Call Center Key Performance Indicators and Customer Satisfaction

This article purports to investigate the relationship - in an empirical way - between the various key performance indicators currently used for the management of call centers in Brazil and customer satisfaction. In this context, a set of call centers rendering services to a telecommunications company will be analyzed in order to verify which of their indicators are positively associated with customer satisfaction. A methodological approach based on surveys as well as stepwise multiple linear regressions is developed and applied in order to achieve the objective of this paper. It is seen that just the "FirstContact Resolution Rate" and the "Average Handle Time After the Call" indicators present a statistically significant relationship with customer satisfaction. Lastly, some alternative call center key performance indicators are proposed, in an exploratory way, so as to convey to an enhanced relationship between call center performance and customer satisfaction.
