A Portfolio-Driven Development Model and Its Management Method of Agile Product Line Engineering Applied to Automotive Software Development

摘要

In recent automotive systems development, realizing both variability and agility is the key competitiveness to meet the diverse requirements in global markets and rapidly increasing intelligent functions. This article proposes a portfolio-driven development method and its management method of APLE (Agile Product Line Engineering). The proposed method is intended to manage agile evolution of multiple product lines while increasing variability of products. To establish a portfolio management of development resources, it is necessary for an organization to manage multiple product lines on APLE in an entire development. We propose a portfolio-driven development method of three layers on APLE and its management method based on a concept of portfolio management life cycle. We applied the proposed management model and method to the multiple product lines of automotive software systems, and demonstrated an improvement of manageability with better predictability of both productivity and development size. This article contributes to provide an entire development management method for APLE, and its practical experience in the automotive multiple product lines.
