The benefits of agile frameworks applied to small projects have aroused interest in the large-scale software industry. However, applying them in scaled environments has meant facing multiple challenges, including communication, coordination, and cooperation. Scaled frameworks emerge in response to these challenges, describing the implementation guides to achieve the agile large-scale transformation. However, a lack of conceptual clarity regarding the elements prescribed by these frameworks was identified in the literature. This article introduces the Scaled Agile Model reference model, which integrates the experience reported in the literature and the fundamental attributes of scaled agile frameworks: SAFe, LeSS, Nexus, and DAD. A protocol was followed for the harmonization of multiple models, which allowed integrating and obtaining a reference model from the results of the harmonization of frameworks and the literature found. Additionally, SAM was evaluated for clarity, suitably, and completeness through a focus group. Thus, the proposed reference model defines sixteen roles, three levels of scale, and 34 practices grouped into 8 categories. The results suggest a good acceptance by the experts who evaluated the proposal. Likewise, the proposed model aims to be of great practical benefit for companies that want to scale, companies that are scaling, or companies that have already scaled and want to evaluate their implementation.

Keywords : DAD; large scale agile development (LSAD); LeSS; Nexus; SAFe; scaling agile; software global development (SGD)..
