Motivated software engineers are engaged and focused, while satisfied ones are happy

Context -- Motivation and job satisfaction are not the same thing, and although business organization research recognized this a long time ago, in Software Engineering research, we have not. As a result, thirty years of research on motivation in software engineering has produced knowledge on what makes software engineers generally happier, but not about how to increase their motivation. Goal -- In this article, we aim to identify visible signs of a software engineer who is motivated to work. Method -- We describe a field study in which 62 practitioners in Brazil reported their view of "motivation" in the context of their practical work. Data was collected by means of audio-recorded semi-structured interviews, and a thematic analysis was applied to identify the most relevant descriptors of motivation. Results -- Our data reveal that (1) motivated Software Engineers are engaged, focused, and collaborative; and (2) the term "motivation" is used as an umbrella term to cover several distinct organizational behaviours that are not necessarily related to the individual's desire to work. Conclusions -- Without a clear picture of the difference between these two concepts, work-based motivation programs may not be designed effectively to address either turnover or performance issues. Overall, this work indicates the need for a more effective conceptual system to investigate and encourage both job satisfaction and work motivation in software engineering research and practice.
