We are usability and UX experts

We specialize in complex systems and critical contexts. In such cases usability mistakes, misunderstandings, or unexpected interactions between technology and people can cause system failures, major damage, or even danger to life. Disaster management, Healthcare, Large-scale IoT, Emerging technologies, and Government and civic engagement are only some of the fields we apply our experience and knowledge to.

Our large spectrum of knowledge and experience allows us to choose the methods that are best for each specific client and case, thus giving you the highest return on your usability investment. We work closely with your managers, product developers, and support team, bringing in knowledge and efficiency that will continue long after our work is done.

Fraunhofer-certified Usability Engineers

We are certified as Usability Engineers by the Fraunhofer FIT Institute, one of the leading Usability training and certification agencies in Germany. The Fraunhofer certification is famous for its strict criteria and high professional standards.

IREB Certified Requirements Engineers

Good user requirements stand at the foundation of successful product development. We have both the experience and the certification to do requirements correctly.

Certified Professionals for Medical Software

Scrum, Scrum-But, and a wide range of project management approaches

No matter whether you use agile, iterative, or traditional development approaches, we know them and will fit seamlessly with your team. We are not religious on any approach (but we are religious in delivering excellent quality with any of them!)

ISO 9241 Usability Engineering & ISO 25062 Reporting

The word “Usability” has been used and abused to mean different things to different people. At Factorsixty we work strictly according to ISO 9241, the world standard on Usability. Our usability reports are also standardized in the “Common Industry Format”, ISO 25062.

Usability engineering in a complex world

Every product, no matter how simple in its idea, lives in an increasingly complex, interconnected world. This gives rise to unexpected behaviors, failure modes, but also opportunities. Only a complex-systems approach can help you steer away from pitfalls and exploit new opportunities.

Half of the visitors abandon a website and don’t come back if it is difficult to find what they need. E-commerce sales lost due to bad usability are frightening: 3.8 billion USD already in 2015.

A mistake that costs 1 EUR during design, will cost 6 EUR in development and at least 60 EUR in maintenance. This is the “sixty” factor. This is what usability saves.

A major e-commerce site lost 300 million USD of sales every year because their checkout process had bad usability.

One Usability Audit is enough to start you saving costs, doing more sales, and delighting your customers. Call us.

Complying with the law

Germany’s law of employee protection mandates that all software used by employees must fulfill strict usability criteria, similar to the ones in ISO 9241. Avoid legal problems by improving the usability of your software.

Increasing sales

Designing your products according to usability criteria makes them friendlier, easier to use, easier to learn, and easier to love by your customers. Products look better, demo better, and sell better.

Lowering costs

Usability gives you better requirements, better work efficiency, and fewer customer problems. It saves you from expensive mistakes and saves development and maintenance costs, personnel costs, and technical support costs.

Increasing productivity

You are as productive as your tools allow you to be. By optimizing the usability of the software you have, and by paying attention to usability of the software you want to buy, you increase productivity and shorten training time.

Identifying opportunities

Usability deals with recognizing and solving problems with a product. This means we can also recognize problems and market opportunities that your competitors have not yet addressed and help you take advantage of them.

Diversifying products

Usability opens the door to a global market which expects usability as a standard feature. Usability analyses reveal opportunities and pain points in new fields and markets, enabling a successful entry with little expense.
