Tom Gilmore (www.linkedin.com/in/gilmoretom) is an author (A Tale of Two
Companies), Agile/DevOps Coach. Tom brings a unique background to
coaching, having started his career working in manufacturing operations
management where he worked closely with Lean Manufacturing and TQM
concepts. Tom’s educational studies have helped foster these Lean
foundational beliefs, with a BS in Purchasing, Operations and Logistics
Management and an MBA in Technology and Innovation Management.
With over 20 years of experience in Lean Manufacturing, TQM, Agile Development, DevOps, Quality Assurance, Agile Testing and
Automated Testing, he has helped coach many organizations in their change in philosophies towards Agile and DevOps in order to
become Learning Organizations. Tom has worked closely with individuals, teams and management to coach them on the intricacies of
Organizational Behavior and Development in order for the organization to create a social environment where learning can take place.
Tom’s coaching focuses on helping the organization create a cultural climate that allows individuals to improve, because as
individuals get better at what they do, teams naturally improve. And when teams improve, organizational results dramatically improve.
His experience as a Coach with Torak includes the following organizations: SkyTouch Technology, Able Engineering, Evaluate to
Win, Forever Living, Concord Servicing, First Solar, Choice Hotels International, Glynlyon, Discount Tire, Edgenuity, Really Simple by
RSP, AgWorks, Mayo Clinic, Best Western International, NantHealth, NTNBuzztime and AAA Carolinas.
About Tom Gilmore

• Mistake to attempt to define DevOps (Gives illusion that it is some step
by step program)
• DevOps is a philosophy/mindset, guided by among others, Andon
Culture, Continuous Learning and Lean
• DevOps is more likely a reaction to Agile then an extension of Agile
• DevOps should be driven by science
• DevOps is a Journey!
What is DevOps?

• Foundations
• Mindset
• Transformation
• Implementation
• Learning
• Toolchain
The DevOps Journey

• What happens when we fail to understand the Foundations?
• Dr. W. Edwards Deming
• Bernoulli’s Principle
• Conway’s Law
• Lean Manufacturing
• Agile
Foundations

Dr. W. Edwards Deming
Foundations

• Strategic reasons for DevOps
• Technical Debt
• Using Kaizen to fight waste
• SWOT Analysis
• Value Proposition Cards
• Understanding Denialism
Mindset

SWOT Analysis
Mindset

• It’s about Culture!!
• Moving from a Ticket Taking Culture
• Organizational Behavior
• Organizational Development
• Management by Objectives
• Blame Game
• Components of Change
• Breaking down silos
Transformation

• Everyone is Responsible for Quality
• Listening
• Using surveys in DevOps to Stimulate Information Sharing
• Double Loop Learning
• Tightly Coupled Code
• Murphy’s Curve
Transformation

Organizational Behavior
• Is a science that most of the DevOps culture change is actually based
on
• Toyota’s opening of manufacturing plants in the US is a lesson in the
use of Organizational Behavior
• OB explains “fear” inside an organization and how to combat it
• Explains why Dojo’s worked at Target, but may not work at other
companies (created social environment with necessary components to
foster learning)
• Details how to overcome the Blame Game using Superordinate Goals
Transformation

Organizational Behavior
• Describes how DevOps can be used to overcome stress in the
organization
• Breaks down how to overcome the Barriers to Communication that can
derail a DevOps effort
• Defines the organizational communications roles that need to be filled
to successfully champion DevOps
• Puts a spotlight on why DevOps leaders need to understand the
difference between the informal organization culture and the formal
organization culture to succeed (Hint – need to control the grapevine)
• Are you providing Cross Cultural Communication training? Should be,
look around your workplace
Transformation

Organizational Development
• Is a subset of Organizational Behavior and a very important one!
• Did you know DevOps is actually an Organizational Development
“Change Agent”?
• OD explains the big picture of organizational change and the sources
of resistance the Change Agent will meet and how to overcome them
• Introduces important tools such as Forcefield analysis
• Explains the elements that make up an organizational culture
• If you don’t understand OB and OD, then you will have to rely on luck
to be successful in DevOps
Transformation

Management by Objectives (MBO)
• The vast majority of DevOps leaders and practitioners have missed
one of Dr. Deming’s most important contributions
• Deming was emphatically clear, Management by Objectives was a bad
idea
• Deming called MBO “an attempt to manage without knowledge of what
to do”.
• Peter Drucker who created MBO, also came around to the same point
of view as Deming 15 years later
• MBO is ingrained in the culture of many organizations even today
(especially American organizations)
• The MBO process works counter to what we are attempting with
DevOps
Transformation

Blame Game and Components of Change
• Many in the industry are advising that to overcome the Blame Game
you just need to change the incentives
• Changing incentives will bring about change, but it may not bring the
change you were hoping for
• Change is multi faceted with many components, only if all the
components are in place will you get the desired change
Transformation

• Management’s role in DevOps
• Organizational Structures
• Value Stream Mapping
• Eliyahu M. Goldratt – Theory of Constraints (5 focusing steps)
• Flipping the Testing Pyramid
• Hidden Constraints
• Tackling Training
• Dojo’s and Centers of Excellence
Implementation

• Choosing an Agile Methodology
• Evangelize, Evangelize and keep doing it
Implementation

Applying Lean Tools to DevOps
• Tools such as Theory of Constraints and Value Stream Mapping can
be used in DevOps, but understand they need a little tweaking to be
used
• In manufacturing, the Theory of Constraints and Value Stream
Mapping are used with widgets we can touch, feel, see and measure,
in DevOps we have black boxes
• When using the Theory of Constraints in manufacturing we have to
lookout for “hidden constraints”, they also exist in DevOps – do you
know how to find them?
• Don’t make the same mistake as some in Agile have made with Little’s
Law, some Lean tools/concepts simply aren’t applicable
Implementation

• DevOps = Continuous Learning Organization
• Andon Culture
• Striving for Green
Learning

Andon Culture
• Understand what Andon (Andon Cord) is
• More importantly, discover the original reason why Toyota created the
Andon concept
• Learn how to apply Andon to DevOps and how other organizations
have applied it
• Research how the Andon Culture has shaped Amazon
Learning

• Code
• Build
• Test
• Package
• Release
• Configure
• Monitor
• Safeguard
Toolchain

• DevOps SCM Strategy
• Specification by Example
• Unit Testing – This is a cultural issue not a tool issue
• Agile Architecture
• Rev up Quality with code reviews
Code

• Define CI and CD
• Continuous Integration
• Versioning
• Quality Gates
• Artifact Repository
Build

• Why TDD
• True automated testing – Remember those Hidden Constraints?
• Security and Compliance
• Testing components
• Testing tools
• Probably the biggest Achilles heel to DevOps efforts
Test

• Change Management
• Pipeline swarming
• Remember, in DevOps the Change Management process changes
• The Pipeline is the Change Management process
Package

• Release Strategy
• DevOps release strategies have some strategic advantages
Release

• DevOps infrastructure
• It’s all about Feedback Loops
• DevOps Orchestration versus Automation
• Be familiar with the concepts of Evolutionary Development/Architecture
and the Strangulation Method
Configure

• Telemetry and Monitoring
• DevOps Metrics
• A/B Testing – Strategic advantage if done correctly
• Reporting
Monitor

• Simian Army
• Maximize Post Mortems
• False Prophets
Safeguard
