The 2025 JetBrains Developer Ecosystem Survey of 24,534 developers across 194 countries reveals a striking finding: 62% of developers say non-technical factors impact their productivity more than technical factors (51%). For the first time in the survey’s history, meetings, communication overhead, and work environment matter more than CI/CD pipelines, dev tools, and tech stacks. This contradicts decades of focus on optimizing the technical side of developer productivity metrics.
While engineering organizations obsess over deployment frequency and lead times, developers are drowning in what Meta calls “dark matter” overhead—standup updates, alignment meetings, chat, email, and task management that doesn’t show up in velocity metrics. The data suggests the industry has been optimizing the wrong end of the problem.
Non-Technical Factors Now Outweigh Technical Tools
JetBrains Research published its findings in October 2025, marking the first time non-technical factors (62%) surpassed technical factors (51%) in developer-reported productivity impact. Non-technical factors include meeting culture, communication overhead, work environment, peer and manager support, job design, and actionable feedback—elements rarely captured by traditional developer productivity metrics.
“Internal collaboration, communication, and clarity are now just as important as faster CI pipelines or better IDEs,” the JetBrains Research team concluded. The survey, conducted between April and June 2025, found technical managers want 2× more focus on communication issues and nearly twice as much investment in reducing technical debt compared to tool optimization.
This challenges the entire approach to developer productivity optimization. If communication overhead and meeting culture impact productivity more than technical tooling, organizations have been investing in the wrong areas. Developers need meeting-free time more than they need faster build pipelines.
Two-Thirds of Developers Say Metrics Don’t Reflect Reality
Stack Overflow’s 2025 Developer Survey of 49,000+ respondents delivered another blow to conventional productivity measurement: 66% of developers do not see existing metrics as a realistic representation of their actual performance. This is a devastating indictment of how the industry measures developer productivity.
Common metrics like lines of code, number of commits, pull request count, and story points fail to capture what developers actually do. The disconnect is clear: companies measure commit velocity while developers want communication quality measured. One Hacker News discussion summarized the community consensus: “Output metrics like lines of code, PRs, commits are ineffective—even lean metrics like cycle time are far from indicators of effectiveness or productivity.”
If two-thirds of developers say the metrics don’t reflect their work, then productivity measurement is fundamentally broken. Companies make decisions about promotions, bonuses, and resource allocation based on metrics that developers themselves reject as meaningless.
The “Dark Matter” Overhead Metrics Can’t Capture
Knowledge workers spend 40-60% of their workweek in meetings, leaving limited time for actual development work. Meta engineering coined the term “dark matter” to describe the invisible overhead developers deal with daily: standup updates, cross-functional alignment, chat, email, and task management. This overhead doesn’t appear in velocity metrics or commit counts.
Research shows 60% of knowledge worker time is spent in meetings, emails, chats, and collaboration while only 40% is devoted to individual work. This is “collaboration debt”—the overload of notifications, emails, meetings, and information flow that exceeds employees’ capacity to process it. Context switching between meetings and coding is particularly costly, fragmenting deep work time into usable chunks.
One organization achieved remarkable results by addressing communication overhead directly: 78% reduction in meeting time, 45% increase in project velocity, and 89% improvement in team satisfaction through communication architecture redesign. These gains exceed what most technical optimizations deliver.

DORA and SPACE Identify Problems But Offer No Solutions
Even research-backed frameworks like DORA metrics and the SPACE framework have significant limitations. DORA metrics encourage speed over quality by focusing heavily on Deployment Frequency and Lead Time for Changes, potentially leading teams to prioritize rapid releases at the expense of thorough testing and team well-being. SPACE lacks measurement specifics—it identifies what dimensions matter (satisfaction, performance, activity, communication, efficiency) but provides almost no guidance on what specific metrics to track, making implementation highly subjective.
Framework comparison research reveals universal challenges across all developer productivity frameworks: the “now what?” problem where frameworks excel at diagnosing issues but provide limited guidance on specific actions to improve. Organizations adopt DORA or SPACE thinking they’ll solve productivity measurement, then discover the frameworks show them what’s broken without telling them how to fix it.
DORA is too narrow—it captures operational efficiency while overlooking product quality, user satisfaction, and developer well-being. SPACE is too broad—its lack of implementation specifics leaves teams guessing at how to actually measure the five dimensions. Neither framework adequately addresses the non-technical factors that developers now say matter most.
What Developers Want Measured vs What Companies Track
Developers want to be asked about team processes and communication quality, satisfaction with tools and workflow, peer and manager support systems, and overall well-being. Instead, companies measure lines of code, commits, pull requests, story points, and deployment frequency—the exact metrics 66% of developers say don’t reflect their performance.
The DX Core 4 framework offers a better approach, balancing speed, effectiveness, quality, and business impact together rather than chasing single metrics. Over 300 organizations using this approach achieved 3-12% engineering efficiency gains by measuring what actually matters. Booking.com quantified a 16% productivity lift by focusing on developer-reported experience data alongside operational metrics.
The most effective teams combine system metrics with developer-reported experience data to capture the whole picture. This means surveying developers about communication quality, support systems, and work-life balance—not just counting commits and monitoring deployment frequency.
Practical Solutions: Meeting Reduction and Async-First Workflows
Organizations addressing non-technical factors are seeing measurable gains that exceed typical technical optimizations. Many engineering teams have implemented “meeting-free Wednesdays” to ensure developers have at least one full day for uninterrupted focus time. Async-first workflows—attempting to handle issues asynchronously first, only scheduling meetings if that fails—deliver results: 40% reduction in unnecessary meetings and 28% increase in project delivery speed.
The evidence is clear: addressing communication overhead and meeting culture produces bigger productivity improvements than optimizing CI/CD pipelines. Organizations using the DX Core 4 approach achieved consistent 3-12% efficiency gains across 300+ organizations by balancing speed, effectiveness, quality, and business impact instead of optimizing deployment frequency in isolation.
Key Takeaways
- 62% of developers report non-technical factors (meetings, communication, work environment) impact productivity more than technical factors (51%)—a paradigm shift in understanding developer productivity metrics
- 66% of developers reject existing metrics as unrepresentative of their actual performance, exposing a fundamental crisis in productivity measurement
- Knowledge workers spend 40-60% of time in meetings and communication, creating “dark matter” overhead that velocity metrics completely miss
- DORA metrics and SPACE framework identify problems but lack actionable solutions—DORA is too narrow (speed over quality), SPACE is too broad (no implementation specifics)
- Organizations that reduce meeting overhead see bigger productivity gains than those optimizing technical infrastructure—one company achieved 78% meeting time reduction and 45% velocity increase through communication redesign
The industry’s decades-long focus on technical optimization has missed what developers keep saying: productivity is less about how fast you deploy and more about whether you can actually focus on coding. Stop measuring deployment frequency. Start measuring meeting culture. The data says it matters more.
