An Am Law 100 firm engaged Sandline Global to manage a large-scale responsiveness review under a tight production deadline. Leveraging Sandline’s attorney-led review model, and Sandline’s Everlaw TAR 2.0 expertise, the team was able to dramatically reduce review volume and cost while maintaining defensibility and high recall.
The client faced a complex, high-volume review of over 240,000 documents under a tight deadline. The team needed to ensure maximum recall and defensibility while reducing cost and risk. Past experiences with other service providers had left them frustrated by inefficiencies and unpredictable quality: the classic service provider “rollercoaster.”
They turned to Sandline for a different kind of partnership: one grounded in accountability, collaboration, and a commitment to owning the outcome and meeting deadlines.
Sandline’s approach was rooted in its core philosophy: We obsess over quality, so our clients don’t have to. Rather than simply deploying technology, Sandline partnered closely with the client’s team to design a CAL/TAR 2.0 workflow tailored to the matter’s priorities. Sandline also staffed a team of experienced Everlaw licensed attorneys to further drive efficiencies.
Key steps included:
- Collaborative Strategy: Sandline worked with the client to establish parameters that favored a conservative, “catch-all” discovery posture.
- Model Training & Validation: The TAR model reached stability at rank 59, indicating no meaningful gains in recall beyond that point—allowing the team to confidently set an optimal cutoff.
- Defensibility Testing: A post-model elusion test validated the cutoff’s accuracy, confirming a statistically defensible elusion rate of 2.34% at a 95% confidence level.
Proactive Communication: Continuous performance monitoring and transparent reporting gave the client full confidence in each decision point.
Through this data-driven approach guided by a team of tenacious problem solvers, Sandline delivered quantifiable impact:
| Metric | Result |
| Full Review Universe | 241,411 documents |
| Documents Excluded from Review | 144,011 |
| Manual Review Reduction | ~60% |
| Review Hours Saved | 2,618 hours |
| Estimated Cost Savings | $157,000+ |
| Recall | 90.9% |
| Precision (95% CI) | 36.7% – 46.6% |
| Elusion Rate (95% Confidence) | 2.34% |
The validated model enabled the team to identify responsive material efficiently, achieve the production deadline, and substantially reduce review burden—all while maintaining statistical rigor and defensibility.
By trusting Sandline’s predictive coding strategy and embracing a collaborative workflow, the client achieved high recall, measurable savings, and a defensible review outcome.
In the end, this wasn’t just about saving $157,000, it was about achieving consistency, control, and confidence in a process that too often feels overwhelming.
At Sandline, we don’t just deliver outcomes. We own them.
