Therefore, 5 case-studies were developed inside agile projects, in a company that values innovation, aiming to identify how (un)happiness impacts on software engineers in agile environments. According to the answers gathered from 67 participants through a survey and using a cross-analysis, (un)happiness characteristics were identified as anxiety and frustration on younger respondents and unhappy ones, and high satisfaction and collaboration on happier ones.
