The social innovation streams have furthermore been embedded into and examined as regards the influence of field/context conditions on actor involvement in the innovation and the transformative capacity of the stream (profoundness, scope of change occurring, etc.) overall. More broadly speaking, however, the research of ITSSOIN was also a continuation of work conducted previously in another project funded by the European Commission and called TEPSIE. This chapter aims to present highlights from the qualitative case work and discuss and compare them to each other regarding the relevance of those organisational traits which appear to have been influential on the development of the social innovation streams in each of the analysed fields. It highlights some of the learnings that emerged from the cases beyond the main lines of inquiry and in relation to our supposition of a particularly high social innovativeness in third sector organisations.
