The article examines coordination models for cross-functional teams in the international telecommunications industry amid accelerated digital transformation and the active rollout of 5G technologies. The scholarly relevance of the topic is conditioned by the need to revisit managerial approaches to the delivery of B2B projects in an environment marked by the growing complexity of integration solutions and the insufficient adaptability of traditional organizational arrangements. The purpose of the study is centered on the development and theoretical substantiation of the “Architect-Integrator” model as an instrument for improving operational effectiveness.
The methodological foundation of the study was formed through a synthesis of the systemic analysis of industry materials produced by Gartner and Deloitte, supplemented by case studies of critical infrastructure projects implemented in the aviation, banking, and healthcare sectors. The analysis conducted showed that the introduction of relational coordination mechanisms contributes to a reduction in operating costs in the range of 15–30% and, at the same time, ensures a 40–60% increase in the delivery capacity of project offices. The results obtained confirm the hypothesis that the function of the Project and Business Development Manager, acting as a cross-functional leader, acquires pivotal importance in overcoming cross-functional and interdepartmental divides.
It has been established that achieving target SLA indicators becomes possible only under conditions of a deep coupling of technical and commercial competencies within a unified management framework. This, in turn, demonstrates that the effectiveness of delivering complex technological projects in a high-uncertainty environment is determined not only by the degree of engineering elaboration embedded in the solution, but also by the quality of institutionalized coordination among project participants. The provisions presented in the article possess practical value for senior executives and managers responsible for business development and the optimization of implementation processes for complex technological initiatives.
