Plan:FY18-19

Program Manager:	Corey Floyd
Product Manager:	Cindy Cicalese
Executive Sponsor:	Victoria Coleman

Goals and Outcomes

Annual Plan Goals:	Knowledge as a Service/Foundational Strength: Evolve our systems and structures
Program Goal:	Empower the Wikimedia Foundation to accomplish its goals of Knowledge Equity and Knowledge as a Service by evolving and investing in our technology stack to improve its flexibility, maintainability, and sustainability
Outcomes:	Outcome 1: Engineers have a clear understanding of our technology stack and the plan to better scale, maintain and test it Outcome 2: Engineers are able to access more functionality of the stack using well encapsulated components and well defined APIs Outcome 3: Engineers better understand our current architecture and coding standards and where to find them

Targets

Outcome	Target Description	Measurement Method
Outcome 1: Engineers have a clear understanding of our technology stack and the plan to better scale, maintain and test it	Engineers can confidently port specific individual components of Parsoid and verity its correctness and performance without requiring a full port to be ready	Ensure that token transformers and DOM passes have unit tests and a unit testing framework with suitable mocks
Outcome 1: Engineers have a clear understanding of our technology stack and the plan to better scale, maintain and test it	WMF Staff and volunteers can view and understand the current architecture, proposed architecture, implementation plan as well as the parser unification plan	Ensure the architecture and plan documents exists, are publicly accessible, and are announced on public communication channels
Outcome 2: Engineers are able to access more functionality of the stack using well encapsulated components and well defined APIs	Engineers can implement a REST API in MediaWiki using our routing infrastructure	Engineers develop or convert at least one service to REST in MediaWiki
Outcome 3: Engineers better understand our current architecture and coding standards and where to find them	Engineers can view the WMF production architecture, the exposed APIs and the coding standards in a centralized documentation portal	Ensure this portal exists, is accessible by engineers inside and outside the organization, and is announced on public communication channels
