This lecture was so informative that I regret only finishing it now. I felt the thrill of having the countless questions that arose while performing my first role as a PO finally organized. Of course, one cannot master everything about the PM/PO role through a single course, but I want to say that this lecture helped me at least establish the right direction and gain a clear perspective. Even after finishing the course, I continue to revisit and reflect on specific parts as needed. Thank you so much for creating such an essential and high-quality lecture.
