Defines the purpose, audience, boundaries, constraints, expected outcome, and acceptance criteria for feature prioritization. It fixes adoption boundaries and observable failure evidence while keeping environment-specific limits configurable.
Package status: reference context ready for human review. The contract and test scenarios are complete, but no claim is made that an adopting implementation has passed them.
Decision
For Feature prioritization, adopt a versioned product brief with named evidence owners. Make the user-visible promise, exclusions, authority, and failure response explicit while leaving measured thresholds as adoption choices. This requirements block focuses specifically on definition and scope. This package is a reference contract: the adopting team must choose numeric limits, providers, jurisdictions, and operational owners from evidence in its own environment.
Scope
- The Feature prioritization actors, inputs, outputs, states, policy or schema versions, and externally visible outcomes required for the definition and scope focus of this requirements block.
- Primary and alternate interfaces, background work, caches, integrations, support paths, and evidence that can exercise the same boundary.
- Adoption-specific configuration, rollout, recovery, and verification responsibilities needed to apply the reference safely.
Outside this block
- Choosing a universal vendor, framework, jurisdiction, numeric threshold, retention period, or service-level objective for every adopter.
- Claiming that packaged scenarios have run against a downstream implementation or that this reference grants legal, security, or accessibility certification.
Contract
- Distinguish observed evidence, explicit assumption, chosen constraint, and open question so a guess cannot silently become a requirement.
- Name target actors, situations, jobs, exclusions, current alternatives, expected outcome, and measurable signal.
- Keep MVP commitments, non-goals, later options, and irreversible decisions in separate lists with change rationale.
- Assign review dates and invalidation signals to material assumptions rather than treating discovery as permanently complete.
- State which actor receives which outcome under each material state, including unavailable, unauthorized, empty, and partial conditions.
- Mark configurable limits and policies as choices with owners; do not present sample values as universal requirements.
- Score a defined outcome against evidence for user reach, impact, confidence, effort, risk, strategic fit, obligations, dependencies, and opportunity cost using one visible decision period.
- Keep estimates and facts separate, record rejected and deferred reasons, account for capacity and sequencing constraints, and treat the score as decision support rather than an automatic commitment.
- For the definition and scope variant, enforce this declared boundary: defines the purpose, audience, boundaries, constraints, expected outcome, and acceptance criteria for feature prioritization.
Implementation guidance
- Review the contract with product, implementation, operations, security, and affected users before promoting it beyond review.
- Model Feature prioritization inputs, outputs, actors, states, invariants, side effects, and evidence before selecting framework or vendor details.
- Store the applicable Feature prioritization contract or policy version with material state so migrations, replay, and support decisions remain attributable.
- Introduce the path behind controlled rollout, compare expected and observed outcomes, and keep a tested recovery route until adoption evidence is complete.
Failure handling and safeguards
- When evidence contradicts the brief, mark the affected decision unresolved and stop dependent scope from being treated as approved.
- Invalid or contradictory Feature prioritization state is rejected or quarantined; the implementation never guesses a value that broadens authority or duplicates an effect.
- Retries are bounded and use durable identity; after exhaustion, work reaches an inspectable terminal state with an accountable owner.
Verification and operations
- Map each promise and exclusion to at least one observable scenario and confirm that no two states require contradictory outcomes.
- Monitor Feature prioritization success, denial, validation failure, dependency failure, retry exhaustion, and recovery by contract version without sensitive payload dimensions.
- Re-run paired positive and negative fixtures after policy, schema, dependency, migration, or boundary changes and preserve the resulting evidence.
Adoption assumptions
- Names and values in the example are a concrete fixture, not universal defaults; adopters replace them through documented evidence and ownership.
- The adopting system can provide authenticated identity, durable operation or record versions, bounded telemetry, and a controlled path for change.
The executable-looking examples in this package are fixtures and acceptance contracts. Run the collection validator to check structure and metadata, then translate and execute the scenarios in the target repository before recording implementation evidence.
