I work in a company that shifted from being R&D-driven to being project-driven. It is official since this 2013 but we saw it coming: the main pieces of memory are Powerpoint slides since a few years.
Everything is in Powerpoint, from agendas, discussions, presentations to minutes. Even when modelers want to show some results, they put them on a slide deck first …
For presentations I used to use Beamer but installing the LaTeX toolchain on a restricted, company-owned Windows laptop was a long and cumbersome process. I made a first presentation in Reveal.js this week. And I love it!
I prefer Beamer, Reveal.js and similar tools because a) it forces you to think of your message and its structure first and b) it forces you to reuse material that is already produced (rather than creating new things in / for the presentation medium). Therefore the presentation is a real presentation of something that really exists, that was really thought outside of the context of the presentation (and before it!).
The additional benefit (IMHO) of Reveal.js is that you just need a text editor and a browser. All restricted company laptops provide you with these tools.
The memory of my projects remains in my models, my notes and reports. The context, next steps and consequences are there. The project evolution is better understood (in reviews, audits and simple chats with colleagues).
