It’s a bad day when you start eDiscovery on a matter you think is going to be a breeze, and instead you end up knee deep in tangled email threads, 100,000 Slack messages, and convoluted meeting minutes. Many legal teams don’t find out how big a matter really is until they are already buried in it. A single public records request can return more than 200,000 documents. A single internal investigation can eat a paralegal’s month before anyone opens a file. But when you have a solid early case assessment strategy, you can flip that uncertainty into a plan, getting a clear sense of the size, cost, and risk of a matter before you commit real budget to it.

Early case assessment by definition

Early case assessment, or ECA, is the process of quickly scoping a legal matter’s data, cost, and risk before full document review begins. Legal teams use it to estimate custodians, data volume, and reviewer hours early enough to make a real call: settle, negotiate, litigate, or decline.

Invest in ECA upfront and save in the long run

For years, the default move was to collect first and ask questions later. Full collection, then full review, then a bill leaving you full of regrets. This blind approach was always risky, but it’s worse now. Requesters and opposing parties are increasingly using generative AI to draft sprawling “any and all documents” requests that cast a wide net, and data sets have ballooned into hundreds of thousands of documents.

As the Electronic Discovery Reference Model (EDRM) has noted, teams that scope a matter’s likely cost and exposure before committing to full review consistently spend less than teams that collect first and ask questions later.

Courts expect legal teams to have a real handle on this. Federal Rule of Civil Procedure 26(b)(1) ties the scope of discovery to proportionality, weighing the burden and expense of discovery against the needs of the case. A team that shows up with real custodian counts and document volume is in a stronger position to negotiate scope, timing, or cost than one that’s still guessing. So, teams need to turn away from guesswork towards strategy, a pivot early case assessment facilitates.

How to conduct early case assessments

Follow these steps at the start of a matter to gain early insights:

• Identify custodians and data sources. Figure out who touched the matter and where their data lives. Is it in email? Slack? Teams? Shared drives? A mix of all four?
• Set a timeframe and draft search terms. Narrow the window that matters and test keyword searches before running them at full scale.
• Cull and dedupe before anyone opens a document. Take the time to process and organize your data set before starting search and review. Strip out exact duplicates and collapse repetitive email threads, then you avoid reviewing the same content twice.
• Pull document and page counts. Turn “how big is this?” from a guess into a number a reviewer or budget owner can derive real meaning from. If you know that eDiscovery on this matter means reviewing 20,000 pages of email documents, you have a clearer sense of how much of your time you need to block off to do the review, and in turn how much this review costs.
• Use the numbers to decide the next move. When you have data, you can be strategic with how you move forward, whether that means negotiating scope, requesting an extension, settling, or moving into full review with a clear budget set.

Common obstacles with ECA

ECA only pays off if the output actually changes the plan. When ECA is just run as a formality, when you just pull a number and then proceed exactly as you would have, you don’t get the payoff of this strategy. Another roadblock is incomplete ECA: when you scope the predictable data and miss more complex types like Slack, Teams, or AI-generated content, you might run into unwelcome surprises during review. Another trap is skipping deduplication, since uncut, duplicate-heavy counts overstate the real review burden and can scare a team into budgeting for a matter twice the size it actually is.

ECA in Real Life

Fairfax County’s information security team runs a version of this on nearly every public records request it handles. After deduplicating incoming Microsoft 365 exports with an inclusive-email tool that collapses repetitive threads, the team pulls updated document, page, and spreadsheet counts before review starts. That gives reviewers a clear picture of what they’re about to open, and gives the county’s FOIA office a real basis for the cost estimates it sends to requesters. That step is part of why Fairfax can keep up with a 200% increase in annual request volume for email records.

An ECA checklist

• Custodians and data sources identified and confirmed
• Date range and initial keyword terms drafted and test-searched
• Duplicate and near-duplicate content culled before review starts
• Document, page, and data volume counts pulled and shared
• Reviewer hours and cost estimated from real counts, not guesses
• Scope, budget, or strategy decision made and documented

What ECA buys a legal team

• Real numbers instead of guesses. Custodian counts and document volume replace gut-feel estimates that tend to be wrong in one direction: too low.
• Leverage in negotiation. A team that can point to actual scope and cost has a stronger footing in a Rule 26(f) conference or a settlement conversation.
• Time back. You stop spending weeks reviewing documents a matter never actually obligated you to touch.
• A defensible paper trail. Documented scoping decisions hold up if a party or court later questions how you got to your production.

Common questions about early case assessment

What is early case assessment (ECA) in eDiscovery?

ECA is the process of scoping a legal matter’s data volume, cost, and risk before full document review begins, so legal teams can make an informed decision about how to proceed.

How is ECA different from full document review?

ECA is a scoping step. It estimates volume and exposure. Full review is the actual document-by-document work of finding responsive, privileged, or exempt material.

What data do you need before running ECA?

At minimum, a list of likely custodians, their data sources, and a rough date range. From there, you can collect, dedupe, and search before committing to full review.

Can ECA help decide whether to settle a case?

Yes. Knowing real exposure and cost early gives legal and business stakeholders the information they need to weigh settlement against litigation.

How long does early case assessment usually take?

It varies by matter size, but the point of ECA is speed: most teams can collect, dedupe, and pull volume counts in hours or days, not weeks.

Does ECA replace a litigation hold?

No. A litigation hold preserves data as soon as a duty to preserve arises. ECA happens after preservation, to help a team understand what it’s now responsible for reviewing.

Early case assessment turns “we think this could be big” into a number a legal team can actually plan around, before budget and time are already spent.
