I once worked as an engineer for an engineering company (for engineer read technical specialist or scientist not washing machine repair man). They interviewed us all for our own jobs at one point, and oddly the only criteria was "management skills". As the mods on here will know I don't have any of those, and most of the other technical specialists also left the company.
The wider context is missing from the article. They mention that Google will train staff to help them become better managers. That suggests the managers working for Google also have other useful skills.
Failing companies tend to treat management as a specialism on it's own - That side of things will be completely missed by the Google study. I get the impression Google is a good place to work.
