As I recall, there was at least 1 engineer (who was sacked by Boeing) for telling them they needed more testing of this aircraft, especially the battery and electrical systems, before it should be put into commercial use.
In usual fashion the beancounters won out, the aircraft was pushed out the door so Boeing could book some revenue, and now the mess needs to be mopped up, and will end up costing far more to put right, than it would have if done properly in the first place.
