Launch

2021

JØNI is among the leading equipment manufacturers of energy-efficient tilting kettles for commercial kitchens. We helped design the user interface, ensuring an easy-to-use, intuitive user experience.

The challenge

Our biggest challenge was creating a natural transition from analog controls to a digital display. The internet-enabled kettle also connects to a cloud platform where data, service, and recipes are maintained. The experience had to be cohesive across kettle and web.

“The process has been both iterative and creative. The approach has led to excellent results for both us and our clients.”

Our approach

The initial phase was an agile, high-intensity collaborative effort between us and JØNI. We defined project milestones, audited the existing work, researched the competitor landscape, and defined a clear vision.

We also coordinated with the external development team to better understand technical feasibility and constraints.

Finding product-market fit

The user interface had already been through a few iterations. A lot of thought had gone into the product experience; we started filtering through documentation and prototypes to decide on a Minimum Viable Product.

Rethinking the experience

We worked closely with JØNI’s Mechanical Engineer, Uffe Pilgaard, to update the information architecture, prototypes, long and short-term goals, and undiscovered features.

Designing for delight and daily use

Apple’s Human Interface Guidelines—especially their research for the CarPlay-technology—helped shape our visual design language.

  1. On-screen information is minimal, relevant, and requires little decision-making.
  2. Primary content always stands out and feels actionable.
  3. Actions are thoughtfully placed to ensure better ergonomics.
  4. Color scheme is legible under a variety of lighting conditions.

The final design is an experience optimized for the cooking environment to meet the unique demands of kettle operators.
