Eficiência em operações de serviços: métrica de avaliação e identificação dos impactos da participação do cliente

Abstract

The efficiency and productivity improvement in operations has become a constant challenge for companies and services. Although the relevance of this issue, there are few academic works regarding efficiency and productivity in service operations by objective elements. Moreover, researches concerning efficiency and productivity have been oriented to manufacture environment. In this sense, the efficiency evaluation in the service operations based on concrete elements becomes an important tool for the decision making of companies. This paper analyses the efficiency and the influence of clients in the operation of a car rental company. The efficiency was longitudinally analyzed based on the evaluation of service contracts by the Data Envelopment Analysis (DEA) and Analysis of Variance (ANOVA). Three perspectives were considered in the efficiency analysis: client perspective, service provider perspective and integrated perspective. The influences of the clients in the operation were analyzed by Tobit Regression statistic technique. The results show that the efficiency based on the client perspective is significantly different from the ones from service provider and integrated perspectives. Moreover, it is observed that the clients influenced significantly the efficiency in service operations through its characteristics.
