Yes, good DevEx increases productivity. Here is the data.

Recent research highlights the significant impact of developer experience (DevEx) on productivity and innovation, providing concrete data to support the benefits traditionally touted by anecdotal evidence. Conducted in collaboration with the company DX, the study identifies key DevEx factors—flow state, cognitive load, and feedback loops—as crucial contributors to individual, team, and organizational success. Developers with time for deep work and engaging projects report higher productivity, while those experiencing reduced cognitive load due to better understanding and intuitive processes feel more innovative. Efficient feedback loops are linked to increased innovation and reduced technical debt. As such, companies like Adobe and Etsy have emphasized the importance of investing in DevEx to enhance developer satisfaction and business outcomes. The study offers a framework and data-driven insights to help business leaders advocate for and measure the impact of DevEx, underscoring its role as a strategic lever for profitability and innovation.
