An interpersonal development communications system and directory that determines a participant's motivators and values in view of a requester's motivators and values and automatically provides recommended guidance for the requester to manage and communicate effectively with participants who are subordinates, peers and superiors in an organization. A participant logs on to an Internet-based interpersonal development communications system server, or an intranet of his firm or company, and takes the Kinsel-Hartman Profile which includes four or five lists of 18 statements each. The participant ranks all 18 statements in each list, which in turn are used to create an individual profile report. This report presents the participant's blended scores of his thinking, combining his bias and capacities concerning each dimension of value. The interpersonal development communications application ranks those thinking orientations that serve as motivators into an ordered list that determines an interpersonal development profile summary describing how to deal with and manage another member of the organization. The requestor's profile results are compared with each member and integrated with the profile summary of each member to provide unique guidance on communicating with peers, subordinates and superiors in view of the requester's motivations and values.
