This article presents a comparison between different theoretical frameworks proposed by different authors in the last 5 years, finally presenting a proposal based on different aspects or strategic axes that, based on the analysis developed, the authors of the present sustain as main for the organizations take into account in the internal and external processes of Industry 4.0 to achieve a company with a higher level of competitiveness.

This article compiles and consolidates a search for reference frameworks from sources such as university repositories, reports from public and private entities, technology journals, among other reliable sources that strengthen and offer value to the research conducted. In order to choose the most decisive frameworks for the construction of the article, three (3) inclusion criteria and five (5) exclusion criteria were proposed, which helped the authors to make a more specific and effective choice process, thus obtaining nine (9) reference frameworks that met the criteria proposed. In this way, the strengths and weaknesses of each chosen framework were identified, which led to the analysis of the strategic axes determining the most frequent that the authors of these raised within their proposal, allowing the construction of a proposal based on the most relevant axes considered to identify the opportunities and capabilities of digital transformation in organizations of any sector, size and regardless of whether or not they belong to digital business, reaching as a result four (4) strategic axes focused on the customer. Thus framing the importance that digital transformation represents for organizations seeking to stay in the market for a long time in a profitable way and likewise the benefits that this transformation brings when applied properly in organizations. Finally, the conclusions that the authors obtained from the research are presented and some ways to continue the research in future works are proposed, taking into account that the digital transformation is constantly updated with respect to today's volatile market.
