Architectural viewpoints for global software development
(IEEE, 2011) Yıldız, Buğra M.; Tekinerdoğan, Bekir
Global Software Development (GSD) can be considered as the coordinated activity of software development that is not localized and central but geographically distributed. Designing an appropriate software architecture of a GSD system is important to meet the requirements for the communication, coordination and control of the distributed GSD teams. A common practice in software architecture design is to apply architectural views to model the design decisions for the various stakeholder concerns. Unfortunately, existing architectural viewpoint approaches are general-purpose and not directly dedicated towards GSD projects. In this paper we propose six architectural viewpoints that have been specifically defined to model GSD systems. The architectural viewpoints are based on a meta-model that has been derived after a thorough domain analysis of the GSD literature. © 2011 IEEE.

Defining architectural viewpoints for quality concerns
(Springer, Berlin, Heidelberg, 2011) Tekinerdoğan, Bedir; Sözer H.
A common practice in software architecture design is to apply architectural views to model the design decisions for the various stakeholder concerns. When dealing with quality concerns, however, it is more difficult to address these explicitly in the architectural views. This is because quality concerns do not easily match the architectural elements that seem to be primarily functional in nature. As a result, the communication and analysis of these quality concerns becomes more problematic in practice. We introduce a general and practical approach for supporting architects to model quality concerns by extending the architectural viewpoints of the so-called V&B approach. We illustrate the approach for defining recoverability and adaptability viewpoints for an open source software architecture. © 2011 Springer-Verlag.

Safety perspective for supporting architectural design of safety-critical systems
(Springer, Cham, 2014) Gürbüz, Havva Gülay; Tekinerdogan, Bedir; Er, Nagehan Pala
Various software architecture viewpoint approaches have been introduced to model the architecture views for stakeholder concerns. To address quality concerns in software architecture views, an important approach is to define architectural perspectives that include a collection of activities, tactics and guidelines that require consideration across a number of the architectural views. Several architectural perspectives have been defined for selected quality concerns. In this paper we propose the Safety Perspective that is dedicated to ensure that the safety concern is properly addressed in the architecture views. The proposed safety perspective can assist the system and software architects in designing, analyzing and communicating the decisions regarding safety concerns. We illustrate the safety perspective for a real industrial case study and discuss the lessons learned. © 2014 Springer International Publishing Switzerland.

Software language engineering of architectural viewpoints
(Springer, Berlin, Heidelberg, 2011) Demirli, Elif; Tekinerdoğan, Bedir
A common practice in software architecture design is to apply architectural views to design software architecture for the various stakeholder concerns. Architectural views are usually developed based on architectural viewpoints which define the conventions for constructing, interpreting and analyzing views. So far most architectural viewpoints seem to have been primarily used either to support the communication among stakeholders, or at the best to provide a blueprint for the detailed design. In this paper we provide a software language engineering approach to define viewpoints as domain specific languages. This enhances the formal precision of architectural viewpoints and leads to executable views that can be interpreted and analyzed by tools. We illustrate our approach for defining domain specific languages for the viewpoints of the Views and Beyond approach. © 2011 Springer-Verlag.

Variability viewpoint for introducing variability in software architecture viewpoints
(ACM, 2012) Tekinerdogan, Bedir; Sözer H.
Variability is the ability of a software system to be changed for a specific context, in a preplanned manner. As such, to facilitate the instantiation of a software architecture the variability concern needs to be explicitly addressed. Usually, architectural concerns are represented using architecture views that are derived from the corresponding architecture viewpoints. Different software architecture viewpoints have been introduced to support the modeling, understanding, communication and analysis of the software architecture for different stakeholders. Regarding variability we can observe that this has been mainly addressed in separate variability modeling approaches. In this paper we first provide a short overview of the approaches for dealing with variability at the architecture design level and then introduce the variability viewpoint. The variability viewpoint addresses the concerns for variability and can be used to introduce variability in software architecture viewpoints. Copyright 2012 ACM.
