Why eDiscovery processing matters?

Legal teams often focus on two bookends of discovery: collecting data and reviewing documents. The step in between, eDiscovery processing, is where much of the cost, risk, and defensibility of discovery is determined.

Processing transforms large, unstructured datasets (emails, chats, mobile data, cloud files) into a lean, defensible, review-ready collection. Without it, teams face higher review costs, missed evidence, or even court sanctions. Done correctly, processing is not just an IT task, it is a legal safeguard.

In today’s digital-first disputes, courts expect ESI (electronically stored information) to be complete, searchable, and defensible. Proper eDiscovery workflow management ensures evidence is preserved, costs are contained, and productions withstand scrutiny.

Breaking down the eDiscovery workflow

Here is how raw data becomes usable evidence:

• Ingestion and Normalization – Collected data is unpacked, standardized, and assigned unique identifiers. Time zones are aligned so emails and chats read in proper sequence.
• Filtering and Culling – System files and irrelevant material are defensibly removed (DeNISTing). Custodians, date ranges, and keywords reduce the dataset.
• Deduplication – Duplicate documents are eliminated globally, ensuring each unique record is reviewed once. This step directly cuts review costs.
• Text Extraction and OCR – All content is indexed for search, with scanned images converted into searchable text
• Audit Trail Creation – Every action is logged, producing reports that stand up to court challenges.
• Exception Handling – Corrupted or encrypted files are identified, documented, and addressed before they can stall review.
• Export and Review Prep – The reduced dataset is securely prepared for legal review platforms.

Common pitfalls in eDiscovery processing

Even experienced teams can encounter costly mistakes if processing is mishandled:

• Corrupted files discovered too late delay productions.
• Time-zone misalignments create inaccurate timelines.
• Over- or under-collection leads to spoliation risk or inflated costs.
• Missed privilege checks result in accidental disclosures.
  
  

The most effective safeguard is a combination of advanced automation, structured eDiscovery workflows, and expert human oversight.
