A project manager is leading a complex system integration involving multiple vendors, internal departments, and regulatory agencies. Each stakeholder group has different information requirements, communication preferences, decision-making timelines, and reporting needs. Recent communication breakdowns have led to misaligned expectations and project delays. What should the project manager do FIRST?

Implement a centralized project communication portal where all stakeholders can access comprehensive project information

Develop a detailed stakeholder communication matrix that specifies content, channels, frequency, timing, and feedback mechanisms for each group

Establish regular multi-stakeholder meetings to ensure all groups receive the same information simultaneously

Assign dedicated communication coordinators to each major stakeholder group to manage their specific needs
