Research shows that the most successful teams have the means in place to take action and they build effective relationships to motivate and sustain action. The systems approach behind the Team Diagnostic Assessment focuses on Positivity as a necessary condition for Productivity. The 80 items in the questionnaire measure seven Positivity strengths and seven Productivity strengths. The combined profile of these fourteen strengths, as seen by all members of the team, gives a picture of how the team is functioning. The Team Diagnostic graphic profiles provide a benchmark for on-going team development.
