Delivery Planning - Realistic Roadmap with Critical Path

Foundational Principle

Every roadmap must be grounded in reality, not optimism.

Creating unrealistic timelines creates:

• Broken promises to stakeholders
• Team burnout from impossible deadlines
• Loss of credibility when dates slip
• Hidden dependencies discovered during execution

Roadmaps answer: When will working software be delivered to users? Roadmaps never answer: How fast could we go if everything goes perfectly (that's fantasy).

Mandatory Workflow

Explicit Rules

✅ DO Include in Roadmap

Start/end dates (YYYY-MM-DD format), team composition (N devs, roles), velocity multiplier (custom or default), critical path (longest dependency chain), parallel streams (independent task groups), delivery goals (what ships each period), period boundaries (sprint/cycle start/end dates), spill over identification (tasks crossing period boundaries), resource allocation (who works on what), risk milestones (high-impact dependencies), contingency buffer (10-20% for unknowns), Definition of Done per delivery period

❌ NEVER Include in Roadmap

Best-case scenarios ("if everything goes perfectly"), optimistic estimates ("assuming no blockers"), undefined capacity ("we'll figure it out"), missing dependencies ("tasks are independent"), unrealistic parallelization ("everyone works on everything"), no buffer time ("ship on last day"), vague milestones ("feature mostly done"), assumed availability ("team always at 100%"), fixed cadence without asking user, period boundaries ignored (tasks don't respect sprint/cycle limits)

Rationalization Table

Red Flags - STOP

If you catch yourself doing any of these, STOP and ask the user:

• Estimating without knowing team size
• Assuming all developers are equally skilled
• Ignoring task dependencies when building timeline
• Using fixed cadence without asking (sprint/cycle/continuous)
• Missing period start date when user chose sprint/cycle
• Missing period duration when user chose sprint/cycle
• Scheduling tasks without checking blockers
• Assuming 100% capacity (no meetings, no interruptions)
• Using velocity multiplier without offering customization
• Using round numbers for dates ("exactly 4 weeks")
• Missing contingency buffer
• Not checking if tasks fit within period boundaries
• No clear definition of "done" per delivery period
• Ambiguous priorities (which task first if both ready?)

When you catch yourself: Use AskUserQuestion to resolve ambiguity with the user.

Mandatory User Questions

Use AskUserQuestion tool to gather these REQUIRED inputs:

Question 1: Start Date

• Header: "Start Date"
• Question: "When will the team start working on this feature?"
• Format: YYYY-MM-DD (e.g., 2026-03-01)
• Why: Determines all subsequent dates in the roadmap

Question 2: Team Composition

• Header: "Team Size"
• Question: "How many developers will work on this feature?"
• Options:

- "1 developer (solo)" - Single developer - "2 developers (pair)" - Small team - "3-4 developers (squad)" - Full squad - "5+ developers (large team)" - Large team

• Why: Determines parallelization capacity and resource allocation

Question 3: Delivery Cadence

• Header: "Delivery Cadence"
• Question: "How does your team organize delivery cycles?"
• Options:

- "Sprints (1-2 weeks)" - Scrum-style fixed iterations - "Cycles (1-3 months)" - Shape Up-style longer cycles - "Continuous (no fixed intervals)" - Kanban-style continuous delivery

• Why: Determines how to group tasks and define delivery milestones

Question 4 (CONDITIONAL): Sprint/Cycle Configuration

• When to ask: If user chose "Sprints" or "Cycles" in Question 3
• Part A - Duration:

- Header: "Period Duration" - Question (if Sprints): "What is your sprint duration?" - Options: "1 week", "2 weeks" - Question (if Cycles): "What is your cycle duration?" - Options: "1 month (4 weeks)", "2 months (8 weeks)", "3 months (12 weeks)" - Why: Determines period boundaries for task allocation

• Part B - Start Date:

- Header: "Period Start" - Question (if Sprints): "When does Sprint 1 start?" (format: YYYY-MM-DD) - Question (if Cycles): "When does Cycle 1 start?" (format: YYYY-MM-DD) - Why: Establishes period boundaries to check if tasks fit completely or spill over

• Note: If user chose "Continuous", skip this question (no fixed periods)

Question 5: Human Validation Overhead

Context:

• Baseline: AI Agent implements via ring:dev-cycle
• AI handles: coding, TDD, automated review, SRE validation, DevOps
• AI Estimate: X AI-agent-hours (from tasks.md)

Question: "What overhead for human validation and adjustments?"

