Are happy developers more productive?

Let’s look at some research studies together to see whether “happy developers are more productive”. I will let you know my take on it, and how it relates to the study I did on developer experience. We talk about: - whether happy developers are more productive - what makes developers happier at work - with which negative consequences do you have to reckon if developers are unhappy - and what are the most important factors that make developers more satisfied at work.
