I work for a state government. Some of my peers are handling the response for the whole state so they've been open to people working from home. There are notices everywhere of washing hands and not touching your face. Anyone who has traveled recently has been requested to stay home as well.
It's less any one element of the concept than the fact that it's immensely negligence-tolerant. Sort of like quitting smoking: you can do it a thousand times, but it's so easy to pick up again.
That and the notion of an index, which is IMO key to the whole concept, moreso than the bullet notations and other organisation.
After resumability and index: spreads. Basically, an idea hits you, take a two or four-page section, title it, add it to the index, and collect thoughts on That Thing there.
One early spread I did (and still maintain) is "How to organize BuJo" (or words to that effect). Pages wanted, management ideas, etc. List things you might want to manage, figure out how to do that, and then ... Just Do It.
I make a practice of starting from the front and back of the journal, with more-fixed references (frequently-called numbers / email, reference information, hours of operation, Significant Other details (dates, measures, etc.) in the back, whilst various projects tend to hit where they occur to me in the course of a year.
(And yes, I've been starting a new journal each year, a bit of housecleaning / stop-lossing.)
The manual overhead (numbering pages, adding month overviews, etc.) is slightly tedious, but also a practice-of-presence and/or awareness that helps focus the mind and encourage review.
The Bullet Journal site itself is pretty good (https://bulletjournal.com). There are numerous very artsy BuJo videos on YouTube. I tend to discourage those -- BuJo is a functional tool, but also a personal tool, and the notion of competitive BuJo strikes me a bit like competitive yoga: spectacularly missing the point. If your muse says "glitter-gun and washi-paper All The Things", then great. But if not, a well-used but non-artistic BuJo beats the pants off one that would feature well on Instagram or Pinterest.
I work for a state government and we've actually implemented exactly the solution outlined in this post. The business side of things still created that big document, but then we have a product owner who broke that down into things that the development team can consume. As a developer I can just look at what's next on the list and implement it how I want. There is still a lot of red tape, but it is definitely getting better.
