A project manager is leading a complex integration project with multiple external vendors, internal departments, and regulatory bodies. Each stakeholder group has different information needs, communication preferences, and decision-making timelines. Recent miscommunications have led to delays and rework. What should the project manager do FIRST?

Implement a centralized communication hub where all project information is stored and accessible

Develop a comprehensive stakeholder communication matrix that defines specific content, channels, frequency, and timing for each group

Establish regular all-stakeholder meetings to ensure everyone receives the same information simultaneously

Assign dedicated communication liaisons to each major stakeholder group
