What does "traceability" mean in programming?
traceability is one of the most common terms in software development. This guide explains what it means, how it is used in practice, and why it matters, with real examples from the developer world.
Definition
The ability to track how requirements connect to code, tests, and deployments — and to follow a request through every service it touches at runtime. Distributed tracing tools like Jaeger and OpenTelemetry provide request-level traceability.
Example
"With distributed tracing, we have full traceability — we can see every service call a user request triggered."
