소프트웨어 과업변경에 따른 대가지급 방안

Abstract

One of the biggest factors of software projects failure is that we can’t understand, analyze, document, manage, and control the complex requirements from various stakeholders. In other words, incorrect requirements and specifications have created many problems of unclear business purpose and scope, bad business forecasting, and the problem of low quality and it is possible to cause problems of the development cost. In order to solve these problems, a clear specification of requirements should be made. We suggest cost estimation method that utilizes successful bid difference challenges of SW business, which was determined by using a clear specification of such scope changes. First, the general business environment of SW scope modification and operational status are analyzed. Based on the results of this analysis, the key success factors of scope change management tasks and prerequisite information is derived. Finally, we suggest the cost estimation method taking advantage of the difference between successful paid bids.
