The GESSI research group of the Software Department at the UPC conducts research in many fields of software engineering, with particular emphasis on procurement and implementation of COTS components, requirements engineering, construction of quality models for software domains and software process modelling and enactment; also software certification is a target for the near future. We are also focusing in some particular kinds of software components and packages, remarkably ERP systems and container libraries.

    Successful software evolution heavily depends on the selection of the right features to be included in the next release. Such selection is difficult, and companies often report bad experiences about user acceptance. To ...
  • Using contextual goal models for constructing situational methods 

    Ralyté, Jolita; Franch Gutiérrez, Javier (Springer, 2018)
    Conference report
    Open Access
    Situation and intention are two fundamental notions in situational method engineering (SME). They are used to assess the context of an ISD project and to specify method requirements in this context. They also allow defining ...
