Once you know the roles, it's important to segment them based on their level of interest, influence, and authority. This will help you prioritize your product demo and focus on the most relevant features and benefits for each role. For example, you can divide the roles into four categories: decision-makers, influencers, users, and evaluators. Decision-makers are usually senior executives or managers who care about the strategic and financial impact of your product, so you should emphasize how your product aligns with their vision, goals, and budget. Influencers are usually experts or advisors who care about the technical and functional aspects of your product; therefore, it's important to demonstrate how your product solves their problems, meets their standards, and integrates with their systems. Users are usually employees or customers who care about the usability and convenience of your product; so you should show how your product makes their tasks easier, faster, and more enjoyable. Lastly, evaluators are usually analysts or consultants who care about the performance and quality of your product; thus, it's important to highlight how your product delivers superior results, features, and support.
