Definition:
A stakeholder is any individual or group that affects an organisation or is affected by it. Stakeholders are often classified as internal (CEO, different level managers, employees and shareholders/owners) or external (customers, suppliers, unions, competitors, the government and society as a whole).
Governments regulate organisations in order to protect the public interest; governments also enforce laws and reprimand companies when necessary. In addition, governments, particularly local governments, are dependent upon companies to provide tax revenues and employment.
Suppliers are the individuals and businesses that sell goods and services to another organisation. They want to be paid fair and reasonable prices for these inputs.
