(Dispatch from the Scenius) Elisabeth Hendrickson’s 2014 and 2015 DOES Talks on Feedback Loops, with Commentary from Gene Kim

The Idealcast with Gene Kim by IT Revolution

In the second installment of The Idealcast’s Dispatch From the Scenius series, Gene Kim explores Elisabeth Hendrickson’s 2015 and 2014 DevOps Enterprise Summit presentations.
Listen as Gene breaks down Hendrickson’s experience and learnings, all to help you find fundamental principles to apply to immediately keep your feedback cycles healthy and happy.

In this episode, Hendrickson, an experienced QA engineer, shares her realization that the better she got at her job, the worse she made things for the organization as a whole. Thus began her journey to uncover the relationship between testing and quality, which has led her to a reality of increasingly tight feedback loops.
