# Team Notification System PRD

## Background
Team members miss important updates because messages are scattered across Slack, email, and project management tools.

## Goal
Build a unified notification center that aggregates messages from multiple sources and delivers them based on urgency and user preferences.

## Core Requirements
1. **Aggregation**: Pull notifications from Slack, GitHub, and Jira
2. **Priority**: Auto-classify notifications as urgent/normal/low based on content and sender
3. **Delivery**: Push to mobile app, browser extension, or daily digest email
4. **Preferences**: Users can set quiet hours, mute specific channels, configure per-source rules

## Target Users
- Engineering teams (10-50 people)
- Using at least 3 collaboration tools

## Success Metrics
- 80% of users check notifications daily within first month
- Average response time to urgent notifications < 5 minutes
- 50% reduction in "I didn't see that message" incidents

## Timeline
- MVP: 6 weeks
- V1 with all integrations: 12 weeks

## Open Questions
- Should we support custom webhook sources?
- How to handle notification deduplication across platforms?
- Mobile app vs PWA for push notifications?