Options:

1. "1.2x - Minimal validation (20% overhead)"

- AI generates consistently high-quality code - Quick review, minimal adjustments - Example: 4h AI → 4.8h adjusted → 5.3h calendar

1. "1.5x - Standard validation (50% overhead)" ← RECOMMENDED

- Normal review process with some adjustments - Re-run tests after changes - Standard manual QA - Example: 4h AI → 6h adjusted → 6.67h calendar

1. "2.0x - Deep validation (100% overhead)"

- Critical review with multiple rounds - Significant refactoring requested - Extensive manual testing - Example: 4h AI → 8h adjusted → 8.89h calendar

1. "2.5x - Heavy rework (150% overhead)"

- AI code needs major changes - Multiple iteration cycles - Complex stakeholder feedback - Example: 4h AI → 10h adjusted → 11.11h calendar

1. "Custom multiplier"

- Specify value based on historical data - Example: 1.7x, 1.8x, etc.

Multiplier accounts for:

• Human code review time (validation, not execution)
• Requested adjustments and refactoring
• Manual exploratory testing
• Stakeholder demos and feedback
• Documentation review
• Deployment validation

Historical data (update after tasks): After completing tasks, track actual multipliers:

• Task T-001: Planned 1.5x, Actual 1.6x (close)
• Task T-002: Planned 1.5x, Actual 2.1x (underestimated)
• Average: 1.7x → Adjust future estimates

Question 6 (CONDITIONAL): Priority Clarification

• When to ask: If multiple tasks have same dependencies and could start simultaneously
• Header: "Task Priority"
• Question: "Tasks T-XXX and T-YYY are both ready. Which should start first?"
• Options: [List the competing tasks with their descriptions]
• Why: Prevents arbitrary sequencing decisions

Question 7 (CONDITIONAL): Capacity Confirmation

• When to ask: If team size seems insufficient for parallelization opportunities
• Header: "Capacity Constraint"
• Question: "Critical path is X weeks, but with N more devs we could parallelize and finish in Y weeks. Do you want to:"
• Options:

- "Keep current team (X weeks)" - Accept longer timeline - "Add resources (Y weeks)" - Shorten timeline with more people

• Why: User decides cost vs. speed tradeoff

Gate 9/4 Validation Checklist

Gate Result: ✅ PASS → Ready for execution | ⚠️ CONDITIONAL (adjust capacity/dates) | ❌ FAIL (unrealistic, rework)

Velocity Calibration (Lerian Standard)

See shared-patterns/ai-agent-baseline.md for baseline definition.

Baseline: AI Agent via ring:dev-cycle Capacity: 90% (hardcoded) Multiplier: User-defined (human validation overhead)

Calculation Formula

adjusted_hours = ai_estimate × multiplier
calendar_hours = adjusted_hours ÷ 0.90
calendar_days = calendar_hours ÷ 8 ÷ team_size

Where:
- ai_estimate = from tasks.md (AI-agent-hours)
- multiplier = human validation overhead (typically 1.2x - 2.5x)
- 0.90 = capacity utilization (90%)
- 8 = hours per working day
- team_size = number of developers

Capacity Utilization: 90% (Fixed)

See shared-patterns/ai-agent-baseline.md for detailed capacity breakdown.

Summary: AI Agent has 90% capacity (10% overhead from API limits, context loading, tool execution).

Multiplier: Human Validation Overhead

User selects multiplier to account for:

• ✅ Human code review and validation time
• ✅ Requested adjustments and refactoring
• ✅ Re-running tests after changes
• ✅ Manual exploratory testing (beyond automated)
• ✅ Stakeholder demos and feedback cycles
• ✅ Deployment validation and monitoring setup
• ✅ Integration issues found in staging/production

Does NOT account for (already done by AI):

• ❌ Initial code implementation
• ❌ Unit/integration test writing (TDD)
• ❌ Automated code review (ring:code-reviewer)
• ❌ SRE validation (ring:sre)
• ❌ DevOps setup (ring:devops-engineer)

Example Calculation

Task T-001: "User Management CRUD API"

Step 1: AI Estimation (Gate 7)
AI Estimate: 4.5 AI-agent-hours

Step 2: Apply Multiplier (Gate 9)
User selects: 1.5x (standard validation)
Adjusted Hours: 4.5h × 1.5 = 6.75h

Step 3: Apply Capacity (hardcoded)
Calendar Hours: 6.75h ÷ 0.90 = 7.5h

Step 4: Convert to Days
Calendar Days: 7.5h ÷ 8h/day = 0.94 developer-days

Step 5: Account for Team Size
With 1 dev: 0.94 ÷ 1 = 0.94 calendar days ≈ 1 day
With 2 devs: 0.94 ÷ 2 = 0.47 calendar days ≈ 0.5 day (4 hours)

