Stakeholder management involves identifying stakeholders, understanding their needs and interests, and building relationships to manage their impact and support. There are several models for classifying and prioritizing stakeholders. The salience model considers a stakeholder's power, legitimacy, and urgency to determine their importance. Stakeholders can be supportive, mixed blessing, nonsupportive, or marginal depending on their potential for threat or cooperation. Management strategies include involvement, collaboration, defense, and monitoring based on a stakeholder's assessment. The stakeholder typology model categorizes stakeholders as dormant, latent, demanding, dominant, dangerous, dependent, definitive or non-stakeholders based on their varying levels of power, legitimacy and urgency.
