IMVU is referred to as the first "Lean Startup", and was the proving ground for applying Build-Measure-Learn (the Scientific Method) to rapidly iterate and continuously improve its product development process, resulting in a valuable strategic advantage and highly productive, happy, and motivated teams.

This lecture focuses on IMVU's continuous improvement to product development process through experimentation. Success factors are reviewed, including a culture that values and supports experimentation and learning, Agile and XP engineering practices (which support iterative development), and strong product vision and user experience design. Recent product development process experiments will be shared.
