Interesting thread direction.
MS office is "one of those things". I've used it extensively, from writing 500+ page technical documents over the space of 25 years, to an API level down to writing huge VSTO plugins to do runtime templating etc. I know office better than most people do and I know how to use it properly and I know where it sucks.
The workflow is fundamentally broken if you're sharing stuff. It really is a complete shit show. Even between office versions there are issues. The only place it works in this capacity is across total version consistency across everyone and then there are so many edge cases, gotchas, problems that costs increase massively. I've seen financial advisors crying into their tea after spending a week writing portfolio reports for people in it only to come back and find the document is toast. So they came up with Office 365 which sort of enforces version consistency by taking it away and gives real time collaboration tools. This introduces another thousand concerns that most users don't want to deal with at the same time and breaks working practices. So what happens is you end up with 9 different versions of office and people emailing shitty documents around still or editing them on a file share back like it's 1999 again.
Alas my patience for this shit is very very very low. So I use Libreoffice myself. Sheets, writer, draw. Impress is cancerous as is powerpoint. Low information density. You can't pay me to write powerpoints
. My workflow moved to actually receiving pieces of poo in docx format, cut and paste them into notepad2 to remove all meta-formatting and then assembling them carefully into writer. Once complete this is turned into a PDF and mailed back for review. The document itself NEVER leaves the owner's machine (other than for DR) and is never touched by another human. Edits and reviews are done by email by sending text content only however they wish to spew it at me.
The outcome is reliable, fast, well controlled and importantly does not specify which technology to use. I could switch to LaTeX tomorrow if I could be arsed with it and the outcome would be the same. And after all it's the document that's important isn't it, not the tools. Turns out the focus on the tools not the working model is what is costly and complex and requires maintenance.
