"Individuals and Interaction" over "Process and Tools" doesn't seem like a great idea when developing software that handles life or death scenarios. Boeing, being the finatialized zombie company that they are now though have probably run some economic analysis and determined the optomal time to test / cost of life ratio. They must have determined that the cost of adequately testing their software is waaaaay more expensive than losing an astronaut here and there or some plebian passengers.
