Data was collected from the company contracted to distribute the products in the state of Cear?. Analyses of thirteen sales coverage areas were performed considering first the output-oriented constant return to scale method (CCR-O), then this method with assurance region (AR-O-C) and finally the method of variable returns to scale with assurance region (AR-O-V). The method used in the first approach is shown to be inappropriate for this study, since it inconveniently generates zero-valued weights, allowing that an area under evaluation obtain the maximal score by not producing. Using weight restrictions, through the assurance region methods AR-O-C and AR-O-V, decreasing returns to scale are identified, meaning that the improvement in performance is not proportional to the size of the areas being analyzed. Observing data generated by the analysis, a study is carried out, aiming to design improvement goals for the inefficient areas. Complementing this study, GDP data for each area was compared with scores obtained using AR-O-V analysis. The results presented in this work show that DEA is a useful methodology for assessing sales team performance and that it may contribute to improvements on the quality of the management process. / Esta tese de mestrado prop?e utilizar a An?lise de Envolt?ria de Dados - DEA (Data Envelopment Analysis) na avalia??o de desempenho das equipes de vendas a partir de um estudo de suas ?reas de atua??o. S?o utilizados dados obtidos junto ? empresa contratada para distribui??o dos produtos no estado do Cear?. As an?lises das treze ?reas de vendas foram realizadas considerando o m?todo de retorno constante de escala orientado a produto (CCR-O), em seguida, esse m?todo com utiliza??o de regi?o de garantia (AR-O-C) e por ?ltimo o m?todo de retorno vari?vel de escala com utiliza??o de regi?o de garantia (AR-O-V). O m?todo utilizado na primeira abordagem mostra-se inapropriado para este estudo pois apresenta o inconveniente de gerar pesos com valor igual a zero, permitindo que uma ?rea avaliada obtenha escore m?ximo n?o produzindo. Utilizando-se restri??es de pesos, atrav?s dos m?todos da Regi?o de Garantia AR-O-C e AR-O-V, identificam-se a exist?ncia de retornos decrescentes de escala significando que a melhoria de desempenho n?o ? proporcional ao tamanho das ?reas analisadas. Atrav?s do m?todo AR-O-V foram encontradas nove ?reas eficientes. Observando os dados gerados pelas an?lises faz -se um estudo para projetar metas de melhoria para as ?reas ineficientes. Complementando o estudo, comparam-se os dados do PIB de cada ?rea com os escores obtidos na an?lise A R-O-V. Os resultados apresentados nesse trabalho garantem a utilidade da DEA como metodologia para a avalia??o de desempenho das equipes de vendas podendo contribuir para a melhoria da qualidade do seu processo de gest?o.
