O impacto da terceirização do call center em empresas de energia elétrica no Brasil

This dissertation seeks to recognize the impacts that outsourcing of the call center brings to firms of electrical energy in Brazil. For this research, two existing cases in the brazilian sector electric: i) case of Cemig, firm mineira of electrical energy; ii) case Light, firm carioca of electrical energy. The framework of this dissertation is based of the methodology of multiple study cases described by Robert Yin (2003). This work analyzed separately each of the cases and compared the results obtained in each analysis. In this way, this research aimed at analyzing the impacts that firms sufering in outsource the call center, despite the citys are diferents, like the factors of the environment. The obtained results suggest that the firms adopt the mixed call center, with the greatest part of outsources employees and with less proper. The importants impacts seeks in this research are the lost of the image, quality and the control of the process of answering. The aim impacts of a outsourcing the call center find in this research are the lost of the image of the firm and the reduction of the control of the process of customer service, impacting directly on the quality of the customer service.

A relação da motivação para o trabalho com as metas do trabalhador: um estudo de caso em uma operadora de call center

Having as basic purpose, that the work motivational strategies are more efficient when elaborated directly from the worker¿s personal goals and values, the study line of this dissertation searched to identify the worker¿s motivational employee¿s profile from call center industry. The knowledge of this motivational profile makes possible the development of differentiated programs of motivation inside the organization, aiming to attend goals of diverse groups of workers. In order to achieve the considered objective, the present dissertation analyzed one of the biggest companies in call center¿s inside Brazilian market, the BrasilCenter Communications Ltda. In such a way, in the first stage of the study, a bibliographical research was carried out, with the objective to collect contributions from diverse authors on the motivation subject, and also a modern theory of values was presented, verified empirically in more than 60 countries, which identifies the people¿s motivational structure. Having as base the results of these studies, the worker¿s concept profile motivational and argued its way of evaluation in the organizations it was boarded. In the second stage, a field research was carried out, with the application of the Inventory of Values of Schwartz theory (IVS), in order to identify the employee¿s motivational profile crowded in the Center of Attendance and Services (call center) company, located in Juiz de Fora city. The analysis of the results from the field research, based on the bibliographical data, identified that the values prioritized for the call center¿s employees are the ones that serves the collective and mixing goals. This motivational profile offers some perspectives of employee¿s valuation that correspond to their goals and interests. The displayed results point respect to the centrality of the types of values benevolence, conformity, security and universalism among the participants in the sample. As the accented was more among the employees it was the search of collective results it, is concluded that the more appropriate valuation strategies are those related to the tolerance for the ideas and opinion of the others, to harmonic a organizational enviroment, the concern with the quality of life at work and the social aspects of the work.

Uma investigação empírico-exploratória acerca da causalidade dos indicadores operacionais de call center com a satisfação dos clientes

Year after year the call center industry comes presenting high growth, either in Brazil or the world, using increasing contingent of people and receiving large amount of financial resources. Supporting all this industry, exists a theoretical reference that privileges the search of the improvement of diverse operational performance indicators. This study, empirically examines the relationship between caller satisfaction and diverse operational performance indicators currently used for call center management in Brazil. For in such a way, a group of telecommunications segment call centers will be used searching to determine which indicators are really more significantly correlated with the customer satisfaction. Of this form, it is aimed at to add new evidences and explanations to existing literature, in way that companies of call center industry can give a more adequate service to their customer, opposite to solely focus its efforts in the improvement of a great set of performance pointers that, effectively, can not become related with the customer satisfaction.

Linha ocupada, cliente livre!: um estudo sobre contact centers e fidelidade dos clientes de operadoras de telefonia celular

