2、onary development（進化式模型）Formal systems development（形式化模型）Reuse-based development（面向復用模型）,Waterfall model（瀑布模型）,需求定義,系統(tǒng)和軟件設計,編碼和單元測試,集成和系統(tǒng)測試,運行和維護,Waterfall model problems（瀑布模型的問題）,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（進化開發(fā)）,Exploratory development （演化開發(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
