The document discusses the importance of creating a service level agreement (SLA) between corporate real estate/facilities management departments and their customers to define expectations and measure satisfaction. It states that without an SLA to provide clear metrics, both sides lack an understanding of the other's needs and departments may be surprised by complaints about service quality. The document recommends including both quantitative and qualitative components in the SLA and measuring performance against the agreed upon standards to avoid misunderstandings and ensure satisfaction over time.
