Let's put you on the hot spot.  You are forced to agree or disagree with the following statement and defend your answer.

Deep subject matter expertise is irrelevant for a business analyst, especially in agile business analysis.

What would you say?

Here's how I answer:  I disagree.

My reasoning:  Actually I agree that deep subject matter expertise is generally irrelevant for a business analyst.  Where I disagree (strongly) is that it's especially true for agile business analysis.

Agile business analysis is no silver bullet.  It doesn't imbue you with magical powers to learn faster.  Failing faster to learn faster is simply churn.  There's no end to it.

We're missing the big picture.  Exploring 'deep subject matter expertise' you're not familiar with is a matter of having the right architectural tools to probe knowledge.  It's that deep operational business knowledge that makes subject areas hard.

So you simply need the right architectural techniques to map the knowledge of a domain explicitly.   You need to be able to ask probing questions about the domain intelligently without wasting SMEs' time.

The architectural techniques you need are true business rules and concept modeling (structured business vocabulary).  By the way, business rules and concept models can be made to work equally well for both agile and waterfall — and anything in between.
