What does question followed by です mean?


仕事を抱え込んでしまって困った山田さんが、「なにを作るかよりも、いかに新しい作り方をするかです」と言ったって、説得力がない。

This means; Yamada who dived into a new job and got in trouble said "its less
what your make, but in what new way you make it", which was very unconvincing.

Is that right? im confused by the question followed by desu.




> 「 **なに** を作{つく}る **か** よりも、 **いかに** 新{あたら}しい作り方{かた}をする **か** です」

The part preceding the final 「です」 above is **_not_** a question even though it
contains "elements" of a question -- 「なに」、「いかに」 and 「か」.

> 「Interrogative word + verb phrase + **か** 」

in this context, as it often does, functions as a **noun phrase** just as in
"I don't know **_what to eat_**." in English.

Moving on to my next point..

> 「A + より（も） + B + です/だ/である」

means:

> "B is more important than A.", "B is more desirable than A.", etc.

Notice that there is no word needed in the expression that directly means
"important", "desirable", etc.

Thus, the whole sentence means:

> If Yamada, who himself is in deep trouble with too much work on hand, said
> "It is more desirable to think about new (and more efficient) ways to
> produce than to (just) think about what to produce.", it would not be
> convincing.
