What does 担当部署 mean?

担当部署 means the department in charge, the responsible department, or the division handling the matter.

• 担当 = in charge of something / responsible for something
• 部署 = department / section / division

So in this sentence, it refers to the office or department that will handle the matter, but that department has apparently not been decided yet.

Why is が used after 担当部署 instead of は?

が marks 担当部署 as the grammatical subject of 決まっていない.

So the structure is:

• 担当部署が決まっていない
• The responsible department has not been decided

Using は would also be possible in some contexts, but it would sound more like you are setting 担当部署 up as the topic for contrast or discussion.

Compare:

• 担当部署がまだ決まっていない
  = The responsible department hasn’t been decided yet.
• 担当部署はまだ決まっていない
  = As for the responsible department, it hasn’t been decided yet.

In this sentence, が sounds natural because the speaker is simply stating the situation.

Why is まだ used with a negative verb? I thought まだ meant still.
