Managing through-life information of products and services has become an important competitive means in customer-centric industries. The need for managing new types of product-service requirements for sustainability, traceability and performance have widened the traditional perspective of PLM information to integrate new issues, e.g. service information. In this study we examine how the diverse and through-life requirements information could better be integrated in product and business processes of customer-centric manufacturing. The study is based on a literature review and two case interviews. The objective is to elicit requirements information for Product-Service System (PSS). The study introduces the concepts of product-service system, and outlines through-life requirements in customer-centric business. PSS is a new concept for customer-centric business to improve the performance of sustainability, traceability, reusability and repeatability.
