A Comparative Analysis of Agile Teamwork Quality Models

[Background] The literature reports multiple models (or instruments) for measuring Teamwork Quality (TWQ) for Agile Software Development However, these models have different constructs and measures, and there is a lack of empirical evidence comparing them. [Goal] This study fills this gap by analyzing if two agile TWQ models yields equivalent results. [Method] First, we mapped the models’ variables given their definitions. Then, we collected data using both a BN model (Baysean Network model), TWQ-BN, and Structural Equation Modeling, TWQ-SEM, by interviewing 162 team members from two software development companies. We analyzed the collected data by applying the Bland-Altman method. [Results] We obtained enough evidence to conclude that the results for Communication, Coordination, Cohesion and Mutual Support are not equivalent. Conversely, we did not have enough evidence to claim that the models do not agree for measuring Effort and Balance of member contribution. [Conclusions] The results of this study detail how two state-of-the-art agile TWQ compare in terms of their measures as well as potential research areas for further investigation.
