In order to understand the project environment, stakeholder analysis is important. It helps the team to identify who the stakeholders are and what their needs are. It also helps them understand how they can influence these needs and make sure that they are met. The stakeholders of a project may include the client, key stakeholders, suppliers, internal stakeholders and external stakeholders. The key stakeholder is the person who has a major role in deciding what happens in a project. The internal stakeholders are people who work on the project or have an impact on it. The external stakeholders are people outside of the company who have an impact on it as well.
