To be able to avoid these problems, software project management methods focused on matching user requirements to delivered products, in a method known now as the waterfall model.Vikas wariyalShreyank guptaVaibhav kumar

1.瀑布模型(Waterfall Model) “这需要规范、开发、验证和演化的基本过程活动,并将它们表示为独立的过程阶段,如需求规范、软件设计、实现、测试等。” 1970年Winston Royce提出了著名的"瀑布模型",直到80年代早期,它一直是唯一被广泛采用的软件开发模型。 组成:瀑布模型将软件生命周期划分为制定计划、需求分析、软件设...

(1)waterfall model: plan-driven. 流水式开发,顾名思义,从requirements按顺序一直到maintenance是一轮,一轮接一轮直到完成。一轮中的阶段非常明确。比如过了design阶段就不能再翻回去,要继续implementation阶段。 (2)incremental development: specification, development and validation are interleaved(交错的,交织的)....
This paper describes the Software-Engineering Process Simulation (SEPS) model developed at JPL. SEPS is a dynamic simulation model of the software project-development process. It uses the feedback principles of system dynamics to simulate the dynamic interactions among various software life-cycle deve...
摘要: A descriptive process model of software re-engineering is presented. The overall structure of the process model is defined by the re-engineering approach. Three re-engineering approaches are described: lump sum, incremental, and evolutionary. The focus is on the breadth of possible tasks...
SPR results in a repository of managed process descriptions and a plan for disciplined software process management. In this article, we derive principles for SPR, use these principles to propose a model for re-engineering legacy process descriptions, and present an industrial case study to ...
