Developer experience (DX) is crucial for keeping developer teams productive, happy, and focused on work that aligns with business aims. To create good DX, experts recommend asking developers directly about their needs and frustrations, continuously iterating and improving tools and processes, choosing the right tools wisely, measuring impact, avoiding technical debt, and leveraging open-source projects. The next great leap forward in productivity may come from tools that gather expertise knowledge from platforms like LinkedIn or GitHub, or abstract the development process to a higher level, allowing teams to focus on innovation rather than infrastructure management.
