There’s a major divide between the way scientists and programmers view the software they write.
Scientists see their software as a kind of exoskeleton, an extension of themselves. Think Dr. Octopus. The software may do heavy lifting, but the scientists remain actively involved in its use. The software is a tool, not a self-contained product.
Programmers see their software as something they will hand over to someone else, more like building a robot than an exoskeleton. Programmers believe it’s their job to encapsulate intelligence in software. If users have to depend on programmers after the software is written, the programmers didn’t finish their job.
I work with scientists and programmers, often bridging the gaps between the two cultures. One point of tension is defining when a project is done. To a scientist, the software is done when they get what they want out of it, such as a table of numbers for a paper. Professional programmers give more thought to reproducibility, maintainability, and correctness. Scientists think programmers are anal retentive. Programmers think scientists are cowboys.
Programmers need to understand that sometimes a program really only needs to run once, on one set of input, with expert supervision. Scientists need to understand that prototype code may need a complete rewrite before it can be used in production.
The real tension comes when a piece of research software is suddenly expected to be ready for production. The scientist will say “the code has already been written” and can’t imagine it would take much work, if any, to prepare the software for its new responsibilities. They don’t understand how hard it is for an engineer to turn an exoskeleton into a self-sufficient robot.
