Aufwandsschätzung von Software-Reengineering-Projekten

Abstract

Prediction of costs and duration of software reengineering projects Costs and duration of projects to reengineer existing software are much easier to predict than the respective figures for software development projects. Moreover, in reengineering projects costs, risks and duration are much smaller. This article presents a tool-based method to calculate the three most important reengineering project types: encapsulation projects, renovation projects, and conversion projects. The method comprises eight consecutive steps — starting from reengineering requirements and ending with risk assessments and adjustments. A set of well-known prediction methods are incorporated, among them COCOMO, component analysis, function point analysis, data point analysis, and object point analysis. The method lays particular focus on the size of the projected software as well as on its complexity and quality.
