The Scientific Method for Resilience

Wednesday, March 16, 2022 - 4:10 pm4:30 pm

Christina Yakomin, Vanguard


Do you remember the Scientific Method from elementary school science class? It's time to dust off that knowledge and use it to your advantage to test your IT systems! In this session, you'll be re-introduced to the Scientific Method, and learn how Vanguard's software engineers and IT architects draw inspiration from it in their resilience testing efforts. They leverage a "Failure Modes and Effects Analysis" technique, in which engineers ask themselves questions about the failure modes of various technical components and develop hypotheses based on their expectations of how the system would behave. They use these conjectures as inputs into experimentation, and select chaos experiments accordingly to validate (or disprove!) their hypotheses.
