@n8 @mlinksva I heard many times over the years that research software tends to "not up to professional software engineering standards". Not having a requirements document is part of that.
In my experience, in the software industry, very little software of any kind has a requirements doc, at least not a useful one, never mind anything else that one might expect of quality software.
I'd like to sit down with researchers, specifically, to discuses how to improve this, some day.
