What do you mean by moving and inter-dependent parts ?

I read doc (if any), talk with different people, although it's none in my team (T_T), then identify different services or processes, read their logs a lot, then glance through code structure + file names, then put thread dumps, then somehow found it.

Then explore around something, add more logs or use a debugger - run it locally or on cluster, then speak with people - share my findings, then they'll ask few more questions or explore on their own - this will happen for a week.

This way you'll exponentially (whether you remember that info is a different topic) gain knowledge + faster turn-around time for any poc or incremental feature change.

Ultimately, everything is a kernel process with some threads running in it. So, yeah attack codebase in anyway possible.

By moving parts I mean components in a system which change state, and communicate with other components. Anyway, yes, reading docs I guess is useful, usually out of date though. Yeah, good tips on trying to read the logs, to understand how the parts interact and get a mental model. Thanks for the tips
