Navigating Product Trade-Offs
The Conflict: Stakeholders wanted an interface with "Apple-like simplicity," yet simultaneously requested that all menu items be visible on a single screen to "save taps." Furthermore, they wanted all possible payment methods crammed onto the checkout screen for QSR environments.
The Pushback: I advocated that visual clutter is the enemy of speed. Putting 50 items on one screen doesn't save time if the user has to spend 5 seconds hunting for the right button.
The Resolution: I successfully nudged stakeholders toward a smart categorization model. For our extreme high-volume "LITE" POS deployed for food stalls at the massive 2023 Singapore F1 Grand Prix, I took this a step further. I designed an aggressive information hierarchy that anchored fast-moving, high-frequency items at the top of the screen, dynamically pushing lower-priority items down. For the payment screen, I engineered a consolidated checkout view that accommodated all payment types without sacrificing touch-target size or speed.
The Solution & Execution
Robust Search & Filter Architecture
Replaced chaotic lists with a clean, fast-tap modular grid featuring oversized touch targets. This ensured staff could confidently input orders using muscle memory, minimizing mis-taps during high-stress rushes.
Engineered a frictionless flow for complex scenarios. Menu modifiers (e.g., "no onions, extra sauce") were elegantly nested to avoid cluttering the main screen, and the notorious "split bill" process was simplified into a visual, drag-and-drop-style interaction.
Implemented a strict, universally understood color-coding system to indicate order status (e.g., prep, ready, paid) and proper information hierarchy, allowing floor managers to assess the state of the restaurant with a single glance.
