So say Thank You.
If you work in anything resembling a ‘product team’, you have the responsibility to combine a multitude of perspectives into something resembling a business plan. For this reason, I believe that empathy is one of the most underemphasized qualities necessary for a successful Product Manager (in the Pragmatic sense).
Someone with a more siloed role is paid (not encouraged, but expressly given money and a business card) to treat their perspective as the most important perspective in the business.
So when someone screams ‘the sky is falling’, remember that means they’re awesome.
And say thank you.