O presente estudo trata da influência do Contact Center na interação de clientes e empresas de telefonia celular e a resultante fidelização desses clientes. A interação entre os clientes e as empresas, quando bem gerenciada, pode ser um diferencial competitivo relevante, num mundo em que as inovações e sua disseminação ocorrem muito rapidamente. Ao contrário, um relacionamento mal gerenciado pode levar à infidelidade dos clientes e à conseqüente troca de fornecedor. Para avaliar a satisfação dos clientes sobre a sua interação com as empresas foi realizado um survey, enviando-se e-mails para usuários residentes no Estado de São Paulo e recebendo-se suas respostas por meio de um endereço na Web. Para a análise do tema, foram utilizadas as teorias de Marketing de Serviços, Marketing de Relacionamento e de Orientação ao Mercado, bem como estudos relacionados aos Contact Centers (ou call centers) e fidelidade. Esta pesquisa contempla três áreas principais: Orientação ao Mercado da empresa; qualidade dos serviços do Contact Center; e fidelidade do cliente. Para a análise dos dados que compõem o escopo desta pesquisa, foram aplicadas técnicas estatísticas de Análise Fatorial e de Análise de Conglomerados (ou Clusters). Além disso, foi realizada uma análise comparativa de fidelidade às principais operadoras e uma simulação para se estimarem as potenciais perdas de clientes. Os resultados apontam para uma grande insatisfação dos clientes com empresas de telefonia celular e com o atendimento em aspectos que lhe são mais urgentes, como o atendimento às suas necessidades e a eficiência do Contact Center. E também assinalam uma forte tendência à infidelidade. Com a vinda da portabilidade do número do celular a partir de 2009, que permite que o usuário mantenha seu número mesmo trocando de operadora, o risco é ainda maior. Neste caso, os resultados mostram que 64% dos clientes declaram sua infidelidade à operadora atual. A relevância deste estudo para as organizações é que o mesmo apresenta uma perspectiva sobre o Contact Center, como ponto de relacionamento e incremento da satisfação do cliente, bem como de um diferencial competitivo que, aparentemente, vem sendo pouco prestigiado pelos profissionais de marketing.

Os impactos da reestruturação organizacional de uma empresa multinacional de alta tecnologia na área de treinamento e desenvolvimento de call center:aplicação da teoria das configurações de Mintzberg

Neste estudo realizamos uma pesquisa no setor de serviços de uma empresa multinacional de alta tecnologia, na qual ocorreram mudanças organizacionais envolvendo a área de treinamento e desenvolvimento, que atendia vários clientes de call centers, com sua equipe deixando de se reportar à Gerência Operacional local e passando a se reportar à área de Treinamento & Desenvolvimento Global. O objetivo foi contribuir para o papel do desenho organizacional da área de treinamento neste setor. O estudo teve como embasamento a Teoria das Cinco Configurações, de Henry Mintzberg, e as questões respondidas foram: que reestruturação a empresa estudada está implementando, de acordo com a teoria de Mintzberg, e quais são os impactos desta reestruturação para o departamento estudado, na visão dos entrevistados? O método utilizado foi o de estudo de caso e a nossa pesquisa foi realizada na organização desta área no Brasil, na qual coletamos dados através de fontes primárias, e empregamos observação direta e pesquisa de campo com entrevistas semiestruturadas com funcionários e clientes da área. Demostramos que a organização de treinamento estava se estruturando como uma Adhocracia Operacional e que a mudança foi positiva na visão tanto dos funcionários da área, quanto de seus clientes. Para avaliarmos o comportamento dos indivíduos do grupo, criamos duas tipologias a partir da categorização dos dados coletados. Concluímos que as pessoas do grupo tinham ação estratégica e foco em seu desenvolvimento profissional, o que é coerente com a estrutura Adhocrática de Mintzberg. As características de uma Adhocracia se mostraram positivas para uma área de treinamento de call center que atende a múltiplos clientes, conduzindo a equipe a ter foco mais estratégico, aumentando a autonomia e o engajamento, elevando o conhecimento, melhorando a comunicação, trazendo processos flexíveis e, como consequência, um resultado positivo para as operações atendidas.

