Best Practices for Enterprise Adoption

1. Start with high-impact use cases - Document drafting, email summarization, meeting recaps
2. Train users on effective prompting - Specific, contextual prompts yield better results
3. Establish governance policies - Define what content can be created/shared
4. Monitor usage and feedback - Track adoption and satisfaction metrics
5. Integrate with existing workflows - Copilot should enhance, not replace, processes

Copilot for Microsoft 365 represents a fundamental shift in how knowledge workers interact with productivity tools. The key is thoughtful adoption that maximizes value while maintaining appropriate governance.
