Action Items, Experiments, Measurement, and Retro Anti-Patterns
Retrospective Experiments, Actions, and Follow-Through
Mengubah insight retrospective menjadi eksperimen yang terukur.
Part 024 — Action Items, Experiments, Measurement, and Retro Anti-Patterns
Positioning
Retrospective hanya menghasilkan value jika insight berubah menjadi tindakan, tindakan dijalankan, dan hasilnya diinspeksi.
Masalah umum:
- action terlalu banyak;
- action terlalu besar;
- owner tidak jelas;
- action tidak masuk workflow;
- dan hasil tidak pernah diukur.
Core thesis: improvement action yang baik adalah eksperimen kecil dengan hypothesis, owner, success signal, review date, dan keputusan setelah evidence tersedia.
1. From Insight to Action
Flow improvement yang sehat:
Action tanpa hypothesis mudah berubah menjadi activity tanpa learning.
2. Action Item versus Experiment
Action item
A task to complete.
Example:
Add review checklist.
Experiment
A change tested to see whether it improves a condition.
Example:
For two Sprints, use a review checklist on contract-changing PRs and measure review rework plus escaped compatibility defects.
Experiments are stronger for process improvement.
3. Good Improvement Hypothesis
Structure:
We believe:
By changing:
We expect:
We will know when:
Example:
We believe review latency is driven by oversized PRs.
By limiting PRs to one coherent change and using stacked PRs,
we expect median first-review time to drop.
We will know when median review latency is below one working day for two Sprints.
4. Characteristics of a Good Retro Action
- small;
- specific;
- owned;
- observable;
- time-bounded;
- within influence;
- and connected to insight.
Avoid:
- “communicate better”;
- “be more careful”;
- “improve quality”;
- or “fix process”.
5. Action Scope
Good actions fit within a short horizon.
Prefer:
- one or two experiments;
- one clear owner;
- and one review point.
Too many actions dilute follow-through.
6. Action Ownership
Owner is accountable for moving the action, not doing everything personally.
Owner may:
- coordinate;
- gather evidence;
- update status;
- and bring result back.
Shared ownership without named owner often means no ownership.
7. Team-Owned versus External Actions
Team-owned
Within team authority.
Example:
- change Daily Scrum format;
- introduce WIP limit;
- rotate reviewer.
External
Requires organization or another team.
Example:
- environment capacity;
- release policy;
- security approval SLA.
External action needs:
- sponsor;
- escalation;
- evidence;
- and checkpoint.
8. Action Tracking
Track actions where normal work is visible.
Possible locations:
- Sprint Backlog;
- improvement backlog;
- team board;
- working agreement;
- or engineering backlog.
Avoid retro notes that no one revisits.
9. Improvement Backlog
An improvement backlog can contain:
- process experiment;
- tooling improvement;
- technical debt;
- team enablement;
- and organizational impediment.
It still needs ordering.
Do not create a second graveyard backlog.
10. Action Priority
Prioritize based on:
- impact;
- recurrence;
- feasibility;
- risk reduction;
- and team authority.
Impact-effort lens
High impact / low effort:
Do first.
High impact / high effort:
Create staged experiment.
Low impact / low effort:
Optional.
Low impact / high effort:
Avoid.
11. Success Signals
A success signal should be observable.
Examples:
- review latency;
- cycle time;
- carry-over;
- blocked duration;
- defect rate;
- flaky test rate;
- meeting duration;
- response rate;
- and qualitative team feedback.
Use one or two signals, not a dashboard for every action.
12. Baseline
Before experiment, capture current condition.
Example:
Baseline:
Median review latency = 2.8 days
90th percentile = 5.1 days
Without baseline, improvement claim is subjective.
13. Leading and Lagging Signals
Leading
- WIP reduced;
- review response faster;
- examples added earlier.
Lagging
- fewer defects;
- lower carry-over;
- improved predictability.
Short experiments often rely on leading indicators first.
14. Qualitative Evidence
Not all improvements are numeric.
Qualitative signals:
- team reports clearer ownership;
- stakeholder confusion decreases;
- fewer repeated clarification questions;
- and support reports easier diagnosis.
Document source and sample.
15. Experiment Duration
Set enough time to observe.
Examples:
- one Sprint for meeting format;
- two to four Sprints for flow policy;
- longer for defect trend.
Avoid judging complex outcomes too quickly.
16. Adoption Decision
After experiment:
Adopt
Evidence supports change.
Adapt
Some benefit, but mechanism needs adjustment.
Abandon
No benefit or cost too high.
Extend
Evidence insufficient.
Always record the decision.
