I have a form for a medical check-up that asks what category best describes the 業務内容 of your occupation.

One of the choices is 技術・研究 and another is 生産・技能.

A monolingual dictionary is of no help because it defines 技能 with 技術.  

I can't decide between 

> 
> Technology/Research and Manufacturing/Crafts  
> 
>  and  
> 
>  Engineering/Research and Manufacturing/Technical 
> 
> 
> 

but engineering for 技術 seems like a bit of a stretch, especially because I don't see it being lumped together with research. 技能 being categorized with 生産 makes me think it's more along the lines of "skilled worker" but that's not a category of occupation. 

I also referenced [this Wikipedia page on categories of occupations](https://en.wikipedia.org/wiki/International_Standard_Classification_of_Occupations). Which had **Skilled agricultural, forestry and fishery workers** and **Craft and related trades workers**. I wondered if 技能 could be so broad as to include both of these, but being put with manufacturing makes me think it is only crafts.

So, when referring to an occupation, does 技能 mean something as specific as crafts and is 技術 referring to all technical fields?  

Or is 技能 technical fields and 技術 more specific as in engineering?

Thank you for any help sorting this out.

Note: I have already seen [this question](https://japanese.stackexchange.com/questions/3829/what-are-the-differences-between-%E6%8A%80%E8%A1%93-and-%E6%8A%80%E8%83%BD). It didn't help.
