Model and Procedure for Assessing the Qualification of a Software Developer

Developers’ qualifications and their professional development are the important aspects of IT project’s success. Software developers are interested in advancing their careers and improving their skills in order to maintain their level of professional value both for organizations and for the labor market. However, the evaluation of developers' qualifications is frequently based on the subjective opinion of managers, which can negatively affect the further professional development of employees. Quantitative metrics become particularly relevant in the assessment, because they can reduce the level of subjectivity. Therefore, the objective of this work is to develop data model for assessing the qualifications of software developers. The proposed model is based on data from version control system, knowledge management system and task management system. In order to collect information from these systems, as well as to carry out calculations, a decision support system based on the Node.js software platform was developed. The designed model and system were implemented in a software development company. For the assessment of relations between selected metrics and developers’ qualifications a multiple regression analysis was carried, where the employee's qualification rating assessed by the manager was the dependent variable. As a result, 2 models were prepared to assess the responsibility and the level of technical skills. Together, these models will provide a more comprehensive picture of developer’s qualification.
