@conorfi
My Journey with the MT Principles
1. Each principle explained
2. A real world example
3. A suggestion for you to try

@conorfi
1. Business First
“Our priority is improving the business.”
“A good test mind applied to a feature
team is a value-add, not a cost.”

@conorfi
Feature Toggles
“Feature Toggles/Flags are a powerful
technique, allowing teams to modify system
behavior without changing code”
Martin Fowler

@conorfi
16 Splits - Status Unknown

@conorfi
16 Splits - Status Known

@conorfi
16 Splits - Status Improving

@conorfi
Suggestion
Ask how can we improve the business?

@conorfi
2. Accelerate the Team
“We accelerate the team, and use
models like Lean Thinking and the
Theory of Constraints to help identify,
prioritize and mitigate bottlenecks from
the system”

@conorfi
Acceptance Queue Bottleneck

@conorfi
Acceptance Queue Unblocked

@conorfi
Suggestion
Ask what things speed up or slow
down the team?
How can your testers help you release
higher quality software faster?

@conorfi
3. Always Learn and Improve
“We are a force for continuous
improvement, helping the team adapt
and optimize in order to succeed,
rather than providing a safety net to
catch failures.”

@conorfi
Learning and Improving
Improved Retrospectives
Introduction of Post-mortems

@conorfi
Suggestion
What key Improvement could your
team make right now?
What or who would it help?
How will you know if it has improved
something?

@conorfi
4. Lead a Quality Culture
“We care deeply about the quality
culture of our team, and we coach,
lead, and nurture the team towards a
more mature quality culture.”

@conorfi
Quality Definition
“Quality is value to some person, at
some time, who matters”
Jerry Weinberg(extended by Michael Bolton)

@conorfi
Quality Consists of
Dan Ashby

@conorfi
Quality Culture Definition
“Shared Mindset that delivering high
quality to our customers is our top
priority, and that all our practices
support this effort”
Alan Page

@conorfi
Quality Culture Transition Guide
A framework that teams can use to drive discussion
Not a Capability Maturity Model
Focus is more on areas for improvement than levels
9 Capabilities and 4 levels

@conorfi
Suggestion
Could you try the Quality Culture
Transition Guide with your team?

@conorfi
5. The Customer is King
“We believe that the customer is the
only one capable to judge and
evaluate the quality of our product”

@conorfi
Controversial?
“The Customer is the only one that knows
whether or not the product is solving their
problem.”
“Quality is customer happiness. (not leads
to… is)”
Brent Jensen https://testastic.wordpress.com/

@conorfi
Talking to Customers
1. Qualitative
2. Quantitative (Next Principle)

@conorfi
Suggestion
Is there a customer your team should
be talking to right now?

@conorfi
6. Data Trumps intuition
“We use data extensively to deeply
understand customer usage and then
close the gaps between product
hypotheses and business impact.”

@conorfi
Data can help you answer
Before we update this feature, how many customers are
using it?
If usage is low can we freeze or remove the feature?
When we deliver this feature what does success look like?
Can we create a user journey to represent success?

@conorfi
Suggestion
Have you already got data that could
help answer your questions?

@conorfi
7. Everyone can Test
“We expand testing abilities and
knowhow across the team;
understanding that this may reduce
(or eliminate) the need for a
dedicated testing specialist.“

@conorfi
Controversial?
NO – Context Based
Wording: reduce (or eliminate)
If you successfully implement the
principles, you will always be in
demand

@conorfi
Testing Knowledge & Skills
“Human-Centric Testing”
Janet Gregory
● Workshops
● Pairing and Mobbing
● Department/Company Bug Bash
● “Dogfooding”
Exploratory
Testing

@conorfi
Exploratory Testing
“Tested = Checked and Explored”
Explore It!
Elisabeth Hendrickson
Checking(Binary) - Known Unknowns (automatable)
Exploring(Open Ended) - Unknown Unknowns
A thoughtful approach which involves “simultaneous
learning, test design, and test execution”
Cem Kaner

@conorfi
Suggestion
If your team has a tester, what would
happen if they stopped testing?
What happens when they go on
holidays?

@conorfi
Potential Challenges/Concerns
Resistance to Change
Support for your Ideas
Concerns around Principle 5 and 7
“Dev don’t want to do test”

@conorfi
Learnings
Principles are a guide, not rules
Testers can be a force multiplier
Shared Ownership of Quality - no safety net
Importance of Collaboration & Communication
