What happens when people make a mistake at work? That depends on the culture of the organization- covering it up or passing the buck are options when competition drives behavior or if there is a low trust environment. But at Etsy, employees are not only asked to own up to their errors but reveal them to the entire company.

In a recent piece on Quartz, Etsy CEO Chad Dickerson revealed that people at the company are encouraged to document their mistakes, how they happened and what they learned from it, in public emails. The company “also gives out an annual award—a real three-armed sweater— to whomever who made the most surprising error, not the worst one, as a reminder to examine the gap between how things are expected to happen and how they actually do.”
