Bob Haugen (Jun 08 2020 at 12:51):Has anybody done that or thought about it and wrote down some conjectures?
Bob Haugen (Jun 08 2020 at 14:22):I should probably clarify: I am very aware of the application of category theory to programming languages.
I am asking about application to the process of developing software, especially in teams: coordination of work, carving into modules, interfaces between modules, software repositories, version control, issues, commitments, pull requests, merges, etc.
Rongmin Lu thanks a lot for replying. I added my clarification at the time you were asking what aspects I had in mind, so our comments criss-crossed. Hope my clarification helped.

The programming language we (Statebox) are working on has exactly this kind of goal in mind
Jacques Carette (Jun 08 2020 at 23:43):I am actively working on using category theory to carve things into modules (and give combinators to assemble them). See in particular https://arxiv.org/abs/1812.08079. The work of my PhD students Yasmine (https://scholar.google.ca/citations?user=yl8yHj0AAAAJ&hl=en and the latest work buried in https://github.com/ysharoda/tog) and Musa (https://github.com/alhassy/next-700-module-systems) are suffused with categorical thinking applied to software. The reason I became co-maintainer of agda-categories (https://github.com/agda/agda-categories) was to learn even more CT that I could apply. If you leaf around https://github.com/JacquesCarette/, https://gitlab.cas.mcmaster.ca/MathScheme and http://www.cas.mcmaster.ca/research/mathscheme/ you ought to see lots of 'categorical thinking'.
[Sorry for the self-promotion; but the question was asked, so I guess it's fair game!]

Thanks, Fabrizio. I have been following Statebox, but alas, am hard at work on a set of projects using more primitive programming languages. Maybe in my next life, or maybe I can find a project using Statebox to manage distributed economic networks (my focus), or maybe somebody involved with Statebox wants to start one?

Definitely fair game, Jacques, and thanks for all the links. I see some really interesting and promising ideas amongst them, but mostly over my head given my infant stage of acquaintance with category theory. I will dig into some of them and see if I can understand.
