Chris Halliwell, director and co-founder of the online Technology Marketing Center (TMC) at the California Institute of Technology's Industrial Relations Center, will interview Tauss about methods for discerning customer value for new technologies and the need to focus business team resources on the early, opinion-leading customer.
