Is an ATS a solution or a tool?

Via JobMachine …

A person buys the best hammer in the world only to discover that it doesn’t change their ability to hammer a nail.  Sounds silly, yet companies that set out to buy what they’ve determined is the best ATS often find nothing has improved a year after installing it.  Their mistake is buying an ATS thinking it’s a solution, when in reality, it’s a tool only as effective as it is used.  The irony is companies who install ATSs often end up in worse shape than before, through no fault of the ATS vendor.
