EDRM Model

The EDRM diagram represents a conceptual view of the e-discovery process, not a literal, linear or waterfall model. One may engage in some but not all of the steps outlined in the diagram, or one may elect to carry out the steps in a different order than shown here.

The diagram also portrays an iterative process. One might repeat the same step numerous times, honing in on a more precise set of results. One might also cycle back to earlier steps, refining one’s approach as a better understanding of the data emerges or as the nature of the matter changes.

The diagram is intended as a basis for discussion and analysis, not as a prescription for the one and only right way to approach e-discovery.

Below are summary explanations of each EDRM stage.

Information Governance – Getting your electronic house in order to mitigate risk & expenses should e-discovery become an issue, from initial creation of ESI (electronically stored information) through its final disposition.

Identification – Locating potential sources of ESI & determining its scope, breadth & depth.

Preservation – Ensuring that ESI is protected against inappropriate alteration or destruction.

Collection – Gathering ESI for further use in the e-discovery process (processing, review, etc.).

Processing – Reducing the volume of ESI and converting it, if necessary, to forms more suitable for review & analysis.

Review – Evaluating ESI for relevance & privilege.

Analysis – Evaluating ESI for content & context, including key patterns, topics, people & discussion.

Production – Delivering ESI to others in appropriate forms & using appropriate delivery mechanisms.

Presentation – Displaying ESI before audiences (at depositions, hearings, trials, etc.), especially in native & near-native forms, to elicit further information, validate existing facts or positions, or persuade an audience.
