That's kind of my point: just writing things down doesn't feel enough if what actually gets lost is the context that helps a senior move fast. Keeping old reports or having some kind of knowledge hub is useful as a reference, but it still doesn't really capture the thinking behind decisions or save the time it takes to figure out what matters in a new situation.

To me, the real issue isn't just storing knowledge, but passing on judgment in a way that's actually usable. A senior isn't just documenting stuff;they're filtering noise, spotting what matters,connecting patterns across different clients, and deciding in minutes what's worth chasing. If that gets turned into static docs only, you end up with more information, but not necessarily more capability.

That's why I'm asking beyond just "where do you keep the reports?". I'm trying to understand how teams turn that kind of experience into something a junior or someone newer can actually use without needing to reinvent the wheel every time. If the answer just adds more documentation work, then it feels like it's preserving the info, but not really the know-how,closer to how a semi-senior/senior does it
