Ronnie Chen, an engineering manager at Twitter and a technical diver, shared insights into managing failures during his talk at Chaos Conf 2018. Drawing parallels between technical diving and complex systems, Chen emphasized the importance of preparation, training, and judgment in handling failures. He recounted his experiences with technical diving, highlighting how a combination of training, real-world practice, and an understanding of complex failure patterns is crucial for survival. Chen argued that focusing solely on a single failure factor is simplistic and that understanding the interplay of multiple factors is vital. He advocated for practices such as pre-mortems, fire drills, and empowering less experienced team members to lead, as these strategies can enhance a team's overall competence and preparedness. Ultimately, Chen suggested that success in complex systems is often unrecognized because it results from quiet, incident-free operations, rather than dramatic recoveries from failures.
