Engineering — Patterns of Legacy Displacement

Patterns of Legacy Displacement

When faced with the need to replace existing software systems, organizations often fall into a cycle of half-completed technology replacements. Our experiences have taught us a series of patterns that allow us to break this cycle, relying on: a deliberate recognition of the desired outcomes of displacing the legacy software, breaking this displacement in parts, incrementally delivering these parts

Engineering — Risk-Aware Product Decisions in A/B Tests with Multiple Metrics

Risk-Aware Product Decisions in A/B Tests with Multiple Metrics

TL;DR We summarize the findings in our recent paper, , where we explain how Spotify’s decision-making engine works and how the results of multiple metrics in an A/B test are combined into a single product decision. Metrics can be of different types, and we consider success metrics (superiority tests), guardrail metrics (non-inferiority tests), deterioration metrics (inferiority tests), and quality
