The Maintainer’s Dilemma “I want to grow my open source project/community, but that’s going to require a lot of time and effort that I don’t have… So I guess I’ll just wait and hope for the best.” Community over xkcd Code NA 2025 source:

What is a “flywheel?” “a mechanical device that uses the conservation of angular momentum to store rotational energy; a form of kinetic energy that is proportional to the product of its moment of inertia and the square of its rotational speed. A flywheel is a heavy wheel attached to a rotating shaft to smooth the transfer of power from an engine to a machine.” – The Engineering Choice Community over Code NA 2025

What is a “flywheel?” For the Physicists in the room… 1 2 Iw 2 ​ w = angular velocity, I = moment of inertia Community over Code NA 2025

What is a “flywheel?” Metaphorically in Community a self-reinforcing loop or cycle that, once set in motion, gains momentum and drives continuous growth and improvement Community over Code NA 2025

Developer Experience (DevEx) _”…the journey of developers as they learn and deploy technology, which if successful, focuses on eliminating obstacles that hinder a developer or practitioner from achieving success in their endeavors.” – Jessica West, Director of Education & Customer Experience (Chronosphere) Community over Code NA 2025

DevEx isn’t new REF: F. Fagerholm and J. Münch, “Developer experience: Concept and definition,” 2012 International Conference on Software and System Process (ICSSP), Zurich, Switzerland, 2012. Community over Code NA 2025

DevEx isn’t new “New ways of working such as globally distributed development or the integration of self-motivated external developers into software ecosystems will require a better and more comprehensive understanding of developers’ feelings, perceptions, motivations and identification with their tasks in their respective project environments.” REF: F. Fagerholm and J. Münch, “Developer experience: Concept and definition. 2012.” Community over Code NA 2025

DevEx isn’t new “…developer experience could be defined as a means for capturing how developers think and feel about their activities within their working environments, with the assumption that an improvement of the developer experience has positive impacts on characteristics such as sustained team and project performance.” REF: F. Fagerholm and J. Münch, “Developer experience: Concept and definition. 2012.” Community over Code NA 2025

Developer Experience (DevEx) The impacts of the experience Negative Positive Time wasted (technical debt, Frictionless onboarding, poor tooling, bad docs, etc.) workflows, docs Losing developers (attrition, Clear standards, guardrails burnout, etc.) Fast feedback loops Lost opportunities (missed deadlines, lost revenue, etc.) Community over Code NA 2025

Developer Experience (DevEx) Core Dimensions 1. Feedback Loops 2. Cognitive Load 3. Flow State Community over Code NA 2025

Developer Experience… …for Open Source projects? Community over Code NA 2025

It starts with a single push 1. Follow your own contribution guide. Where do you get stuck? 2. Ask a friend who isn’t familiar with the project to try. Compare notes. 3. Pick the single biggest point of friction and fix it this week. Community over Code NA 2025

Conclusion Stop hoping for community growth and start engineering it. DevEx principles in business can be applied to OSS projects. Focus on Onboarding, Tooling, Feedback, and Recognition. Small, consistent improvements create powerful, sustainable momentum. Community over Code NA 2025
