On-Demand Generation of Views to Support Online Evolution of Software Product Lines
This presentation was created for the SATURN conference series and does not necessarily reflect the positions and views of the Software Engineering Institute.
It is difficult to achieve assured conformance between
architecture and code. We lacked proper architecture descriptions in the
context of the evolution of an industrial software product line of logistic
systems. As a result, a lack of explicit architecture documentation about the
deployed products led to ad hoc update practices, which were error prone and
resulted in unnecessary and undesirable shutdowns. To tackle these problems, we
have codified the architecture knowledge required for evolving products in a
viewpoint. Based on this viewpoint, we developed a supporting tool that allows
generating on-demand architecture models. These models guide maintainers by
listing the concrete tasks they need to perform when upgrading a system and by
showing inconsistencies when they fail to do so. The evaluation of 68 updates
of industrial logistic systems demonstrates a significant improvement in the
quality of system updates with respect to the correct execution of updates and a
reduced interruption of services.
