Version 3 of the Electronic Discovery Reference Model (EDRM) diagram, has been released by the EDRM standards organisation for the e-discovery market. Originally published in 2006, the framework is a popular tool used by legal professionals and others involved in e-discovery to help clarify processes and expectations among project stakeholders. 

Version 3 of the EDRM diagram offers significant updates, primarily to express the importance of information governance (IG) as a key piece of the electronic discovery process. 

The leftmost item in the model has been renamed "Information Governance" and its shape has been changed from a rectangle to a circle. These edits better align this diagram with EDRM's Information Governance Reference Model (IGRM). The adoption of a circle also is meant to show that every well-managed e-discovery process should start and end with sound information governance.

In addition, the line from Presentation to Information Governance has been widened. This emphasizes that no e-discovery process is fully completed -- no matter at what stage it stops -- until it has been looped back to IG. 

The final update to the diagram is the increased size of the words "VOLUME" and "RELEVANCE" in the bottom corners of the diagram. This change draws greater attention to the two core objectives driving most e-discovery projects. 

The process of updating the diagram began during a group session at the EDRM 2013 Mid-Year Meeting Members agreed that with the increased attention on IG, an update to the popular model was necessary. 

The new (Version 3) EDRM diagram is available free of charge and can be downloaded in a variety of file formats from the EDRM website.
