Modern manufacturing and business based on product service systems require software platforms capable of supporting offerings over their lifecycle thus securing long term customer value. Also a function to get and manage feedback from end users, customers and manufacturing is essential for design to build in functionalities and features that best enable efficient use and maintenance. The aim is to integrate the Product Life-Cycle Management (PLM) and Service Life-Cycle Management (SLM) concepts resulting in a coherent and collaborative Product-Service design and manufacturing engineering platform. The concept requirements were collected from four real world use cases and refined and combined to create final set of requirements. In this paper we present the facilitated requirement collection process and the final requirements in relation to engineering collaboration and product-service system characteristics.
