A multiple product line development method based on variability structure analysis
Kengo Hayashi, Mikio Aoyama · 2018
This article proposes a multiple product line development method based on variability structure analysis. In product line development, the problem area is divided into the domain engineering and application engineering for delivering diverse products. Now, the development of automotive software requires to meet both agility and extreme diversity, which is a big challenge. We developed a structural analysis method of variability for multiple product lines using an extended model of OVM (Orthogonal Variability Model). Together with the variability analysis method, we propose an agile application development method to refine development items according to variability dependency based on the analysis, and develop them incrementally. We applied the proposed method to the development of the multiple product lines of automotive software systems, and demonstrated to reduce the volatility of the test efforts and usage of the test environment, and higher velocity and better manageability of the value stream.
