TL;DR
This paper tackles how to measure developer productivity in the era of AI coding assistants by conducting a sequential mixed-methods study at BNY Mellon, combining a large-scale DX survey with in-depth interviews. It demonstrates that productivity is multi-dimensional, identifying six factors that span development, deployment, and long-term career impact, including self-sufficiency, cognitive load, task throughput, peer review, technical expertise, and ownership. The work shows that high tool satisfaction does not guarantee substantial time savings and argues that existing frameworks like SPACE and DORA miss long-term considerations, proposing a holistic, context-aware evaluation approach. The findings offer operational guidance for both industry and academia to measure AI-assisted productivity more comprehensively and responsibly, with implications for onboarding, skill development, and workflow design.
Abstract
Measuring developer productivity is a topic that has attracted attention from both academic research and industrial practice. In the age of AI coding assistants, it has become even more important for both academia and industry to understand how to measure their impact on developer productivity, and to reconsider whether earlier measures and frameworks still apply. This study analyzes the validity of different approaches to evaluating the productivity impacts of AI coding assistants by leveraging mixed-method research. At BNY Mellon, we conduct a survey with 2989 developer responses and 11 in-depth interviews. Our findings demonstrate that a multifaceted approach is needed to measure AI productivity impacts: survey results expose conflicting perspectives on AI tool usefulness, while interviews elicit six distinct factors that capture both short-term and long-term dimensions of productivity. In contrast to prior work, our factors highlight the importance of long-term metrics like technical expertise and ownership of work. We hope this work encourages future research to incorporate a broader range of human-centered factors, and supports industry in adopting more holistic approaches to evaluating developer productivity.
