Outsourcing is not a fad. It has been going on for thirty years. Ever since Ford decided to dump its steel manufacturing way back when (prior to the "outsourcing" craze), people have been looking at ways to buy from someone else to reduce costs.
I don't imagine Boeing ever built much in the way of its own avionics? And I know they haven't built their own engines since P&W was forcibly split off along with United.
What? Ford doesn't even build its deisel motors anymore. GM
has outsourced almost all electronic components (granted many of them are to subsidiaries). IBM hardly builds PC
processors anymore, letting Intel and AMD do the innovation. I'm considering about a business start-up where the entire manufacturing process would be out-sourced.
Outsourcing is not a bad thing. It reduces costs for the company by asking someone else, who makes more than just your product, to take some of their capability to make part of your product. Since they are making more than just your product, they can use their economies of scale to make it cheaper. That makes your company leaner and meaner, and better able to compete.
Bad for the unions and employees? Maybe. But it's how business is done, and frankly how it's been done for many, many years. The future of the company comes first. If some people get laid off, that's just how it is.
Remember, the Board of Directors has a responsibility to the shareholders. They have responsibility to the employees, but not to the same level.
