İnsan faktörlerinin Türkiye'deki yazılım projelerinin başarısı üzerindeki etkisi

Software development is not a smooth process. Many software projects are delayed, failed, abandoned, or rejected for various reasons. One significant cause of failure is the neglect of human factors. Contrary to popular belief, software development is more of a human activity than a purely technical process, involving interactions between customers and development teams. The Agile Manifesto was a major step in acknowledging the importance of people in the software development process. The formation of a cohesive software team underscores the relevance of human factors. Teams make decisions on many critical aspects of projects. Human interaction within the team is essential for building motivation, trust, communication, and mutual support, which are key to sound decision-making. To meet customer and stakeholder expectations, it is important to follow project delivery strategies that involve them throughout the process. Additionally, team managers are responsible for both the team and the project. Thus, both managers and teams must remain aware of human factors to ensure project success. This thesis proposes a research model consisting of five human factors and their components. Their relative weight and importance in software project success are analyzed through surveys conducted with software development team members in Turkey. Two predictive models—Multiple Linear Regression (MLR) and Ridge Regression—are applied to the survey data. The MLR model is preferred due to the higher score R-squared (R²). The MLR model suggests that "Project" and "Management" are the main factors contributing to software project success, followed by "Team." A total of 312 respondents participated in the survey, with 141 completed responses covering 63 questions.
