47.
THE AGILE TEST

48.
INDIVIDUALS AND
INTERACTIONS OVER
PROCESSES AND TOOLS
Developers can take risks such as
upgrading PHP knowing they can get
back to a working state in seconds
instead of days. Enabling innovation
means better velocity.
[DevOps: Velocity = Revenue]

49.
WORKING SOFTWARE
OVER COMPREHENSIVE
DOCUMENTATION
The Dockerfile (code) that describes the
run time environment is what ensures
a working environment, not a huge
wiki that is chronically out of date.
[DevOps: Infrastructure as Code]

50.
CUSTOMER
COLLABORATION OVER
CONTRACT NEGOTIATION
A developer can change the function of a
service in a container and show it to a
customer (B2B) asking, "like this?”
Developers can kick out new features that can
be A/B tested on a SaaS offering (B2C)
[DevOps - Shorten Feedback Loops]

51.
RESPONDING TO
CHANGE OVER
FOLLOWING A PLAN
Black box thinking means the role of ops
changes to expressing operational measures
(security, performance, scale) in terms of
automated testing. Innovation increases
because feedback comes sooner.
[DevOps - Innovation means competitive
advantage]

52.
BUILD AND TEST AGILITY

55.
THE AGILE TEST

56.
INDIVIDUALS AND
INTERACTIONS OVER
PROCESSES AND TOOLS
At the bleeding edge, collaboration across
function becomes about producing tests
rather than processes for inhibiting
innovation. Code becomes the documentation
and collaboration happens at the engineering
level rather than the process control level.
[DevOps: Test all the things]

57.
WORKING SOFTWARE
OVER COMPREHENSIVE
DOCUMENTATION
Better modeling of the production
environment, especially in a disposable
way, deploys are seamless in all
environments
[DevOps: Continuous Delivery]

58.
CUSTOMER
COLLABORATION OVER
CONTRACT NEGOTIATION
A/B testing is a form of collaboration,
though generally an individual
customer is unaware they are a test
subject.
[DevOps - Short Feedback Loops]

59.
RESPONDING TO
CHANGE OVER
FOLLOWING A PLAN
Responding to change is the definition
of both build and quality engineering.
Docker adoption has no effect.

THE AGILE TEST

64.
INDIVIDUALS AND
INTERACTIONS OVER
PROCESSES AND TOOLS
On the bleeding edge change becomes about how to
ensure behavior of software rather than people.
Software problems are easier than people problems.
I believe the manifesto needs an update here to value
the _quality_ of interaction.
[DevOps - Reduce need for human intervention]

65.
WORKING SOFTWARE
OVER COMPREHENSIVE
DOCUMENTATION
Automated coordination between
environments means less deploy
friction for PM’s to manage.
[DevOps: Continuous Delivery]

66.
CUSTOMER
COLLABORATION OVER
CONTRACT NEGOTIATION
Use of disposable environments could
lead to PMs doing check-ins with
customers that ask, "Like this?"
[DevOps - Short Feedback Loops]

67.
RESPONDING TO
CHANGE OVER
FOLLOWING A PLAN
Micro teams move at their own pace. The
response to change is much more rapid.
There is little inter-team communication
required so the quality of intra-team
communication can be improved.
[DevOps - Increase efficiency holistically]

68.

THE AGILE TEST

72.
INDIVIDUALS AND
INTERACTIONS OVER
PROCESSES AND TOOLS
At the operational level, Docker is a
technology.
Again, I believe the manifesto needs
and update to value the _quality_ of
interaction.

73.
WORKING SOFTWARE
OVER COMPREHENSIVE
DOCUMENTATION
Containers are portable, so "works on
my machine" is not a consideration in a
Docker shop. When software gets to Ops,
it works.
Testing will need to focus on security
and performance.

74.
CUSTOMER
COLLABORATION OVER
CONTRACT NEGOTIATION
At Pantheon, for example, this is a crucial
point. Customers use the fully featured system
indefinitely for free. They purchase value
added services like performance, back up and
the like.
[DevOps - Value is in what the market will
pay for.]

75.
RESPONDING TO
CHANGE OVER
FOLLOWING A PLAN
Ops, in terms of DevOps thinking, is about eliminating
the need for reaction in the production environment.
An argument can be made that Docker allows for
automated response to change (scaling and disasters
for example)
[DevOps - Reduce need for human intervention]
