Retrospective Analysis Skill

Purpose

Generate a data-grounded retrospective brief that separates facts from feelings, so the team spends retro time on solutions rather than debating what happened.

Required Inputs

• Sprint tickets: planned vs. completed
• Carry-over tickets and reasons
• Tickets reopened after closing
• Any incidents or unplanned work
• Sprint velocity vs. historical average

Process

1. Calculate: completion rate, carry-over rate, unplanned work percentage
2. Identify patterns: which ticket types were most likely to carry over? Which caused blockers?
3. Note any process or communication breakdowns visible in the data
4. Prepare 3 "Start / Stop / Continue" prompts based on the data — not generic, specific to this sprint
5. Suggest 1 concrete experiment for the next sprint based on the biggest friction point

Output Format

Sprint [Number] Retrospective Brief

By the Numbers:

• Planned: [n] tickets | Completed: [n] | Carry-over: [n] | Completion rate: [%]
• Unplanned work: [n] tickets ([%] of capacity)
• Velocity: [points] vs. [average] average

What the Data Suggests: [2-3 observations grounded in the numbers above]

Discussion Prompts:

• Start: [specific prompt]
• Stop: [specific prompt]
• Continue: [specific prompt]

Suggested Experiment for Next Sprint: [One concrete, testable process change]
