This page documents methods to measure whether an individual wiki action (edit) contributed productively to a wiki's "product". For a more nuanced discussion, see editor productivity.
An edit is productive if it changes an article (i.e. namespace zero) and is not quickly reverted by another editor.
Revert detection is a nuanced topic. Reverts in Wikipedia are commonly detected by identity due to the fact that the vast majority of reverts can be captured this way and it is relatively fast to compute.
When identifying which revisions were reverted, it's necessary to wait a reasonable amount of time another editor to perform a revert (or not). In the English Wikipedia, most revisions that will ever be reverted are reverted within minutes of the original edit, and nearly all are reverted within 24-48 hours.
A revision to an article is considered productive if it is not identity reverted within 24 hours of when it was originally saved.
Prior to this standardized definition, the notion of a productive edit has been used to identify the user class of productive new editors by identifying those newcomers who make at least one productive edit in their first day or week of editing.
