Abstract: Methods, systems and networks for assessment, development, and management of the selling intelligence and sales performance of individuals among a population of individuals competing in a field. The systems and networks support (i) 3D avatar-based virtual reality (VR) gaming environments supporting conservations and simulations that challenge and assess sales people and develop their sales skills, (ii) automated scoreboards showing the standing among assessed individuals competing on a team, within a company or industry, and (iii) automated coaching and performance feedback with dashboards and reporting tools to help sales managers/leaders develop the selling intelligence of sales representatives and increase their sales productivity.
