A list of stakeholders in a project is a comprehensive inventory of all individuals, groups or organizations that have an interest in the success or failure of the project. It includes primary stakeholders, such as the project team, senior management and the customer, as well as secondary stakeholders, such as suppliers and contractors. By understanding the wants, needs, expectations and potential risks associated with each stakeholder, project managers can ensure successful outcomes for everyone involved. An effective list of stakeholders in a project encourages communication, collaboration and cooperation between all parties for maximum success.
