## 2 Theoretical Framework
### Digital Transformation: Best Practices  
The DT process comprises different stages, starting with a definition of the strategic vision, followed by an understanding of the organization of DT capabilities and the definition of collaborators' and end-users' experiences, and ending with the technological definition and creation of roadmaps [59].  
Regarding the literature on best practices to be adopted in the digital transition, in the work of [PERSON] and [PERSON] [26], the authors carry out a systematic literature review (SLR) to establish a set of eight main recommendations to be taken into account in digital transition processes: digital strategy, business agility, innovation and ambidexterity, modern organization structure, digital culture, top management support, adequate information technology (IT) infrastructure, and digital skills. Concerning the first guideline, the addition of technology should not occur per se, but the strategic need for its adoption should be found while maintaining alignment between the technological infrastructure and the core business. Also on this point, the authors discuss the importance of defining visions, creating roadmaps (maps that define goals and objectives), and promoting continuous evaluations of digital transition processes. Regarding the second point, it is important to ensure the adoption of agile methodologies and promote empowerment of the work team. Concerning the scraping the study's third recommendation, partnerships with research institutions should also be considered. In terms of structure (fourth guideline), this should be composed of interdisciplinary teams. At the penultimate guideline level, it is important to guarantee an adequate infrastructure, since it is the pillar of the digital transition, and, at an operational level, it is important to have tools such as ERP. Support for new technologies, such as the cloud or IoT, must be ensured, never neglecting the cybersecurity aspect. Concerning the last guideline proposed, recruiting people with the right skills and investing in current team training arise as best practices.  
Culture and strategy have been highlighted as important in gaining a competitive advantage regarding digital transformation [60]. This same work [60] also emphasizes the role that roadmaps should play in this transition. Agility also shows a positive relationship with the success of the digital transition, making it possible to conclude that high levels of agility lead to high levels of success in the transition to the digital paradigm. [PERSON] et al. [27] investigated the practices to be followed to enter the I4.0 paradigm. In this work, strategy once again plays a key role, as does the creation of roadmaps. Improving work teams' competencies is also highlighted in this study as a relevant practice. This study also emphasizes the role of lean features in the digital transition, with the principles of this philosophy being predecessors to the adoption of emerging technologies. The perception of what benefits can be extracted from the adoption of technology is also underlined in this work. Approaches such as research partnerships, investment in research and development projects, and collaboration with specialists are also listed as enablers of the digital transition.  
In sum, despite having many benefits and great potential, barriers can hinder DT. In this sense, best practices can facilitate it, reducing the relative weight that barriers can have in adopting this technology. Figure 3 summarizes the importance of the study and clarifies the importance of best practices/recommendations in the DT process.
