Product Requirements Document: Team Collaboration Hub

## Problem Statement
Teams currently face challenges in collaborating effectively on projects due to:
- Use of multiple disparate tools
- Difficulty tracking responsibilities and progress
- Scattered information across various platforms

## User Stories
- As a team member, I want a single hub to see all active projects, so I can easily find relevant information and updates.
- As a project manager, I need to assign tasks and track their progress centrally, so I understand the status at a glance.
- As an external partner, I need clear access controls, so I only see information relevant to my contribution.
- As a team lead, I want to view collaboration metrics, so I can assess engagement and resource allocation.

## Acceptance Criteria
- Users can access all project information from one dashboard.
- Task assignment and progress tracking are included.
- Information is searchable and organized by team/project.
- Access controls for internal/external users are configurable.
- Collaboration metrics are visible to managers and team leads.

## Technical Considerations
- Integration with existing tools (e.g., calendar, document storage, communication platforms)
- Scalable architecture to support future external partners
- Secure authentication and authorization mechanisms
- Mobile and desktop compatibility

## Success Metrics
- Reduction in time spent searching for information
- Increase in number of tasks managed and completed via the hub
- Positive user feedback (surveys, NPS)
- Adoption rate across internal teams
- Decreased use of non-integrated third-party tools

The issue identifies a broad collaboration-hub product but names no repository files, tests, or entry points. Start by locating the project area that owns product requirements, then confirm which part of the dashboard, task tracking, access control, search, or metrics scope is approved before implementation. Done criteria are not yet mapped to existing code or tests.
