An MVP is not only the smallest customer path. It is the smallest product a team can operate responsibly. If the user can submit a request but staff cannot correct, trace, secure, or recover it, the product is incomplete.
1. Roles and permission boundaries
List every user and staff role, the records each may see, the actions each may take, and sensitive actions requiring additional approval. Include service accounts and support impersonation. Test record-level isolation, not only page access.
2. Durable data model
Define stable identifiers, relationships, required fields, status values, uniqueness, timestamps, source, and deletion behavior. Decide what happens when the same real-world person or object enters twice. Preserve enough history to explain consequential state changes.
3. Staff operating surface
Provide the smallest safe back office: queue, search, filters, ownership, record detail, correction, state transition, notes, and export. A spreadsheet can be an intentional temporary operating surface, but only if access, identifiers, sync, errors, and ownership are defined.
4. Exception states
Map invalid input, duplicate submission, failed payment, failed notification, provider outage, manual review, cancellation, retry, and partial completion. Give every uncertain state a visible owner and recovery action.
5. Notifications as delivery workflows
For each email, SMS, push, or in-app message, define trigger, recipient, template version, sensitive content limits, provider result, retry, duplicate prevention, unsubscribe or preference behavior where applicable, and staff visibility. Do not mark the business workflow complete merely because a send request was accepted.
6. Audit and support context
Record the actor, action, target ID, time, result, and relevant version for important changes. Give support a way to locate a user-visible event without exposing secrets or unrelated customer data. Add a correlation ID across client, backend, and provider logs.
7. Security acceptance criteria
Write testable requirements for authentication, session handling, authorization, input validation, secrets, encryption in transit, sensitive data, dependencies, logging, rate limits, and administrative actions. The OWASP Application Security Verification Standard can help structure web-application requirements; select controls appropriate to the product and risk rather than claiming compliance by reference.
8. Data lifecycle and privacy
For each field, identify purpose, source, access, external processors, retention, correction, export, and deletion. Avoid collecting data that the first release cannot protect or use. Define what happens in logs, analytics, backups, and test environments as well as the primary database.
9. Backup and recovery
Specify what is backed up, frequency, retention, encryption, access, and restore procedure. Perform a restore test that proves records, relationships, files, and configuration recover together. A provider’s backup checkbox is not a recovery test.
10. Metrics tied to the outcome
Measure the useful outcome and failure points: complete requests, valid handoffs, time to owner, corrections, duplicate actions, abandoned steps, provider failures, and support volume. Avoid adding analytics events that collect more personal data than the decision requires.
11. Environments and release controls
Separate production configuration and secrets from development. Define schema migration, feature flags, provider test modes, release approval, health checks, monitoring, rollback, and ownership. Record which external account or credential can block release.
12. Commercial and support completion
Include terms and privacy pages, contact route, billing boundaries where applicable, cancellation, data export, status communication, and a process for security reports. These are product functions, not launch-week decoration.
Minimum acceptance matrix
| Area | Acceptance evidence | Owner |
|---|---|---|
| Golden path | User completes the intended outcome and staff completes the operating action | Product |
| Authorization | Allowed and denied role tests pass at API and record level | Engineering or platform owner |
| Failure | Provider failure is visible, recoverable, and does not duplicate work | Operations |
| Recovery | Verified restore and release rollback meet the defined objective | Technical owner |
| Support | Staff can locate, explain, and correct a representative issue | Support lead |
| Exit | Core records and files export in a usable form | Business owner |
Scope by removing breadth, not foundations
Reduce the number of user types, workflows, integrations, platforms, and edge options. Do not remove authorization, staff ownership, error visibility, backups, or a support path from a workflow that remains.
Use the no-code scorecard to prove that a platform can support this backend. Use the web-versus-mobile decision guide to choose the smallest client surface without rebuilding the product model.
Use the data retention policy guide to turn lifecycle requirements into triggers and deletion evidence, then apply the small-business security baseline to the systems that operate the product.
