Explain What Stakeholder Management Actually Means in Practice

You've been told to manage your stakeholders and nobody explained what that means. This breaks it down practically: how to identify them, sort them by influence and interest, and keep the right ones engaged through a steady communication rhythm. Aimed at new project managers who want concrete habits rather than a vague instruction.
