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.
