Distinguishing DevEx from other Concepts Connect.Tech 2024

Distinguishing DevEx from other Concepts User Experience (UX) Developer Productivity Focus: prioritizing the end users usability and Focus: measured in terms of output, with an overall experience; aim to make software emphasis on efficiency and performance. intuitive, easy to use, and enjoyable to interact Context: metrics like “time to release”, “number of with. pull requests”, or “deployment frequency”. Context: involves user research, wireframes, Differs from DevEx: they don’t capture the full testing product to optimize user satisfaction. experience of developers, while DevEx Differs from DevEx: _DevEx focuses on making encompasses efficiency, the satisfaction, well- tools, processes, and environments that devs use being, and support structure of devs. efficient and pleasant.

Distinguishing DevEx from other Concepts Developer Experience (DevEx) Focus: holistic view encompassing all aspects of the developer journey (usability, efficiency, satisfaction, etc.) Unique: integrates elements of UX and productivity, but with a broader scope of psychological safety, community, and feedback loops.

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. Connect.Tech 2024

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.” Connect.Tech 2024

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.” Connect.Tech 2024
