Markdown and pandoc are like match made in heaven for this. If you didn’t know, Markdown is plain text file, has a simple syntax for formatting (that gets carried over when you use pandoc), supports LaTeX equations and can attach metadata as yaml part on top of the file (gives custom usability when pandoc works on it). And pandoc is document converter between multiple formats and can produce word files, PowerPoints, html file, latex pdfs (book, report, Beamer presentations) etc. You can also provide a template for pandoc to work with and it produces in that format. Not to mention since it’s plain text, you can apply git version control and also use make files to iteratively compile new outputs.

There is also RMarkdown (or it’s newer successor Quartro), which is same markdown pipeline but also can compute codes inside a section and attaches the result to the markdown file and does the whole pandoc thing afterwards. Think of it as like Jupyter Notebook style of literate programming with Markdown. Here’s a demonstration of its capabilities. youtu.be/_D-ux3MqGug

Assuming your colleagues can work with git but not LaTeX, you can set up a git repo with just markdown files and collaborate on that and have a makefile or docker container to get the final word or pdf generated. Here’s a good example of an pandoc makefile gist.github.com/kristopherjohnson/7466917

In Worst case scenario that they only work with word files, you can generate one from your markdown files and share with them and pull down the changes they sent you on the word document.

P.S. I assume Org-Mode can also substitute Markdown here in the pipeline. But I haven’t committed to it, so I’m not fully sure.
