Ring-fenced

Here is an illustration of the bullshit management expression 'ring-fenced'.

Car surrounded by shopping trolleys - ring-fenced!

What they don't tell you (I speculate) is that, like in the management equivalent, the fence does not actually meet at the other side.

This gives the illusion of safety but belies the chance that your resources will be allowed to escape before you finish the project after all.

Experienced project managers develop ways to cope with disappointments like this!
