Abstract
The widespread adoption of digital technology tied with the 4th industrial revolution means the complete reinvention of how business is done. Digital Twin (DT) technologies are now a key technology trend that is already being developed and commercialized to optimize numerous manufacturing processes. In this paper, and from an Information Systems (IS) discipline viewpoint, we take stock of the different technological visions of the DT in manufacturing. We leverage this summary as a stepping stone for discussing the DT's sociotechnical design implications by pointing how this approach is essential for the design of DT software that is specific to its environment and users and co-evolves with it. Furthermore, we present our vision for a DT-based Digital Platform that can support product design and life-cycle management while generating value through an ecosystem of twin-driven product-service systems. Lastly, we show how the Transformer 4.0 project will demonstrate the main principle of our vision by placing the DT of the power transformer with the dual role of virtual counterpart of the physical product and as the architectural framework for (i) managing and processing the historical data collected from the multiple working instances of DTs, and (ii) managing and integrating design information (models, specifications, design data, among others).

Abstract
The impact of digital technologies in manufacturing organizations has been felt for decades. Servitization processes themselves have developed from the traditional Product-Service Systems (PSS) toward new business models infused with digital technologies, paving the way to smart PSS. There is, however, a lack of understanding of how digital platforms (DP) can be leveraged for the offering of smart service offerings. In this paper, we highlight how the emergence of DP traces the evolution of PSS and highlight how a platform-based modular architecture can serve as the reference infrastructure for organizations to deliver smart and highly customized products and services. The architecture of the Transformer 4.0 platform is used to demonstrate how DP can serve as orchestrators for an ecosystem of digital twin-driven smart PSS.

Abstract
Many organizations find the emerging concept of the Digital Twin (DT) to be compelling as a potential means to reduce the time and cost to develop new products, support fielded products, and enable rapid innovation to respond to new market opportunities. However, realizing the full potential of a DT may require significant changes in the methods, processes, and tools for product development and support currently used by potential adopters in the organization. We introduce an approach for assessing the behaviors and capabilities of the DT and their relationships within the organization's sociotechnical system. We believe this approach can enable DT implementation outcomes better aligned with the organization's strategic goals and objectives, and help to clarify not only what the DT can do, but what it should do for the organization. The approach is explained using an illustrative case study example, which is based on interim progress of our ongoing research project.

Abstract
Risk assessment is a theme of large spectrum applied in different fields. In the context of Virtual / Collaborative Enterprises there are several risks whose assessment should be aware to avoid undesirable consequences either for entire networked or for a partner in particular. The objective of this work is centered on the creation of a framework / guidelines to serve as a basis for the creation of a better risk assessment model for Virtual / Collaborative Enterprises. This work analyzed the few models available in the literature and identified some gaps that were used to purpose complementary guidelines for the design and / or improve the future risk assessment models. The pointed guidelines covered three important topics: risk factors; assessment methods; and the impact in different life cycle phases of a Virtual / Collaborative Enterprise. Considering the results of the work it is our conviction that there is space to improve the research in this field and a more robust and flexible risk assessment model should be developed.

Abstract
This paper presents a Cyber Physical System (CPS) laboratory based on Open Design, called Open Science Laboratory for Manufacturing (OSLab4Man), with educational and research purpose and the potential contribute and (direct and indirect) effects regarding the 17 Sustainable Development Goals (SDGs). A short introduction describing the 17 SDG, the education for sustainability role, and the relevance of the framed CPS. A literature review of CPS laboratories that are addressed to sustainability is presented. The OSLab4Man is describe in the educational purpose lens. Then, the contribute of the OSLab4Man as an education tool for sustainability regarding the 17 SDGs is reflected. Finally, the conclusions of this work and future works are highlighted.

Abstract
Purpose: The study purpose was to analyse the excellence and operational efficiency of Portuguese industrial companies through the measurement of lean practices implementation. Additionally, it intended to propose a new model to assess the lean production system. Design/methodology/approach: The research presents an in-depth lean literature review that served as a basis for the creation of a questionnaire. The survey was addressed to Portuguese industrial companies to obtain data about their lean implementation success. Collected data were analysed, resorting descriptive and exploratory statistics. A principal component analysis was applied to reduce the amount of data and define a new model that characterizes the lean practices adoption level. Some Chi-square tests were used to assess the independence of some variables. Findings: The results indicate that a significant percentage of organizations use lean practices within their activity. Concerning the lean implementation maturity, a plus side revealed by the study concerns the adoption of the teamwork, internal information shared principles, increase of process capability to produce conforming products, and reduction in set up times. On the other hand, responsibilities decentralization, more employees acting as team leaders, implementation of employees' suggestions, and interconnection with suppliers, are some of the principles that need to be given greater attention by the Portuguese industrial organizations. The key contribution consists of a new model for lean determinants based on three dimensions: work method, productive process elements, and work efficiency. Originality/value: The present research provides a new Lean determinants model that allows understanding the importance of the operational efficiency provided by a mature lean production system, being the key to the competitiveness in the global business market.
