In two non-profits, I'm using GroupSpaces for simple project management. One
page per project (a formatted wiki) quickly brings structure. These are
non-profit organisation with zero or few employees, so we must keep things
simple. I use these pages as "seed corn" - in Prince2 terms, I write the
"Project Mandate". The project team then updates the same page (using the
wiki facility) to create a mini-PID; which they subsquently update
periodically to create a rolling highlight report. All on one page. Simple
but very effective. A big thanks to GroupSpaces.
