# Solution preview chat

- Explain why we need the view
- Pros/cons
- Technical diagram for different stages
- In between stable states

- Phase 1 – Phase 2?
- Concerns about views
- Help understand the tradeoff
- esp around testing each phase

Audience:
- Sugendran
- Rob + other tech leads
- Doug
- Tim Riley
- Sushma

Outcome:
- Share our approach
- Understand the tradeoffs
- Success = Should be able to explain your solution afterwards

- Confidence we've kicked most of the tires
