WMF product development process/Develop

Backend and front-end development takes place and carry the selected concept forward to implementation.  Quality and performance are important checks.  If any issues or bugs are found the feature may roll back to Design depending on the severity of issues found. Testing via labs, prototyping, a/b tests, surveys, flow analysis, user sessions, and community validation of progress. The tasks are driven by Product Managers, Engineering and User Experience and could include participation, validation or checkins with Research & Data, Architecture and Operations, Data Analyst, Community Liaisons, Operations, Team Practices, API and Services, Performance and Architecture. Bugs, analysis and feedback in this round can send features back to the design phase.
