I took the course because I was working as a developer at an early startup and now I am doing PM work for the first time. It was good to learn what role a PM should play at each stage of product development and operation. Since I was preparing to launch a new product while working on my first PM job, I was able to apply the lecture content by following each chapter. The lecture was also very helpful when conducting user interviews and setting up a roadmap right after the launch. I reviewed the part about Product Discovery several times in particular. I was able to structure our goals by going through the process of planning product strategies and creating opportunity solution trees with the team. Among the concepts I learned in the lecture, there were many that I have not yet applied in practice, such as using indicators and data, so I plan to refer to the lecture regularly and learn while working as a PM. I took the course with gratitude to Minwoo because it relieved the frustration I had when I first prepared to be a PM. I would like to recommend it to PMs who are just starting out like me, and I think there is enough insight to learn even if you already have experience!
