Table 5: _Cont._Table 5 indicates that the criticalities of software and hardware failures of the C\({}^{4}\)ISR system are comparable, which demonstrates that for both the design and the operation stage of the mentioned system performance and failure properties of the software and hardware of the C\({}^{4}\)ISR system should be focused on. This conclusion also indicates that failure properties of software and hardware integrated systems are consequences of the both software and hardware failures which would be different from the maturely implemented software systems and hardware systems. Additionally, applicability and feasibility of the GO methodology for the reliability analysis of software and hardware integrated systems are valeted.
