Abstract

We present a case study that aimsat quantitative assessment of the impact of requirements changes,and quantitative estimation of costs of the development activitiesthat must be carried out to accomplish those changes. Our approachis based on enhanced traceability and an integrated view of theprocess and product models. The elements in the process and productmodels are quantitatively characterised through proper measurement,thus achieving a sound basis for different kinds of sophisticatedanalysis concerning the impact of requirements changes and theircosts. We present the results of the application of modelingand measurement to an industrial project dealing with real-timesoftware development. The ability to predict the impact of changesin requirements and the cost of related activities is shown.
