At work, I'm a contractor and I typically spend 1-3 years on a project. Each gets its own system, nice and simple.
My home system has 10-19 capturing all of my 'personal, daily life' which leaves plenty of areas for my personal projects. For instance, 50-59 is Johnny.Decimal itself.
So far I've implemented JD:
- Managing a 2 year contemporary dance production, multiple locations, staff, ticketing, marketing, etc.
- Consolidating 200+ data centres in to 7; I did basically all of the hardware from procurement to having a green light on a NIC.
- Running an infrastructure upgrade project for a major bank.
- Running 2nd level desktop support for an international packaging company.
- My personal life, including managing the limited company that I contract through.
I plan on anonymising and documenting as many of these cases as I can on the site. I just need to find the time.
