Greg Dunning and Tony Salgado presented on shift left strategy, which aims to reduce support costs by pushing more issues to lower tiers like tier 1 support or self-service options. This can significantly reduce labor costs, freeing up time for higher priority work. Shift left strategies discussed included using chat as a first line of communication, intelligent routing of chats, integrating chat and ITSM systems, enabling collaboration on issues, centralized knowledge bases, and connecting chat to remote support when needed. The goal is to handle more issues at the lowest possible tiers through automation, self-service and empowering tier 1 agents.
