The Professional's Guide to eDiscovery Production

The process of legal eDiscovery involves identifying, preserving, and producing digital evidence in the context of litigation or regulatory proceedings. As the volume and complexity of electronically stored information (ESI) continue to grow at an unprecedented rate, eDiscovery, particularly the production stage, has become one of the most strategically important functions in modern legal practice.

The global eDiscovery market already tops $15 billion and is forecast to expand at roughly 8–11% annually, driven largely by AI-enabled review and analytics. For legal teams operating under tighter deadlines and budgets, understanding the production process and how to execute it efficiently is no longer optional.

This guide breaks down how eDiscovery works, what happens during production, and the best practices that leading legal teams are using today.

Why Do Legal Teams Engage in eDiscovery?

Legal eDiscovery is part of the pretrial discovery process. Before proceeding to trial, opposing parties exchange evidence to expedite proceedings and prevent either side from introducing surprise evidence in court. Discovery covers tangible evidence; eDiscovery covers digital evidence.

Both mechanisms serve the same underlying purpose: ensuring a fair, efficient, and transparent trial process.

What Is ESI?

The term "eDiscovery" applies exclusively to electronically stored information (ESI). This encompasses emails, cloud-stored files, databases, text messages, and locally stored data on computers and mobile devices.

The scope of ESI has expanded considerably in recent years. A growing consensus has emerged on the handling of short messages such as Slack or Teams chats, text messages, and other mobile data, as these modern forms of communication are increasingly pertinent in legal disputes. 

Legal teams must now be prepared to collect and produce data from a wide range of platforms and device types, not just traditional email and document repositories.

How eDiscovery Works

Most organizations follow the Electronic Discovery Reference Model (EDRM), a widely recognized framework that provides structured guidance across the full eDiscovery lifecycle. The EDRM consists of nine stages, each with specific objectives.

AI now strengthens every stage of the EDRM workflow, from identification through production, transforming how teams find, preserve, and present evidence. The stages themselves, however, remain a reliable foundation for any eDiscovery strategy.

1. Information Governance

Information governance is a foundational step focused on establishing policies and controls over data before any dispute arises. The goal is to ensure ESI is organized, accessible, and defensibly managed, reducing the complexity and cost of eDiscovery when it becomes necessary.

2. Identification

Identification involves locating potential ESI sources and determining their scope, breadth, and depth. Today, this step must account for data stored across cloud platforms, collaboration tools, mobile devices, and third-party applications, not just on-premise servers or individual workstations.

3. Preservation

Preservation protects ESI from inappropriate modification or destruction once litigation is reasonably anticipated. This step is foundational to defensibility; failures at the preservation stage remain one of the most common sources of sanctions and adverse inferences in modern litigation.

4. Collection

Collection involves gathering ESI for further examination and sharing. The complexity of this step has grown significantly. Collection's share of eDiscovery expenditures has nearly tripled, rising from 8% in 2012 to 16% in 2024, reflecting the increasing complexity of data environments and the need for advanced tools to handle diverse sources like cloud platforms, IoT, and multimedia.

5. Processing

Processing reduces the overall volume of ESI and converts it into a form suitable for analysis and review. This stage involves deduplication, filtering, and normalization, which has increased its strategic importance considerably. 

What was once a mechanical volume-reduction task has transformed into a strategic inflection point for downstream success, with the proliferation of social media, chat platforms, and collaborative workspaces demanding more sophisticated parsing and normalization.

6. Review

Review involves evaluating ESI for relevance and privilege. This has historically been the most expensive phase of eDiscovery. In 2012, review accounted for 73% of eDiscovery costs. By 2024, that share had dropped to 64%, with projections indicating a further decline to 52% by 2029, driven by efficiency gains from generative AI, technology-assisted review (TAR), and predictive coding.

7. Analysis

Analysis requires exploring ESI for content, context, and patterns relevant to the legal matter. Modern AI-powered tools can visualize communication patterns, changes in sentiment, and emerging narratives that plug into traditional review and production workflows. This makes it possible to surface key facts and timelines that would be difficult to detect through manual review alone.

