How we discovered that perceived ease and actual understanding are not the same thing.
Lifeway was introducing a Savings Progress Bar to the checkout experience — a UI showing customers their current discount tier and free shipping eligibility as they built their cart.
Three design variations were created. Each communicated the same pricing system but used different visual hierarchies, labels, and progress indicators.
The question: would customers actually understand what the bar was telling them?
If users misread the pricing system, they'd face unexpected totals at checkout — eroding trust at the highest-friction point in the purchase journey. The stakes were real.
Do users understand what the two tracking bars represent — savings thresholds versus free shipping eligibility?
Can users correctly identify what discounts are active and what they need to spend to unlock the next tier?
Across three design concepts, which communicates the pricing system most accurately?
Participants reviewed one design and answered a structured set of questions without a moderator present.
Multiple choice comprehension tasks, 5-point rating scales, and open-ended questions — analyzed together for a complete picture.
Each participant saw one design only, eliminating order bias. Results compared across groups post-study.
Comprehension Accuracy (%) — All Three Designs
The catch: Design 3 scored highest on user ratings — 4.50 on ease of use and savings clarity. Design 2 rated lower on both. Users felt Design 3 was clearest. The comprehension data told a different story.
Perceived ease
≠ actual understanding.
Design 3 felt easiest. Design 2 was understood best — 92% core accuracy, 85% overall comprehension, outperforming on every comprehension measure. A design that feels simpler can still ship users into confusion, especially when the stakes involve pricing.
Highest core accuracy (92%) and overall comprehension (85%). Grounded in evidence across all three comprehension metrics — not perception.
Design 3 excelled at perceived savings clarity. Selective copy and visual elements from Design 3 can be layered into Design 2 without compromising comprehension.
If stakeholders remain divided after refinements, a live A/B between Design 2 and the refined version provides real behavioral data at scale.
