The EDRM – the Electronic Discovery Reference Model – is that ubiquitous diagram invented by George Socha and Tom Gelbmann which illustrates the stages of a typical electronic discovery / disclosure process. The website is also full of information designed to help those engaged in eDiscovery, including a glossary of terms, suggested standards, and a mass of material on metrics, search and testing, as well as another well-known model the Information Governance Reference Model or IGRM.
EDRM now brings us a similar model for computer assisted review, the Computer Assisted Review Reference Model (CARRM). Computer Assisted Review is, of course, but one of the names given to this type of technology algorithms, processes and workflows; others include Technology Assisted Review and Predictive Coding. Whilst I favour Predictive Coding, there is something soothing about an arrangement of letters which, used as an acronym rather than just a set of letters, makes us think of that wartime notice – Keep CARRM and Carry On.
For immediate purposes, I do no more than point you to it.
No illustrative model can properly show the proportions of time and cost spent on any one stage – as George Socha is fond of pointing out, if review was shown at its full size in the EDRM relative to other stages, you would need a very large screen or piece of paper to show them all. Much the same is true of the early stages of a technology assisted review exercise as shown in the new CARRM.
I saw a tweet yesterday which included a quotation from Abraham Lincoln which is new to me: “Give me six hours to chop down a tree and I will spend four of them sharpening the axe”. This idea provides a good parallel for computer-assisted review, with the hard work lying in the initial stages of designing a protocol and educating the reviewer. These are legal and human activities – anyone who thinks that you throw data into a black box and go off for tea while waiting for the results will undoubtedly get it wrong.
Incidentally, the EDRM site also includes a link to the Grossman-Cormack TAR Glossary of Technology Assisted Review
