Directions to an e-discovery solution: Keep collection and processing on-premises

Organizations should consider all steps in the e-discovery process and tailor a solution to fit their needs and infrastructure

Part one of this series introduced the following best-practice strategy for deploying e-discovery software solutions: on-premises software for the left side of the Electronic Discovery Reference Model (EDRM), and cloud-based technology for the right-side processes. In part two, we’ll talk about how this model impacts collection and preservation, and processing.

On-premises left-hand side means using behind-the-firewall technology to build an organization’s customized process for the following: pre-collection analytics, issuing legal hold notices, collecting and preserving electronically stored information (ESI), processing ESI and first-pass review of ESI. Part I discussed the reasons for using on-premises software for the pre-collection analytics and legal hold. Now, we’re taking a look at key issues for collection/preservation and processing.


Processing ESI, i.e., de-duplicating and further culling data, has traditionally been the provenance of review and vendor-hosted solutions. We often think of processing as a specific step in the linear process of e-discovery that sits between the collection of ESI and review.
