Modern telecom operators will have to change their business approach, organization models, products development and services development, customer approach and many other important issues if they want to be competitive on the telecommunication markets in the following years and decades. They will have key roles in this period named the Industry 4.0 era. There are many different models of analysis for telecom operators, but they all have a partial approach to analysis and none of them gives a complete picture of the analysis of telecom operators. The Comprehensive Techno-Economic (CTE) model for the analysis of telecom operator potentials is a new and original model for analysis. It will significantly help telecom operators in their transformation processes. This model will enable a quick and easy analysis of the potential of telecom operators, but also of individual parts of it, regardless of other parts of the company. Despite the fact that the model is easy to define the input data and that it is fast in applying the analysis, it gives reliable and mathematically defined results of the potential of telecom operators or independent assessment of their segments. The main advantages of this model are simplicity, speed of telecom analysis, reliability of results and its modularity, i.e., independent evaluation of individual segments. This model is necessary for telecom operators to achieve fast and reliable potential assessment, analysis, modeling and the easier adaptation of new products and services. This is a unique model with a scientific background and theoretical settings and it enables practical application on the telecommunications market.
