Resumen:
Agile Software Development adoption has increased due to its characteristics that allow
fast responses to business requirements change in the volatile software development indus-
try. According to the agile principles and to studies published in the literature, teamwork
related factors have positive impact on the success of ASD projects. In the literature, there
are some instruments with the purpose of assessing Teamwork Quality, but they might not
be useful in concrete situations that demand prediction, and problem diagnosis or progno-
sis. Therefore, in this thesis, we present a process based on a Bayesian Network model
that enables measuring, prediction, assessment, and continuous improvement of Teamwork
Quality in the context of Agile Software Development. The model was built by following a
top-down approach based on the knowledge of a specialist, and it can adapted to fit a given
context. The proposed solution, comprised by the model and process, was evaluated in re-
gards to its practical utility in a case study with three teams of one organization, and the
results were positive. Given the fact that the model presented has a questionnaire as source
of data, we evaluated the level of agreement between respondents in different roles within a
team, including project manager, technical leader, and development teams. As a result, we
verified that the results with considerable level of agreement were calculated only for the the
managers and development teams roles. Moreover, we realized an empirical study with two
organizations to compare the model presented in thesis with another model presented in the
literature, in regards to their composition, including their variables and measures. According
to the results of the study, considering only the set of equivalent variables presented in both
models, they are similar from the perspective of their constructs; and the results calculated
by both models, in general, are also similar. Finally, we present practical use cases based
on real experiences with the purpose of exemplifying how to use the model presented in this
thesis.
