An HMI redesign makes sense if you recognise one or more of the following challenges:

• The machine is technologically advanced, but the user interface looks outdated.
• The system currently requires too much training and experience to operate safely.
• The existing control system should continue to be used and a complete reimplementation is currently not planned.
• Your customers are increasingly evaluating the machine’s user interface as well.
• Sales and marketing teams find it difficult to present the software as a product advantage.
• Different machines or modules should have a more consistent operating concept.
• Internal teams need a solution that remains maintainable and transparent.

We specialise in Siemens SIMATIC WinCC v7/v8, but can generally also work with other SCADA, HMI or PCS systems, provided they offer suitable options for UI customisation – for example through a design editor, graphics editor or CSS editor. These include systems such as Siemens SIMATIC WinCC OA (Open Architecture), Ignition, AVEVA System Platform, Rockwell FactoryTalk and GE Vernova Proficy CIMPLICITY or iFIX. During a free initial consultation, we analyse your tech stack and discuss which adaptations can realistically be implemented. For further project steps, a suitable software licence or test environment may need to be provided.

The exact deliverables depend on the HMI or SCADA system being used. Depending on the software, the redesign can be delivered as a UI concept, design system, screen design, component library, style guide or as a directly implemented adaptation within the existing framework. During a free initial consultation, we analyse your tech stack and jointly define the appropriate project process – from the design phase through to potential integration into your system.

We do not design HMI interfaces in isolation from technical reality. Instead, we consider the existing software environment, its possibilities and its limitations from the very beginning.

Elaborately designed interfaces can often only be implemented to a limited extent in existing HMI systems or require considerable implementation effort. With our experience in industrial applications, HMI frameworks and industry-specific requirements, we develop designs that not only look good but can also be realistically implemented within the respective system.

Our focus is on the interface, usability and operator experience. We look at the HMI from the perspective of the people who work with the system every day: Which information is important? Which states need to be recognised quickly? Which workflows can be made clearer, safer and more efficient? We focus on UX/UI design, visual structure, operating logic and interaction quality – without putting the process itself or the system’s fundamental functionality at the centre of our work.

Whether an HMI redesign can be implemented during ongoing operation depends on the respective system, the system architecture and your internal approval processes. Our approach is designed to work as closely as possible within the existing HMI environment and to make targeted adaptations at UI level. Depending on the project, the redesign can be planned as a step-by-step optimisation of individual screens, a more comprehensive interface modernisation or as part of a larger process or system change.

We consider relevant standards, guidelines and industry-specific requirements within the design process and can incorporate them into the analysis, concept development and design of your HMI. The relevant standards depend heavily on your industry, application and target environment. In your enquiry, please describe the industrial sector in which the HMI is used and which standards or internal requirements are important for your project. Based on this information, we can assess the requirements more specifically during the initial consultation.
