**Maturity models** & **Contributions** & **Description** \\ \hline Complexity Management & It is based on the complexity management strategy which can “deal with complexity”, “reduce complexity”, “void complexity”, “price complexity”, “generate complexity”. & Maturity levels predict an evolution that includes 0 to 6, being (0) initial, without understanding complexity, (1) defined: complexity fields are defined, (2) qualitative: complexity is qualitatively evaluated, (3) quantitative: quantitative trajectories (KPI) are elaborated, (4) analyzed: complexity measures are defined and initialized; (6) harmonized: internal and external complexity are harmonized. & Organizational strategy directs plans and actions for the achievement of Industry 4.0, smart factory refers to automation in production, smart operation indicates the level of integration between the activities, smart products on products designed to favor new data-driven services support services added to the products and employees support the digital transformation. \\ \hline \hline Smart Manufacturing System & The authors propose a strategy of implementation with a readiness assessment, framework, roadmap and maturity model. They evaluate the level of maturity of the organization dimensions, which refers to the design of processes; information technology; synchronous aims to evaluate the instruments for monitoring indicators and information connectivity. & The levels can be initial (does not exist), managed (roadmap available), defined (value proposition and key resources defined), transformed (strategy divided into tasks) and detailed business model (the business model is transformed). \\ \hline C3M Maturity Model [41] & Designed for application in “case management” that defines how a complex situation is managed and how services respond to customer needs. The acronym C3M combines CM-Case Management with 3 aspects that the model aims to address: characterization of the model of maturity, benefits and risks. & The maturity model involves the dimensions Strategy, Processes, Technology, Organization and People. It considers that levels should measure capabilities, benefits and risks and can be as follows: Individualistic, supported, managed, standardized, transformative. \\ \hline Capability Maturity Model (CMM) and Capability Maturity Model Integration (CMM) [15; 16; 38; 39; 41; 44; 45] & CMM is one of the first maturity model initiatives and was built in 1986 by the Institute of Software Engineering to respond to management and monitoring demands. In 2006 the model also started to consider the integration between technology as Control Objectives for Information and Related Technologies (COBIT), Information Technology Infrastructure Library (ITIL), Project Management Institute (PMI), and International Organization for Standardization (ISO). \\ \hline IMPULS Industrie 4.0 Readiness Model, by VDMA, Rheinisch-Westfalische Technische Hochschule (RWTH) Aachen and IW Consult [3; 11; 37] & Presented by the German Engineering Federation (VDMA), Cologne Institute for Economic Research Consult GmbH (IW Technische Hochschule (RWTH) Aachen and IW Consult [3; 11; 37] & Organizational strategy directs plans and actions for the achievement of Industry 4.0, smart factory refers to automation in production, smart operation indicates the level of integration between the activities, smart products on products designed to favor new data-driven services, data-driven services support services added to the products and employees support the digital transformation. \\ \hline \hline \end{tabular}
