point of delivery, the school, pressure is experienced. In addition to these problems, the socio-economic conditions result in many learners expecting not to be employed after completing their studies. This contributes to a feeling of despondence and demotivation amongst learners, which is often expressed in absenteeism, and a lack of commitment to their own education. Since 1996, reports by people in educational authority have confirmed a need for proper management training for managers in the South African educational system. In the past managers have been appointed to managerial positions such as head of department (HOD), deputy principal and principal without proper prior training. They have had to learn through trial and error and have made mistakes in the process. This situation is considered as neither inductive nor productive to a culture of teaching and learning (Deventer and Kruger, 2003:62). A study conducted by Steyn (1998:131-137) concluded that in the new South African dispensation, principals need to work closely with their first line managers in order to perform their 2 functions effectively. Steyn is of the opinion that a participative orientation in schools will be more effective than a centralized hierarchical orientation. The picture described above concerning the South African system and problems currently faced by teachers depicts a difficult environment which will not change overnight and one which requires effective intervention measures. This leads to the following problem, which will be addressed by this research. What management development skills do SMTs need to enhance their ability to manage schools effectively?.

The types of skills needed by School Management Teams(SMTs) for the effective management of schools depend on factors such as the needs of individual senior management members, the schools, the education system, the existing expertise of SMT members and their previous training. The purpose of skill development is to help develop and improve both the individual and the team performance of leaders responsible for managing schools in order to improve the functioning of schools(Mashinini and Smith,1995:133-135). In a growing number of developed and developing countries, a need for the more effective management of schools is becoming more important. Good management is regarded as essential if resources, both human and material, are to be used to maximum benefit so that schools make a valuable contribution to the economic and social well-being of societies (Taylor and Tsukulu, 1995:108). According to Sterling and Davidoff (2000:3), South African education is in a process of reconstruction and change. For those involved in education, the context feels unstable and at the point of delivery, the school, pressure is experienced. In addition to these problems, the socio-economic conditions result in many learners expecting not to be employed after completing their studies. This contributes to a feeling of despondence and demotivation amongst learners, which is often expressed in absenteeism, and a lack of commitment to their own education. Since 1996, reports by people in educational authority have confirmed a need for proper management training for managers in the South African educational system. In the past managers have been appointed to managerial positions such as head of department (HOD), deputy principal and principal without proper prior training. They have had to learn through trial and error and have made mistakes in the process. This situation is considered as neither inductive nor productive to a culture of teaching and learning (Deventer and Kruger, 2003:62). A study conducted by Steyn (1998:131-137) concluded that in the new South African dispensation, principals need to work closely with their first line managers in order to perform their 2 functions effectively. Steyn is of the opinion that a participative orientation in schools will be more effective than a centralized hierarchical orientation. The picture described above concerning the South African system and problems currently faced by teachers depicts a difficult environment which will not change overnight and one which requires effective intervention measures. This leads to the following problem, which will be addressed by this research. What management development skills do SMTs need to enhance their ability to manage schools effectively?.

- Description: There is a demand for improved communication and efficiency within the work place. As emails are generally used more than issue tracking systems, this paper will investigate a way of integrating the main fea-tures of email with those of an issue tracking system to ensure tasks are completed and if not information is provided to the relevant people at the relevant times. This will be done by creating an issue in an issue tracking system that is linkable to an email so as to track tasks that need to be done and follow the task through until completion.

- Description: This research explores the role, which the construct, service quality plays in an internal marketing setting. This is achieved by evaluating the perceptions and expectations of the production department with regards to the service quality provided by the maintenance department of a South African motor vehicle manufacturer. This was done using the INTSERVQUAL instrument, which was found to be a reliable instrument for measuring internal service quality within this context. A positivist approach has been adopted in conducting this research. There are two main hypotheses for this study: the first hypothesis is concerned with the relationship between the overall internal service quality and the five dimensions of service quality namely: tangibles, empathy, reliability, responsiveness and reliability. The second hypothesis focuses on the relationship between the front line staff segments of the production department and the five dimensions of internal service quality. The results of this research suggest that the perceptions and expectations of internal service customer segments plays a major role in achieving internal service quality. In addition, the importance of the INTSERVQUAL instrument in measuring internal service quality within the motor vehicle manufacturing environment is confirmed.

