Prerna Kale is a product manager who advocates for innovation and an agile mindset. She believes agile and innovation go hand in hand by allowing teams to focus on crucial features that will create new, desirable products. Some ways she suggests teams innovate include using open spaces for brainstorming, setting OKRs to guide product development, conducting innovation games for product discovery and risk assessment, and facilitating innovative retrospectives like a futuristic hot air balloon theme. Her overall message is that teams should lead innovation rather than follow by continuously challenging assumptions and creating new solutions.
