Retrospective

AI project retrospectives are structured reviews of AI initiatives to extract learnings and improve future work — examining what worked, what didn't, and why, with special attention to AI-specific challenges like data quality, model behavior, and evaluation, enabling teams to systematically improve their AI development practices.

Why AI Retros Matter

• Learn from Failure: AI projects often fail in unexpected ways.
• Share Knowledge: Capture tacit knowledge explicitly.
• Improve Process: Fix systematic issues.
• Build Culture: Normalize learning from mistakes.
• Avoid Repetition: Don't make the same mistakes twice.

AI-Specific Challenges to Review

Data Issues:

- Data quality problems discovered late
- Labeling inconsistencies
- Data drift after deployment
- Insufficient training data
- Unexpected data distributions

Model Issues:

- Model performance vs. expectations
- Unexpected behaviors/edge cases
- Evaluation metric vs. real-world fit
- Inference costs vs. budget
- Model degradation over time

Process Issues:

- Scope creep during development
- Unclear success criteria
- Integration challenges
- Communication gaps (ML ↔ product)
- Timeline estimation errors

Retrospective Format

Standard Structure (60-90 minutes):

1. Set the Stage (5 min)
   - Purpose and rules
   - Confidentiality, blame-free zone

2. Gather Data (15 min)
   - Timeline of events
   - Key metrics and outcomes
   - Individual observations

3. What Worked Well (15 min)
   - Successes to repeat
   - Effective practices
   - Team strengths

4. What Didn't Work (20 min)
   - Challenges faced
   - Root cause analysis
   - AI-specific issues

5. Action Items (15 min)
   - Concrete improvements
   - Owners and timelines
   - Follow-up plan

Key Questions for AI Projects

Technical:

- Did we have the right data? How could we know earlier?
- Was our evaluation realistic? Any production surprises?
- Were our infrastructure assumptions correct?
- What would we measure differently?

Process:

- How accurate were our estimates?
- Did we have the right expertise?
- Where were communication gaps?
- What caused the biggest delays?

Outcome:

- Did we solve the right problem?
- How does user experience match expectations?
- What would we do differently from day one?
- Are there quick wins we're missing?

5 Whys for AI Issues

Example: Model performs worse in production:

Why 1: Model accuracy dropped in production
Why 2: Production data distribution differs from training
Why 3: We trained on historical data that's now outdated
Why 4: We didn't have monitoring for data drift
Why 5: Data monitoring wasn't part of our launch checklist

Root cause: No data monitoring process
Action: Add data drift monitoring to launch requirements

Documenting Learnings

- Issue 2: ...

## Key Learnings
1. Learning 1
2. Learning 2

## Action Items
| Action | Owner | Due Date | Status |

Best Practices

• Blameless: Focus on systems, not individuals.
• Timely: Do retros soon after project ends.
• Inclusive: Include all team members.
• Actionable: Every learning needs an action.
• Follow Through: Review past action items.

AI project retrospectives are how teams compound their learnings — the field moves fast and projects often fail in novel ways, so systematic reflection transforms individual project lessons into organizational capabilities.
