We hear the phrase “build quality in” all the time, but how do we actually do that? This talk looks at human-centered design and the design of doors and other everyday things to explore how subtle aspects of design can help us build in quality much more effectively. This talk builds on 10+ years of experience transitioning from a software tester and “quality gatekeeper” to someone who supports teams building in quality. We will explore stories, perspectives and practical advice from that journey.
