A product-service system (PSS) is an integrated solution with tangible and intangible artifacts, and it should be developed as such. However, the different natures of PSS objects in relation to abstraction level and detail level may hinder an integrated approach for dealing with PSS development. Those obstacles are greater when the initial development phases are considered, where uncertainty and unpredictability are high. One solution that development teams usually use for dealing with such problems is the employment of models for representing the development objects. However, those models may not be properly interconnected, reducing the overall understanding of a PSS as a system. One solution for providing a more integrated perspective of development objects is the use of models that are instantiated based on a meta model. This work aims to propose a meta model capable of integrating the objects resulting from a PSS development (such as requirements, value proposition, concept, architecture, among others) in a logical level and allow the instantiation of multiple models that show different perspectives to support the initial phases of servitization, from the beginning of the development process up to the final PSS architecture. The methodological framework of this work is the design research methodology, combining methods such as systematic literature review, case research and focus group. The main result of this work is a meta model, which will be aligned with a servitization framework that is being developed by the Integrated Engineering Group (EI) under the grant number 2015/23094-6 (FAPESP) and with the conceptual layers of the Engineering Operating System (EOS). This meta model will be verified by means of a prototypical application and an application case study. (AU)
