Metter Toledo is the world market leader for precision scales. Their products not only offer extensive features, but also excellent software that is characterized by high usability. We at interfacewerk had the privilege to support Mettler-Toledo with the HMI (Human-Machine-Interface) design and to contribute our many years of experience in UX design. Because Mettler Toledo recognized early on that good software is now a clear quality feature that is increasingly coming to the fore. The latest technology deserves a design that not only looks good, but also convinces users to work with the device.
For our HMI designers, the first step was to identify use cases. The second step was to design the simplest and most intuitive workflows to map the use cases. Another important point was to establish a consistent design system. This forms the basis of all further iterations and is used at Mettler Toledo to develop new features quickly and in line with the design of the application.
The special feature and at the same time the biggest challenge were the extremely extensive set of functions of the application. One has to imagine that the scales are used all over the world in very different stores with their own special requirements. The product is highly flexible and configurable due to the modern and open system, as it has to map many use cases. These use cases had to be identified and the best, simplest and most intuitive workflows had to be found.
Since we set up an individual UX process tailored to each customer, the first challenge was to understand the users of the scale at the fresh food counter and to capture their pain points and needs.
Use cases identified, workflows recorded, user needs captured.
Close collaboration between our designers, the client's developer side and product management formed the basis of the project. Our designers defined personas to meet their requirements for the software. In an iterative process, with many feedback loops, the workflows were mapped. This made the design not only appealing and beautiful to look at, but UX-led.
In the prototyping process, our designers developed features that activate the users' muscle memory so that they can work faster and more intuitively. Through intuitive workflows, users build trust in the software and feel safe and optimally supported by the software. Our UX designers have discovered areas in the software that have previously caused uncertainty among users.
By optimizing workflows, we have made them more intuitive. Users are now also empowered to solve problems on their own and get support through interactive elements. The design also reflects the brand essence of the product: it is bold, fresh, feature-rich and easily customizable.
We created a look that was bold, cool, authentic and supported a positive user experience.
After all, a positive and friendly first impression of the product is the basis for the trust that the user should develop in the product. The scales should not only enable users to do a job, but also provide a certain feel-good factor.

Tested prototype solutions, incorporated multiple feedback loops, optimized workflows, customized design.
We placed special emphasis on maximizing interaction speed to create a seamless user experience in hectic fresh counter work situations. In addition, we established a consistent design system that ensured uniformity and user-friendliness, regardless of application or device type.
Apart from an intuitive user interface, our designers gave the interface the right look and feel in line with the CI and the UI.

"The fusion of user-centered design and agile development is the key to good products. Currently, we are also continuing to work together on new features for the scale that will help users even more to manage their daily work quickly and easily."