17. Action Review Cadence
At the start of Retrospective:
- review prior actions;
- inspect evidence;
- decide status;
- and close or adapt.
This reinforces trust.
18. Definition of Done for Improvement Action
Example:
- Experiment executed.
- Evidence captured.
- Team reviewed result.
- Decision recorded.
- Working agreement or backlog updated.
“Checklist created” is not complete if no one tested it.
19. Working Agreement Update
If experiment becomes standard practice:
- update working agreement;
- communicate;
- and review later.
This turns learning into durable team memory.
20. Automation of Improvement
When action is validated, automate where useful.
Examples:
- PR size warning;
- contract test in CI;
- aging alert;
- deployment evidence;
- and environment health check.
Automation reduces reliance on memory.
21. Retrospective Action Anti-Patterns
Too many actions
Nothing finishes.
Vague action
No observable change.
No owner
No follow-through.
Permanent action without experiment
Process burden grows.
Metric-only action
Behavior not understood.
Action outside authority
No sponsor.
Action hidden in notes
No visibility.
Repeated restart
Same idea introduced every Sprint.
22. “Communicate Better” Anti-Pattern
Rewrite into mechanism.
Weak:
Communicate blockers better.
Better:
Mark blocked items immediately, include owner and next checkpoint, and escalate after one working day.
23. “Be More Careful” Anti-Pattern
Weak:
Be more careful with event changes.
Better:
Add provider-consumer compatibility test to CI for event-schema changes.
System control is stronger than attention demand.
24. “Add More Meetings” Anti-Pattern
Meetings can help, but often add coordination cost.
Before adding:
- what decision is missing;
- who needs to attend;
- why async fails;
- and when meeting can be removed.
25. “Create a Checklist” Anti-Pattern
Checklist helps only if:
- used at decision point;
- concise;
- owner clear;
- and integrated with workflow.
A document in a wiki is not behavior change.
26. Action Overload
Action capacity is limited.
Improvement work competes with feature work.
Make it visible and ordered.
If leadership expects improvement without capacity, that contradiction should be escalated.
27. Improvement Capacity
Possible models:
- one experiment per Sprint;
- explicit improvement item;
- fixed small capacity;
- or opportunistic low-cost changes.
Choose based on context.
28. Technical Improvement Experiments
Examples:
- smaller PRs;
- contract test;
- faster CI stage;
- flaky-test quarantine policy;
- local environment script;
- and deployment automation.
Connect to flow or risk.
29. Process Improvement Experiments
Examples:
- right-to-left Daily Scrum;
- refinement pre-read;
- WIP limit;
- review rotation;
- and blocker escalation threshold.
30. Collaboration Experiments
Examples:
- pairing rotation;
- Three Amigos;
- async handoff template;
- and decision-log practice.
31. Product Collaboration Experiments
Examples:
- outcome statement on top backlog items;
- customer evidence in refinement;
- review feedback classification;
- and Product Goal check in Planning.
32. Remote-Team Experiments
Examples:
- written daily update before overlap;
- meeting-free focus block;
- recorded technical walkthrough;
- and timezone handoff checklist.
Measure communication delay and meeting load.
33. Organizational Improvement Experiments
Harder because authority is external.
Use:
- evidence;
- sponsor;
- narrow pilot;
- and explicit decision.
Example:
Pilot expedited architecture review for low-risk additive API changes using a predefined checklist.
34. Experiment Risk
An improvement experiment can cause harm.
Assess:
- delivery disruption;
- quality risk;
- team burden;
- stakeholder confusion;
- and reversibility.
Prefer reversible experiments.
35. Guardrails
Example WIP-limit experiment guardrails:
- expedite policy remains;
- production incident exempt;
- Product Owner informed;
- and review after two Sprints.
36. Metrics Misuse
Do not use improvement metrics to evaluate individuals.
Examples of misuse:
- reviewer ranking;
- developer cycle time;
- number of comments;
- or ticket throughput per person.
Measure system behavior.
37. Statistical Humility
Small teams have noisy data.
Do not claim causation from one Sprint.
Use:
- trend;
- qualitative context;
- and repeated observation.
38. Improvement Theatre
Signals:
- action list grows;
- many workshops;
- no behavior change;
- dashboards created but not used;
- and process complexity increases.
Improvement should reduce pain, not create ceremony.
39. Follow-Through Failure Modes
Owner unavailable
No backup or sponsor.
Action blocked externally
No escalation.
Measurement missing
No result.
Team forgets
Not in workflow.
Action too large
Never completes.
Incentive conflict
Behavior reverts.
