Team Diagnostic Survey


The Team Diagnostic Survey (TDS), based on the 6 Conditions framework, is a deeply researched and well-validated team effectiveness assessment. The TDS is a proprietary instrument developed by Harvard scholars and practitioners—Richard Hackman, Ruth Wageman and Erin Lehman. Their research identified 6 conditions that together predict up to 80% of a team’s effectiveness. This instrument and its underlying framework enables teams, team leaders and team facilitators to effectively design, launch and coach great teams.

Dr Angawi is an advanced practitioner in TDS. She administers the survey and debrief it for the leader and team over a two-day retreat.
