>Bug resolution time depends on how familiar a developer is with the system, how complex the issue is and how impactful the bug is

Some huge factors are:

- how fast you can test things (e.g. change and re-run test)

- how good runtime (e.g. debugger) and logging visibility you have

- how good (representative) are the test data

In other words, fast ways to "look into" the matter. Usually if you can iterate fast and get a reproduction, you can also solve it fast.

It's much less common that the issue is a big architectural concern that needs total rethinking/refactoring.

Biggest factor, dwarving all the other factors: can you quickly repro.