8. Production

Production entails delivering ESI to stakeholders in a mutually agreed-upon format once review and analysis are complete. This is examined in detail in the section below.

9. Presentation

Presentation is typically the final stage of eDiscovery. At this point, a party presents ESI during a trial, hearing, or deposition to support their case.

What is eDiscovery Production?

Production refers to the process of preparing ESI and delivering it in a usable, legally compliant format for the opposing party or the court. Effective production makes data accessible and comprehensible, removes non-responsive or privileged content, and ensures that what is delivered conforms to agreed-upon technical specifications.

Production also serves a cost-control function. By rigorously culling ESI before production, legal teams avoid delivering unnecessary data, which reduces review burden for both sides and minimizes the risk of inadvertent disclosure of privileged material.

The EDRM recommends the following steps during the production stage.

1. Confirm Forms of Production

Before any data is prepared for delivery, confirm the agreed-upon production format with opposing counsel. This typically happens during the meet-and-confer session and should address file format, metadata fields, document numbering conventions, and delivery method.

2. Data Analysis

Data analysis involves reviewing your document population and determining the most appropriate production format for each file type. Common production forms include:

• Native: Files delivered in their original format, preserving full metadata and structure. Generally preferred for spreadsheets, presentations, and collaboration platform exports.
• Near-native: Files extracted into a searchable format that approximates the original, often used when the native format is not agreed upon or appropriate.
• Image (PDF or TIFF): Used when parties require a static, paginated representation of documents, often with redactions applied.
• Paper: Reserved for situations where a physical format is specifically required, though this is increasingly rare in modern practice.

3. Identify Production Requirements

Determine the specific data types, custodians, and date ranges within scope, and confirm that any privilege review, redaction, or metadata scrubbing has been completed before files enter the production queue.

4. Prepare Files

Data preparation involves applying Bates numbering for document identification, generating load files, applying any required redactions, and ensuring the production set aligns fully with the specifications established during the meet-and-confer session.

5. Deliver to Stakeholders

The final step is the secure delivery of the production set. While physical media such as hard drives remain an option, legal teams increasingly use secure digital repositories and cloud-based portals for faster, more auditable delivery.

Best Practices for eDiscovery Production

The production stage is one of the most consequential phases of eDiscovery; errors here can have significant legal and financial implications. The following practices reflect what leading legal teams are doing today.

Cull Aggressively Before Production

Producing more data than necessary drives up costs for both parties and increases exposure risk. Apply deduplication, date filtering, custodian scoping, and relevance criteria rigorously before finalizing your production set. The goal is a targeted, defensible dataset, not a comprehensive data dump.

Leverage AI-Assisted Review to Improve Speed and Accuracy

AI is transforming the way law firms and legal service providers approach eDiscovery by automating repetitive tasks such as identifying relevant documents and applying predictive coding, speeding up the document review process while improving accuracy and reducing expenses. 

For large or complex matters, technology-assisted review combined with generative AI summarization can dramatically reduce the time it takes to get from raw ESI to a production-ready document set.

Hybrid approaches that combine generative AI with established TAR workflows are gaining traction, offering a balanced path for firms seeking to reduce costs and improve efficiency while managing risk.

Work Closely With IT and Data Specialists

The technical complexity of modern data environments means that legal teams cannot operate in isolation. Data analysts and IT professionals play a critical role in collecting ESI from disparate systems, normalizing data formats, and ensuring the integrity of the production set. Establishing clear lines of communication between legal and technical teams from the outset of any matter reduces errors and delays downstream.

Agree on Format Before the Matter Progresses

Disputes over production format mid-matter are disruptive and costly. Address format requirements during the meet-and-confer session, before significant work has been done under a format assumption that may need to change. Agreeing early on whether native, image, or near-native production is appropriate gives both parties time to prepare and reduces friction throughout the process.

Keep Pace With the Timeline

Courts expect eDiscovery to move efficiently, and delays in production can result in sanctions, adverse inferences, or reputational damage with the court. Establish internal milestones for each production phase and monitor progress against them regularly. For very large matters, consider phased productions to demonstrate good faith and maintain momentum.
