2. The eDiscovery Process: A Detailed Examination

The eDiscovery process is typically structured into several distinct stages, each requiring specific expertise and technologies. These stages are commonly defined as:

2.1. Identification

The identification stage involves locating potential sources of relevant ESI. This requires a thorough understanding of the case or investigation, including the key issues, relevant time periods, and custodians (individuals who may possess relevant information). Identification can be a particularly challenging task due to the distributed nature of data across various systems and locations, including on-premise servers, cloud storage, mobile devices, and legacy systems. Advanced techniques, such as custodian interviews, data mapping, and keyword searching, are often employed to effectively identify potential data sources. A defensible data map outlining the location and types of data stored is crucial for demonstrating a reasonable effort to identify relevant information.

2.2. Preservation

Once potential sources of ESI have been identified, the preservation stage focuses on ensuring that the data is protected from alteration, deletion, or destruction. This is a critical step, as failure to preserve potentially relevant information can result in sanctions for spoliation of evidence. Preservation methods may include legal holds, data archiving, and imaging of hard drives or other storage devices. A legal hold is a formal notification to custodians instructing them to preserve potentially relevant information. The legal hold process should be well-documented and regularly monitored to ensure compliance. Increasingly, organizations are employing automated preservation tools that can automatically place legal holds on relevant data sources and prevent deletion or modification.

2.3. Collection

The collection stage involves gathering relevant ESI from identified sources. This process must be conducted in a forensically sound manner to ensure the integrity and authenticity of the collected data. Collection methods may include imaging hard drives, extracting data from email servers, and copying files from shared drives. It’s essential to use specialized tools and techniques to preserve metadata, which provides valuable information about the creation, modification, and access history of electronic documents. Data should be collected with minimal disruption to business operations. A common approach is to use targeted collections based on specific criteria, such as keywords, date ranges, and custodians, rather than collecting entire data repositories.

2.4. Processing

Collected ESI often requires processing to prepare it for review. This stage typically involves de-duplication (removing duplicate files), data extraction (extracting text and metadata from documents), and format conversion (converting files to a reviewable format, such as TIFF or PDF). Processing can be computationally intensive, especially when dealing with large volumes of data or complex file types. Many eDiscovery platforms offer automated processing capabilities that can significantly reduce the time and cost associated with this stage. The processing stage also often includes Optical Character Recognition (OCR) to convert scanned images into searchable text.

2.5. Review

The review stage is arguably the most time-consuming and expensive aspect of the eDiscovery process. It involves examining the processed ESI to identify documents that are relevant to the case or investigation. Reviewers typically use eDiscovery platforms to search, filter, and tag documents based on their relevance, privilege, and other criteria. Technology-assisted review (TAR), also known as predictive coding, is increasingly being used to accelerate the review process. TAR uses machine learning algorithms to identify relevant documents based on a training set of documents reviewed by human experts. The use of TAR can significantly reduce the number of documents that need to be manually reviewed, thereby saving time and money.

2.6. Analysis

The analysis stage involves examining the reviewed documents to identify patterns, trends, and key information that can support the case or investigation. This stage may involve using data analytics tools to visualize data, identify relationships between custodians, and uncover hidden connections. Analysis can also involve creating timelines, identifying key documents, and preparing summaries of the evidence. This stage requires a deep understanding of the case and the ability to synthesize information from multiple sources.

2.7. Production

The production stage involves providing the relevant ESI to opposing counsel or regulatory authorities in a specified format. The production format is typically agreed upon by the parties or mandated by the court. Common production formats include TIFF, PDF, and native file formats. It is essential to ensure that the produced data is complete, accurate, and compliant with applicable production requirements. This includes redacting privileged or confidential information and Bates stamping documents for identification purposes. A thorough quality control process is necessary to ensure that the production is accurate and defensible.
