Stage 2: Define User Experience

By analysing the context of use, we lay the foundations for a specialised and optimally user-centred operating concept. In doing so, we specifically examine the functionality and operation of existing systems in real-world working environments. We observe users directly at their workstations and conduct interviewsi with users of varying levels of expertise to understand their actual needs. The current software quality is assessed using ISO questionnairesi. In addition, we organise workshops with the manufacturer’s specialist departments to identify all stakeholders’ requirements regarding the system’s operation. This creates a robust basis for well-founded conceptual and design decisions.

Prototyping

In this phase, we define the usage requirementsi and develop the information architecturei. Tasks are identified, assigned to user rolesi or personasi, and organised into structured workflowsi and scenariosi. Using paper prototypingi, initial ideas are developed and implemented as clickable prototypesi through wireframingi; these are then packaged into user storiesi and improved iteratively.

The result is an interface that is intuitive, logically structured and easy to learn. Users can confidently monitor processes, adjust parameters, quickly log messages and efficiently resolve faults – supported by clearly structured statistical and diagnostic data. This creates a positive user experiencei for everyone – with genuine joy of usei.

Testing

In structured usability testsi, we evaluate the user interface design with selected users – in other words, precisely those people who work with the machines on a daily basis. During these tests, they carry out predefined task sequences in an interview settingi, whilst we observe their behaviour and gain insights into their perceptions through the ‘thinking aloud’i method. In addition, we again use standardised ISO questionnairesi to measure improvements in usability and identify further potential for optimisation, which can then be incorporated into the next iteration. In this way, we gradually create the best possible user experience.
