The purpose of the QA and staging part of the SDLC is to test software and – assuming it meets quality requirements – prepare it for deployment into production environments. To do this, engineers need to be able to identify performance or reliability issues that exist within the application.
At the same time, though, they must ensure that their data is actionable, and that it helps them quickly fix issues, in order to avoid holding up the SDLC. For QA and staging, then, logs must provide refined data that allows engineers to anticipate what will happen in production, and helps them get to the root cause of any problems they detect.
