Recent research shows that manufacturers' contribution to sustainable development can be improved by adopting a product service system (PSS). It is argued in this paper that such non-traditional business strategy is a crucial decision to the enterprise. Metrics need to be identified at different levels: industry, enterprise, and product. The objective of this research is to identify PSS metrics for agriculture industry. PESTEL analysis is carried out to determine these metrics. A case study of a grain spreader is used to derive the appropriate metrics. Decision model is developed and its can be implemented by the PSS partners.
