Service system is gaining momentum in providing flexible and dynamic solutions for integrated business solutions. Much of this power comes from the global standards imposed on services and synergy through integration. In order to manage service system resources taking into the vast volume of services, knowledge is the key. Existing knowledge concerning services was originally restricted to service providers and a special range of users who are knowledgeable about the services being provided. Therefore, efficient knowledge sharing will be required. The research presented in this paper takes the leverages of service systems and couples the automated knowledge management techniques towards a framework of service oriented knowledge management. In particular, services developed under this research are categorized as system services. The paper explores some generic situations on how system services may interact with external business services in forming application solutions. Under such an approach, dynamic on-demand solutions for an application field can be effectively developed.
