At present, the focus of discussions on digital transformation has shifted from issues of its necessity to problems of assessing a company's readiness for digital transformation. The specificity of digital transformation in Russia requires new criteria of readiness and prioritization of existing criteria. This study explores a combination of factors (prerequisites) that determine the readiness of Russian companies for digital transformation. Our hypothesis is that it is possible to systematize and formalize these prerequisites, which can be presented as a framework for assessing readiness. The purpose of the study is to design such a framework that takes into account not only the current state of the company, but also its previous development. The paper formulates the requirements for the readiness assessment system in the form of a framework. It also proposes a method of desing a framework with these requirements. The method combines analysis of practical cases and theoretical study of modern concepts and best management practices. As a result of applying the proposed method a framework for a company's readiness for digital transformation assessment (DTRA) is created. The DTRA framework includes criteria and characteristics of readiness grouped into domains. It is intended for a qualitative evaluation of readiness and for understanding obstacles to success of the digital transformation.