Breakdown of 7.5h total:

• AI implementation: 4.5h (60%)
• Human validation: 2.25h (30%) ← multiplier overhead
• Technical overhead: 0.75h (10%) ← capacity overhead

Period Boundary Calculation

For Sprints/Cycles:

1. Define period boundaries: Sprint 1: Start date to (Start date + Duration) Sprint 2: (Sprint 1 End + 1 day) to (Sprint 1 End + Duration + 1 day)...
2. Check task fit: Task T-001: Start: 2026-03-01 (based on dependencies) Duration: 10 calendar days End: 2026-03-10 Sprint 1: 2026-03-01 to 2026-03-14 (2 weeks) Fit check: T-001 end (2026-03-10) <= Sprint 1 end (2026-03-14) Result: ✅ Fits completely in Sprint 1
3. Identify spill overs: Task T-002: Start: 2026-03-10 (depends on T-001) Duration: 12 calendar days End: 2026-03-22 Sprint 1: 2026-03-01 to 2026-03-14 Sprint 2: 2026-03-15 to 2026-03-28 Fit check: T-002 end (2026-03-22) > Sprint 1 end (2026-03-14) Result: ⚠️ Spill over (starts Sprint 1, ends Sprint 2) Allocation: - Sprint 1: 4 days of work (2026-03-10 to 2026-03-14) - Sprint 2: 8 days of work (2026-03-15 to 2026-03-22)

For Continuous Delivery:

• No period boundaries to check
• Tasks scheduled based purely on dependencies and capacity
• Milestones defined by task completion, not time boxes

Critical Path Analysis

Definition: The longest chain of dependent tasks from start to finish.

How to Calculate:

1. Build dependency graph from tasks.md
2. For each task, calculate: Earliest Start Date (ESD) based on dependencies
3. For each task, calculate: Latest Start Date (LSD) without delaying project
4. Tasks where ESD = LSD are on critical path (zero slack)
5. Sum durations of critical path tasks = minimum project duration

Example:

Dependency Chain:
T-001 (Foundation, 2 weeks)
  → T-002 (API Layer, 1 week)
  → T-007 (Integration, 2 weeks)

Critical Path Duration: 2 + 1 + 2 = 5 weeks (minimum possible)

Parallel Stream (not on critical path):
T-005 (Frontend, 2 weeks) - can run parallel to T-001/T-002

Parallelization Analysis

Identify Independent Streams:

1. Tasks with no shared dependencies can run in parallel
2. Tasks requiring different skill sets can run in parallel
3. Tasks on different components can run in parallel

Constraints:

• Team size limits parallel streams (2 devs = max 2 parallel tasks)
• Skill requirements limit parallelization (backend vs. frontend)
• Integration points require synchronization (streams merge)

Example:

Stream A (Backend):  T-001 → T-002 → T-007
Stream B (Frontend): T-005 → T-006 (runs parallel to A)
Stream C (Infra):    T-009 (blocks both A and B, must run first)

With 3 devs: Can run A, B, C in parallel (optimal)
With 2 devs: Must sequence B after A (sub-optimal)
With 1 dev:  Fully sequential (slowest)

Section 3: Critical Path Analysis

## Critical Path Analysis

**Path:** T-001 → T-002 → T-007

| Task | Duration | Cumulative | Slack | On Critical Path? |
|------|----------|------------|-------|-------------------|
| T-001 | 2 weeks | 2 weeks | 0 days | ✅ Yes |
| T-002 | 1.5 weeks | 3.5 weeks | 0 days | ✅ Yes |
| T-007 | 2 weeks | 5.5 weeks | 0 days | ✅ Yes |
| T-005 | 1 week | 1 week | 2 weeks | ❌ No (parallel) |

**Minimum Project Duration:** 5.5 weeks (critical path)
**With Parallelization:** 5.5 weeks (no impact, T-005 has slack)
**Risk:** Any delay on critical path tasks delays entire project

**Spill Over Impact (for Sprint/Cycle cadences):**
- T-002 spills from Sprint 1 to Sprint 2 (4 days + 8 days)
- This affects Sprint 1 velocity reporting (partial completion)

Section 4: Resource Allocation

## Resource Allocation

| Role | Count | Utilization | Assigned Tasks |
|------|-------|-------------|----------------|
| Backend Engineer | 2 | 75% | T-001, T-002, T-003, T-007 |
| Frontend Engineer | 1 | 70% | T-005, T-006 |
| DevOps Engineer | 1 | 50% (part-time) | T-009 (infra setup) |
| QA Analyst | 1 | 60% (from Week 3) | Testing from Week 3 onwards |

