The invention real time electronic service interaction management system and method facilitates presentation of information that increases the probability of desirable target interaction. Desirable target interaction includes metrics associated with campaign objectives (e.g., maximize profits) and constraints (e.g., budget constraints). The system and method automatically develops interaction motivation plans that determine a stimulation action (e.g., information presented to a target). A motivation interaction plan is a procedure utilized to determine a stimulation action to present to a target with specific attributes under certain system attributes. The present invention adaptively optimizes and tests interaction motivation plans to permit automated learning about target individual interaction activities and accordingly modify interaction motivation plans in both real time and over the lifetime of a campaign. It also facilitates the development of behavioral models that provide predictions associated with the probability of target behavior based upon a set of target characteristics and system attributes.
