ServiceNow is enhancing its sales and customer success operations by developing an intelligent multi-agent system using LangChain's LangSmith and LangGraph tools, which address the challenges of agent orchestration and observability. This system orchestrates the entire customer journey, from lead identification to post-sales adoption and expansion, by coordinating complex workflows that were previously fragmented. ServiceNow's approach involves using a supervisor agent for orchestration and specialized subagents for specific tasks, activated by customer signals and lifecycle stages. LangGraph provides the necessary tools for sophisticated multi-agent coordination, enabling a modular and efficient development process, while LangSmith offers detailed tracing and evaluation capabilities to improve agent performance. The evaluation framework includes custom metrics tailored to each agent's tasks, leveraging LLM-as-a-judge evaluators and ensuring regression prevention. Currently in testing, ServiceNow plans to integrate real user data and utilize new multi-turn evaluation features for more comprehensive assessments of agent performance across the entire customer interaction.
