Message 1DevOps is Culture not Tools!


Message 2DevOps is Automation!


Tools are a Cultural Artifact


The DevOps Compact


DevOps Tools'We over the Me'


Impacts Culture (and Tools)• Organizational Structure

• Globalization


Organizational Structures• mechanistic - predictable work

• organic - unpredictable work


Mechanistic• formalized work

• centralized

• slow responding to unexpected


Organic• flexible, adaptable

• expertise, knowledge versus authority of position

• exchange of information vs direction


Differentiation - Integration Theory

• plastics - high environmental uncertainty, high competition, short product life-cycle

• containers - low environmental uncertainty, slow steady growth

• foods (somewhere in the middle)

Lawrence and Lorsche (1967)


Differentiation• task segmentation

• interpersonal orientation

• goal orientation

• timeframe


Integration• quality of collaboration needed to overcome differentiation

and achieve unity of effort


Organizational Structure• Task Structure

• Coordination

• Supervision


Interdependence• pooled

• sequential

• reciprocal

James Thompson (1967)"Organizations in Action"


Coordination• pooled - standardization in rules and processes

• sequential - adaptive planning and scheduling

• reciprocal - information sharing, and mutual evolution


Globalization


Tools Impact• Individuals

• Organizational structure


Individuals• Behaviors

• Transparency

• Control

• Empathy

• Thinking

• Automation


SVN to git


Games - Tools to Encourage Behaviors

• teach separation of identity from role playing

• empathy that every role has a part to play

• the task 'now' vs the goal

• making mistakes and resolving them

• ...


Frame Choices


Sticky notes• single vs multiple color

• sizes


Innovation• brand new

• use something for a new purpose

• combine things


MisperceptionYou're doing it wrong.


• PagerDuty to monitor glucose levels.

• Smart phones facilitating health monitoring of Parkinson's progression.


What different ways can available tools be used to improve world?


Cognition• 1977 House Committee on Science and Technology,

automation major safety concern

• Earl Wiener, human-factors and automation research in aviation


Critical thinking skills atrophy

• tracking position without the use of a map display

• deciding 'what next'

• recognizing instrument system failures

Casner and SchoolerHuman Factors


Hidden risks in removing humans out of the loop.


Humans aren't backups for machines.


Automation• education

• simplification of complexity

• documentation

Reduction of energy use without increasing potential harm.


Organization Structure• Organic

• Decentralized

• Minimize risk, encourage autonomy


Tools reflect our current state, and influence our direction.


Tool Selection


Challenges• analysis paralysis

• easy to prove 'success'

• information overload


MisperceptionBest Practice


Personal Attacks


Infrastructure Patterns• Lightning Code

• Currated Garden


What different patterns emerge from our tool implementation and

use?


Tools evolve and it's ok to change.


Identify Fragility• Single point of knowledge

• Old technology/work-arounds/Shadow IT

• Lack of knowledge


Single Point of Knowledge• The SPOF engineer


Old Technology


Work-Arounds• Technical Debt


Shadow IT


Lack of Knowledge• not knowing what we don't know

• not planning


Less than Quality Solution• adopting "easy" or "one stop DevOps solutions"


Quality Solution• Inter-organizational interactions

• DevOpsDays, Velocity conferences

• Training, meetups

• Adhoc open spaces - CoffeeOps

• Hiring for Diversity


Balance• fit the needs of people/groups

• consistency across organization

• freedom of choice


Deliberate Choices with Active Participants• Destination and the Journey

• Single Points of Authority


Organizational SPA• Bug tracking

• Task visualization

• Logging infrastructure


Group SPA• Local Development environment (LDE)

• Workflow


Chef LDECenturyLink Cloud


Trello Workflow


Individual SPA• Editor

• Desk

• Work Environment


ReviewTools for Effective Change

• Emphasize 'We over the Me'

• Tools reflect our current state, and influence our direction.

• Tools evolve, and change is ok.

• Choose tools deliberatey with active participation.


Tools are critical to DevOps in how they are chosen, implemented, and used by humans.
