Use this template to scope a backend feature or integration. Short answers are enough. Mark unknowns explicitly. Use invented examples instead of confidential records; share access credentials separately through an agreed secure channel.

## 1. Outcome

- What should the client or user be able to do?
- How does the workflow operate today?
- What would count as a successful first release?

## 2. One complete workflow

- Who starts the action?
- What information do they provide?
- Which decisions, approvals, and system updates follow?
- What should happen if a step fails?

## 3. Existing systems

- Application and backend stack:
- Systems to connect:
- Public API documentation:
- Available test environments:
- Access still to be arranged:
- Expected data volume and acceptable delay:

## 4. Scope and ownership

- Backend work requested:
- Work handled by the agency:
- Work handled by the client:
- Repository and deployment ownership:
- Items explicitly outside this assignment:

## 5. Acceptance criteria

For each criterion, state an input, action, and expected result. Include failure cases.

- Given ..., when ..., then ...
- If the same action is repeated ...
- If a connected system is unavailable ...
- If a user lacks permission ...

## 6. Agency relationship

- Who is the main contact?
- May the engineering partner join client discussions?
- Which branding and confidentiality arrangements apply?
- Who reviews changes and accepts completed work?

## 7. Handover and support

- Setup instructions and API documentation needed:
- Required tests and release steps:
- Who monitors the system after release?
- Who handles incidents and later change requests?
- IP and support terms to address in the agreement:

## 8. Constraints and unknowns

- Target date and reason:
- Budget context, if known:
- External dependencies:
- Questions that need investigation before an estimate:
