The problem
A 20-year-old leasing system that nobody had written down in over a decade. What each field means, which rule applies, which errors are normal: all of it lived in people’s heads.
What I built
Not a pile of documents. A system.

One main map of all the processes. Click a step and you land on its own page. Everything links to everything.

Every process page shows the same thing twice: a picture of the flow, and a table of the work steps.
- check_circle
The pictures are drawn from the data by a small program I wrote, so they always look the same and stay easy to change.

It is plain web pages. They open straight from a folder on a work computer, with nothing to install.
Proof
Delivered next to my daily support work, with one page template and strict naming rules so it stays tidy.
