Visualizing and Measuring Software Portfolio Architecture: A Flexibility Analysis
2014 (English)In: 16th International Dependency and Structure Modelling Conference, DSM 2014, 2014, 65-74 p.Conference paper (Refereed)
In this paper, we test a Design Structure Matrix (DSM) based method for visualizing and measuring software portfolio architectures, and use our measures to predict the costs of architectural change. Our data is drawn from a biopharmaceutical company, comprising 407 architectural components with 1,157 dependencies between them. We show that the architecture of this system can be classified as a "core-periphery" system, meaning it contains a single large dominant cluster of interconnected components (the "Core") representing 32% of the system. We find that the classification of software applications within this architecture, as being either Core or Peripheral, is a significant predictor of the costs of architectural change. In regression tests, we show that this measure has greater predictive power than prior measures of coupling used in the literature.
