基于用例点的软件项目工作量估算

Software Project Effort Estimation Based on Use Case Points

目前软件估算在软件开发过程中的应用相当普遍而且重要,而以用例模型为基础的用例点估算方法具有容易操作性、实用性、可靠性好等特点。同时对于使用用例估算,存在着不同的方法和途径来估计工作量。文中主要研究软件估算方法中的用例点估算方法,详细描述其在项目工作量估算过程中的流程和方法以及相对应的估算公式。最后通过一个简单的案例展示项目工作量的估算过程,能更好地说明在软件项目工作量估算中用例点估算方法的方便及其可行之处,从而为项目计划和管理提供更好的支持。

Software estimation is quite common and important in the software development process. Use case point estimation method based on the use case model has characteristics of easy maneuverability, practicality, reliability. And there exists different ways and means to estimate the workload with use case estimation. It researches the use case point methods in software estimation methods and describes the processes and methods and the corresponding estimation formulas in the software project effort estimation in detail. Finally,through a simple case demonstrate the project effort estimation process that can better describe the convenience and feasibility with use case point es- timation method in the software project effort estimation,providing the better support for the project planning and management.
