摘　　要：软件成本控制是项目综合管理的核心和基础,是避免或最终根除软件危机的重要途径。针对软件成本控制的难点问题,文中运用控制图研究成本控制方法。首先,研究成本控制基础,包括成本控制流程、成本控制策略、成本控制阶段;然后,研究控制图理论,包括控制图结构、正态分布的"3σ"原则、控制界限、确定失控点的规则;最后,以某MIS软件已完成的15个模块为例进行实例研究,计算控制界限、编制控制图,并对结果进行分析。结果表明,控制图为成本控制提供科学的管理方法和技术支持,是实现软件项目管理目标的有效途径。Software cost control is the core and base of the project integrated management, and is the important way to avoid or ultimately eradicate the software crisis. For the difficult problems of software cost control, use control chart to research the cost control methods. First, study the basis of cost control,including cost control process, cost control strategy, cost control phase ;then, study the theory of con- trol chart,including control chart structure,＂ 3,y＂ principle of normal distribution, control limits, rules of determining the out of control points; finally, research for the example of MIS software has completed 15 modules, calculate the control limits, compile control chart and analyse the results. The results show that the control chart provides the scientific management methods and technical support for cost con- trol,and is the effective way and means to achieve the goal of software project management.
