Engaging stakeholders can significantly improve estimation accuracy, and here’s how High-Performance Project Management (HoPM) can help:

1. **Collaborative Workshops**: HoPM emphasizes the organization of workshops that bring all stakeholders together to discuss project requirements and expectations, ensuring that everyone has a shared understanding of the project scope.
2. **Stakeholder Involvement in Planning**: HoPM advocates for continuous stakeholder involvement throughout the planning process. Regular check-ins and feedback sessions can help refine estimates based on real-time insights.
3. **Stakeholder Analysis**: Using tools to identify and analyze stakeholder influence and interest can help project managers prioritize engagements and focus on those who can provide the most valuable input for accurate estimations.
