A gestão de clientes é um processo que envolve a tomada de decisões estratégicas, que influenciam a composição do portfólio de clientes da companhia, e operacionais, que afetam o relacionamento dos clientes com a empresa no dia a dia. O framework sugerido nesta tese propicia a integração dessas duas perspectivas, permitindo aos gestores alocarem melhor os recursos de marketing, por possibilitarem (a) o incremento da eficiência da carteira de clientes, a partir da sua otimização, e (b) a identificação dos clientes mais propensos a gerarem lucros futuros, com base na modelagem de customer lifetime value (CLV) desenvolvida. A abordagem de otimização do portfólio de clientes foi elaborada para auxiliar os gestores a definirem os segmentos que devem ser alvo dos investimentos de marketing e tem como objetivo indicar a composição da carteira de clientes que proporcionará a rentabilidade, a diversificação do risco e a lucratividade desejadas pelos acionistas. A abordagem sugerida é uma adaptação para o marketing da teoria financeira do portfólio. Foram incluídas restrições específicas para a área de gestão de clientes que asseguram a exequibilidade dos portfólios recomendados, tanto em relação à necessidade de aquisição de clientes ou de redução da participação dos segmentos na carteira, quanto em relação à manutenção da lucratividade da empresa. Ademais, foram incorporadas opções de estimação do retorno, tais como a inclusão da tendência à série com base na modelagem SUR, além de serem avaliadas a utilização de duas proxies para o risco, a variância e o Conditional Value at Risk. De acordo com o framework de gestão de clientes proposto, a implementação das decisões estratégicas é viabilizada a partir da integração da análise dos resultados obtidos pela otimização com a avaliação proporcionada pelo modelo de CLV sugerido. Este, além de englobar a evolução do comportamento do cliente ao longo do relacionamento da empresa, considera o retorno e a matriz de probabilidade de troca de segmento de maneira individualizada. A heterogeneidade da matriz de Markov foi alcançada a partir da combinação convexa da matriz de transição geral com a matriz personalizada de cada cliente, possibilitando, assim, a priorização de clientes pertencentes a um mesmo segmento. O framework sugerido foi aplicado na base de clientes de uma grande empresa que atua nacionalmente na indústria de serviços financeiros. Após a constatação de que os segmentos podem gerar diferentes retornos e representar distintos níveis de risco para a companhia, foi feita a comparação dos resultados dos portfólios recomendados com o realizado. Os portfólios sugeridos desempenharam melhor de maneira consistente em termos de lucratividade e de eficiência, medida a partir do sharpe ratio. Em relação ao modelo de CLV, os resultados foram comparados com os obtidos a partir do modelo de Pfeifer & Carraway (2000), utilizado como ponto de partida para o seu desenvolvimento. As modificações incorporadas, além de possibilitarem a individualização por cliente, aumentaram a precisão da previsão dos valores individuais e a qualidade do ordenamento, mantendo a capacidade de avaliação do valor da base. Para resumir, foi proposto um framework de gestão de clientes que inclui a avaliação do risco, possibilitando aos gestores uma visão holística do negócio e particular de cada cliente. / Customer management is a process that involves strategic decision-making, which influence the composition of the customer portfolio, and operational decision making, which affect the relationship of each customer with the company. The proposed framework provides the integration of the strategic and operational perspectives, empowering managers to better allocate marketing resources as it enables (a) the increase of the efficiency of the customer portfolio, through its optimization, and (b) the identification of the customers that are more likely to bring profit in the future, through the customer lifetime value (CLV) model developed. The customer portfolio optimization method was built to help managers to define the customer segments that should be the target of their marketing investments. Its purpose is to indicate the customer portfolio composition that will provide the return, profitability and risk diversification desired by shareholders. The suggested approach is an adaptation to marketing of financial portfolio theory. In this way, customer management specific constrains were included to ensure the applicability of the recommended portfolios in terms of either the necessity of acquiring new customers or reducing the importance of a given segment in the portfolio as well as in terms of maintaining the company’s profitability. Furthermore, options of estimating return were incorporated such as the inclusion of the trend in the time series based SUR modeling as well as the optimizations were evaluated considering two proxies for risk, variance and Conditional Value at Risk. According to the proposed framework, the implementation of the strategic decisions concerning the changes needed in the customer portfolio become possible through the integration of the results of the optimization with the estimation of the value of each customer provided by the CLV model developed. In this model, besides accounting for the evolution of the customer behavior throughout the duration of his relationship with the company, we also consider, for each customer, his individual return and his individual transition matrix. The heterogeneity of the Markov matrix was reached with a convex combination of the general transition matrix and the personalized matrix of each customer. It, therefore, enables managers to priorize customers of the same segment. The suggested framework was applied to the customer database of a large national company from the financial services industry. Once evidenced that the customer segments can generate different returns and can have different levels of risk for the company, we compared the results of the recommended with the current. The portfolios suggested by the optimization performed consistently better in terms of profitability and efficiency, measured through sharpe ratio. Concerning the CLV model developed, we compared the results with Pfeifer & Carraway (2000) model, which was used as the start point for our model. The improvements implemented not only allowed the estimation of CLV at the individual level, but also increased the precision of the predictions for the customer lifetime values and for the customer ranking, maintaining the quality of the customer equity forecast. To sum up, our proposed framework which includes risk assessment enables marketing managers to have a holistic vision of their customer portfolio and to drilldown into a particular vision of each customer.

