Excellent training in "big company" processes. Raytheon (and their legacy companies) have a lot of "lessons learned" and these lessons made their way into the processes flown down to employees.
Cons
Raytheon is a process-heavy organization. As such, some processes exist that are perceived as non-value added. Upward mobility is limited in the NCS organization.
