I have selected ALL

...or not and.

So, it could be great if you are able to edit again the poll by adding "all of them", "part of them" and "depends on strategy and/or the customer".

then I will prefer the "depends on strategy and/or the customer".

I can only disagree.

It (the quality) will depend on the time and effort taken to develop it.
