Function Point Extraction Method from Goal and Scenario Based Requirements Text

Efficient processing of software requirements expressed in natural language is still and active area of research in systems development. Function Point is widely used as a basis to estimate software development cost and schedule. This paper discusses a method for extracting function point from requirements text gathered using the goal and scenario based requirements elicitation technique. The proposed method aims to establish and maintain traceability between function point and requirements text. Text based function point extraction guidance rules have been developed. The proposed method-ology has been applied to Order Processing System development.
