Managing Software Interfaces of On-Board Automotive Controllers

This article provides a birds-eye view of the enormous upheaval involved in enhancing reuse across a product line. The classic approach originally espoused by David Parnas-separation of concerns-is an important driver, but the big take-away is that even when a team of experts collaborates on architectural refactoring, its a slow, incremental process. There is no easy road to reuse.

Evaluation of the Use of Quality Attribute Scenarios in a Plug-In Hybrid Electric Vehicle Controls System - Industrial Case Study

This paper presents a study in using quality attribute scenarios to evaluate and improve the software architecture of a control system that plans and affects energy use on a plug-in hybrid electric vehicle. The study confirmed for us the value of the quality attribute workshop approach in an industrial, automotive controls setting. This experience has helped us to understand how we might improve the effectiveness of this type of architectural design method within our companys technology development environment.
