Led UX/HMI concept development for instrument cluster and ADAS across the Porsche 911, Panamera, and Cayenne, delivering validated specification-ready designs.
The Challenge
Porsche's instrument clusters and driver-assistance systems sit at the intersection of performance engineering and driver experience. Getting them wrong — even slightly — has consequences that extend from regulatory compliance to brand perception. Between 2015 and 2017, Porsche required HMI concepts for the instrument cluster and ADAS across three distinct model lines: the 911, Panamera, and Cayenne.
Each series carries its own driver profile, interior architecture, and interaction logic. A concept validated for the Cayenne's SUV context does not automatically translate to the 911's sports-car cockpit. The work therefore required not just design output but coordinated, specification-ready documentation that engineering teams, suppliers, and management could build from and align on — simultaneously, across all three platforms.
The challenge was structural as much as it was creative: how do you develop coherent, validated HMI concepts at that scale without letting complexity degrade the quality of individual decisions?
Key Decisions
- 01
Working at Specification Level, Not Concept Level Alone
Early in the project it became clear that producing polished wireframes without simultaneously maintaining requirement specifications would create downstream friction with engineering and suppliers. The decision was made to treat documentation — flowcharts, state diagrams, annotated wireframes — as a primary deliverable, not a follow-on task. This slowed the pace of visual iteration but ensured that every concept handed off to a supplier or reviewed in an engineering session was immediately actionable, with no translation gap between design intent and technical requirement.
- 02
Treating Each Model Line as a Distinct Interaction Context
Rather than establishing a single master HMI framework and adapting it across the three series, the approach maintained model-line specificity throughout concept development. The 911, Panamera, and Cayenne have meaningfully different drivers, seating positions, use cases, and brand promises. Forcing a single template would have produced something technically consistent but contextually wrong. The trade-off was increased complexity in maintaining three parallel workstreams; the benefit was concepts that were appropriate to each car rather than merely applied to it.
- 03
Embedding Validation with Management and Engineering Early
Validation was not positioned as a gate at the end of a design phase but as an ongoing activity woven into the development cycle. Concepts were regularly reviewed with both management and engineering departments throughout the process. This created friction in the short term — designs were challenged earlier and more frequently — but it eliminated the risk of late-stage rejection and ensured that the specifications delivered at project close were genuinely agreed-upon, not just submitted.
- 04
Coordinating Supplier Input as Part of the UX Process
Supplier relationships were treated as part of the HMI development process rather than a handoff that happened after design was complete. Supporting suppliers throughout the concept phase meant that technical constraints surfaced early and could be addressed within the design, rather than forcing compromises after specifications had already been set. This required maintaining clear, consistently updated documentation and acting as a reliable point of contact between the design rationale and the supplier's implementation reality.
The Solution
Over two years, the UX concept work spanned the full instrument cluster and ADAS interaction surface across all three Porsche model lines. Deliverables included validated wireframes, flowcharts, and state diagrams maintained as living requirement specifications. The work covered not just initial concept creation but the ongoing maintenance and refinement of those specifications as engineering input, management review, and supplier feedback shaped the details.
The result was a set of specification-ready HMI concepts for the digital driver's workplaces of the Porsche Panamera, Cayenne, and 911 — documented to a standard that allowed engineering teams and suppliers to work from them directly.
The Results
Validated HMI concept specifications for the instrument cluster and ADAS systems were delivered across all three model lines, covering the complete digital driver's workplace for the Panamera, Cayenne, and 911. The specifications were coordinated with and accepted by both management and engineering departments, and supported supplier implementation throughout the development cycle.
The work demonstrated that HMI concept development at multi-platform scale is achievable without sacrificing model-line specificity — provided documentation discipline and cross-functional validation are treated as core design activities rather than administrative overhead.
"A great support in automotive research & interaction concepts. His conceptual work has advanced our project and helped shape the user interface. The results, flexibility and communication were to our complete satisfaction."
