Wayfair’s engineering team has more than 1,300 engineers. Its many small sprint teams work efficiently and effectively on their own, but as the company has grown, engineering has experienced challenges in collaborating across the department. To address this, Wayfair introduced a concept called working groups, based on InnerSource principles, that lets the engineering team run these kinds of projects with the efficiency expected from any other team. Adam Baratz offers an overview of how Wayfair structures its working groups, details their pros and cons, and explains how the company plans to iterate on this pattern. Adam then shares examples of projects Wayfair has tackled with working groups.
