The
Principles
of Flow
The First Way fast and smooth flow
of work
from Dev to Ops
to deliver value to
customers quickly

The
Principles
of Flow
The First Way  Limit WIP
 Reduce Batch Sizes
 Reduce the number
of handoffs
 Continually elevate
constraints

Build a fast, reliable pyramid of tests
Test first; automate always
Integrate non-functional
requirements into tests
Pull the andon cord!

Standardize
Environments
Create a single repo of truth
On-demand creation of envs
Rebuild, not repair
Done = running in prod-like env

The
Principles
of
Feedback
The Second Way
fast feedback
from right to left
create safety &
resiliency in
complex systems

17.

Use telemetry Use peer
reviews and
inspections
Get feedback
from
deployments
The Second Way: The Principles of Feedback
fast and continuous feedback from Operations to Development

Use telemetry Use peer

Get feedback
from
deployments
The Second Way: The Principles of Feedback
fast and continuous feedback from Operations to Development
• See problems as they occur
• Log useful metrics
• Overlay other relevant information e.g. releases
• Analyze: Means, SDs

Use telemetry Use peer

inspections
Get feedback
from
deployments
The Second Way: The Principles of Feedback
fast and continuous feedback from Operations to Development
For deployment and releases:
• Actively monitoring feature metrics
• Have devs initially self-manage prod releases
• Then dev and ops should share pager duty

Use telemetry Use peer
reviews and
inspections
Get feedback
from
deployments
The Second Way: The Principles of Feedback
fast and continuous feedback from Operations to Development
• Avoid formal approval processes, manual testing
• Get feedback closer to the source
• Favor peer reviews and inspections
e.g,. GitHub PR, pair programming
• Fearlessly cut bureaucratic processes

Continual
Learning &
Experimentation
The Third Way
high-performing
teams require
and actively
promote
learning
If you're not
improving, you
are getting
worse!

22.
Enable organizational learning

Errors Happen! Blameless
post-mortems
local -> global
learnings
How does your org
respond?
Pathological,
bureaucratic or
generative?
- blame
- fear
+ honesty & learning
share RCAs, code,
best practices
