The document provides an overview of the Team Health Check (THC), a questionnaire developed by Alyse Ashton and Richard Spence to assess team performance. The THC measures 8 critical areas of team effectiveness grouped into themes of direction, commitment to results, ownership, and conditions for success. It is designed to spark open conversations about a team's strengths and areas for improvement. Completing the questionnaire provides individual and consolidated team reports to facilitate action planning. Additional coaching and facilitation services are available to help teams address specific development goals.
