Mariana shares insights on how product leaders can thrive in uncertain environments. Drawing from examples like Netflix's pivot to streaming and Zoom's pandemic success, she emphasizes that uncertainty is the norm rather than the exception. The presentation covers five key strategies: staying humble and knowing what you don't know, embracing uncertainty as a driver of innovation, testing theories with data, staying true to company DNA and values, and keeping customer needs as your compass. She advocates for scenario planning with realistic, optimistic, and defensive scenarios, and stresses the importance of building agile muscles during stable times to prepare for uncertainty.