40. Action Escalation
For external impediment, use:
Observed issue:
Frequency:
Impact:
Evidence:
Attempted mitigation:
Requested change:
Sponsor:
Decision date:
41. Senior Engineer Operating Model
Select leverage
Choose action that changes system behavior.
Avoid overengineering
Do not turn every improvement into a platform project.
Make technical pain measurable
Review latency, CI time, failure rate, or support toil.
Share ownership
Coach others to own experiments.
Protect capacity
Advocate explicit improvement work.
Close the loop
Bring result back and record decision.
42. Worked Example: Review Latency Experiment
Insight
PRs wait too long.
Hypothesis
Smaller PRs and reviewer rotation will reduce wait.
Experiment
For two Sprints:
- one coherent change per PR;
- daily reviewer rotation;
- first response expectation within one working day.
Baseline
Median first review: 2.6 days.
Success signal
Median below 1 day without increased rework.
Decision
Adopt rotation; adapt PR guidance.
43. Worked Example: Refinement Quality Experiment
Insight
Acceptance criteria change mid-Sprint.
Hypothesis
Three Amigos on high-risk items will reduce rework.
Experiment
Use example mapping for top three candidate stories.
Measure
- number of mid-Sprint clarification changes;
- defect/rework;
- team feedback.
Result
If effective, add to working agreement for high-risk items only.
44. Worked Example: Flaky Test Experiment
Insight
CI reruns normalized.
Hypothesis
Visible ownership and failure budget will reduce flakiness.
Experiment
- tag flaky test;
- assign owner;
- publish count;
- fix within one Sprint;
- prevent indefinite quarantine.
Measure
- rerun frequency;
- flaky test count;
- pipeline trust feedback.
45. Worked Example: Remote Handoff
Insight
Blockers wait overnight.
Hypothesis
Structured end-of-day handoff will reduce latency.
Template
Current state:
Evidence:
Blocker:
Decision needed:
Suggested next step:
Owner:
Measure
- blocker response time;
- repeated clarification;
- and team feedback.

47. Action-Tracking Table
| Action | Owner | Baseline | Success Signal | Review Date | Status |
|---|---|---|---|---|---|
| Reviewer rotation | A | 2.6-day wait | <1 day median | Sprint 26 retro | Running |
| WIP limit | B | 9 active items | <=5 active | Sprint 26 retro | Planned |
48. Retrospective Close
Close with:
- selected action;
- owner;
- review date;
- and confidence.
Optional:
- appreciation;
- safety check;
- and facilitation feedback.
49. Process Smells
- actions not reviewed;
- same action re-created;
- owner is always Scrum Master;
- all actions require management;
- metrics absent;
- no actions adopted or abandoned;
- and improvement backlog grows indefinitely.
50. Internal Verification Checklist
Tracking
- Where are retro actions stored?
- Are they visible in Sprint work?
- Who owns updates?
- Are prior actions reviewed first?
Measurement
- What flow and quality data exist?
- Is baseline captured?
- Are qualitative signals documented?
- Are metrics used safely?
Capacity
- Is improvement work planned?
- Is there explicit capacity?
- Can team stop low-value actions?
- Does leadership support improvement?
Escalation
- How are organizational impediments raised?
- Who sponsors?
- What evidence is expected?
- Is decision latency visible?
Working agreement
- How are successful experiments institutionalized?
- Is agreement versioned?
- When is it reviewed?
- Are obsolete policies removed?
51. Practical Exercises
Exercise 1 — Rewrite actions
Convert five vague actions into measurable experiments.
Exercise 2 — Experiment canvas
Create a full canvas for one recurring bottleneck.
Exercise 3 — Baseline
Choose one metric and establish current baseline.
Exercise 4 — Follow-through audit
Review last ten retro actions and classify:
- completed;
- abandoned;
- forgotten;
- blocked;
- or repeated.
Exercise 5 — Working agreement update
Take one successful experiment and write the resulting policy.
52. Part Completion Checklist
You are done if you can:
- turn insight into hypothesis;
- design a small reversible experiment;
- assign clear ownership;
- capture baseline and success signal;
- review results;
- adopt, adapt, abandon, or extend;
- and integrate learning into working agreements or backlog.
53. Key Takeaways
- Insight without follow-through has no value.
- Experiments are stronger than vague actions.
- One or two actions are usually enough.
- Every action needs an owner.
- Baseline and success signal matter.
- Improvement work needs capacity.
- Metrics must describe systems, not judge individuals.
- Successful experiments should become durable policy or automation.
- Senior engineers should choose leverage, not complexity.
- Internal action-tracking practice must be verified.
