A stakeholder is anyone affected by what a business does, or who can affect it: owners, employees, customers, suppliers, lenders, the local community, government.
The useful part is not the list, it is the conflict. Stakeholders want different things and cannot all be satisfied at once.
Owners generally want profit and return. Employees want pay, security and conditions. Customers want quality and low prices. Suppliers want to be paid promptly and fairly. Lenders want the business to stay solvent. The community wants employment without noise, traffic or pollution.
Raising prices helps owners and hurts customers. Cutting wages helps owners and hurts employees. Paying suppliers faster helps suppliers and hurts cash flow. Opening on Sundays might please customers and displease staff and neighbours.
A decision is rarely 'good for stakeholders'. It is good for some and costly to others, and the skill is being able to say which and by how much.
Never write 'this affects all stakeholders'. Name two, say what each wants, and explain why the decision cannot satisfy both.
