Not all evidence is created equal. There are times for quick decisions and rapid prototyping ("thinking fast"), and times where meticulous, high-quality evidence is crucial ("thinking slow"). This differentiation in our approach to evidence collection and application is particularly critical in automotive UX, where safety and usability are not merely features, but foundational pillars.
In the world of automotive UX, the arrival of talented professionals from fast-paced industries is immensely valuable. However, it is vital to recognise that automotive UX is not merely about crafting another interface; it is about enhancing the interaction between humans and machines in contexts where safety cannot be compromised. While there is a tendency to rely on testimonials and storytelling, it is crucial that we ensure these stories are backed up with evidence.
Automotive UX is a cyclical process, particularly in its early phases, rather than linear. However, several important milestones must be acknowledged:
Concept Creation: Creativity dominates this initial phase. I take a step back here, allowing designers the freedom to innovate and push the boundaries to forge compelling concepts.
Concept Selection: This phase is a transition from creativity to critical evaluation. It demands solid evidence to reduce uncertainties. We employ straightforward yet effective methods like tablet prototypes, desktop simulations, and VR. These tools help refine our options quickly and select the most promising concept for further development. If the evidence points to no clear winner, then, as I often say, "this is a design call."
Concept Refinement: The pace intentionally slows as we advance. Attention shifts to detailed, rigorous testing and meticulous evidence collection. Advanced simulation tools, mules, early prototypes, and VR are crucial for gaining a deep understanding of user interactions with both physical and digital interfaces. This stage emphasises precision, aiming to ensure the interface is safe, inclusive, and enjoyable. Selecting a representative sample of users is vital for achieving truly inclusive design.
Final Validation: The peak of our efforts involves advanced simulation and on-road testing. If previous stages are executed effectively, this typically becomes a formality—requiring only minor tweaks rather than major overhauls. At this stage, any changes, especially to hardware, become costly and can significantly disrupt production timelines, emphasising the importance of the meticulous processes employed earlier.
In summary, automotive UX demands a balanced approach to evidence—both fast and slow thinking are essential, but each must be applied carefully to serve our ultimate goals of safety, usability, and customer satisfaction.