A questão da produtividade das atividades de marketing é um antigo debate da disciplina, porém ganhou destaque nos anos 1990 a partir de uma conjuntura que propiciou questionamentos sobre a eficácia e eficiência dos departamentos de marketing das empresas. Argumentou-se que o marketing deveria ir além das métricas tradicionais e explicitar as consequências de marketing para todos os stakeholders. Nesse sentido, os conceitos de customer equity e customer lifetime value têm se mostrado promissores em fazer a conexão marketing-finanças a partir de uma série de estudos iniciados nos anos 1990. Desde então foram elaboradas inúmeras modelagens a fim de mensurar a contribuição das ações de marketing empiricamente. De fato, evidências apontam para uma real contribuição de marketing dentro da empresa, seja pelo valor da marca, da clientela, da satisfação, lealdade entre outros. No entanto, a diversidade de modelos pode significar um entrave na padronização de cálculo e não existem pesquisas que estudem o impacto do modelo escolhido nos resultados da estimação nem sua implicação para tomada de decisão. A presente tese visou investigar até que ponto existe modelo dependência na estimação do customer equity e customer lifetime value, já que os resultados impactam diretamente na estratégia a ser utilizada pela gerência e, consequentemente, no desempenho da empresa A partir da classificação dos modelos foram comparados aqueles chamados de determinísticos, um grupo de modelos com características semelhantes e implementação simplificada. Os resultados indicam que, no caso da utilização do customer equity para avaliação financeira da empresa a estimação apresenta grande variabilidade, o que indica modelo dependência e a necessidade de aprofundamento metodológico, principalmente em negócios com alta heterogeneidade de margens e retenções. O ciclo de vida do cliente, por sua vez apresenta modelo dependência no que diz respeito a estratégia gerencial para maximizar o mesmo, sendo a seguinte: nos modelos de projeção infinita a retenção de clientes apresenta “prêmio” crescente no ciclo de vida esperado, enquanto que margens de contribuição tem peso maior em ambientes com retenção menor que 50% aproximadamente. Modelos com projeção finita, no entanto, não apresentam essa característica, sendo a retenção sempre a causar maior impacto marginal no valor do ciclo de vida esperado. Esses resultados fornecem evidências para concluirmos que existe modelo dependência na estimação de tais métricas. / The marketing productivity is an old debate in the field and has gained substantial attention since 1990’s as a product of a context that raised questions about the real contribution of marketing, its efficiency and efficacy. Managers argued that marketing should demonstrate its effects beyond traditional metrics and making them available to all business’ stakeholders. In this sense, customer equity and customer lifetime value has been used to make the connection between marketing and finance by 1990’s until now. In fact, research has shown that marketing contributes to firm value by elevating brand equity, customer loyalty and satisfaction, customer equity, among others. However, the large number of customer equity and customer lifetime models can be a difficulty on finding standard methodology, and there are no studies that compare model’s impact on results. This study aims to investigate the dependency of the models in estimating customer equity and customer lifetime value and its consequence on strategy adoption by managers. Starting from a classification proposal, a group of deterministic models were chosen to be compared. Results show that using customer equity for valuation purposes is model dependent, since models present great estimation variability, especially in a heterogeneous context. Customer lifetime value does produce divergent strategies and has model dependency as well: on models of infinite projection retention rates have increasing effect on expected customer lifetime values, but margins are preferred until a retention threshold of fifty percent. This does not occur within a model with finite projection, which retention rates has always more impact than margins. The sum of this results offer evidence that, indeed, model dependency on estimating customer equity and customer lifetime value exists.

