Yup, keep bickering, since whatever you do is not going to help you survive might as well blame somebody else so you feel less guilty of your own arrogance and failure to work with the others in GE as a team. The culture compass says it all - things within own team are great and things needing other teams are bad, well funny, everyone's team is someone else's other team…
If engineering did not support sales, these HA would not be in the catalog for another 2 years because there is just no way they can be properly designed and tested before they are ready for prime time. The fact of the matter is engineering did support the pipe dream of sales team so GE can get the contract first and take the chance on design not matured enough - just fix it later, no big deal. That's the philosophy of the GE Power leadership and now the bubble burst all of sudden it's the guys and gals that said you are taking a lot of risk got blamed for failure instead of the persons taking the risk to get their numbers and bonuses.
Siemens paid their engineers better than GE Greenville and what they just signed with Duke is a 7 year NPI project - the plant will not get to its promised output until 2024! HA02 design work started in 2014 and in less than 7 months GE started selling it and less than 3 years it's in customer site running - is it really surprising that it's going to have problem?
