David Mainville, the CEO and co-founder of Navvia, discusses the need for a new model for sustainable IT service management. The current ITSM model is not delivering on its promises to improve service and reduce costs. Mainville argues for a human-centric model that focuses on winning hearts and minds through inspiration, collaboration, and accountability. Key aspects include building consensus through assessments, developing realistic plans, continuous communication, and governance to ensure the benefits of ITSM are sustained over time.
