The Psychology of Requirements Engineering: Cognitive Biases, Human Behavior, and Stakeholder Dynamics in Software Development

This research paper, “The Psychology of Requirements Engineering: Cognitive Biases, Human Behavior, and Stakeholder Dynamics in Software Development,” explores the critical yet often overlooked psychological factors that influence the success and failure of requirements engineering (RE) in software development. The study investigates how cognitive biases (such as confirmation bias and anchoring), emotional intelligence, interpersonal communication, and team dynamics (including groupthink and stakeholder pressure) impact requirements elicitation, analysis, and validation processes. Using a mixed-methods approach involving surveys, interviews, and observational analysis, the paper provides both quantitative and qualitative insights into how human behavior shapes software requirements. Key findings highlight that psychological factors significantly contribute to requirement misinterpretation, communication gaps, and project inefficiencies. The research also proposes the Psychological Requirements Risk Framework (PRRF), which aims to help practitioners identify and mitigate human-centered risks in RE processes. Real-world case studies, including large-scale software failures, are analyzed to demonstrate the practical consequences of ignoring psychological dimensions in software engineering. The study ultimately emphasizes the need to integrate behavioral psychology, emotional intelligence training, and structured elicitation techniques into both academic curricula and industry practices.
