How about Quality Control? It's outside your field, but...
Literal
Different-field [of-の] quality-control-section [topic-は] how [copula-です][question-か]?
畑違い literally 'different field (of cultivation),' used metaphorically for 'outside one's specialty/expertise,' here modifying 品質管理課 attributively. 如何 (いかが) is the polite counterpart of どう 'how,' also common in keigo and formal writing. The sentence has the feel of a workplace reassignment discussion — offering the listener a transfer to Quality Control while acknowledging upfront that it's unfamiliar territory.
