Giới Thiệu: Why Data Teams Need Rituals

Scenario thường gặp (Data Team không có structure):

Monday morning:
- Engineer 1: Working on pipeline X (stakeholder doesn't know)
- Engineer 2: Blocked on data access (nobody knows)
- Analyst: Working on ad-hoc request from Friday (forgot original context)

Friday:
- Manager: "What did team accomplish this week?"
- Team: "Uh... stuff?"
- No visibility, no accountability, chaos

Vấn đề:

• ❌ No coordination (duplicated work, blocking each other)
• ❌ No visibility (stakeholders don't know progress)
• ❌ No learning (repeat same mistakes)

Rituals giải quyết:

• ✅ Daily standup → Coordination, unblock
• ✅ Sprint planning → Prioritize, commit
• ✅ Sprint review → Demo work, get feedback
• ✅ Retrospective → Continuous improvement
• ✅ Documentation → Knowledge sharing

High-performing data teams have strong rituals.

Agile for Data Teams: Adaptations

Challenge: Data Work is Different

Software engineering:

• Predictable: "Build login feature" → 2 weeks (can estimate)
• Binary: Feature works or doesn't
• Iterative: Ship v1, then v2, v3

Data work:

• Exploratory: "Why did revenue drop?" → ??? (unknown unknowns)
• Continuous: Data quality, pipeline maintenance (never "done")
• Ad-hoc heavy: 50% planned work, 50% urgent requests

Agile Adaptations for Data

1. Timeboxing Exploratory Work

Instead of:

Task: "Analyze customer churn"
Estimate: ??? (could be 1 day or 1 month)

Timebox:

Task: "Churn analysis (timeboxed to 2 days)"
Day 1: Explore data, identify patterns
Day 2: Document findings, recommend next steps

If need more time → Create follow-up task

Benefit: Prevents analysis paralysis, forces prioritization.

2. Hypothesis-Driven Analysis

Instead of:

Task: "Analyze sales data"
→ Too broad, endless

Hypothesis:

Task: "Test hypothesis: Discount campaigns don't improve LTV"
Approach:
1. Cohort analysis: Discounted vs full-price customers
2. Measure 6-month LTV
3. Statistical test (t-test)
4. Recommend: Continue discounts or not

Estimated: 3 days

Benefit: Clear scope, measurable outcome.

3. Kanban + Scrum Hybrid

Pure Scrum: Fixed 2-week sprints, commit to backlog

• Problem for data: Ad-hoc requests disrupt sprint

Pure Kanban: Continuous flow, no sprints

• Problem: No forcing function to demo work

Hybrid (Best for data teams):

Sprint = 2 weeks
Capacity allocation:
- 60% planned work (from backlog)
- 40% ad-hoc capacity (buffer for urgent requests)

Still have sprint planning, review, retro
But flexible to handle ad-hoc without breaking sprint

Key Rituals

1. Daily Standup (15 Minutes)

Format: Team stands (or video call), quick updates.

3 Questions:

1. What I did yesterday
2. What I'll do today
3. Any blockers

Example:

Engineer 1:
- Yesterday: Finished Airflow DAG for customer events
- Today: Deploy to prod, monitor
- Blockers: Need approval from DevOps for IAM role

Engineer 2:
- Yesterday: Investigated slow BigQuery query
- Today: Implement partition pruning, test
- Blockers: None

Analyst:
- Yesterday: Started churn analysis
- Today: Finish cohort segmentation
- Blockers: Need clarification from Product on definition of "active user"

Rules:

• ✅ Keep it short: 15 minutes MAX (for 5-person team = 3 min/person)
• ✅ Standups are for coordination, not problem-solving
  • If deep discussion needed: "Let's take this offline" (after standup)
• ✅ Same time, every day (e.g., 9:30 AM)
• ✅ Everyone attends (unless OOO)

Common mistakes:

• ❌ Too long (30-45 min) → People zone out
• ❌ Manager turns it into status report → Should be peer-to-peer
• ❌ Problem-solving during standup → Wastes everyone's time

Remote team adaptation:

• Async standup: Post updates in Slack channel before 10 AM
• Synchronous huddle: 10 AM video call (optional, for blockers)

2. Sprint Planning (2 Hours, Bi-Weekly)

Goal: Prioritize work, commit to sprint goals.

