Why This Matters

A technically sound investigation only helps a case if it can be communicated credibly under oath. Written opinions have to meet evidentiary standards, and testimony has to hold up against aggressive cross-examination on both the underlying technical findings and the methodology used to reach them.

How Engagement Typically Works

Engagement typically begins with a technical review of the case materials, followed by investigation and analysis, a written expert report, and then deposition and, where the case proceeds, trial testimony. Rebuttal work follows the same structure in response to an opposing expert’s report.

When to Engage

Engaging early allows expert testimony to be built on a complete technical record rather than reconstructed after key discovery deadlines have passed.
