Modeling the structure of roles in a project task management system

Abstract

Relevance. In modern project management information systems, a clear role structure is critical for the effective organization of teamwork. The Scrum, XP, and DSDM methodologies involve the distribution of authority and access to resources according to the functional roles of participants. This is especially relevant in large-scale projects with a multi-level access structure, where proper role modeling helps to increase productivity, security, and controllability of development processes. Insufficient formalization of roles can lead to duplication of functions, conflicts in teams, and a decrease in overall management efficiency. Therefore, the development of a flexible and adaptive model of role distribution is an important step in creating modern systems for planning and controlling tasks.

Objective. The purpose of the article is to model the structure of roles in the project task management system, taking into account the main project management methodologies, such as Scrum, XP, DSDM. The article analyzes the key roles and responsibilities within each of these methodologies, as well as compares these models in terms of their suitability for a task planning system. In addition, the article aims to investigate which of the models is the most optimal for organizing tasks in systems with multi-level access.

Research methods. Comparative analysis, modeling.

Results. A comparative analysis of three project management methodologies - Scrum, XP, and DSDM - was conducted to determine their effectiveness in the context of building a task management system. Based on the role structure proposed in Scrum, a multi-level model of team role distribution was developed, which takes into account the skill level of each participant. The proposed model was improved by introducing additional roles, which allowed the system to better adapt to the real working conditions of modern IT teams. For each role, areas of responsibility and levels of access to the system's functionality were defined, which allows for flexible process management, enhanced security, and convenient scalability. Particular attention is paid to detailing the roles of developers depending on their professional level (junior, middle, senior), which positively affects the effectiveness of team interaction, quality control of tasks performed, and the process of mentoring in the team.

Conclusions. A model of the structure of roles in the Scrum-based project task management system has been developed, taking into account extensions that meet the realities of the modern IT industry. The influence of each role on the functioning of the management system is determined and it is found that it is the combination of basic Scrum roles with additional specialized roles that allows to form a stable multi-level system that can adapt to changes in the project environment.
