VISUALIZATION OF THE ORGANIZATIONAL STRUCTURE OF AN IT COMPANY USING UML

Abstract

This research paper examines the process of modeling the organizational structure of an IT company based on the Unified Modeling Language (UML). The main objective of the study is to create models that reflect the interaction of roles, the enterprise structure, and the business processes within the organization’s information system.  Choosing this particular set of diagrams based on need opens up key architectural perspectives, as recognized in software engineering’s «4+1 View Model».

Within the study, the key UML diagrams were developed: the use case diagram, class diagram, sequence diagram, and activity diagram. Each of these diagrams highlights a specific aspect of the IT company’s operation. In particular, the use case diagram models the interaction among the main system actors: analyst, system administrator, project manager, HR manager, developer, and department head. The class diagram describes the logical structure of the system, including entities such as Employee, Department, Team, Project, and Task. The sequence diagram illustrates the dynamics of creating and approving a technical specification within the document management system, while the activity diagram demonstrates the process of handling a client’s technical request by the support service.

The proposed modeling approach provides a comprehensive understanding of the internal processes of an IT company, enhances the efficiency of interdepartmental communication, and establishes a solid foundation for further software infrastructure design. The research results can be used for educational purposes as well as an analytical tool for improving management and organizational processes in the IT domain.
