I've worked with a number of GE businesses, if you give the GRC teams clarity of direction , they will deliver. If the problem statement is more like "we want to do something in wind", the end result may be something that you don't like. You'll be surprised at how many times businesses come to GRC without a clear statement of work. Whose fault is that ?
One would think if GRC were not there, suddenly GE would become 300$ stock ? Get a sense of reality guys. There were issues of size and scale of GRC, Vic's painful clearout a couple of years fixed that.
You own the product lines, you own the P&L, you own the quality. Look in the mirror if you want to see reason for decline.
