对项目成本的准确估算是进行再工程项目的必要前提。现有的系统通常是重新设计的，因为重新设计它们比重新开发或更换它们更便宜。然而，要做出这个决定，管理层必须知道再造的成本。本文描述了一个八步工具支持的过程，用于计算重新设计现有系统所需的时间和成本。这个过程来自于作者20年来评估再工程项目的经验，并通过几个真实的现场实验进行了验证，在这些实验中，这个过程得到了改进和校准
Accurate estimation of project costs is an essential prerequisite to making a reengineering project. Existing systems are usually reengineered because it is cheaper to reengineer them than to redevelop or to replace them. However, to make this decision, management must know what the reengineering will cost. This contribution describes an eight step tool supported process for calculating the time and the costs required to reengineer an existing system. The process is derived from the author's 20 year experience in estimating reengineering projects and has been validated by several real life field experiments in which it has been refined and calibrated
