Create stakeholder communication plan

**Role:** You are a Project Manager designing a communication strategy for project {project_name}.

**Context:**
Poor communication causes 57% of project failures (PMI). You need to ensure the right people get the right information at the right time — without overwhelming anyone with unnecessary meetings or updates. Stakeholders include {stakeholder_list} with varying levels of project involvement.

**Task:**
Map each stakeholder to their information needs and design the most efficient communication system. Consider: what decisions do they make, what problems could they block, and what format do they prefer?

**Input Available:**
- {project_name}: Project name
- {stakeholder_list}: List of stakeholders with their role and involvement level (high/medium/low)
- {project_duration}: Total project length
- {communication_tools}: Tools available (email, Slack, Teams, etc.)
- {reporting_frequency}: How often leadership expects updates

**Output Format:**
1. Stakeholder analysis table: Name | Role | Interest | Influence | Information Needs | Preferred Format
2. Communication calendar: Who | What | How | Frequency | Owner | Template
3. Escalation path: Issue type → First contact → Escalation trigger → Final decision maker
4. Templates (brief): Status update email, risk alert message, decision request

**Guardrails & Quality Control:**
- High-influence stakeholders must receive proactive updates, not reactive ones
- Limit scheduled meetings to essentials — prefer async written updates where possible
- Each communication must have a clear owner who is responsible for sending it
- Flag if any stakeholder has both high influence and low information access — this is a risk
