Product Analytics

Jump to navigation Jump to search

The Wikimedia Foundation's Product Analytics team mainly supports teams within Audiences department, but also supports teams in other parts of the Foundation. The team helps product managers, engineers, and executives make data-informed decisions through:

  • Extracting insights and datasets from the Foundation's data repositories
  • Crafting key performance indicators (KPIs) and other metrics
  • Building dashboards for tracking success and health metrics
  • Design and analysis of experiments (A/B tests)
  • Ad-hoc analyses and machine learning projects
  • Developing tools and software for working with data

The team makes recommendations based on results of analyses, advocates for ethical data practices, and educates on topics around data and statistics.


Each analyst in embedded into one team, which means they participate in the team's day-to-day activities and discussions so that they can provide proactive analysis support. Each analysts are also assigned to additional teams and functional areas, which means they're the primary point of contact for requests from those teams, but generally don't join the team's day-to-day activities.

Depending on the team's capacity, it may also accept requests from others in the Wikimedia Foundation.

The team also reserves "10 percent time" to work on professional development. The team's manager is Kate Zimmerman, Head of Product Analytics, whose role involves prioritizing requests, managing capacity, and professionally developing members of the team.

Task management[edit]

We track our work in the Product-Analytics project on Phabricator. For our definitions of the task priority levels, see the project description.


The Product Analytics team believes that in addition to professional expertise and personal experience, decisions should be supported by data and scientific rigor.
