Backlog Health
Signs of Unhealthy Backlog
BACKLOG HEALTH CHECK:
┌─────────────────────────────────────────────────────────────┐
│ │
│ UNHEALTHY BACKLOG: │
│ ────────────────── │
│ ❌ 500+ items (nobody knows what's there) │
│ ❌ Oldest items from 2+ years ago │
│ ❌ Vague items ("Improve performance") │
│ ❌ No estimates on upcoming items │
│ ❌ No clear priority order │
│ ❌ Duplicate items │
│ ❌ Items no longer relevant │
│ ❌ Top items not ready for sprint │
│ │
│ ─────────────────────────────────────────────────────────── │
│ │
│ HEALTHY BACKLOG: │
│ ──────────────── │
│ ✅ Manageable size (50-100 items) │
│ ✅ Clear priority order │
│ ✅ Top 2-3 sprints refined and estimated │
│ ✅ Each item has clear acceptance criteria │
│ ✅ No duplicates │
│ ✅ Regular cleanup of stale items │
│ ✅ Stories small enough for a sprint │
│ ✅ Team understands top items │
│ │
│ ─────────────────────────────────────────────────────────── │
│ │
│ BACKLOG STRUCTURE: │
│ │
│ ┌─────────────────────────────────────────────────────────┐│
│ │ PRIORITY 1-10: REFINED (Next 2 sprints) ││
│ │ ─────────────────────────────────────── ││
│ │ • Estimated ││
│ │ • Acceptance criteria done ││
│ │ • Team understands ││
│ │ • Ready to pull ││
│ ├─────────────────────────────────────────────────────────┤│
│ │ PRIORITY 11-30: PARTIALLY REFINED (Coming soon) ││
│ │ ───────────────────────────────────────────── ││
│ │ • General understanding ││
│ │ • Needs final refinement ││
│ │ • Will be refined in next 1-2 weeks ││
│ ├─────────────────────────────────────────────────────────┤│
│ │ PRIORITY 31+: IDEAS/FUTURE ││
│ │ ────────────────────────── ││
│ │ • Rough ideas ││
│ │ • Not yet refined ││
│ │ • Review periodically ││
│ │ • Delete if stale ││
│ └─────────────────────────────────────────────────────────┘│

Grooming Activities
Regular Maintenance
BACKLOG GROOMING ACTIVITIES:
┌─────────────────────────────────────────────────────────────┐
│ │
│ WEEKLY REFINEMENT (with team): │
│ ─────────────────────────────── │
│ • Review upcoming stories │
│ • Clarify requirements │
│ • Write acceptance criteria │
│ • Estimate effort │
│ • Split large stories │
│ │
│ ─────────────────────────────────────────────────────────── │
│ │
│ PO ONGOING (async): │
│ ──────────────────── │
│ • Add new items as they arise │
│ • Prioritize/reorder │
│ • Write initial descriptions │
│ • Prepare for refinement │
│ • Gather context/designs │
│ │
│ ─────────────────────────────────────────────────────────── │
│ │
│ MONTHLY CLEANUP: │
│ ───────────────── │
│ • Review bottom of backlog │
│ • Delete stale items │
│ • Archive "won't do" items │
│ • Consolidate duplicates │
│ • Verify priorities still valid │
│ │
│ ─────────────────────────────────────────────────────────── │
│ │
│ QUARTERLY REVIEW: │
│ ────────────────── │
│ • Align backlog with roadmap │
│ • Major re-prioritization │
│ • Check if epics are on track │
│ • Review completed vs planned │
└─────────────────────────────────────────────────────────────┘
Story Splitting
BREAKING DOWN STORIES:
┌─────────────────────────────────────────────────────────────┐
│ │
│ WHY SPLIT: │
│ ────────── │
│ • Stories should fit in a sprint │
│ • Smaller = less risk, faster feedback │
│ • Easier to estimate accurately │
│ │
│ RULE OF THUMB: │
│ If estimate > 8 points, consider splitting │
│ │
│ ─────────────────────────────────────────────────────────── │
│ │
│ SPLITTING STRATEGIES: │
│ │
│ BY WORKFLOW: │
│ ┌─────────────────────────────────────────────────────────┐│
│ │ ORIGINAL: User management ││
│ │ ││
│ │ SPLIT: ││
│ │ 1. Create user ││
│ │ 2. View user list ││
