# Scrum Event Backlog Refinement > Transform PBIs into ready status for AI execution. Use when refining backlog items, splitting stories, or ensuring Definition of Ready.

Keep in mind `scrum.ts` is the **Single Source of Truth**. Use `scrum-dashboard` skill for maintenance. ## Basic Instructions Maintain the Product Backlog in `scrum.ts` by performing these actions, typically in this order: * **Add PBIs** * When: new features requested, bugs found, or tech debt identified * How: add `draft` PBIs in User Story format (see `user-story-format.md`) with minimal initial details * Why: keep Product Backlog fresh and relevant * **Remove PBIs** * When: obsolete, duplicated, or no longer valuable * How: delete from Product Backlog array * Why: keep backlog focused and manageable * **Inspect and adapt `ready` PBIs** * When: every Product Backlog Refinement * How: run Adaptation Check and revert to `refining` if needed * Why: adapt to latest insights * **Sort and prioritize PBIs** * When: new PBIs added or priorities change * How: place higher-value items first in the array * Why: ensure highest-value work is done first * **Refine PBIs to `ready`** * When: PBIs are `draft` or `refining` * How: follow Refinement Sub-steps below * Why: Sprint Planning requires `ready` PBIs that meet Definition of Ready ### Refinement Sub-steps Iterate over up to 5 PBIs in `draft` or `refining` status and perform these steps: 1. Inspect and adapt User Story format (see `user-story-format.md`) 2. Split/merge PBIs to smallest value-delivering units (see `splitting.md`) 3. Define acceptance criteria with executable verification commands 4. **Apply Increment Test (MANDATORY)** - see `increment.md`: - ❓ Can we show working software at Sprint Review? - ❓ Does a user/stakeholder benefit DIRECTLY? - ❓ Does it work WITHOUT another PBI completing first? - **If any answer is NO**: Merge with a value-delivering PBI or add to Definition of Done - Infrastructure-only work (CI/CD, dependencies, schemas) is NEVER a valid PBI 5. Optionally explore codebase to fill gaps (technical details can be discussed later in Sprint Planning) 6. Review against Definition of Ready 7. Update status: - `ready` if passing the review and AI can fill all gaps - remain `refining` if human help is needed Low-priority PBIs can stay in `draft` or `refining` longer even without details; focus on high-priority items first. ## Definition of Ready A PBI is `ready` when all these conditions are met: * **passes the Increment Test** (see `increment.md`) - delivers observable, user-facing value * executable without human intervention * follows User Story format * satisfies INVEST principles strictly Even `ready` PBIs must pass **Adaptation Check for Ready PBIs** in addition to the above before Sprint Planning. ### INVEST Principles (AI-Agentic) | Principle | AI-Agentic Interpretation | |-----------|---------------------------| | **Independent** | Can reprioritize freely, **AND** no human dependencies | | **Negotiable** | Clear outcome, flexible implementation | | **Valuable** | Can deliver increment specified as observable, user-facing benefit in User Story (see `increment.md`) | | **Estimable** | All information needed is available | | **Small** | Smallest unit delivering user value | | **Testable** | Has **executable verification commands** | ### Adaptation Check for Ready PBIs | Check | Question | If Failed | |-------|----------|-----------| | **Goal Alignment** | Still aligned with Product Goal? | Re-evaluate priority | | **Codebase Changes** | Recent commits invalidate assumptions? | Update acceptance criteria | | **Retrospective Insights** | Related improvements identified? | Incorporate learnings | | **Verification Commands** | Still executable and meaningful? | Update commands | | **Dependencies** | New blockers emerged? | Document and resolve | **If any check fails**: Change status back to `refining` and address gaps. ## Collaboration - **@agentic-scrum:scrum:team:scrum-team-product-owner**: Product Goal alignment, value prioritization - **@agentic-scrum:scrum:team:scrum-team-developer**: Technical feasibility, effort estimation - **@agentic-scrum:scrum:team:scrum-team-scrum-master**: Definition of Ready enforcement ## Reference Documents | Document | Use When | |----------|----------| | `user-story-format.md` | Writing or validating User Story format | | `splitting.md` | PBI is too large or too small | | `anti-patterns.md` | Checking for common PBI mistakes | | `increment.md` | Validating that PBI delivers demonstrable value | --- > Converted and distributed by [TomeVault](https://tomevault.io/claim/atusy) — claim your Tome and manage your conversions.
