  Information technology (IT) organizations are increasing the use of agile
practices, which are based on a people-centred culture alongside the software
development process. Thus, it is vital to understand the social and human
factors of the individuals working in agile environments, such as happiness and
unhappiness and how these factors impact this kind of environment. Therefore,
five case-studies were developed inside agile projects, in a company that
values innovation, aiming to identify how (un)happiness impacts software
engineers in agile environments. According to the answers gathered from 67
participants through a survey, interviews and using a cross-analysis, happiness
factors identified by agile teams were effective communication, motivated
members, collaboration among members, proactive members, and present leaders.