Agenda:

Part 1: Review Backlog (30 min)

• Product Manager / Stakeholders present priorities
• Data team asks clarifying questions

Part 2: Estimation (45 min)

• Team estimates effort (t-shirt sizes or story points)
• T-shirt sizes: S (1 day), M (2-3 days), L (1 week), XL (2 weeks)
• Discuss complexity, unknowns

Example:

Task: "Build pipeline for new payment data"
Engineer 1: "This is M - source is new API, need to learn it, but transformation straightforward"
Engineer 2: "Agree, M"
Estimate: M (2-3 days)

Part 3: Commit to Sprint (45 min)

• Calculate team capacity:

  Team: 5 people
  Sprint: 2 weeks = 10 days/person = 50 person-days total
  Minus:
  - Holidays: 2 days
  - Meetings: 5 days (10%)
  - Ad-hoc buffer: 15 days (30%)
  
  Available: 28 person-days
  
  Can commit to: 28 days of S/M/L tasks
  

• Pull top-priority tasks from backlog until capacity full

• Sprint goal: "Migrate 20 critical pipelines to Prefect"

Outcome: Clear sprint backlog, team aligned.

3. Sprint Review / Demo (1 Hour)

Goal: Show completed work, get feedback from stakeholders.

Attendees: Data team + stakeholders (Product, Marketing, Execs)

Format: Live demos (not slides!)

Example:

Analyst presents:
"This sprint, I analyzed churn for our premium tier.

[Shares Looker dashboard]

Key findings:
1. Churn rate: 5% monthly (higher than standard tier at 3%)
2. Main reason: Price sensitivity (survey data)
3. Hypothesis: Discount for 3-month commitment → Reduce churn

Recommendation: Run A/B test

Questions?"

Stakeholders ask questions, provide feedback
PM: "Great, let's prioritize A/B test next sprint"

Benefits:

• ✅ Visibility (stakeholders see progress)
• ✅ Feedback (catch misunderstandings early)
• ✅ Celebration (motivates team)

Anti-pattern:

• ❌ No demo (just status report) → Boring
• ❌ Only slides (not actual work) → Not convincing

4. Retrospective (1 Hour)

Goal: Reflect on sprint, identify improvements.

Format: Blameless discussion (no finger-pointing).

3 Questions:

1. What went well? (keep doing)
2. What didn't go well? (stop doing)
3. What can we improve? (action items)

Example:

What went well:
- ✅ Migration to Prefect smooth
- ✅ Good collaboration with ML team
- ✅ All critical pipelines stable

What didn't go well:
- ❌ 3 ad-hoc requests took 15 hours (30% of sprint)
- ❌ BigQuery costs spiked (didn't notice until bill)
- ❌ Documentation lacking for new pipelines

Action items:
1. Create ad-hoc request triage process (only accept if urgent + high impact)
2. Setup BigQuery budget alert ($500/day)
3. Mandate documentation checklist for all new pipelines
   - Owner: Engineer 1
   - Due: Next sprint

Retro formats (rotate to keep fresh):

• Start/Stop/Continue
• Glad/Sad/Mad
• 4Ls: Liked, Learned, Lacked, Longed for
• Sailboat: Wind (helping), Anchor (blocking), Rocks (risks)

Psychological safety: Critical for honest retros.

• No blame ("Pipeline failed" vs "You broke pipeline")
• Manager participates as peer (not judge)
• Rotate facilitator

5. Backlog Grooming (1 Hour, Weekly)

Goal: Refine user stories, add details, prioritize.

Activities:

1. Refine vague requests:

Before:
"Need marketing data"

After grooming:
Title: "Build dashboard for email campaign performance"
Description:
- Metrics: Open rate, click rate, conversions, revenue
- Granularity: Daily, by campaign
- Tool: Looker
- Stakeholder: Marketing Manager
Acceptance criteria:
- [ ] Dashboard live in Looker
- [ ] Marketing team trained
- [ ] Documentation written
Estimate: M (3 days)

2. Break down large tasks:

Epic: "Migrate to Snowflake"
↓ Break into stories:
- Setup Snowflake account
- Migrate 10 critical tables
- Migrate dbt models
- Migrate BI dashboards
- Cutover & validation
- Decommission old warehouse

3. Prioritize:

• Use framework: Impact vs Effort matrix

High Impact, Low Effort → Do now
High Impact, High Effort → Plan carefully
Low Impact, Low Effort → Nice to have
Low Impact, High Effort → Don't do

Outcome: Backlog ready for next sprint planning.

