The EDRM model is a conceptual view of the e-discovery process. Phases do not necessarily flow in the order presented.
The EDRM model is an iterative process, where certain steps may be repeated numerous times, in order to identify a more precise set of results.
An eDiscovery process may also require revert back to earlier steps, in order to further refine the data as new information comes to light.

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.
