This is a case of "if you need to ask, then you shouldn't".

That kind of statement is a little unfair don't you think?

Who is he more competent:

The person who understands some of the points required yet has some
"grey areas" in their knowledge - but dives in and "has a go" anyway,
or, the person who in the situation described, asks questions first
until they understand all of the required activities, and then does the
work?
