The TDS is an instrument that assesses the standing of work teams on the conditions discussed in this chapter. A typical classroom project is to ask students to use the instrument as part of an analysis of the strengths and vulnerabilities of some team whose members are interested in learning about and improving their team.

The TDS is taken online and a graphical assessment report is also provided online. For a detailed description of the instrument and its psychometric properties, see Wageman, Hackman, and Lehman ( 2005 ). The TDS is freely available for educational, research, and government use; consulting and commercial users are asked to pay a fee to support programming and user services. The instrument can be accessed at: https://research.wjh.harvard.edu/TDS (educational, research, and government) or at: http://www.team - diagnostics. com (consulting and commercial).
