I always wondered this:

If you are an external consultant (with no prior knowledge of the company's systems/processes/hierarchies) brought in to "fight" a particular fire, how do quickly get ramped up to a level of knowledge where you can analyze the root cause of/recommend a fix for a particular "fire"?

I would say the analysis is 90-99% of the work, based on my experience. Especially the more jacked up systems where cheapest devs found work on the codebase and it's a mess. 90% only comes in when it's so jacked up it requires a lot of refactoring.
