Software Reuse Evaluation based on Functional Similarity in COSMIC-FFP Size Components

Software reuse is often recommended for improving the productivity of the development process. However, recognizing opportunities for reuse remains a challenge. This work proposes a technique to identify opportunities for reuse based on the similarity between software functions. This technique, referred to here as “functional similarity”, is based on functional information collected by the COSMIC-FFP measurement method during the measurement of the software. The proposed approach is applied to a set of measurement case studies for which opportunities for functional reuse have been identified and quantified.
