According to the PMBOK Guide, 7th edition, one of the principles of project management is to collaborate with stakeholders. This means that the project manager should identify, analyze, and engage the project stakeholders throughout the project life cycle, especially in an agile project where the stakeholder involvement and feedback are essential for delivering value. A stakeholder analysis is a tool that helps the project manager to understand the different perspectives, interests, needs, expectations, and influence of the stakeholders, and to plan the appropriate strategies to communicate and collaborate with them. By performing a stakeholder analysis, the project manager can handle the different stakeholders in a matrix organization more effectively, and avoid potential conflicts, misunderstandings, or misalignment of goals.
