A discussion of forensic investigation case studies from both technical and legal perspectives
In " Introduction to Discovery (6/7): The Key to Controlling Costs is to Check Estimates (Part 1)," we have explained the cost breakdown of each step in the process in comparison with the estimates.
Please consider that the quotes given as examples are from conscientious vendors. Only a few vendors will provide such a detailed estimate, and most will have only a few items in the estimate and only a "complete set of work" amount.
In addition, many vendors will present only the unit price without stating "unit price x estimated volume" for the calculation of the amount.
It is important to understand the "tricks" often used by these vendors.
If the estimate does not indicate the expected quantity, the vendor is simply chosen based on a comparison of unit prices.
If price is the only consideration, it is reasonable to choose the cheaper one, but what matters is the accuracy of the estimate.
The series of processes from (1) to (7) listed in " Introduction to Discovery (6/7): The Key to Controlling Costs is in the Estimate Check (Part 1) " are all interconnected. Therefore, the quality of the initial process work, such as collection, process, and hosting, directly affects the overall review quality. Insufficient refinement will result in an increase in the number of files to be reviewed and an increase in translation work.
For example, if the process process supports Japanese character codes and is supported by bilingual experts as shown in the figure, the number of files to be reviewed can be reduced by about two-fifths (from 100 GB to 40 GB). On the other hand, if the process work is not supported only in Unicode or if there are concerns about the technical capabilities of the processors, the cost will increase due to garbled characters or translation required after the process or at the keyword search stage, and the target files for review cannot be narrowed down.
In other words, if the technology and quality in the process work is inferior, the cost of review will further increase.
From a cost management perspective, it is more important to reduce review costs than to reduce process costs.
It is estimated that review costs account for roughly 70% of total discovery costs, with the remaining 30% coming from collection, hosting, and processing. No matter how much you reduce this 30%, if the remaining 70% increases, the overall cost will be rather high.
Why the difference in cost?
Point If only some character codes are supported, process costs will increase due to the need for garbled characters and translations in keyword searches and other analyses. Also, since data volume cannot be reduced, uploading costs will also increase.
