How does this differ from a second opinion?
A second opinion gives you a judgement: what is going on, which options you have and what each one costs. What you do with it is yours to decide. Recovery means I take the wheel and am answerable for the progress. The second opinion is the cheaper first step when you do not yet know whether the project can be saved. Recovery is the step after that: by then the problem is no longer that nobody knows what is wrong, but that nobody is acting on it.
