a project group that technically no longer exists

Age: 2.9 years · originally expected to last 3 months · 3 owners so far · survived 2 reorganisations · last meaningful change 823 days ago · original builder left 1028 days ago

Rated common mostly because: 2 departments depend on it, the builder has left, alive 12x longer than intended.
