      It is well known that requirements changes in a later phase of software developments is a major source of software defects and costs. Thus, the need of techniques to control or reduce the amount of changes during software ...
    • Goal-driven adaptation of service-based systems from runtime monitoring data 

      Franch Gutiérrez, Javier; Grünbacher, Paul; Oriol Hilari, Marc; Burgstaller, Benedikt; Dhungana, Deepak; López Cuesta, Lidia; Marco Gómez, Jordi; Pimentel, João Henrique (Institute of Electrical and Electronics Engineers (IEEE), 2011)
      Conference report
      Open Access
      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 of their component ...
    • Measuring architectural adaptability in i* models 

      Pimentel, João Henrique; Franch Gutiérrez, Javier; Castro, Jaelson (2011)
      Conference report
      Open Access
      Developing adaptable systems is still a big challenge in software engineering. Different reference architectures and systematic approaches have been proposed to address this challenge. Several of these approaches are based ...
    • Specification of failure-handling requirements as policy rules on self-adaptive systems 

      Pimentel, João Henrique; Castro, Jaelson; Franch Gutiérrez, Javier (2012)
      Conference report
      Open Access
      Most adaptive systems have compensation mechanisms for recovering from or preventing failures. However, sometimes a compensation is not essential. Hence, diagnosing and compensating each and every one of their failures ...
    • Towards anticipating requirements changes through studies of the future 

      Pimentel, João Henrique; Castro, Jaelson; Perelli, Hermano; Santos, Emanuel; Franch Gutiérrez, Javier (Institute of Electrical and Electronics Engineers (IEEE), 2011)
      Conference report
      Open Access
      Whilst it is considered a good practice to focus Requirements Engineering on current stakeholder needs, the high costs implied by requirements changes and the emergence of the Autonomic Computing paradigm raised the need ...
