2、onary development（進(jìn)化式模型）Formal systems development（形式化模型）Reuse-based development（面向復(fù)用模型）,Waterfall model（瀑布模型）,需求定義,系統(tǒng)和軟件設(shè)計(jì),編碼和單元測(cè)試,集成和系統(tǒng)測(cè)試,運(yùn)行和維護(hù),Waterfall model problems（瀑布模型的問(wèn)題）,Inflexible partitioning of the pro

3、ject into distinct stages（僵化的階段劃分）This makes it difficult to respond to changing customer requirements（不適應(yīng)需求變化）Therefore, this model is only appropriate when the requirements are well-understood（適用于需求明確的系統(tǒng)）,Evolutiona

4、ry development（進(jìn)化開(kāi)發(fā)）,Exploratory development （演化開(kāi)發(fā)）Objective is to work with customers and to evolve a final system from an initial outline specification. Should start with well-understood requirements Throw-away prot
