Wow, that is impressive. Norway is surely advanced in humanities.

So, why not publicise the performance metrics of the employees as well? Not public at least accessible like what you mentioned on salary. I'm not questioning why Norway isn't doing it but in general why not?

Such access to performance can also serve as a driver in the employment industry. Along with the engineering blogs, one can display links to the portal with company attested achievements and stats, it will at least reduce false claims in LinkedIn.
