The process of digital transformation in the Russian Federation started long ago, but it is not evident in its scale, although the strategic development of industrial companies shows the transformation of their traditional lines of business under the influence of competition intensified by the introduction of high digital technologies. According to statistics, one in three companies in Russia uses a digital transformation strategy. Analysing the choice of an organization's development strategy largely depends on the level of management's readiness to optimize business processes, change the organizational structure, and transform the management decision-making process. To date, there is no unified toolkit for assessing companies' readiness for digital transformation, so parameters have been developed to assess the readiness of representatives of Russian companies. The article identifies criteria for assessing companies' readiness for digital transformation, including such parameters as digital transformation status, companies' readiness to use data, the level of developing digital infrastructure, efficiency from customer experience management, digital collaboration, employee competencies, and Russian companies' budget for digital transformation. The authors conducted a study to identify the level of the digital readiness of various Russian companies, including oil and gas companies, which showed that most organizations have an average level of readiness for digital transformation, as the digital infrastructure does not fully meet business needs, management is based on superficial data analytics, and the most organizations generally not include digitization in their overall development strategy to date.
