In 2007, Geoff Mulgan et al. identified entry points for action in a report titled Social Innovation: What It Is, Why It Matters and How It Can Be Accelerated; the catalog of requirements for success featured leadership and structures suited for innovation; finance focused on innovation; policy frameworks that encourage innovation; dedicated social innovation accelerators; national and cross-national innovation pools; and research to enhance learning.

Additional items, "hot topics" as this query terms them, relate to participatory techniques and specific training; citizen involvement and buy-in; systems of cooperation between business actors, local public entities, and civil society and nongovernmental organizations; the recording of good practice from model cases; and new forms of evaluation that give greater attention to social impacts.

Many thanks Olivier.