Additional Rituals

6. Office Hours (2 Hours, Weekly)

Goal: Open time for business users to ask data questions.

Format:

Every Friday 2-4 PM
Zoom room open
Anyone can join, ask questions
Topics:
- SQL help
- Dashboard debugging
- Metric definitions
- Data access requests

Benefits:

• ✅ Reduces ad-hoc Slack interruptions (batch questions)
• ✅ Just-in-time learning
• ✅ Builds relationship with stakeholders

Example questions:

• "How do I calculate churn rate?"
• "Why is my dashboard blank?"
• "Can I get access to customer data?"

7. Show & Tell (1 Hour, Monthly)

Goal: Team members share learnings.

Format: Casual presentation (15-20 min talk + Q&A)

Topics:

• New tool tried: "I tested Great Expectations for data quality"
• Technique learned: "Incremental models in dbt"
• Analysis insights: "How I identified $50K revenue leak"
• Conference recap: "Key takeaways from DataEngConf"

Benefits:

• ✅ Knowledge sharing
• ✅ Presentation practice
• ✅ Cross-pollination (analysts learn from engineers, vice versa)

8. Documentation Rituals

Problem: Documentation always outdated or nonexistent.

Solution: Make documentation mandatory part of "Done".

Definition of Done (checklist):

Task: "Build new pipeline"

Done when:
- [ ] Code written & tested
- [ ] Deployed to prod
- [ ] Monitoring setup (alerts)
- [ ] Runbook created (how to troubleshoot)
- [ ] dbt docs updated
- [ ] Team notified (Slack #data-team)

Documentation types:

1. Runbooks:

# Runbook: Customer Events Pipeline

## Overview
Ingests customer events from Kafka → Snowflake

## Schedule
Runs every 5 minutes

## Monitoring
- Datadog: "customer_events_pipeline" dashboard
- Alert: If lag > 30 min

## Troubleshooting
### Pipeline failing
1. Check Kafka lag: ...
2. Check Snowflake connection: ...
3. Escalate to: @engineer-on-call

### Data looks wrong
1. Check source data quality: ...
2. Verify transformations: ...

2. ADRs (Architecture Decision Records):

# ADR: Migrate from Airflow to Prefect

## Status: Accepted

## Context
Airflow maintenance overhead high, observability poor

## Decision
Migrate to Prefect

## Consequences
- Pros: Better UI, cloud-native, less ops
- Cons: Team needs retraining, migration effort
- Alternatives considered: Dagster (too complex), keep Airflow (too painful)

3. Weekly Snippets:

Each engineer posts weekly update in Slack #data-snippets

Example:
Week of Aug 19:
- ✅ Completed: Churn analysis
- 🚧 In Progress: Email pipeline migration
- 📚 Learned: dbt snapshots for SCD Type 2
- 🎯 Next week: Dashboard for exec team

Communication Tools

1. Slack Channels

Structure:

#data-team (internal team chat)
#data-requests (stakeholders submit requests)
#data-office-hours (Q&A)
#data-incidents (production issues)
#data-wins (celebrate successes)

Best practices:

• ✅ Use threads (keep conversations organized)
• ✅ Tag relevant people (@alice for SQL questions)
• ✅ React with emojis (✅ = acknowledged, 🚀 = shipped)

2. Jira / Linear (Task Management)

Workflow:

Backlog → To Do → In Progress → Review → Done

Columns:
- Backlog: All requests
- To Do: Sprint committed
- In Progress: Currently working (limit: 2/person)
- Review: Code review / QA
- Done: Shipped

Labels:

• bug, feature, tech-debt, ad-hoc
• P0 (urgent), P1 (high), P2 (medium), P3 (low)

3. Confluence / Notion (Documentation)

Structure:

Meeting Hygiene

Best Practices

1. Always have agenda:

Meeting: Sprint Planning
Date: Aug 26, 2025
Agenda:
1. Review last sprint (10 min)
2. Backlog priorities from PM (20 min)
3. Estimation (40 min)
4. Sprint commitment (30 min)
5. Parking lot (20 min)

