Automotive claims they have caught up and closed the gap with the leading software companies in six, seven years. I think the opposite is rather true. The gap has widened.

I wrote a blog post a few years ago, how dysfunctional project management can be. Later I heard from an insider how an automotive company in Gothenburg had removed a whole layer of project managers – no one could see a difference.

Microsoft CEO Satya Nadella knows how companies will be managed in the future. Companies that can’t adapt won’t survive. Today’s lacy management culture, hiring people to solve problems, will disappear or wreck companies.
