--- name: correct-course description: Use when handling sprint changes or scope adjustments. Analyzes change impacts, re-estimates affected stories, and adjusts sprint capacity using PRISM principles. version: 1.0.0

Correct Course Task

Purpose

Guide a structured response to change triggers using PRISM principles and PSP/TSP measurement:

• Analyze change impacts on epics, stories, and estimations
• Re-estimate affected stories using PROBE method
• Track velocity impact and adjust sprint capacity
• Maintain estimation accuracy through changes
• Document lessons learned for future estimation

Instructions

1. Initial Setup & Impact Assessment

Acknowledge Change & Measure Impact:

• Confirm the change trigger with user
• Load current sprint stories and their estimations
• Calculate potential velocity impact
• Identify stories requiring re-estimation

PSP/TSP Metrics to Consider:

• Current sprint velocity vs planned
• Stories completed vs in-progress
• Estimation accuracy to date
• Team capacity remaining

2. Analyze Change Using PRISM Principles

Predictability Impact:

• How does change affect sprint predictability?
• What estimations become invalid?
• Which dependencies are affected?

Resilience Considerations:

• Can we absorb change without sprint failure?
• What's our contingency capacity?
• Are critical path items affected?

Intentionality Check:

• Is change aligned with sprint goals?
• Does it support product vision?
• Should we defer to next sprint?

Sustainability Analysis:

• Team capacity to handle change
• Technical debt implications
• Long-term velocity impact

Maintainability Review:

• Code quality impact of rushed changes
• Documentation update needs
• Test coverage considerations

3. Re-estimate Affected Stories

For each affected story:

re_estimation:
  original_estimate:
    story_points: X
    size_category: Y
    hours: Z

  change_impact:
    scope_change: "+/-N%"
    complexity_change: "increased|decreased|same"
    risk_change: "higher|lower|same"

  new_estimate:
    story_points: X'
    size_category: Y'
    hours: Z'
    confidence: "high|medium|low"

  justification: "Clear explanation of estimate change"

4. Sprint Capacity Recalculation

sprint_metrics:
  original:
    total_points: X
    total_hours: Y
    team_capacity: Z

  after_change:
    total_points: X'
    total_hours: Y'
    team_capacity: Z'

  options:
    - absorb: "Take the hit, extend hours"
    - defer: "Move stories to next sprint"
    - swap: "Replace with smaller stories"
    - descope: "Reduce story scope"

5. Generate Sprint Change Proposal

Create proposal document with:

Executive Summary:

• Change description and trigger
• Impact on sprint goals
• Recommended path forward

Metrics Impact:

• Velocity change: X → Y points
• Capacity change: A → B hours
• Risk score change: Low → Medium
• Confidence level: 85% → 70%

Story-Level Changes: For each affected story:

• Original estimation
• New estimation with rationale
• Dependencies affected
• Risk mitigation needed

Team Considerations:

• Role reassignments needed
• Skill gaps identified
• Additional resources required
• Quality gate adjustments

Proposed Actions:

1. Specific story changes
2. Sprint backlog adjustments
3. Team assignment updates
4. Timeline modifications

6. Update Estimation History

Record in estimation-history.yaml:

change_events:
  - date: YYYY-MM-DD
    sprint: N
    trigger: "requirement change|bug|scope creep"
    stories_affected: [X.Y, X.Z]
    estimation_impact:
      total_points_change: +/-N
      accuracy_impact: "X%"
    lessons_learned: |
      - Specific insight about estimation
      - Pattern identified for future
    improvement_actions:
      - "Add buffer for similar changes"
      - "Update estimation proxies"

7. Team Communication

Sprint Adjustment Meeting Agenda:

1. Present change and impact (5 min)
2. Review estimation changes (10 min)
3. Discuss capacity options (10 min)
4. Team consensus on path (5 min)
5. Update assignments (5 min)

Key Messages:

• Data-driven decision making
• Transparency on impact
• Team empowerment to choose
• Learning opportunity captured

Success Criteria

• All affected stories re-estimated
• Sprint capacity recalculated
• Team consensus achieved
• Estimation history updated
• Lessons learned documented
• Sprint plan adjusted and communicated
