WMF product development process

Overview
The Wikimedia Foundation Product Development Process has a set of phases that centers on tasks and potential stakeholders involved. The high level draft presented is a set of tasks and stakeholders involved in our current and future development. This was evolved from an earlier draft review that incorporated feedback from multiple processes and expectations.

The process will continue to evolve and the tasks and stakeholders presented are a general guideline and potential checklist. Each team may have its own mix of responsibilities or stakeholders, and some phases may not apply. Community involvement or interaction is expected throughout the phases, ideally through established team or feature feedback mechanisms and in collaboration with our Community Liaisons.

A more detailed effort to restructure how the WMF plans and executes software engineering, known as the SPDPP (Software Product Development Process Proposal), involving Engineering, Product departments and the Team Practices group, will contribute to this draft as it evolves.

Concept
New feature proposals and submissions for current problems or new ideas. These items could involve or be generated from areas like general discovery or ideation, research, technical debt and/or strategy. Submissions could come from anyone but generally are from our Community members, Community Liaisons, internal Product Audiences, Design Research, Research, Partnerships and Communications.

Plan
Planning and prioritization involve defining the inputs (people, forecasting, resources), outputs (tasks), outcomes (metrics), defining milestones, dependencies and maintenance tasks. These tasks are generally driven by Product Managers, Engineering and User Experience and may include participation, validation or checkins with Communications, Team Practices, Security, Community Liaisons, API/Services, Release Engineering and Legal teams.

Design
Validation of solutions proposed and testing of prototypes for those proposals. Testing via labs, prototyping, a/b tests, surveys, flow analysis, user sessions, and community validation of ideas proposed. The tasks typically involve User Experience, Design Research, Research, Architecture and Operations, Data Analysts and Community Liaisons.

Build
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. The tasks are generally driven by Product Managers, Engineering and User Experience and could include participation, validation or checkins with Operations, Team Practices, API and Services, Performance and Architecture. Bugs and feedback in this round can send features back to the design phase.

Release
Reviews by dependent stakeholders from the concept stage to validate concept completion. Community review and initial feedback on the development may influence release & rollout timing. Teams will be analyzing performance and adoption. If any issues or bugs are found the feature may roll back a stage or two depending on the severity of issues found. Announcements or events may also be created around releases. These tasks could apply to alpha, beta and production level feature releases. The tasks are generally driven by Product Managers, Communications, Community Liaisons, Release Engineering and could include participation, validation or checkins with Operations, Legal, and Security. Bugs and feedback in this round can send features back to the build phase.

Maintain
After a feature is released ongoing maintenance is measured through feedback loops and analysis, retrospectives, metrics and impact reviews and identification of improvements. Community review and feedback on real usage and interaction is measured and teas will be analyzing performance and adoption. Improvements or new features restart the process and planning and milestones will be created. The tasks generally driven by Product Managers, Performance, Data Analysts, Design Research, Research, Community Liaisons and Security. Any iterations to the product will result in the process restarting.
