RESULTS FROM AN INDEPENDENT VIEW ON THE VALIDATION OF SAFETY-CRITICAL SPACE SYSTEMS

摘要

The Independent verification and validation (IV&V) hasbeen a key process for decades, and is considered inseveral international standards. One of the activitiesdescribed in the “ESA ISVV Guide” is the independenttest verification (stated as Integration/Unit Test Proceduresand Test Data Verification). This activity is commonlyoverlooked since customers do not really see the addedvalue of checking thoroughly the validation team work(could be seen as testing the tester’s work). This articlepresents the consolidated results of a large set ofindependent test verification activities, including the maindifficulties, results obtained and advantages/disadvantagesfor the industry of these activities. This study will supportcustomers in opting-in or opting-out for this task in futureIV&V contracts since we provide concrete results fromreal case studies in the space embedded systems domain.
