Stakeholders are all individuals or groups who influence your product or are influenced by it. This goes far beyond just the paying customer or your boss: also consider employees who need to work with the product (e.g., support, sales, financial administration), external partners, end-users, and even regulatory bodies. A clear understanding of your stakeholder landscape is crucial to know whose interests you need to consider in decisions.
It's useful to group everyone so you know who you can approach directly and who is indirectly involved.
It's not just the final decision-maker who matters: also people who will work with the solution later (support department, compliance or IT management). Or end-users who are not the buyer (e.g., teachers and students for an educational app, while management signs the contract). If you overlook these groups, obstacles or resistance may arise later.
If you only discover after launch that the support department has no idea how to support new features, you'll get complaints, slow responses, and unhappy customers.
