Once you have mapped the stakeholder landscape, you can focus on identifying the executive stakeholders and sponsors for your project. These are the people who have the highest level of power, interest, influence, and involvement in your project. They are typically senior managers, directors, or executives who can authorize, approve, fund, or champion your project. You can use various sources of information to identify them, such as the project charter, the business case, the organizational chart, or the previous projects. You can also ask for referrals from your existing stakeholders or sponsors, or conduct interviews or surveys to validate your assumptions.
