The Science of Engineering Pace: Why Comparing Velocity Is the Wrong Metric

4 the researchers behind it — "She ships twice as fast as me — I must not be cut out for this" is the kind of thought software engineers rehearse constantly, usually at 11pm starin

GitHub (Microsoft Research) / DORA co-founder

Nicole Forsgren

Known for:Co-creator of the SPACE framework for developer productivity and lead researcher on the DORA State of DevOps reports

Key findings

  1. 2021

    With Storey, Maddila, Zimmermann, Houck and Nagappan, Forsgren introduced the SPACE framework — arguing that developer productivity cannot be reduced to any single metric and that satisfaction/wellbeing, performance, activity, communication/collaboration, and efficiency/flow are five independent dimensions each requiring distinct measurement. ↗

  2. 2023

    DORA's 2023 State of DevOps Report, building on Forsgren's research program, found that high-performing engineering teams outperform low performers across all four DORA metrics simultaneously — they do not trade off speed against stability but achieve both through organizational and cultural practices. ↗

Construx Software

Steve McConnell

Known for:Historical audit of the '10x programmer' origin story and author of Code Complete — known for tracing software development claims back to their primary sources

Key findings

  1. 2020

    McConnell traced the '10x programmer' claim to the 1968 Sackman/Erikson/Grant study of 12 programmers and documented how the ratio — originally about debugging time on a single task — was repeatedly cited, decontextualized, and amplified over five decades into a broad claim about general developer productivity. ↗

University of Victoria

Margaret-Anne Storey

Known for:Research on developer experience, developer pain points, and the social dimensions of software engineering — including co-authorship of the SPACE framework

Key findings

  1. 2019

    With Zimmermann, Storey surveyed 2,000 Microsoft developers and found interruptions and task-switching were the most commonly cited productivity impediment — more so than tool performance or code complexity — highlighting environmental and workflow factors as primary levers invisible to peer output comparisons. ↗

  2. 2021

    As a co-author of the SPACE framework with Forsgren and colleagues, Storey argued that any single productivity metric — including velocity, lines of code, or ticket throughput — will systematically obscure at least four other independent dimensions of what makes a developer genuinely productive. ↗

Google

Ciera Jaspan

Known for:Research on developer productivity measurement at scale, including studies on how team and organizational context shapes individual output at Google

Key findings

  1. 2019

    With Murphy-Hill and colleagues, Jaspan's research at Google found that individual performance was more strongly shaped by team-level factors — code review culture, on-call load, meeting density, psychological safety — than by individual effort, suggesting that peer velocity comparisons conflate personal capability with structural environment. ↗
