Um modelo de avaliação de efetividade do trabalho em equipe baseado em fatores emocionais para projetos scrum.

Abstract

In Agile Software Development (ASD), teamwork is essential for the success of agile projects. Various models have been proposed to evaluate team effectiveness in this context, based on factors such as communication, coordination, mutual support, and shared leadership, and others. However, these models share a common limitation: they have given little consideration to emotional factors in assessing effectiveness. Activities in agile projects, such as decision-making, effort estimation, user story implementation, coding, and testing, are influenced by emotional factors. Aspects such as delivery pressure, requirement changes, exhaustion, and burnout impact effectiveness but have received little attention in existing effectiveness models. To address this gap, we propose the Scrum Team Effectiveness Model - Emotional Factors (STEM-EF), which integrates emotional factors into effectiveness evaluation, considering the ceremonies, artifacts, and roles specific to Scrum. The instrument is based on four emotional factors: Emotional Intelligence; Interpersonal Skills; Conflict Resolution; and Psychological Safety. The validation of STEM-EF was conducted through qualitative and quantitative studies. The Technology Acceptance Model (TAM) was used to evaluate usefulness; perceived ease of use; attitude; and intention to use. Content analysis of the items, based on the Content Validity Index, evaluated their relevance, coherence, and simplicity. Eleven Scrum experts, 56 Scrum team members, and two psychologists were consulted through focus groups, interviews, and surveys. The results indicate that the instrument is valid and useful for assessing Scrum team effectiveness through emotional factors.
