Why you need Usability Engineering

Two reasons, quite simply.

Firstly, by applying usability engineering early and often in the development process, you quickly and economically uncover any issues and use risks about your medical device. Then, the design can be refined to improve safety, mitigate risk, minimise development costs, comply with regulatory requirements and maximise market adoption potential.

Secondly, to legally market your device in US, AU, EU or APAC regions, your regulatory submission requires evidence of usability engineering.

Our team specialises in compliance to FDA guidances and IEC62366; internationally recognised human factors standards in the medical device industry. If you’re looking for additional project resources, expert advice on your human factors regulatory submission, or someone to manage and lead your usability engineering efforts, Sento’s team of expert consultants are here to help.

Let’s setup an introductory call. There is no medical device that doesn’t benefit from good usability.

Some of Our Clients

Sento’s contribution to our patient-centric solution has been invaluable. Carla in particular has an impressive way of uncovering our user’s needs – she empathizes with the user, and also delivered technically for our implementation team. 

Ajit Ravindran
CEO, Lenexa Medical

We already know why human factors are important in product development and improving patient outcomes. We were shocked by the commercial value of the work Sento did with us. It has allowed us to effortlessly accelerate commercial discussions and alleviate risks that investors perceive of a start-up.

Jacqui Savage
Chief Product Officer, CYBAN

Sento was very professional in their approach to understanding the client’s needs and providing an end to end service. Would definitely use Sento again as the service provided was exceptional.

John Nguyen
Regulatory Affairs Manager, AnteoTech

Nirtek engaged Sento in a number of capacities, including Voice of Customer studies, R&D Program Management, and primarily as our expert Human Factors Engineering provider. Having worked with the Sento team for the past 2 years, the value they’ve added has been significant. Their lean and highly collaborative approach to Human Factors, coupled with strong leadership and an ability to build, support and integrate seamlessly into our broader team has been a major contributor to the successful progress Nirtek has made. We’re thrilled to have Sento as a key partner in our development and commercialisation journey.

Matthew Hoskin
CEO & MD NIRTEK

We needed to understand the regulatory pathway for one of our products, and Sento came highly recommended as the usability experts. It’s clear why. They understand product development and regulatory processes, as well as the commercial realities of a start-up, giving us exactly what we needed in a streamlined way.

Dr Andrew Tucker, endorsed by Cameron van den Dungen
R&D Director, CEO Sleeptite

We knew we needed to assess our product’s usability, and given how highly everyone spoke about Sento, we were confident in their expertise. What I wasn’t expecting was for them to identify and proactively solve problems we didn’t know existed. The results of the engagement gave us the confidence to focus our efforts on where they were most needed. It was a great experience working with a partner who we felt was totally invested in getting the best result for us and our users.
