The European Software Institute (ESI) is a division of Tecnalia with its headquarters in Spain.
One of the early "products" of the institute was a methodology for analyzing and improving processes in software-producing organisations which then became a standard ISO/IEC 15504 with the popular name "SPICE". This standard was the European "answer" to the Capability Maturity Model Integration (CMMI) methodology having been developed at the Software Engineering Institute at Carnegie Mellon University, Pittsburgh, Pennsylvania, US, which today is an institute being in "co-optition" with ESI.
