Evaluating an Embedded Software Reference Architecture

In this paper, we discuss experiences gained during evaluation of the maintainability of a reference architecture in use at Océ, one of the world’s leading copier manufacturers. The evaluation is conducted using an approach based on SEI’s Software Architecture Analysis Method (SAAM). The paper proposes a variant of SAAM that helps to reduce the organisational impact of architecture evaluations. Second, we analyse the implications of evaluating reference architectures as opposed to single-product architectures. Furthermore, we share our experience of conducting the evaluation, draw lessons for practitioners, and propose new research topics.
