An Empirical Evaluation of the PLUSS Toolkit
Magnus Eriksson, Henrik Morast, Jürgen Börstler, Kjell Borg · 2006
The PLUSS approach (Product Line Use case modeling for Systems and Software engineering) is a domain modeling method tailored towards the development of long lived software intensive systems, for example defense systems. The goal of the PLUSS approach is to provide means to maintain a common and complete use case model for a whole family of systems, and to provide a good overview of all variants within such a family. In this paper, we describe how the commercial requirements management tool Telelogic DOORS and the UML modeling tool IBM-Rational Rose can be extended and used for managing system family models in accordance with the PLUSS approach. We refer to these extensions as the PLUSS toolkit. An empirical study is presented where the PLUSS toolkit is applied and evaluated in the target domain. Results indicate that the toolkit allow developers to work effectively. Some minor shortcomings of the toolkit were however identified and we therefore propose improvements to increase its efficiency.
