Five habits we’ve learned so far

Listen to our customers
Customer Focused

Collect data
broadly (but carefully)

But measure what’s important (KPI’s)
Customer Focused
• Original estimate
• Completed hours
• Lines of Code
• Team capacity
• Team burndown
• Team velocity
• # of bugs found
Things we don’t watch
• Acquisition
• Engagement
• Satisfaction
• Churn
• Feature Usage
Usage
• Time to Detect
• Time to Communicate
• Time to Mitigate
• Customer Impact
• Incident Prevention Items
• Aging Live Site Problems
• SLA per Customer
• Customer Support Metrics
Live Site Health
• Time to Build
• Time to Self Test
• Time to Deploy
• Time to Learn
Process Velocity

Be Transparent
Production First Mindset

Alerting is the key to fast detection
Before
• Redundant alerts for same the issue
• Needed to set right thresholds and
tune often
• Stateless alerts contributed to
further noise
After
• Every alert must be actionable and
represent a real issue with the
system.
• Alerts should create a sense of
urgency – false alerts dilutes that
• Use alerts to auto-dial the DRIs.

Security Mindset
 Double blind test
 Full disclosure at or near end
vs.
 Share tactics & lessons learned
 Continued evolution
Assume Breach - Use War Games to the learn attacks and practice response

Agile at Scale with Aligned Autonomy
Team Autonomy & Enterprise Alignment

Roles
Program Management Engineering

Yes, there are other roles…
Program Management Engineering Service DeliveryUX UE
Service Delivery is integrated
directly into our organization.

Teams
Program Management is responsible for:
WHAT we’re building, and
WHY we’re building it
Engineering is responsible for
HOW we’re building it, and that
we’re building it with QUALITY

Teams
 Physical team rooms
 Cross discipline
 10-12 people
 Self managing
 Clear charter and goals
 Intact for 12-18 months
 Own features in production
 Own deployment of features

Instead of Horizontal…

API
Data

We strive for Vertical

Employee choice, not
manager driven
Typically <20%
change, but 100% get
to make a choice
Cross-pollinate talent
and micro-culture

Before – Debt Cycle
Shift Left Quality

• Tests that anyone can run anywhere (inc production)
• Shifted to unit tests from automated functional tests
• Core tests run before pull request
• Fast and 100% reliable build and test is critical
• Rolling tests run after commit

Architecture Modernization

•
• If you are starting out today and cloud native, consider
PaaS, Service Fabric + Azure Functions
• We need to ship same code to on-prem & cloud

Our DevOps Transformation – the story so far
After
• 3-week sprints
• Vertical teams
• Team rooms
• Continual Planning & Learning
• PM & Engineering
• Continual customer engagement
• Everyone in master
• 8-12 person teams
• Publicly shared roadmap
• Zero debt
• Mockups in PPT
• Inner source
• Flattened organization hierarchy
• User satisfaction determines success
• Features shipped every sprint
Before
• 4-6 month milestones
• Horizontal teams
• Personal offices
• Long planning cycles
• PM, Dev, Test
• Yearly customer engagement
• Feature branches
• 20+ person teams
• Secret roadmap
• Bug debt
• 100 page spec documents
• Private repositories
• Deep organizational hierarchy
• Success is a measure of install numbers
• Features shipped once a year

Lastly the DevOps Ranger Transformation
DevOps even works for a part-time open source community 
After
• 0.25 program managers
• Automated CI
• Automated CD
• 3-5 sprints cadence
• 3-week sprints
• Proactive telemetry
• Minutes to days to resolve issues
• Minutes to build
• Minutes to release
Before
• 2 program managers
• Manual and error prone builds
• Manual and error probe releases
• 6-12 sprint cadence
• 1 month sprints
• Issues detected by users
• Days to weeks to resolve issues
• Hours to build
• Days to release