Total: 2 hours

2. Take notes:

• Designate note-taker (rotate)
• Action items: Who, What, When
• Share notes in Slack after meeting

3. Start/end on time:

• Respect people's calendars
• If need more time → Schedule follow-up

4. No laptop rule (for some meetings):

• Retros, brainstorming: Full attention
• Planning: OK to have laptop (need to estimate)

Remote Team Considerations

Challenges

Timezone differences:

Team:
- Engineer 1: HCMC (UTC+7)
- Engineer 2: Hanoi (UTC+7)
- Engineer 3: US West Coast (UTC-8) → 15 hours behind

→ Finding meeting time hard

Solution: Async-first culture

1. Async Standups:

Instead of daily 9 AM standup:

Post updates in Slack #data-standup by 10 AM local time

Template:
Yesterday: Finished X
Today: Working on Y
Blockers: Z

Engineer 3 (US) posts before sleeping, team reads next morning

2. Recorded Demos:

Sprint review:
- Record demo video (Loom)
- Post in Slack with written summary
- Stakeholders watch async, comment

Follow-up: 30-min sync Q&A (if needed)

3. Written RFCs:

Instead of architecture discussion meeting:

Write RFC (Request for Comments) doc
Team reviews, comments inline (Google Docs)
Discuss async in comments
Final decision: Async vote or short sync meeting

Zoom Fatigue

Problem: 5+ hours of video calls/day → Exhausting

Solutions:

• No-meeting Wednesdays: Deep work day
• 25-min meetings (not 30): 5-min break between
• Walking 1-on-1s: Voice call while walking (no video)
• Async default: Meeting only if truly necessary

Case Study: High-Performing Data Team

Background

Company: SaaS startup, 200 employees Data team: 6 people (3 engineers, 2 analysts, 1 manager)

Before rituals (6 months ago):

• Chaos: No coordination
• Backlog: 50+ untracked requests
• Delivery: Unpredictable
• Morale: Low (team felt firefighting constantly)

Implemented Rituals (3 Months Ago)

Week 1: Setup Jira, migrate all requests to backlog

Week 2-4: Started core rituals

• Daily standup (9:30 AM, 15 min)
• Bi-weekly sprint planning (Monday, 2h)
• Bi-weekly retro (Friday, 1h)

Month 2: Added supporting rituals

• Weekly backlog grooming (Wednesday, 1h)
• Office hours (Friday 2-4 PM)

Month 3: Refined processes

• Created Definition of Done checklist
• Runbook template
• Async standup option for remote days

Results (After 3 Months)

Delivery:

• Sprint commitment: 90% completion rate (vs 50% before)
• Lead time: 5 days average (vs 15 days before)
• Stakeholder satisfaction: 4.2/5 (vs 2.8/5)

Team:

• Morale: Much improved (retros show positive sentiment)
• Coordination: Zero blocking issues (spotted & resolved in standups)
• Learning: 3 process improvements implemented from retros

Visibility:

• Stakeholders know what team is working on
• Clear backlog (50 requests → Prioritized into sprints)

Manager: "Rituals transformed our team from reactive firefighting to proactive delivery."

Common Pitfalls

1. Rituals Become Meetings

Symptom: Team dreads standups, retros feel like waste of time.

Cause: Lost focus, no action items, too long.

Fix:

• Timebox strictly (15 min standup, not 30)
• Parking lot for deep discussions (don't derail)
• Retro action items → Jira tickets (actually do them)

2. Cargo Cult Agile

Symptom: Following rituals mechanically without understanding why.

Example:

Team: "We do standups because Scrum book says so"
Manager: "Why?"
Team: "Uh... not sure"

→ Standup becomes status report to manager, no value

Fix: Understand purpose of each ritual, adapt to your needs.

3. No Flexibility

Symptom: Strict Scrum → Can't handle ad-hoc requests → Stakeholders frustrated.

Fix: Hybrid model (60% planned, 40% ad-hoc buffer).

4. Documentation Neglected

Symptom: Rituals running, but knowledge lost when people leave.

Fix: Make documentation part of Definition of Done.

Kết Luận