- Description: In many industries, service is the critical determinant of success or failure. Service failure is almost inevitable, and this has the potential for the organisation to lose its customer. However, if implemented successfully, Service Recovery can rectify the breakdown in service, and turn angry, frustrated customers into loyal ones. Service Recovery is vital for profitability, especially for companies operating in the services market, like First National Bank (FNB). Unfortunately, few service firms know how satisfied customers are with their Service Recovery efforts, and FNB is no exception. This study attempted to rectify the situation, to ensure that the bank does not fail its customers a second time. The major focus of the study is to assess client satisfaction with Service Recovery (SR) from FNB. By using the RECOVSAT instrument (developed by Boshoff in 1999), the study aims to establish how effective FNB was in terms of the six dimensions of SR, namely communication, empowerment, feedback, atonement, explanation, and tangibles. The relationship between each of the dimensions and customer satisfaction, as well as between customer satisfaction and loyalty, was measured, and a hypothesis for each relationship rejected or accepted. The empirical results show that, from 702 complainants, a RECOVSAT score of 68% was computed, which could be regarded as only satisfactory. The dimensions of communication, explanation, atonement, and empowerment, had the strongest positive correlation with customer satisfaction, while feedback and tangibles, although positively correlated, were not statistically significant, and thus not as important as the first four dimensions. FNB performed best on tangibles (81%), then communication (75%), explanation (70%), atonement (68%), empowerment (62%), and lastly feedback (51%). The study reinforced the view that customer satisfaction is positively related to loyalty. Other findings were that, administration and errors were the most frequent complaints, followed by pricing, fees, and interest, while time delays/waiting were the third most numerous. Over 54% of complainants had been with the bank for over 10 years, which could be a problem if the customers had left the bank, as the profitability of a customer generally increases with time. Age and gender did not appear to be factors that influenced behaviour of complainants. In terms of the managerial implications, it is recommended that FNB implement a Customer-Complaint-Handling (CCH) system that is both national and inter-group. The bank should also focus on empowering employees, improving communication skills, explaining to customers why the problem occurred, apologising, and offering some atonement. By adopting the recommendations, FNB should improve their service recovery, and as a consequence, their customer satisfaction and loyalty, and profitability should also increase.

The nature of business on the Internet in South Africa and the World is investigated. The extent of Internet banking in South Africa is ascertained and the expectations and perceived problems of online bankers are discussed. The importance of Human Computer Interface and Web Interface Design for successful business is promoted with a discussion of their guidelines and principles. Web Evaluation techniques and Tools are assessed and The "Gartner" Web evaluation tool is selected to evaluate the three bank Web sites. The results of the evaluation indicate that there are several generally well implemented design criteria used by all of the banks while some criteria are not implemented at all. Each bank is discussed individually to identify strong and weak features of their Web site design. Essential aspects of Web design have been proposed for inclusion during the design of "online" Banking Web sites.

An evaluation of paired comparison models

- Description: Introduction: A typical task in quantitative data analysis is to derive estimates of population parameters based on sample statistics. For manifest variables this is usually a straightforward process utilising suitable measurement instruments and standard statistics such the mean, median and standard deviation. Latent variables on the other hand are typically more elusive, making it difficult to obtain valid and reliable measurements. One of the most widely used methods of estimating the parameter value of a latent variable is to use a summated score derived from a set of individual scores for each of the various attributes of the latent variable. A serious limitation of this method and other similar methods is that the validity and reliability of measurements depend on whether the statements included in the questionnaire cover all characteristics of the variable being measured and also on respondents’ ability to correctly indicate their perceived assessment of the characteristics on the scale provided. Methods without this limitation and that are especially useful where a set of objects/entities must be ranked based on the parameter values of one or more latent variables, are methods of paired comparisons. Although the underlying assumptions and algorithms of these methods often differ dramatically, they all rely on data derived from a series of comparisons, each consisting of a pair of specimens selected from the set of objects/entities being investigated. Typical examples of the comparison process are: subjects (judges) who have to indicate for each pair of objects which of the two they prefer; sport teams that compete against each other in matches that involve two teams at a time. The resultant data of each comparison range from a simple dichotomy to indicate which of the two objects are preferred/better, to an interval or ratio scale score for e d Bradley-Terry models, and were based on statistical theory assuming that the variable(s) being measured is either normally (Thurstone-Mosteller) or exponentially (Bradley-Terry) distributed. For many years researchers had to rely on these PCM’s when analysing paired comparison data without any idea about the implications if the distribution of the data from which their sample were obtained differed from the assumed distribution for the applicable PCM being utilised. To address this problem, PCM’s were subsequently developed to cater for discrete variables and variables with distributions that are neither normal or exponential. A question that remained unanswered is how the performance, as measured by the accuracy of parameter estimates, of PCM's are affected if they are applied to data from a range of discrete and continuous distribution that violates the assumptions on which the applicable paired comparison algorithm is based. This study is an attempt to answer this question by applying the most popular PCM's to a range of randomly derived data sets that spans typical continuous and discrete data distributions. It is hoped that the results of this study will assist researchers when selecting the most appropriate PCM to obtain accurate estimates of the parameters of the variables in their data sets.
