👉 Cancellation engineering is a design strategy used in software and systems architecture to mitigate the impact of failures or errors by intentionally removing or isolating components that, if they fail, could disrupt the overall system. This approach involves identifying critical paths and dependencies within a system where the failure of one component could cascade and cause significant issues. By strategically removing or decoupling these components, engineers can ensure that the failure of a single element does not lead to system-wide collapse. This method enhances system resilience and reliability, allowing the system to maintain functionality even when parts of it fail, by leveraging redundancy, graceful degradation, and failover mechanisms.
