This document discusses improving performance through collaboration between commissioners and providers. It argues that both sides must work together, as each has some responsibility, knowledge, and ability to solve problems, but no single group has all the answers. The old model of thinking performance is just one group's responsibility is outdated. The new model requires all groups to take responsibility and work together through open dialogue and data sharing to reduce referrals and wait times, as patients expect a collaborative approach. This partnership in Leicester led to meeting referral and cancer backlog targets through a focus on practical solutions over political issues and an atmosphere of support between partners.
