MQP emphasizes the context of a software model as a major factor of influence for the whole quality planning activity. In order to adjust a quality plan to project specific requirements, quality goals are derived from a characterization of that context. We achieve a differentiated description of quality goals by introducing structured goals and questions in combination with a defined quality model. Afterwards, metrics and indicators are identified for checking the fulfillment of the quality goals. The result of our approach consists of a context sensitive quality plan for software models. Conceptually, we combine a metamodel for formulating relevant contents, a process that serves as a guideline for defining quality plans, and a rule concept for packaging and reusing experience into an integrated framework. We show its feasibility by three case studies that include a quality plan for analysis models, design models, and test models, respectively. For that, we provide tool support for the definition and application of quality plans.}}, author = {{Voigt, Hendrik}}, title = {{{Kontextsensitive Qualitätsplanung von Softwaremodellen}}}, year = {{2009}}, } @phdthesis{7575, author = {{Schattkowsky, Tim}}, title = {{{Platform independent modeling of synthesizable software systems using UML 2}}}, year = {{2009}}, } @phdthesis{7577, author = {{Förster, Alexander}}, title = {{{Pattern based business process design and verification}}}, year = {{2009}}, } @phdthesis{7578, abstract = {{Enterprise Architecture (EA) has undergone many changes since the IT has found its way into the world of enterprises. The introduction of Service-Oriented Architecture (SOA) is such a change with major consequences. The introduction of an SOA increases the flexibility and thus the productivity of an enterprise architecture, but unfortunately also its complexity. This makes the transformation of an enterprise architecture to an SOA-like enterprise architecture to a challenging and risky task. To overcome the change- and complexity-related problems when introducing SOA, Enterprise Architecture Management (EAM) systems are required. The approach of this thesis suggests a method on how to establish Enterprise Architecture Management that is especially suited for an SOA introduction. This thesis suggests a variant of an EAM system that is especially suited for the introduction of an SOA. The presented method on creating such an EAM system includes guidance on how to define a meta model for Service-Oriented Enterprise Architecture (SOEA), which is harmonized with the respective enterprise architecture. The SOA introduction is especially supported by defining SOA quality criteria and corresponding metrics. Some metrics have to be ascertained by experts. Other metrics have their measuring points within the SOEA models (instances of the SOEA meta model) and their calculation is automatable. Creating and maintaining SOEA models as well as applying the automatable metrics are supported by an eclipse-based tool. As metrics only produce measures that are hard to interpret, indicators are introduced. They allow interpreting the measures concerning the quality criteria. With the help of this EAM system, the transformation of an enterprise to a service-oriented enterprise can be planned and the level of goal-achievement (SOA-conformance of the EA) can be monitored steadily. By this, the contribution of this work aims at the reduction of the risk when introducing an SOA.}}, author = {{Assmann, Martin}}, title = {{{Model-based evaluation of service-oriented enterprise architectures}}}, year = {{2009}}, } @inproceedings{8431, author = {{Mlynarski, Michael and Güldali, Baris and Späth, Melanie and Engels, Gregor}}, booktitle = {{MoDeVVa '09: Proceedings of the 6th International Workshop on Model-Driven Engineering, Verification and Validation}}, pages = {{1--10}}, publisher = {{ACM}}, title = {{{From Design Models to Test Models by Means of Test Ideas}}}, doi = {{http://doi.acm.org/10.1145/1656485.1656492}}, year = {{2009}}, } @inproceedings{8432, author = {{Engels, Gregor}}, booktitle = {{First European Workshop on Behaviour Modelling in Model Driven Architecture (BM-MDA)}}, pages = {{5}}, publisher = {{ACM Press (New York, NY, USA)}}, title = {{{Automatic Generation of Behavioral Code - too ambitious or even unwanted?}}}, year = {{2009}}, } @inproceedings{8433, author = {{Salger, Frank and Engels, Gregor and Hofmann, Alexander}}, booktitle = {{Proceedings of the ICSE Workshop on Software Quality (WoSQ 2009)}}, pages = {{15--21}}, title = {{{Inspection Effectiveness for Different Quality Attributes of Software Requirement Specifications - An Industrial Case Study}}}, year = {{2009}}, } @inproceedings{8434, abstract = {{The software specification acts as a bridge between customers, architects, software developers and testers.
