Abstract: There are two main problems in developing a software based on the waterfallmodel: the semantic fault and the adaptability to the requirement changes.Both the object-oriented method and the prototype method have obvious superiority in tacklingthese two problems. During the development process, it has been proved that the object-oriented method is better for tackling the former problem while the prototypemethod is better for tackling the latter. Therefore, people are attempting to combine thetwo methods in one and form an object-oriented prototype method. This paper gives animplementation strategy for the object-oriented prototype method and lists three necessary steps during the development by using this method.
