The productivity of an editor refers to how much the editor contributes to the product of a Wikimedia project. For example, in Wikipedia, the product generally refers to encyclopedia content, but other Wikimedia projects (e.g. commons) may consider other type of contributions to be "productive" (e.g. uploads).
Several means of measuring an editor's productivity exist. These measure tend to represent a combination of measures of both quantity and quality of user contributions.
- An approach to measuring the overall productivity of Wikipedia as an "industry", with aggregate measures of capital and labor inputs, and aggregate output e.g. by pages shown, has been proposed here. It would use a "multifactor productivity" concept.
-  shows that, while reverted editors tend to be less engaged, their overall productivity (based on measures of content persistence) of editors who remain tends to improve enough to make up for the lower level of engagement.
-  shows evidence that moving draft articles out of the view of readers reduces the productivity (based on the rate at which surviving new articles are created) of new article creators.
