Developing effective subject matter experts (SMEs) takes more than a one-time training session—it requires ongoing evaluation, refinement, and support. But how do you know if your SME training program is actually working? In this session, two experienced SME trainers share lessons learned from several years of implementing and evolving an in-house SME development program. Attendees will learn which training strategies proved most effective, what challenges emerged after implementation, and how feedback, performance data, and coaching informed continuous improvement. The session will also discuss practical approaches for evaluating SME development efforts and offer recommendations for organizations with varying levels of resources. Whether you're building a new training program or looking to strengthen an existing one, you'll leave with practical ideas for creating a sustainable, effective approach to SME development.
