  1. Human factors, usability engineering, user research of medical devices for product design, root-cause analyses, 510(k) FDA clearance.

  2. Empathy studies of patient/provider interactions to improve preventative health care measures, health care utilization, and follow-up;

Heuristic Evaluations
Business Presentation


Improving Website Usability and Successful Use
We draw on a variety of heuristic models to systematically analyze and improve users' experience with your website or online service. We examine how easy it is to navigate your website, discover essential tabs and links, enter critical information, and complete necessary tasks. We'll provide you with a detailed report that highlights sources of friction, pain points, satisfactions, and opportunities for improvement that will ensure those using your site do so successfully.


Making Sure your Devices are Easy to Use, Safe, and Effective
We conduct formative, summative, and benchmark usability tests for human factors engineering and 510(k) FDA clearance. We help improve your medical devices so they're easy to use and reduce use errors so you can get them to the people who need them without unnecessary and costly delays.
Doctor's Desk
Summative Usability/Validation Tests:​
We will assess risk management measures and uncover use errors, close calls and difficulties to reduce risks and ensure your device receives FDA clearance (510(k)).
  • Ex. Root Cause Analyses, Validation Testing
Formative Usability Tests:
We conduct exploratory user research early in the development stages so you can design a product that resonates with users' mental models, makes sense, and is easy to use. 

With formative usability tests you can better ensure 510(k) FDA clearance and avoid costly, time-consuming mistakes by identify risks and shortcomings early, when they are easy to fix.
Benchmark Tests:
We conduct research with users that compares your device against prescribed standards, goals, or a leading competitor or predecessor.

Make sure your new product outshines the competition.

Lay Caregivers

How We Help

Effective health care requires trust and satisfaction. Medical devices must be safe and easy to use if they are to receive FDA 510(k) clearance and be adopted by users. Web services must be easy to navigate. Patient experiences must foster trust in service providers and the devices they need. When these are absent the probability and severity of harm, frustration and disappointment increases. Manufacturers make devices that go unused and are unsafe, and people cannot access needed services, and may avoid seeking health care all-together, or until it's too late.

TIMBS Consulting works to ensure your users, customers, clients, and patients get the safe, trusting, and satisfactory experience they need and deserve.

With TIMBS, you can ensure:

  • Your medical devices are user friendly, safe to use and receive 510(k) FDA clearance 

  • Your websites are intuitive, easy to navigate and complete necessary tasks

  • Your patients are satisfied with their experience and will seek future health care before it's too late
