Strategic choice of implementing IT function in multidisciplinary companies

The article focuses on the analysis and identification of possible factors that influence the choice of  an IT function implementation model in multidisciplinary companies (MNCs). Today, there are several IT function management models available for managers of multidisciplinary organisations. However, the conditions for choosing these models, as well as the practical ways to implement them, depending on the chosen model, have not been widely discussed among the scientific community.The article aims to provide a comprehensive analysis of current models and methods of managing IT functions within multidisciplinary organisations, as well as the factors that influence their choice in these companies.A behavioural analysis of the literature on the research topic has been carried out, which has led to the identification the main models for IT function management in multidisciplinary companies. The factors influencing the choice of a particular model of interaction between MNC businesses and IT functions have been identified, as well as practical ways to manage IT functions. From a practical perspective, the business community is provided with a description of potential options for selecting and managing models of IT functions, as well as the criteria for choosing them. From a scientific point of view, it contributes to the enrichment of research on the management of affiliated IT companies. To date, there has been no comprehensive classification of effective management models for these companies, nor has there been an assessment of the impact of a particular model on the overall effectiveness of a company, depending on how the IT functions are managed.  The scientific community has also not provided practical solutions for implementing a centralised or decentralised model for managing IT functions.
