Ahead of her AutomationSTAR Deep Dive, Close Encounters with Systems, Rachel Kibler reflects on the skills that shaped her testing career—and how systems thinking gave her a name for what she was already doing.
I started my career by diving headfirst into the context-driven testing community, forming some very strong opinions along the way. I look back at my dogmatism and wonder why I was so convinced that I, a baby tester, was right just because I was parroting something persuasive that resonated with me.
I found my way to conferences, which broadened my horizons and showed me that yes, everyone thinks in terms of context, and the arguments that we have within our testing community can be tiresome, worn-out, and ultimately unhelpful, even harmful when they gatekeep and manufacture heightened emotions around who’s doing testing “the right way”.
Ten years in, I hold a lot of my strong beliefs still, but considerably more loosely, and I’ve become much more understanding of everyone’s journey. Turns out, not everyone needs to do things the way I do them!
In addition to my attitude shift, I found that the skills I learned early on formed a lot of what I care about and still think about. And that these skills that I value turned out to be systems thinking before I had the words for it. Elisabeth Hendrickson’s book, Explore It!, was massively influential in learning how to create test charters and organize my mental models, as was Janet Gregory and Lisa Crispin’s Agile Testing in thinking strategically about how to deliver quickly and not be a bottleneck.
James Whittaker’s How to Break Software was one of the earliest I read, and though he does spend a lot of time on printer testing, the idea of creativity in your testing by shaking up the machine (sometimes literally) was helpful. And doing the Black Box Software Testing foundations course by Cem Kaner and Rebecca Fiedler through the Association for Software Testing played a huge role in shaping my skills too.
Because of those influences, I learned to think about software in creative ways, to not trust what someone says the software does and does not do, and to spend time following my gut instincts about where things could be broken, largely at the boundaries of the software and the boundaries of our understanding of the software.
I learned how to communicate well with my developers and at the right time. I learned how to advocate for my bugs, and hopefully for the user. I learned how to identify risk and to bring people together for conversations about what matters and what quality is for our products, creating feedback loops and shared mental models. These skills felt good to me, they felt right, and they enabled a solid career with good delivery of software.
Some testing skills eluded me though. Writing extensive documentation has never been my strong suit, and though I do strongly believe that test management systems are a kindness and should be a system of record for our software, writing steps down in depth has always felt daunting and overwhelming to start with. But documentation does make our system legible to others, modeling what we understand to be true. I also never really got a handle on what my automation should look like when it’s at its best, when it’s giving the feedback on the system in the right place.
AI changed the game for me, enabling me to pay more attention to the “what” and the “why” of automation rather than the “how” that had been so much of the concern of past me. However, thinking about documentation and automation in terms of systems may be the thing that drives both of these forward for me.
For AutomationSTAR in Antwerp this November, I get to do a deep dive into systems thinking itself. I’ll give a brief overview of the concepts in systems thinking before we dive deeper into time delays and other less intuitive things, pulling heavily from the new work of Elisabeth Hendrickson and Joel Tosi (their book, Signals & Levers, releases on September 22nd, 2026) as well as the work of Donella Meadows (Thinking in Systems: A Primer) and many others. Learning from Elisabeth Hendrickson’s book at the beginning of my testing career and now from her new book with Joel Tosi seems fitting.
I didn’t invent any of this, it’s been around for a long time, but it’s more relevant than ever right now. Systems are becoming more and more complicated as we throw AI into the mix for both the software itself and the processes around it. Feedback loops are getting longer and stranger, and the levers to pull are moving. Testers talk about systems in daily work, but perhaps without the structured framework to make the conversation’s importance clear. Systems thinking gave me language for the things I learned to do by instinct or by mimicry, and I’m excited to pass that on so you can talk about the things you already do and care about in terms of systems.
