A Concurrent Feedback Development Method and Its Application to Automotive Software Development
Kengo Hayashi, Mikio Aoyama, Keiji Kobata · 2015
This paper proposes an approach to concurrent feedback development method in the software development of automotive systems. The automotive software is increasing its size and complexity. Therefore, it has become more difficult to ensure quality. At the same time, automobile manufacturers demand to shorten the development time. Conventionally, we developed the software in the two phases of "prototype development for developing requirements significations" and "product software development based on the requirements specifications". In this article, we propose the concurrent feedback development method using the prototype in the specification development. The proposed concurrent feedback loop model consists of three patterns of feedback loop to evolve the product concurrently. We demonstrated a reduction of the development time and improved the internal quality of the product in our automotive system development.
