Collaborative editing

Collaborative editing is the practice of groups producing works together through individual contributions. Effective choices in group awareness, participation, and coordination are critical to successful collaborative writing outcomes. Most usually it is applied to textual documents or programmatic source code. Such asynchronous (non-simultaneous) contributions are very efficient in time, as group members need not assemble in order to work together. Generally, managing such work requires software; the most common tools for editing documents are wikis, and those for programming, version control systems. Most word processors are also capable of recording changes; this allows editors to work on the same document while automatically clearly labeling who contributed what changes.

Wikipedia is an example of a collaborative editing project on a large scale.