M.B.A. / This study focuses on the impact of staff turnover on the level of service provided to customers. Understanding your customers' service requirements and .meeting or exceeding these needs and requirements and requests are key success areas for any business. There is, however, various factors that can have an impact on a business's understanding ofwhat the customer requires, and it is here that the customer relationship plays an important role. These relationships are built by people - staff. Staffturnover can be seen as the number ofstaff members that moved into, and out of, a position over a given time period, and can influence a business and customer relationships in different ways. A secondary study was embarked upon to determine what staff turnover and customer service entails. This focussed on defining the concepts, causes and possible effects thereof. A primary study was undertaken in the Bulk Cryogenic Gasses industry to determine if there is a link between the two variables. A questionnaire was sent out to various respondents to gather primary data to record customers perceptions of the impact regarding stafftumover on the level ofservice provided to them. Based on the responses received from the questionnaires, the majority ofcustomers were not impacted by staff turnover. The minority of customers who stated that they were impacted by stafftumover experienced a positive change. It is clear from this study that staff turnover does not impact negatively on the level of service provided to customers

M.B.A. / Building relationships with various groups of stakeholders is critical to an organisation’s success. One critical group of stakeholders are the organisation’s employees – the Internal Market. Internal Marketing is the key to superior service and the result is external marketing success. Internal Marketing can be defined as the promoting of the organisation and its product(s) or product line(s) to the organisation’s employees. Internal marketing as a term evolves from the notion that employees constitute an internal market within the organisation. This market needs to be informed, educated, trained, rewarded and motivated to meet external customers' needs and expectations. Understanding customer expectations is a prerequisite for delivering superior service. In order to achieve customer and organisation alignment, the organisations have to ensure that their internal processes, systems and employees are aligned to their common objectives of retaining customers and delivering superior service. Internal Marketing (IM) and Customer Service Centre (CSC) employees was chosen as the subject for this research to determine and establish the nature and perceptions of internal marketing in the service delivered by the Customer Service Centre employees from this specific Bank. IM has wide application in the service sector, but there is little empirical evidence that shows how Customer Service Centre employees perceive it. IM comprises of five components. Customer orientation and customer satisfaction involves leveraging customer relationships and their associated in-depth customer knowledge, which guides an organisation’s strategy towards meeting customer objectives. The implementation of specific corporate or functional strategies relates to the alignment, education and motivation of employees so that they can deliver on customer expectations, whilst meeting the organisation’s objectives. Employee motivation and employee satisfaction relates to attracting, developing, motivating and retaining qualified employees through job products that satisfy their needs. Inter-functional co-ordination and integration involves internal cross-functional relationships or co-operation to deliver effective service to the customers. The marketing-like approach refers to internal marketing-like activities that can influence employees to become customer-conscious and marketoriented. It is critical that employees within an organisation understand their impact and influence on other employees who are part of the complete value-chain that renders a service to the customer. This is important as employees within an organisation provide a service or support to other employees who deliver the end product or service to the customer. This study identified the employees’ perceptions of the internal marketing components within a Customer Service Centre of a leading Bank. The Customer Service Centre provides first level telephonic support to the Bank’s employees. This is a key function in order to ensure that all problems are resolved quickly so that the employees can deliver service to their customers. This research contains a background to the study, a literature review that was researched to clearly define and understand IM, it concepts, as well as related subjects to IM and call centre environments. A survey was then conducted with the CSC employees and the findings were then analysed and proposed recommendations were then concluded. The outcomes of the research identified that four of the five IM components are present in a CSC environment.

M.Comm. / The supposition was made that when customer service is not formally planned and managed, it could result in customer service, as a competitive strategy, not being optimally exploited due to it being done in an unco-ordinated, disorganised and ad hoc manner. The aim of this study is to set guidelines for customer service and management to ensure that customer service, is optimally exploited as a competitive strategy. This study commences with a theoretical framework followed by empirical research. During the theoretical study, customer service was defined and related theoretical aspects discussed. Emphasis was given to the conditions for applying customer service in the enterprise including the service quality model of Parasuraman, Zeithaml and Berry (1988). General management tasks were defined and the content of each task briefly discussed. Thereafter, the principles of these tasks were applied to customer service management. A customer service model was formulated, which integrated the theory of customer service and general management tasks. The model is based on the assumption that customer service management can be applied at executive, functional and operational level. A questionnaire was designed with the theoretical review as foundation. All facets of customer service management were analysed and questions were posed to determine the extent to which local banks comply with these management principles. The questionnaire was sent to the top ten Commercial banks in South Africa, selected according to the size of their total assets. The completed questionnaires were then analysed with the following results. The management tasks satisfactorily applied in customer service management are: planning, organising and leading. Management tasks that are not satisfactorily applied in customer service management as a result of all the gaps identified are: control, motivation, discipline, communication, delegating, decision making and the management of information. This indicated that customer service is not always managed on a formal and structured way because some of the management tasks are neglected. None of the general management tasks should be neglected as the omission of one of these tasks may lead to an ineffective management process. A customer service manager should thus continuously focus on each one of these management tasks to ensure that they are effectively carried out. If all the management tasks are performed out effectively, and are not neglected or ignored, the management process will be completed satisfactorily and improved results can be expected. The enterprise will therefore have a continuous competitive advantage over its rivals and the primary objectives of a enterprise, namely optimization of income, can thus be attained.
