The workshop provides a model for the deep, insightful inquiry that occurs when technical groups collaborate on anomaly analysis.

Yet we know little about how they accomplish this vital work and even less about how to support them better in doing it.ĭuring the past year a consortium including Etsy, IBM, IEX, and Ohio State University has explored issues around software engineering as it related to internet-facing business platforms. These platforms remain alive and functioning because workers are able to detect anomalies, diagnose their sources, remediate their effect, and repair their flaws and do so ceaselessly - SNAFU Catching. Without the continuous effort of engineers to keep them running they would stop working - many in days, most in weeks, all within a year.

The themes that emerge also highlight opportunities to move forward.Ĭurrent generation internet-facing technology platforms are complex and prone to brittle failure. These cases reveal common themes regarding factors that produce resilient performances. Woods' Theorem: As the complexity of a system increases, the accuracy of any single agent's own model of that system decreases rapidly.Ī consortium workshop of high end techs reviewed postmortems to better understand how engineers cope with the complexity of anomalies (SNAFU and SNAFU catching episodes) and how to support them.
