Agenda
• Value of tools within devops• Interdependence of Organizational Structures, Globalization and Tools• Effective Selection of Tools
Conflicting Messages
DevOps is Culture not Tools!DevOps is Automation!
Tools are a Cultural Artifact
Tools are a Cultural Artifact
“We become what we behold. We shape our tools and then our tools shape us”
Father John Culkin
DevOps Tools stress “We over the Me”
The DevOps Compact
Impacts Culture (and Tools)
•Organizational Structure•Globalization
Organizational Structure
Defines how work is divided, people assigned, coordination of teams.
Mechanistic – Predictable work
• Formalized work• Specialized work• Centralized• Chain of Command• Slow responding to unexpected
Organic – Unpredictable work
• 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)
Task Structure - Layers of Interdependence
• pooled• sequential• reciprocal
Organizations in Action, James Thompson (1967)
Globalization
Tools Impact
• Individuals•Organizational structure
Individuals
• Behaviors Transparency Control Empathy
• Thinking
SVN to git
Manual Configuration to Infrastructure as Code
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•Combining existing things into something new
Misperception
You’re doing it wrong
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
Human FactorsCasner and Schooler
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.
Tools reflect our current state, and influence our direction.
Tool Selection
Challenges
• analysis paralysis• easy to prove 'success’• information overload
Misperception
Best Practice
Personal Attacks
Infrastructure Patterns
• Lightning Code• Curated 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
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

Review Tools for Effective Change
• Value of tools within devopsEmphasizing the ‘We over the Me’
Review Tools for Effective Change
• Interdependence of Organizational Structures, Globalization and Tools
Tools reflect our current state and influence our direction.
Review Tools for Effective Change
• Effective Selection of Tools1. Learn about the problem space.2. Tools evolve, and change is ok.3. Choose tools deliberately with active participation at the
appropriate level of authority.
Tools are critical to DevOps in how they are chosen, implemented,
and used by humans.