**Bottlenecks:**
- Backend heavy: 4 tasks require backend skills (T-001, T-002, T-003, T-007)
- Frontend light: 2 tasks require frontend skills (T-005, T-006)

**Recommendations:**
- Consider cross-training if backend becomes bottleneck
- QA can start test planning during Week 1-2
- Frontend can assist with integration testing during T-007

Section 5: Risk Milestones

## Risk Milestones

| Milestone | Date | Risk Level | Impact | Mitigation |
|-----------|------|------------|--------|------------|
| Database Foundation (T-001) | Week 2 | 🔴 HIGH | Blocks T-002, T-003, T-007 (entire backend) | Start T-001 immediately, daily progress checks |
| API Integration (T-007) | Week 5.5 | 🟡 MEDIUM | Blocks deployment, but frontend can continue | Buffer time added, fallback: mock API |
| Sprint 1 Spill Over (T-002) | Sprint 1 end | 🟡 MEDIUM | Affects Sprint 1 velocity, team morale | Communicate spill over upfront, adjust Sprint 2 capacity |
| External Dependency (T-009) | Week 1 | 🟡 MEDIUM | Blocks deployment setup | Contact vendor early, have backup provider |

**Contingency Plan:**
- If T-001 slips by >2 days → Escalate to stakeholders, consider adding resource
- If T-007 blocked → Deploy frontend with mock backend, continue integration in next period
- If spill overs accumulate → Re-plan delivery cadence (extend sprint/cycle duration)

Section 7: Assumptions and Constraints

## Assumptions

1. **Team Availability:** All developers available full-time (no vacations, no split focus)
2. **Dependency Resolution:** All external dependencies (APIs, credentials) available on time
3. **Scope Stability:** No scope changes during execution (new requirements = new planning)
4. **Infrastructure Ready:** Development/staging environments available Day 1
5. **Capacity Utilization:** 90% (AI Agent via ring:dev-cycle, 10% overhead for API/technical)
6. **Multiplier Accuracy:** Custom multiplier ({X}x) validated against historical validation overhead OR using default multiplier (1.5x)
7. **Period Boundaries:** Sprint/Cycle boundaries do not shift (dates fixed)
8. **Baseline Execution:** All implementation via ring:dev-cycle (AI Agent with automated gates)

## Constraints

1. **Team Size:** N developers (cannot increase mid-project without re-planning)
2. **Fixed Scope:** All tasks from tasks.md must be completed (no cutting features)
3. **Quality Gates:** All ring:dev-cycle gates must pass (cannot skip review/testing)
4. **Critical Path:** Cannot compress critical path without adding resources or cutting scope
5. **Delivery Cadence:** {Sprint/Cycle/Continuous} rhythm cannot change mid-project
6. **Spill Over Management:** Tasks crossing period boundaries must be tracked explicitly

Common Violations

Confidence Scoring

Total Score Interpretation:

• 80-100 points: HIGH confidence - Roadmap is realistic and achievable
• 50-79 points: MEDIUM confidence - Some assumptions, monitor closely
• 0-49 points: LOW confidence - Significant unknowns, high risk of slippage

Action Based on Score:

• HIGH (80+): Proceed with execution, communicate dates to stakeholders
• MEDIUM (50-79): Present roadmap with caveats, identify assumptions to validate early
• LOW (<50): DO NOT commit to dates, resolve unknowns first via AskUserQuestion

Output & After Approval

Output to:

• docs/pre-dev/{feature-name}/delivery-roadmap.md — Human-readable roadmap (existing behavior)
• docs/pre-dev/{feature-name}/delivery-roadmap.json — Machine-readable structured data (see JSON Output Schema)

MUST generate both files. The MD is for humans to read; the JSON is for programmatic consumption by tools (e.g., lerian-map). The JSON MUST be generated alongside the MD every time — it is not optional.

Topology-aware output paths:

After user approves roadmap:

1. ✅ Roadmap becomes execution baseline
2. 📊 Track progress against delivery goals (not individual subtasks)
3. 🚨 Flag slippage early (daily standup: on track vs. critical path?)
4. 🔄 Re-plan if major assumptions break (scope change, resource loss, dependency block)
5. 📈 Update roadmap when tasks complete (mark done, adjust future periods)
6. ⚠️ Monitor spill overs (if sprint/cycle): communicate impact to stakeholders

Integration with dev-team:

• Use /ring:worktree to create isolated workspace
• Use /ring:dev-cycle to execute tasks with AI-assisted gates
• Use roadmap to prioritize which tasks to pull next

JSON Output Schema (MANDATORY)

MUST generate delivery-roadmap.json with this EXACT schema every time a delivery roadmap is created.

