The COMPOSITE team at the Institute of Work Psychology at the University of Sheffield (United Kingdom), Chrstine Turgoose, Kamal Birdi, Kerry Allen, Ian McDonald, and Julia Vössing, developed and designed within COMPOSITE's WP3 (which is dealing with knowledge sharing capabilites and best practices in police organisations) a Knowledge Sharing Diagnostic Instrument (EKSPO-DI manual and EKSPO-DI questionnaire) to provide police organisations with the opportunity to assess how effectively knowledge is being shared in a range of situations.
