DORA data shows that speed and quality are not trade-offs but reinforcing: high-quality software is built faster because less time is spent fixing defects, and fast iteration (many small steps) enables quality by making impacts observable. Teams with strong DORA scores spend 44% more time on new features and are better at achieving commercial goals, suggesting that sacrificing quality or speed to cut costs actually results in slower, more expensive, worse software. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What do DORA metrics say about the trade-off between speed and quality in software development DORA research indicates there is no inherent trade-off between speed and quality. Teams with strong stability and throughput scores are better able to achieve commercial goals and spend 44% more of their time on new features rather than fixing problems, suggesting that building quickly and building well reinforce each other rather than conflict. _daily.dev surfaces engineering practice research like this for teams rethinking how they balance delivery speed and quality._ ## Similar posts on daily.dev - [Mastering DORA Metrics: A Strategic Guide to Engineering Performance](https://daily.dev/posts/mastering-dora-metrics-a-strategic-guide-to-engineering-performance-jrenetlws) · Medium · 1 upvotes · 1 comments - [Stop Guessing, Start Improving: Using DORA Metrics and Process Behavior Charts](https://daily.dev/posts/stop-guessing-start-improving-using-dora-metrics-and-process-behavior-charts-n4pab6eid) · InfoQ · 0 upvotes · 0 comments - [DORA metrics are lying to you and AI is making it worse](https://daily.dev/posts/dora-metrics-are-lying-to-you-and-ai-is-making-it-worse-p5ki14fbt) · LeadDev · 0 upvotes · 0 comments - [Feeling Fast, Delivering Slow: Why Your AI Adoption Still Hasn't Paid Off](https://daily.dev/posts/feeling-fast-delivering-slow-why-your-ai-adoption-still-hasn-t-paid-off-r8tka8vfj) · Tech Lead Digest · 2 upvotes · 0 comments --- Tags: [#project-management](https://daily.dev/tags/project-management), [#dora-metrics](https://daily.dev/tags/dora-metrics) [View this post on daily.dev](https://daily.dev/posts/the-project-management-lie-everyone-believes-cdhpmmffg) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"The Project Management LIE Everyone Believes","url":"https://daily.dev/posts/the-project-management-lie-everyone-believes-cdhpmmffg","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/the-project-management-lie-everyone-believes-cdhpmmffg"},"datePublished":"2026-08-03T16:35:13.831Z","dateModified":"2026-09-14T06:52:36.400Z","description":"The iron triangle of project management — fast, good, cheap, pick two — is challenged by DORA metrics research.
