I know of a company, made up of scientists from academia, that develops software by writing the code (or "codes" as they call it) in Microsoft Word documents and e-mailing them to eachother.
Oh my god yes. As someone who cut their teeth developing software for pharmaceutical research, I can testify that a much of it is absolute crap, by a variety of metrics.
It's funny how this exact same mistake is made in the linked paper. For some reason, people outside of IT can't get it into their minds that "code" is an uncountable noun in this context.
Some how, they are still in business.
True story.
