DevOps Days New Zealand 2018 talk. "Really? Testers do DevOps? Don’t swing from the fully sick enterprise waterfall model with battery hens of QAs gate-keeping releases & acting like bullish custodians of quality to the other end of the swing where we don’t need specialists, not Ops, nor QA. Where do your testers still add value?" https://www.devopsdays.org/events/2018-wellington/program/theresa-neate/

Testing & QA
“testing is an empirical, technical investigation of a product,
done on behalf of stakeholders, with the intention of revealing
quality-related information of the kind that they seek.” - Cem
Kaner
QA (Quality Analysis) is the entire process of building in and
raising awareness & ownership of quality. - Theresa

What does DevOps mean to me?
“... an umbrella concept that refers to anything that
smoothes out the interaction between
development and operations.” - Damon Edwards
Core values:
1. Culture
2. Automation
3. Measuring
4. Sharing

Closing the loop: Lean QA
17
The reduction of waste (rework, defects, friction)
by holistically testing the whole system, early
and continuously (even into production),
including measuring what really matters &
incrementally improving thereupon,
and employing your humans intelligently,
is Lean QA.