The JSON provides a stable, predictable contract for programmatic consumers. Unlike the MD (which has flexible formatting for human readability), the JSON MUST follow this schema exactly — field names, types, and structure are non-negotiable.

Field Reference

Validation Rules

MUST validate the JSON before writing:

1. dates.startDate and dates.endDate are REQUIRED — MUST NOT be empty or null
2. tasks array MUST have at least 1 item — empty roadmap is invalid
3. Every task MUST have id, description, aiEstimate, adjusted, calendar, days — these fields match lerian-map's RoadmapTask interface exactly
4. confidenceScore MUST be 0-100 — matches the scoring rubric in this skill
5. milestones array MUST have at least 1 item — every roadmap has at least one delivery milestone
6. criticalPath.taskIds MUST reference valid task IDs — all IDs must exist in tasks[]
7. version MUST be "1.0.0" — update when schema changes
8. milestones[].taskIds MUST reference valid task IDs from tasks[]
9. milestones[].spillOvers MUST reference valid task IDs from tasks[]
10. risks[].taskIds MUST reference valid task IDs from tasks[]
11. velocity.teamSize MUST be greater than 0 — zero team size causes division-by-zero

Continuous Cadence Rules

When deliveryCadence.type is "continuous", the following rules apply:

• deliveryCadence.periodDuration MUST be null
• deliveryCadence.periodStartDate MUST be null
• milestones[].type MUST be "milestone" (not "sprint" or "cycle")
• milestones[].startDate MUST be the earliest start date of any task in that milestone's taskIds

Anti-Rationalization (JSON Output)

Pressure Resistance Scenarios

Scenario 1: User Pushes for Faster Timeline

Scenario 2: User Provides Incomplete Team Info

Scenario 3: User Wants Default Velocity Without Validation

Scenario 4: User Disagrees with Critical Path

Scenario 5: User Uncertain About Cadence

Scenario 6: User Concerned About Spill Overs

The Bottom Line

If you created a roadmap without asking about team composition, delivery cadence, period configuration, or velocity multiplier, delete it and start over.

Roadmaps are not educated guesses. Roadmaps are calculated schedules based on:

• Validated dependency chains (critical path analysis)
• Realistic team capacity (size × utilization × custom velocity)
• Explicit parallelization opportunities (independent task streams)
• Risk-adjusted timelines (contingency buffer for unknowns)
• Team-specific delivery rhythm (sprint/cycle/continuous)
• Period boundary awareness (tasks fit or spill over)

"We'll figure it out as we go" is not a roadmap. It's hope.

Questions that must be answered before committing dates:

1. When do we start? (start date)
2. Who is working on this? (team composition)
3. How do they work? (AI-assisted or traditional, default or custom velocity)
4. What rhythm do they follow? (sprint/cycle/continuous)
5. When do periods start? (if sprint/cycle: period start date + duration)
6. What must happen first? (critical path)
7. What can happen in parallel? (parallelization)
8. Where are the risks? (high-impact dependencies)
9. Which tasks cross period boundaries? (spill overs)

If any question is unanswered, STOP and ask the user.

Deliver realistic roadmaps. Respect team capacity. Respect period boundaries. Build trust through accuracy.

Standards Loading (MANDATORY)

This skill is a delivery planning skill and does NOT require WebFetch of language-specific standards.

Purpose: Delivery Planning transforms tasks into realistic schedules. Technical standards are irrelevant at this stage—they apply during implementation via ring:dev-cycle.

However, MUST load tasks.md (Gate 7) to access AI estimates, dependencies, and scope definitions.

Blocker Criteria - STOP and Report

Cannot Be Overridden

These requirements are NON-NEGOTIABLE:

• MUST gather ALL mandatory user questions before creating roadmap
• MUST NOT create roadmap without team composition
• MUST NOT assume delivery cadence (must ask user)
• MUST include contingency buffer (10-20%)
• MUST calculate critical path from dependency graph
• MUST identify and document spill overs for sprint/cycle cadences
• MUST use AI estimates from tasks.md (no manual guessing)
• CANNOT commit to dates without capacity analysis

Severity Calibration

When This Skill Is Not Needed

• Tasks (Gate 7) not validated → complete task breakdown first
• Proof-of-concept without delivery commitment
• Research/exploration work without deadline
• Planning phase only (no execution planned yet)
• Roadmap already exists and dates are still valid
