Every Action Group has its own policy towards accepting new partners. All Action Groups are proactive in assembling and maintaining a diversified group of partners, therewith having a comprehensive coverage of the innovation value chain. Several Action Groups favour a focused work plan in which they have assigned specific partners to specific tasks. Other Action Groups favour a more open policy because they wish to collect a wide range of voices. All Action Groups are in principle open for solicitations of organizations a/o companies that wish to contribute. However, it is up to the individual Action Group to decide upon acceptance of solicitations (as is often written down in their internal charters of operations). The Secretariat is available to inform and guide such solicitations.
