Extractive SPL adoption applied into a small software company

Acople Tecnológico SAS is a Colombian enterprise specializing in software development whose products use devices for biometric facial and fingerprint recognition. The functional overlap of such products provides an opportunity for systematic reuse, which reduces software development and maintenance costs. In this paper we report our experiences, lessons learned and future work from applying concepts of software product line engineering to evolve three of its different software applications into a software product line. Based on our experience, we explain how we have tailored existing concepts of product line engineering, specifically how we have followed the process thus far, which includes the variability analysis that refers to the study of commonalities and variabilities among a set of software applications, the development of reusable software assets, and the derivation of individual products from the product line.
