PDP was founded in 1978 with a single, simple principle: help organizations better understand their people. The core of PDP is the ProScan® Survey and resulting Comprehensive Report. In less than 10 minutes, individuals mark to what degree they believe 60 different descriptors match their characteristics and how they believe others perceive them. The data is then analyzed by PDP’s proprietary online application, generating complete, easily-interpreted reports for individuals and executives.
