The ICT Cluster is a Bulgarian organization with 280 member ICT SMEs and universities that aims to increase competitiveness through promoting clusters. Industry 4.0 influences all sectors of the economy. SMEs face challenges implementing smart manufacturing like lack of digital strategies, skills, funding, R&D access, and state support. Most SMEs plan to implement novel technologies and HR management for smart manufacturing in the future. Clusters help SMEs with industrial transformation through mapping needs, matching partners, transferring knowledge, and bridging organizations.
