Classification of air on-board software code defects and investigations

Software defects classification is the basis for effective management of software defects. Current air on-board software testing classification GJB 437 is too easy, coding defects classification in other software defects classification does not meet our air on-board software code review facts. The deficiencies of existing classifications of software defects are analyzed. And a classification for air on-board software code defects is presented. This classification is verified and completed by investigating the historical code defects of air on-board software. The revised classification has covered selected historical defects perfectly. The results of verification show that the revised classification of code defects can guide defects management effectively. At the same time, defects database is established using typical air on-board software code defects. Defects management is implemented based on defects database, guiding software defects detection and prevention.
