Developer productivity is about more than an individual’s activity levels or the efficiency of the engineering systems, and it cannot be measured by a single metric or dimension. In this talk, I will discuss a decade of my productivity research. I will show how to use the SPACE framework to measure developer productivity across multiple dimensions to better understand productivity in practice. I will also discuss common myths around developer productivity and propose a collection of sample metrics to navigate around those pitfalls. Measuring developer productivity at Microsoft has allowed us to build new insights about the challenges remote work has introduced for software engineers, and how to overcome many of those challenges moving forward into a new future of work. Finally, I will talk about how I expect that the AI revolution will change developers and their productivity.
