3. Verify critical functions
4. Address urgent issues

**See:** [Health checks](/learn/maintain/health-checks)

### Weekly (30-60 minutes)

1. **Run [Smart Analyst](/smart-analyst/introduction) deep sampling** to surface the week's trends and failure patterns across hundreds of conversations
2. Update Managed Topics content based on Smart Analyst insights
3. Sync Connected knowledge sources
4. Fix identified issues
5. Publish and promote changes

**See:** [Smart Analyst](/smart-analyst/introduction), [Managed Topics](/learn/maintain/knowledge-base), [Performance monitoring](/learn/maintain/performance-monitoring)

### Monthly (2-4 hours)

1. **Use [Smart Analyst](/smart-analyst/introduction) for a deep sampling review** – analyze containment blockers, handoff reasons, and sentiment trends across the full month
2. Optimize functions and performance
3. Update voice and audio settings
4. Address knowledge gaps identified by Smart Analyst
5. Test and validate improvements

**See:** [Smart Analyst](/smart-analyst/introduction), [Voice and audio](/learn/maintain/voice-audio-updates)

<Tip>
  When in doubt, use your [environments](/environments-and-versions/introduction) carefully. Make any changes in the **Sandbox**, test thoroughly, and only then promote up to **Live**.
