Cognitive load is the amount of mental processing required for a developer to perform a task. The notion of cognitive flow, which I've been looking at for actually over 20 years now, is this idea of supporting developers getting in flow. It's not just around mechanical aspect of people being interrupted; it also includes human awareness aspects as well. So together, we feel these are the three most important kind of ways that we can make improvements to developer experience.
“The three core dimensions of developer experience are feedback loops, cognitive load, and flow state."
Margaret-Anne (Peggy) Storey and Abi Noda are the coauthors of the recently published ACM paper “DevEx: What Actually Drives Productivity”. In this episode, we discussed how we can better measure and improve developer productivity using a developer-centric approach. Peggy and Abi first began by explaining the importance of socio-technical factors in software development. They also shared their view on the well-known SPACE and DORA metrics, and pointed out the danger of misusing and abusing the DORA metrics. Peggy and Abi then explained the three core dimensions of developer experience from their latest paper, which are feedback loops, cognitive load, and flow state. Towards the end, Peggy and Abi shared tips on how we can start measuring developer experience, including how to conduct developer surveys properly.
