什么是挣值管理(Earned Value Management)? 释义

挣值管理(Earned Value Management)是一个项目管理和衡量的综合技术,它综合了

  • 技术性能要求,
  • 带有明细进度安排的资源计划,
  • 并充分考虑项目风险。

换句话说,挣值管理就是将资源计划与进度要求、技术成本以及项目风险结合起来考虑的一项管理技术。 据此,所有的工作都经过计划、预算以及按照计划成本(Planned Value)递增来安排进度,从而形成一个以成本和进度为尺度的量度基准。


挣值管理的目的

挣值管理系统有两个主要目的:

  1. 鼓励项目承包人有效运用企业内部成本和进度管理控制系统; 同时,
  2. 允许客户依靠这些系统提供的实时数据,去决定产品导向的合同执行状态。

在执行一份合同中运用EVM的主要目的是:

  • 鼓励项目承包人有效运用企业内部技术、成本和进度管理控制系统;
  • 允许客户依靠这些系统提供的实时数据,进行更好的项目管理;
  • 反过来这些数据又能够用来决定产品导向的合同执行状态;
  • 根据趋势预测项目未来绩效表现。
  • 此外,EVM帮助企业制定更为有效的管理决定,减少项目负面影响。

挣值管理的优点

EVM为项目管理提供了具体目标——计划工作量。 在挣值管理过程中,项目管理团队能够对实际工作量与计划工作量进行比较。 据此,所有的工作都经过计划、预算以及按照计划成本(Planned Value)递增来安排进度,从而形成一个以成本和进度为尺度的量度基准。
