Production in networks and clusters is gaining more and more importance in theory and practice. Micro enterprises and small and medium-sized enterprises possess a high potential of networking. Innovative concepts, like concepts of Competence-cell-based Networks and Clusters, can exploit this potential. For this a three-layer procedural model of the production network formation, an upward compatible cluster concept including technical-organisational and spatial-infrastructural aspects as well as factors for success for networks and clusters are presented. Future strategies for a rethinking about these points in enterprises of production and service are pointed out as thesis.
