Application of hierarchical accident model in independent verification and validation
The software independent verification and validation (IV&V) is essential, especially in the development of aerospace systems, to improve safety and reliability and to prevent system problems. 12 We have used a hierarchical accident method. This method investigates the latent problems in the development process of a system that have not been thoroughly recognized in past IV&V.
