In this report of a study using the Team Climate Inventory (TCI) tool, the researchers explain how the tool can be used in preparation for creating a practice development unit (PDU). The TCI provides a picture of the level and quality of teamwork in a unit using a series of Likert scales. The ward in this study was found to lack the necessary level of teamwork for successful PDU development and the researchers show how this information shaped trust plans. They recommend that units contemplating PDU accreditation should assess their level of teamwork prior to proceeding with bids.
