Was that your personal metrics? Metrics created for yourself are subject to less gaming because when you start lying to yourself about those, you will start to wonder why keep those metrics at all.

If that was a company-issued, top-down metric, I hope it wasn't defined literally as "helping n people in a different department", because that has enough wiggle room to sail an aircraft carrier through. The difficulty of creating a good metric here comes from the difficulty of defining what exactly does it mean, in company context, to "help other people" - and also what it explicitly doesn't mean.

I had to report it to my boss. It was top down, but only a few interactions were required, and it wasn't reported farther up the chain. Because I had to report to my boss, he knew me well enough to judge if it was enough. It was just enough of a metric to ensure people looked for something to bridge a communication gap, without being hard enough that people tried to game it much.
