Both SRE and testing are looking at risks. Both are looking at areas of vulnerability and how we might model these to make them better understood so we can, in turn, mitigate them. Both have questions we need to consider, first and foremost being, “What happens if…?”

They’re common because they communicate practical information, but they’re not the only metrics we can employ. Here are three metrics you can easily create that will be very useful for your agile team.
Continue readingTest managers, leads, and practitioners often turn to the process of testing itself to gain these improvements. Even when testing is “good,” the question becomes, “Is it good enough?” Is that the right question?
Continue readingAs the test lead on our flagship product, I live in the backlog, and I breathe these bugs. A normal release for us fixes roughly 20 bugs that are unrelated to new work. With a backlog of about 200 bugs to choose from, I had to learn how to prioritize bugs and select the “right” ones for releases.
Continue readingI recently had the pleasure of running my tutorial, how to lead continuous delivery with Testing, at Agile Testing Days. With twenty-two students, the tutorial was well attended. What surprised me was the demographics.