│ │ 3. Edit user ││
│ │ 4. Delete user ││
│ │ 5. User roles/permissions ││
│ └─────────────────────────────────────────────────────────┘│
│ │
│ BY USER TYPE: │
│ ┌─────────────────────────────────────────────────────────┐│
│ │ ORIGINAL: Dashboard ││
│ │ ││
│ │ SPLIT: ││
│ │ 1. Admin dashboard ││
│ │ 2. Manager dashboard ││
│ │ 3. User dashboard ││
│ └─────────────────────────────────────────────────────────┘│
│ │
│ BY HAPPY PATH + EDGE CASES: │
│ ┌─────────────────────────────────────────────────────────┐│
│ │ ORIGINAL: Payment processing ││
│ │ ││
│ │ SPLIT: ││
│ │ 1. Successful credit card payment (happy path) ││
│ │ 2. Payment failure handling ││
│ │ 3. Retry logic ││
│ │ 4. Refund processing ││
│ └─────────────────────────────────────────────────────────┘│
│ │
│ EACH SPLIT SHOULD: │
│ • Deliver value independently │
│ • Be testable on its own │
│ • Be completable in one sprint │
└─────────────────────────────────────────────────────────────┘
Prioritization
Ordering the Backlog
PRIORITIZATION PROCESS:
┌─────────────────────────────────────────────────────────────┐
│ │
│ PRIORITIZATION FACTORS: │
│ │
│ 1. BUSINESS VALUE │
│ How much does this help users/business? │
│ Revenue impact, user satisfaction, strategic value │
│ │
│ 2. URGENCY │
│ How time-sensitive is this? │
│ Deadlines, dependencies, market timing │
│ │
│ 3. EFFORT │
│ How much work is this? │
│ High-value low-effort = quick wins │
│ │
│ 4. RISK │
│ What's the risk of not doing this? │
│ What's the risk of doing this? │
│ │
│ 5. DEPENDENCIES │
│ What must come before this? │
│ What's blocked by this? │
│ │
│ ─────────────────────────────────────────────────────────── │
│ │
│ WEIGHTED SHORTEST JOB FIRST (WSJF): │
│ │
│ WSJF = (Business Value + Time Criticality + Risk) / Effort │
│ │
│ ┌───────────────────────────────────────────────────────┐ │
│ │ STORY VALUE URGENCY RISK EFFORT WSJF │ │
│ │ ───── ───── ─────── ──── ────── ──── │ │
│ │ Login bug 9 10 8 2 13.5 ★ │ │
│ │ New report 7 5 3 8 1.9 │ │
│ │ Search fix 8 6 5 3 6.3 │ │
│ │ Dashboard 6 4 2 13 0.9 │ │
│ └───────────────────────────────────────────────────────┘ │
│ │
│ Higher WSJF = Higher priority │
└─────────────────────────────────────────────────────────────┘
Cleanup
Managing Backlog Size
BACKLOG CLEANUP:
┌─────────────────────────────────────────────────────────────┐
│ │
│ THE PROBLEM: │
│ Backlogs grow forever if not pruned │
│ Old items become irrelevant but never removed │
│ │
│ CLEANUP RULES: │
│ │
│ DELETE IF: │
│ ☐ No activity in 6+ months │
│ ☐ No one remembers why it was added │
│ ☐ Problem it solves no longer exists │
│ ☐ Duplicate of another item │
│ ☐ Superseded by other work │
│ │
│ ARCHIVE (NOT DELETE) IF: │
│ ☐ Good idea but not prioritized │
│ ☐ May be relevant in future │
│ ☐ Rejected by stakeholders for now │
│ │
│ ─────────────────────────────────────────────────────────── │
│ │
│ CLEANUP SESSION (Monthly): │
│ ┌─────────────────────────────────────────────────────────┐│
│ │ BACKLOG CLEANUP: January Review ││
│ │ ││
│ │ BEFORE: 287 items ││
│ │ ││
│ │ REVIEWED: ││
│ │ • Bottom 50 items (oldest/lowest priority) ││
│ │ ││
│ │ DECISIONS: ││
│ │ • Deleted: 12 (stale, irrelevant) ││
│ │ • Archived: 8 (good ideas, not now) ││
│ │ • Merged: 5 into existing items ││
│ │ • Keep: 25 (still valid) ││
│ │ ││
│ │ AFTER: 262 items ││
│ │ ││
│ │ NOTE: Focus on quality over quantity ││
│ │ A smaller, healthier backlog is better ││
│ └─────────────────────────────────────────────────────────┘│

│ "If it's been in the backlog for a year │
│ and we haven't done it, do we really need it?" │
