Requirements Metrics for Requirements Statements Stored in Database

摘要

In a software development project, a requirements document, either a hard copy or stored in a database, summarizes the results of requirements analysis and becomes the basis for subsequent software development. In many cases, the quality of the requirements statements dictates the success of software development. The need for determining the quality of requirements statements is acute when the target applications are large, complicated, and mission critical. The purpose of this research is to (1) summarize our previous research on the quality indicators that indicate the quality of requirements statements in a requirements document and (2) report our current research to expand the previous quality indicators to evaluate the quality of requirements statements stored in a database. A suite of complexity metrics of requirements statements is proposed as quality indicators and is developed based upon research of noun phrase (NP) chunks.
