Product management entails strategic oversight of the product and engineering team's roadmap. Instead of random features or mimicking competitors, a successful PM's product ideas should form a coherent strategy based on the product vision. Sourcing ideas can include user interviews, brainstorming, analyzing user behaviour, and examining solutions in similar industries. Prioritizing these ideas involves design, research, and data analysis. Despite potential challenges, the ultimate goal is to align the roadmap with the product strategy.
