This paper aims at describing a proposed Performance Indicators (PIs) Toolset, which has been developed to provide useful methodologies and tools to enterprises, especially Virtual Manufacturing Enterprises (VMEs), in order to support the management and evaluation of their service systems. Particularly, the identified PI Toolset helps VMEs to understand how well they are performing and contributing to their strategic goals and objectives.Indeed, determining which activities should be monitored, controlled and measured through proper PIs is essential for a VME. In this context the proposed PI Toolset helps to select the significant activities, to manage governance processes, and to support the design and implement the specific PIs related to the precise use case objectives. Finally, the proposed Toolset defined a set of PIs that can be used to evaluate business processes related to governance issues.
