Six Sigma Expert Witnesses

Six Sigma enters litigation when the quality and efficiency of business processes, or promises made about improving them, become the subject of a dispute. Manufacturers, suppliers, and service providers litigate over defect rates, process capability, and quality obligations embedded in supply and outsourcing agreements. Consulting and transformation engagements generate disputes when promised cost savings or performance improvements fail to materialize. In regulated industries such as medical devices, pharmaceuticals, and aerospace, Six Sigma and related quality methods may also be relevant to whether a company maintained adequate process controls.

A Six Sigma expert helps attorneys evaluate process performance using the statistical and analytical tools on which the methodology relies. The expert can assess process capability, control charts, measurement system analysis, root-cause investigations, and DMAIC project documentation to determine whether a process was capable of meeting specifications and whether quality problems reflected systemic failure or isolated events. In consulting and transformation disputes, the expert can evaluate how savings and improvements were measured and whether reported results were supported by data. That analysis frames liability and causation and provides a disciplined basis for damages tied to defects, rework, or unrealized savings.

Credible Six Sigma testimony comes from practitioners who have led improvement programs and applied statistical tools to real operations. Round Table Group can identify Master Black Belts, quality engineers, and operations executives, including professionals whose careers involved companies such as General Electric, Motorola, and Honeywell, along with academics in industrial engineering and quality management and practitioners holding ASQ Six Sigma certifications. Their combination of statistical rigor and operational experience helps a fact-finder understand what the data show about process performance. Our more than 75,000 expert searches for litigators help us align the industry and process at issue with the right expert. To discuss your matter, contact our team by calling us at (202) 908-4500.

Kinds of Cases We Work On

Round Table Group helps our clients find a wide variety of Six Sigma expert witnesses for cases like:

01

Consulting Firm Sued Over Failed DMAIC Project

A consumer products manufacturer sued its Six Sigma consulting firm after a yearlong DMAIC initiative failed to reduce defect rates on a key production line despite contractual performance targets. We identified experts with experience in Six Sigma project methodology, statistical process control, and manufacturing quality management. The expert found the consulting team had used an inappropriate control chart methodology for the process type, supporting the manufacturer's claim.
02

Black Belt Training Vendor Faces Certification Dispute

A manufacturing conglomerate sued a Six Sigma training provider after discovering that dozens of employees certified as Black Belts had not completed the required capstone projects under the vendor's own standards. We identified experts with experience in quality certification program design, Six Sigma curriculum standards, and corporate training program auditing. The expert's audit of project files confirmed the missing capstone documentation, supporting the conglomerate's refund claim.
03

Defect Reduction Guarantee Shortfall Sparks Litigation

An automotive parts supplier sued its quality-improvement consulting firm for failing to meet a contractually guaranteed defects-per-million-opportunities target within the engagement's specified timeframe. We identified experts with experience in automotive quality standards, statistical process capability analysis, and Six Sigma project management. The expert's capability study showed the consultant's chosen control limits masked ongoing tooling wear, supporting the supplier's claim.
04

Process Improvement Fee Dispute Reaches Arbitration

A logistics company withheld the success-fee portion of a Six Sigma consulting engagement, disputing whether claimed cost savings were attributable to the consultant's recommendations rather than unrelated volume changes. We identified experts with experience in process improvement cost-savings attribution, logistics operations analysis, and consulting fee dispute methodology. The expert's regression analysis isolated the consultant's contribution from seasonal effects, anchoring a reduced but sustained fee award.
05

Certification Body Sued Over Revoked Master Status

A quality consulting firm sued the industry body that revoked its Master Black Belt certification, alleging the process ignored the firm's rebuttal evidence and cost it several corporate contracts. We identified experts with experience in quality certification governance standards, professional credentialing due process, and consulting industry damages. The expert's review of the body's own bylaws found the process had skipped a required review step, supporting the firm's claim.
06

Supplier Quality Audit Dispute Voids Contract

An electronics manufacturer terminated a components supplier after a Six Sigma-based quality audit flagged process capability far below the contractual minimum, prompting the supplier to sue for wrongful termination. We identified experts with experience in process capability index analysis, electronics manufacturing quality audits, and supply contract termination standards. The expert's independent recalculation found the auditor had used an outdated specification limit, undermining the termination basis.
07

M&A Diligence Overstated Target's Quality Metrics

An acquirer sued the sellers of a manufacturing business after post-closing operations revealed the target's reported Six Sigma quality-level metrics had been calculated using a nonstandard, more favorable methodology than disclosed. We identified experts with experience in Six Sigma metric calculation standards, manufacturing due diligence, and M&A representation claims. The expert recalculated the metrics under standard methodology and found a materially lower quality level, supporting the acquirer's claim.
08

ERP Rollout Blamed for Stalled Quality Program

A manufacturer sued its ERP software integrator after a botched implementation disrupted the data feeds underlying its Six Sigma quality dashboards, forcing suspension of an active process-improvement initiative for months. We identified experts with experience in manufacturing ERP systems integration, quality data infrastructure, and process improvement program management. The expert traced the disruption to a misconfigured, untested data mapping, supporting the manufacturer's damages claim.
09

Failed Process Fix Triggers Production Line Shutdown

A packaging company sued a Six Sigma consulting firm after implementing its recommended process change caused an unforeseen line shutdown, alleging the consultant failed to adequately pilot the change before full rollout. We identified experts with experience in process change validation methodology, packaging line engineering, and consulting standard-of-care review. The expert found the consultant had skipped the pilot-phase step required by its own methodology, supporting the negligence claim.
10

Methodology Licensing Dispute Divides Consulting Rivals

A boutique quality consultancy sued a larger rival firm for using its proprietary Six Sigma training curriculum and toolkits after a licensing agreement between the two firms expired. We identified experts with experience in intellectual property in training curricula, quality consulting industry practices, and licensing damages calculation. The expert's side-by-side comparison of course materials found substantial unauthorized copying, supporting the infringement claim.