Comparison between two caller groups of a medical call centre in Switzerland

OBJECTIVES: The incidence distribution of triage advice in the medical call centre Medi24 and the pattern of service utilisation were analysed with respect to two groups of callers with different insurance schemes. Individuals having contracted insurance of the Medi24 model could use the telephone consultation service of the medical call centre Medi24 (mainly part of the mandatory basic health insurance) voluntarily and free of charge whereas individuals holding an insurance policy of the Telmed model (special contract within the mandatory basic health insurance with a premium discount ranging from 8% to 12%) were obliged to have a telephone consultation before arranging an appointment with a medical doctor. METHODS: A cross-sectional study was carried out in the medical call centre Medi24 based on all triage datasets of the Medi24 and Telmed groups collected during the one year period from July 1st 2005 to June 30th 2006. The distribution of the six different urgency levels within the two groups and their respective pattern of service utilisation was determined. In a multivariable logistic regression model the Odds Ratio for every enquiry originating from the Telmed group versus those originating from the Medi24 group was calculated. RESULTS: During a one-year period 48 388 triage requests reached the medical call centre Medi24, 56% derived from the Telmed group and 44% from the Medi24 group. Within the Medi24 group more than 25% of the individuals received self-care advice, within the Telmed group, on the other hand, only about 18% received such advice. In contrast, 27% of the Telmed triage requests but only 18% of the Medi24 triage requests resulted in the advice to make a routine appointment with a medical doctor. The probability that an individual of the Telmed group obtained the advice to go to the accident and emergency department was lower than for an individual of the Medi24 group (OR 0.77, 95% CI 0.60-0.99). Likewise, the probability of self-care advice was decreased in regard to the Medi24 group (OR 0.80, 95% CI 0.75-0.85). However, regarding the advice to make a routine appointment with a medical doctor, the Telmed group was represented more frequently than the Medi24 group (OR 1.36, 95% CI 1.28-1.44). CONCLUSION: In respect of the triage advice, the Telmed group differed significantly from the Medi24 group within all urgency levels. The differences between the two groups in respect of the advice given were still less pronounced than expected against the background of their different contract conditions and the disparate temporal pattern of utilisation. We interprete this finding with the fact that appraising the urgency of health problems appropriately seems to be very difficult for the majority of people seeking advice.

Impact of cognitive load and frustration on drivers’ speech [Abstract]

Secondary tasks such as cell phone calls or interaction with automated speech dialog systems (SDSs) increase the driver’s cognitive load as well as the probability of driving errors. This study analyzes speech production variations due to cognitive load and emotional state of drivers in real driving conditions. Speech samples were acquired from 24 female and 17 male subjects (approximately 8.5 h of data) while talking to a co-driver and communicating with two automated call centers, with emotional states (neutral, negative) and the number of necessary SDS query repetitions also labeled. A consistent shift in a number of speech production parameters (pitch, first format center frequency, spectral center of gravity, spectral energy spread, and duration of voiced segments) was observed when comparing SDS interaction against co-driver interaction; further increases were observed when considering negative emotion segments and the number of requested SDS query repetitions. A mel frequency cepstral coefficient based Gaussian mixture classifier trained on 10 male and 10 female sessions provided 91% accuracy in the open test set task of distinguishing co-driver interactions from SDS interactions, suggesting—together with the acoustic analysis—that it is possible to monitor the level of driver distraction directly from their speech.

Automatic spoken language identification utilizing acoustic and phonetic speech information

Automatic spoken Language Identi¯cation (LID) is the process of identifying the language spoken within an utterance. The challenge that this task presents is that no prior information is available indicating the content of the utterance or the identity of the speaker. The trend of globalization and the pervasive popularity of the Internet will amplify the need for the capabilities spoken language identi¯ca- tion systems provide. A prominent application arises in call centers dealing with speakers speaking di®erent languages. Another important application is to index or search huge speech data archives and corpora that contain multiple languages. The aim of this research is to develop techniques targeted at producing a fast and more accurate automatic spoken LID system compared to the previous National Institute of Standards and Technology (NIST) Language Recognition Evaluation. Acoustic and phonetic speech information are targeted as the most suitable fea- tures for representing the characteristics of a language. To model the acoustic speech features a Gaussian Mixture Model based approach is employed. Pho- netic speech information is extracted using existing speech recognition technol- ogy. Various techniques to improve LID accuracy are also studied. One approach examined is the employment of Vocal Tract Length Normalization to reduce the speech variation caused by di®erent speakers. A linear data fusion technique is adopted to combine the various aspects of information extracted from speech. As a result of this research, a LID system was implemented and presented for evaluation in the 2003 Language Recognition Evaluation conducted by the NIST.

