The Insourcing Boom
I found the story they give about GE forgetting how to make water heaters interesting.  The line you usually hear about startups creating their core technologies in house and outsourcing non core things comes to mind.Was GE originally known for manufacturing (or ability to manufacture) and then lost that core ability?  If they did, what would their core ability be after outsourcing, management of manufacturing?  Maybe I'm not making a good connection there, but I think it could be.
