Architecture overview
High-level diagram + description: which systems are involved, how they connect, what changes.
Data models
New tables / fields / relationships. Migration considerations. Indexes worth flagging.
API contracts
Endpoints, request / response shapes, error cases, authentication.
Failure modes
What can go wrong, how the system degrades, what gets retried vs surfaced.
Migration plan
If existing data needs to move or transform, the steps + rollback plan.
Open technical questions
What needs an engineer to decide vs what the PM can specify.
What you can build with this
Backend feature ready to scope
PRD approved, now generate the tech spec so engineering can scope and start.
API design
New endpoint or breaking change to existing one — spec it before building.
Data migration
Schema change, table merge, field rename — write the migration plan up front.
PM-engineering pair
Co-write with a senior engineer. PM owns the product intent, eng owns the technical detail.
