Validation & Compliance
When it’s time to prove safe, effective use, we bring structure, senior judgement and calm delivery. Our programmes are built around real users, real tasks and realistic environments—then documented to the standard regulators expect.
Summative testing
Regulatory strategy
Human Factors documentation
Ethics review & IRB
MDR remediation and legacy file upgrades
Market acceptance
Test with rigour.
Comply with confidence.
Evidence that stands up to scrutiny.
Bringing a medical product to market is complex, costly, and full of unknowns. We help reduce that risk by turning regulatory theory into practical action—so you stay compliant without losing momentum.
A successful submission isn’t just about ticking boxes; it’s about building robust evidence and weaving it into a clear, credible story that regulators can follow with confidence. That’s why we advocate getting involved early—so we can plan strategically, gather the right evidence at the right time, and prevent usability issues long before validation testing.

How we help you acheive your goals
Validation/Summative testing
Evidence that stands up to scrutiny.
We design and run validation (summative) studies that demonstrate intended users can use the product safely and effectively in the intended environment, with no observed patterns of unacceptable/serious use error. Protocols, moderation and analysis are proportionate to device risk and aligned with FDA/MDR expectations.
Regulatory Strategy
Reduce risk. Accelerate approval.
We build pragmatic HFE strategies that connect formative evidence, risk controls, and labelling to a credible submission narrative. Our team has first‑hand experience with FDA interactions and large‑scale MDR programmes, so we anticipate the questions and shape the plan to answer them.
Human Factors Documentation
Robust, traceable Usability Engineering Files.
We author and remediate the Usability/HFE file so reviewers can follow a clear line from hazards to controls to evidence—covering intended use specifications, post market reviews, UI specifications, validation plans, use related risk analyses, critical task lists and threshold analyses. We also compile the HFE/Usability Engineering File Summary Report for submission in either the US, Europe, or both.
Ethics Reviews & IRB
Ethical approvals, without the friction.
For US studies, we prepare IRB submissions; in the UK and Europe, we prepare and work with ethics committees. We produce consent forms, participant materials and study designs that manage participant risks, streamlining approvals without compromising timelines.
MDR Remediation & Legacy File Upgrades
Bring legacy portfolios up to today’s bar.
We review existing files against IEC 62366‑1/ISO 14971, close usability gaps, and document critical information for safety—ready for audits and submissions. Our team has supported enterprise‑scale MDR remediation across hundreds of product lines.
Market Acceptance
Close the loop—sustain confidence pre and post‑launch.
We run market acceptance trials for marketing teams who need data pre-launch. Post-launch, we train customer service teams to collect data that helps to identify root causes. We review complaint trends and conduct hands-on research to ensure that real‑world data informs ongoing product support and improvements.
