"Engineering leaders have long sought to improve the productivity of their developers, but knowing how to measure or even define developer productivity has remained elusive. Past approaches, such as measuring the output of developers or the time it takes them to complete tasks, have failed to account for the complex and diverse activities that developers perform. Thus, the question remains: What should leaders measure and focus on to improve developer productivity?"
"Today, many organizations aiming to improve developer productivity are finding that a new developer-centric approach focused on developer experience (also known as DevEx) unlocks valuable insights and opportunities."
So, subjective experience?
"Developer experience encompasses how developers feel about, think about, and value their work. In prior research, we identified more than 25 sociotechnical factors that affect DevEx. For example, interruptions, unrealistic deadlines, and friction in development tools negatively affect DevEx, while having clear tasks, well-organized code, and pain-free releases improve it."
"A common misconception is that DevEx is primarily affected by tools. Our research, however, shows that human factors such as having clear goals for projects and feeling psychologically safe on a team have a substantial impact on developers' performance."
They go on to say the "three dimensions of DevEx" are feedback loops, cognitive load, and flow state.
