Case study of the Architecture Business Cycle

I'm writing a paper with the working title "A Case Study of the Architecture Business Cycle for a Vehicle Software Architecture" together with a co-author.
We have tried to identify how the Architecture Business Cycle (ABC) looks like for the software architecture in a modern vehicle with software deployed to 30-70 electronic control units (ECUs) connected by a number of multiplexed buses, such as CAN, MOST and LIN.

The main results we present are the benefits the Electronic & Electric Systems Engineering (EESE) department at Volvo Car Corporation has gained from participating in identifying the ABC. Of course there are some benefits also from a research viewpoint as well, for example how well we thought the ABC model worked for such a case study.
The data comes from in-depth interviews performed with 20 persons working at the EESE department.
