Modeling a project scope using a case-based reasoning approach

Abstract

The availability of a good, complete scope definition in the early stages of a project is widely recognized by industry practitioners as a key factor for overall project success. This paper presents a Project Scope Modeling Methodology for computerized decision support during the definition of a new project scope. The methodology is based on the effective reutilization of historical project scope definitions through the application of Case Based Reasoning (CBR), an Artificial Intelligence approach. In CBR, the previous experiences are reused in solving new situations reducing the complexities of modeling reasoning processes. By using CBR, the scope modeling methodology helps to find and reuse the most relevant historical information, allowing to easily consult and combine information from multiple scope definitions in a computerized environment. The resulting scope definitions are ready to serve as input information for different planning purposes. The application for conceptual cost estimating is discussed.
