Sonia Mayer discusses overcoming organizational resistance to implementing a subscription strategy. Some key challenges included transitioning from a transactional model with over 1,200 unique products priced in multiple currencies to a subscription model with standardized packages. Lessons learned included starting with a single target market, engaging cross-functional teams, analyzing data to test pricing models, reviewing all business processes, and determining how to integrate new and old reporting systems during the transition. The presentation provides advice on taking a gradual "crawl-walk-run" approach to change and using customer data to continually refine the subscription strategy.
