Every product manager has their own voice, their own style. In the beginning, it’s all about gut instinct, intuition and understanding why humans do the things they do. From that point on, the paths digress. Some communicate as little as they need, some bring all stakeholders on the table with fullest transparency, some bring them on the table for the What and Why but not the How. Some play good cops and bad cops, some dispense information very sparingly, some play with the information they have to dispense.
Like Sardar Patel, and like Narendra Modi, every product manager has a voice, a method of rallying people, of building a narrative, and of finding what makes them tick. Just like every politician.
