Laura Maguire sheds light on how engineers and their practices, tooling, organizations, and vendors interact to produce great code, stellar reliability, and minimal tech debt. . .or not. Expanding upon the 2017 STELLA report from the Ohio State University Cognitive Systems Engineering Lab and fresh data from the second cycle of the SNAFU Catchers Consortium, Laura focuses on a critical aspect of DevOps practices—coordination. Aspects of social coding such as pull requests, daily stand-ups, or wikis just wouldn’t work without it and key tools such as GitHub or Slack literally exist to facilitate it. In studying incident response across digital service organizations, she’s found coordination is a highly complex, nuanced, and sophisticated aspect of modern software engineering.
Using case study examples, Laura explores how coordination is both engineered through top-down decisions (as defined by vendor agreements, organizational structure, tech architecture) but also emergent through bottom-up practices (as defined by the strategies and techniques practitioners use) to successfully carry out joint activity. She discusses how some methods of coordination can increase attentional costs for members of the engineering team, which can slow down problem identification or resolution of complex system outages, and offers promising directions for controlling these costs. She shares insights about complex coordinative functions incident response engineering squads share with high-performing teams across high-risk, high-consequence domains and provokes you to start exploring new ways to lower the costs of coordination within your own squads.
Laura Maguire studies human performance in high-risk, high-consequence work. As a researcher with the SNAFU Catchers Consortium, she has spent the last two years studying critical digital infrastructure and the teams tasked with keeping them running. She has a master’s degree in human factors and systems safety and is currently completing her PhD in cognitive systems engineering at the Ohio State University.
