Software project planning whole process management system and method

The invention relates to a software project planning whole-process management system and method. The method comprises the following steps: selecting a system model of a software project to be planned; determining each stage of the software project process and workload proportion recommendation of each stage based on the selected system model and the project related parameters; estimating the product scale of the software project to be planned; automatically estimating a total workload based on the estimated product scale; automatically determining the workload of each stage based on the estimated total workload and the workload proportion recommendation of each stage; and based on the workload, automatically calculating a project period and a task progress and determining a task work package. Scientific planning management and progress estimation are carried out on a software project, and it is guaranteed that the project is carried out in a controllable state. 本发明涉及一种软件项目策划全过程管理系统和方法，方法包括：选择待策划软件项目的体系模型；基于所选
