2012 Software engineering notes  
The workshop aimed at exploring current and emerging methods, languages, notations, technologies and tools to model, implement, and manage variability in the software architecture.  ...  Variability (the ability of a software system or software artifact to be adapted for use in a specific context) is reflected in and facilitated through the software architecture.  ...  We identified three challenges related to variability at runtime.

Xavier Franch, Paul Grunbacher, Marc Oriol, Benedikt Burgstaller, Deepak Dhungana, Lidia Lopez, Jordi Marco, Joao Pimentel
2011 2011 IEEE 35th Annual Computer Software and Applications Conference Workshops  
Service-based systems need to provide flexibility to adapt both to evolving requirements from multiple, often conflicting, ephemeral and unknown stakeholders, as well as to changes in the runtime behavior  ...  We present the MAESoS approach which uses i* diagrams to identify quality of service requirements over services. The alternatives are extracted and kept in a variability model.  ...  External variability addresses the variability of artifacts that is visible to customers (i.e., variations on requirements) while internal variability remains hidden from customers.  ...
