It determines how the various results are computed by the product and presents this information in the form of a (7) and associated scenarios. The second is (8) , which determines the classes and their attributes, then determines the interrelationships and interaction among the classes. The last step is (9) , which determines the actions performed by or to each class or subclass and presents this information in the form of (10) .

解析：[参考译文] 面向对象分析是一个面向对象的半正式化的规范技术。它由三个阶段组成。第一阶段是用例建模，通过用例建模能计算出多种结果，并以用例图和相关场景的形式体现这些信息。第二阶段是类建模，通过类建模能够确定类及其属性，在此基础上就能确定类之间的内部联系和变互作用。最后一阶段是动态建模，通过动态建模能够确定每个类及其子类的行为作用，并以状态图来体现这些信息。
