The E-SLP project fosters collaborative inter-institutional curriculum designs. The outcome of these collaborations can be SLPs built from scratch or as puzzles (collection of existing learning building blocks). One of the consequences of international collaborative design is that it introduces distinct working practices and therefore requires teams to set innovative processes. It also brings opportunities from each institution to exchange policies and triggers new consensus. Furthermore, it requires harmonisation of recognitions and accreditations, which in turns prompts innovatory agreements. In the long term, these innovations could conclude in a normalisation and generalisation of international and interuniversity programmes.
