Construction projects often suffer from a strict zero-tolerance error culture that discourages transparency and learning. A new study in Engineering suggests embracing unintentional action errors as inevitable opportunities for improvement. By shifting to error management with open communication and psychological safety, firms can boost learning, reduce hidden risks, and enhance long-term project performance. The piece calls for more research to support this constructive shift in the construction sector.
