<context>
The user needs to create a detailed project plan for an initiative with defined scope and timeline. This requires breaking down work into manageable components, allocating resources effectively, identifying risks, and establishing governance and communication structures.
</context>

<input_handling>
Required inputs:
- Project type and main objectives
- Timeline and completion deadline
- Team size and key resources available

Optional inputs (will use sensible defaults if not provided):
- Methodology preference (default: hybrid with milestone gates)
- Budget constraints (default: moderate, prioritize scope delivery)
- Stakeholder complexity (default: standard governance)
- External dependencies (default: minimal)
- Risk tolerance (default: balanced approach)
</input_handling>

<task>
Create a comprehensive project plan following these steps:

1. DEFINE PROJECT CHARTER
   - Establish objectives, scope, and success criteria
   - Identify key stakeholders and their interests
   - Document assumptions and constraints

2. BUILD WORK BREAKDOWN STRUCTURE
   - Decompose project into phases and work packages
   - Define deliverables for each phase
   - Establish dependencies between work packages

3. DEVELOP TIMELINE AND MILESTONES
   - Create schedule with critical path identification
   - Set milestone gates with go/no-go criteria
   - Build in appropriate contingency buffers

4. CREATE RESOURCE ALLOCATION PLAN
   - Assign team members to work packages
   - Identify skill requirements and gaps
   - Plan for resource constraints and availability

5. DESIGN RISK MANAGEMENT APPROACH
   - Identify key risks by category
   - Assess probability and impact
   - Develop mitigation strategies and contingencies

6. ESTABLISH GOVERNANCE AND COMMUNICATION
   - Define decision-making structure
   - Create communication plan for stakeholders
   - Set up reporting cadence and escalation paths

<output_specification>
Format: Phased project plan with WBS and timeline
Length: 1000-1500 words
Structure:
- Project charter summary
- Work breakdown structure with phases
- Timeline with milestones and critical path
- Resource allocation plan
- Risk register with mitigations
- Communication and governance plan
</output_specification>

<quality_criteria>
Excellent outputs will:
- Provide realistic time estimates based on stated resources
- Identify critical path and key dependencies clearly
- Include specific risk mitigations, not just risk lists
- Build in appropriate buffers (typically 15-20%)
- Assign clear ownership for all deliverables

Avoid:
- Over-optimistic timelines without contingency
- WBS without clear deliverables per phase
- Risk lists without actionable mitigation strategies
- Resource plans ignoring availability constraints
- Missing governance and escalation procedures
</quality_criteria>

<constraints>
- Stay within stated budget parameters
- Respect timeline requirements
- Account for team capacity realistically
- Include appropriate governance for project size
</constraints>
