摘要
PROBLEM TO BE SOLVED: To evaluate a test item or a check item prepared for objective software from the point of view of software reliability, and to extract the irreducible minimum item. SOLUTION: A software block diagram 3 is prepared based on product specification 1 of software, and a software behavior description and an extended activity diagram 9 are generated therefrom, and any abnormal operation factor is extracted from the extended activity diagram 9 by a deviation analyzing part 10, and a software defective tree 13 is generated by using them. A check item 16 is generated by a check item generating part 14 by using the generated software defective tree 13, and an already existing check item or a test case 17 is evaluated so that the absolute necessary item can be extracted from the point of view of reliability.