A survey on six sigma implementation in Singapore service industries

The concept of Six Sigma was initiated in the 1980s by Motorola. Since then it has been implemented in several manufacturing and service organizations. In case of services, health care and finance were major beneficiaries till now. The application of Six Sigma is gradually picking up in other services like; call centers, utilities and public services. This paper provides empirical evidence on Six Sigma implementation in service industries in Singapore. By using a sample size of 50 service organizations (10 responses are from organizations which have implemented Six Sigma), the paper helps in understanding the status of Six Sigma in service organizations in Singapore. The findings confirm the inclusion of critical success factors, critical to quality characteristics, tools and key performance indicators as observed from the literature. The revelation of “not relevant” as a reason for not implementing Six Sigma shows the need for understanding specific requirements of service organizations before its application.

Vehicle Routing Problem with Load Compatibility Constraints

The major contribution of this paper is to introduce load compatibility constraints in the mathematical model for the capacitated vehicle routing problem with pickup and deliveries. The employee transportation problem in the Indian call centers and transportation of hazardous materials provided the motivation for this variation. In this paper we develop a integer programming model for the vehicle routing problem with load compatibility constraints. Specifically two types of load compatability constraints are introduced, namely mutual exclusion and conditional exclusion. The model is demonstrated with an application from the employee transportation problem in the Indian call centers.

Aplicación de la Programación lineal a la asignación de personal en un centro de llamadas

[ES] La necesidad de gestionar y repartir eficazmente los recursos escasos entre las diferentes operaciones de las empresas, hacen que éstas recurran a aplicar técnicas de la Investigación de Operaciones. Éste es el caso de los centros de llamadas, un sector emergente y dinámico que se encuentra en constante desarrollo. En este sector, la administración del trabajo requiere de técnicas predictivas para determinar el número de trabajadores adecuado y así evitar en la medida de lo posible tanto el exceso como la escasez del mismo. Este trabajo se centrará en el estudio del centro de llamadas de emergencias 112 de Andalucía. Partiendo de los datos estadísticos del número medio de llamadas que se realiza en cada franja horaria, facilitados por la Junta de esta Comunidad Autónoma, formularemos y modelizaremos el problema aplicando la Programación Lineal. Posteriormente, lo resolveremos con dos programas de software, con la finalidad de obtener una distribución óptima de agentes que minimice el coste salarial, ya que supone un 65% del gasto de explotación total. Finalmente, mediante la teoría de colas, observaremos los tiempos de espera en cola y calcularemos el número objetivo de agentes que permita no sólo minimizar el coste salarial sino mejorar la calidad de servicio teniendo unos tiempos de espera razonables.

Une analyse en milieu de travail : Étude de cas d'une firme de sondage

[français] L’objectif de cette recherche est d’analyser l’organisation interne d’une firme de sondage sous l’angle des sphères du milieu de travail telles qu’identifiées par Bélanger, Giles et Murray (2004), soient : la gestion de la production, l’organisation du travail et la relation à l’emploi. Plus spécifiquement, nous chercherons à savoir comment se comporte la firme enquêtée face à la gestion de la flexibilité organisationnelle et quel est l’impact de celle-ci sur les trois sphères du travail. L’analyse utilise la méthodologie de l’étude de cas et fait appel à divers types de matériaux : des observations ponctuelles, des entrevues informelles et les bases de données administratives ainsi que les rapports d’évaluation des entrevues téléphoniques effectuées par les intervieweurs. De même, l’analyse des résultats utilise à la fois des méthodes plus classiques telles que les corrélations ainsi que des représentations graphiques et des analyses qualitatives. L’analyse permet de repérer une logique de fonctionnement à l’œuvre dans les différentes sphères de l’emploi : l’importante standardisation des processus de travail (dans le champ de la gestion de la production), la réduction des marges de manœuvre (dans le champ de l’organisation du travail) et la non reconnaissance de l’expertise des intervieweurs (dans le champ de la relation à l’emploi). Les contradictions repérées dans l’analyse, entre les sphères de l’emploi et les objectifs de flexibilité, montrent que les structures mises en place bloquent, dans une certaine mesure, la capacité d’initiative et d’adaptation que la flexibilité exige. La recherche a montré que ce qu’on demande aux intervieweurs est à la fois le reflet des exigences de la flexibilité, tel que constaté dans ce mémoire, mais aussi, des exigences sociales face à la méthodologie de sondage. Tout porte à déduire que celles-ci peuvent engendrer un plafonnement de la performance des employés. Mots-clés : centres d’appels, intervieweurs, firmes de sondage, flexibilité organisationnelle, gestion de la production, organisation du travail, relation à l’emploi, travail émotionnel.
