What do we mean by an “Installed System”
‣
Any SIS - after all, they are all “installed”
‣
But more specifically, we are focussed here on
‣
Those installed before the standards were in place (“legacy systems”)
‣
Those installed in the early days of the standard
‣
Those installed when the standards were there, but weren’t followed
‣
Those installed to the standards with insufficient documentation
‣
If it’s not documented, it didn’t happen
‣
So “installed” not just “legacy”
