What this question tests

Product sense for a specific underserved user, translating physical and cognitive needs into concrete store design choices.

Identify pain points for older shoppers, small label text, long walking distances, heavy items, and difficulty finding staff.
Prioritize the top one or two pain points, readability and physical fatigue, rather than trying to fix everything.
Propose concrete solutions, larger print shelf labels, motorized carts and seating areas, and a dedicated help button or staff zone.
Consider the layout, wider aisles and reduced walking distance to core staples.
Define success metrics, basket size and visit frequency among older shoppers, plus satisfaction scores for this segment.

Grounds the design in specific physical and cognitive needs rather than generic make it nicer changes.
Prioritizes ruthlessly, picking readability and reduced walking distance as the top two fixes instead of listing every accommodation.
Sets a segment specific metric, visit frequency and satisfaction score among shoppers 65 plus, to prove the redesign actually helped.

Listing every possible accessibility feature with no prioritization.
Treating older shoppers as a monolith with no consideration of varying mobility or vision needs.
No metric to measure whether the changes actually improved the experience.

How would you test these changes before rolling out to all stores?
How would you balance this against the needs of younger shoppers in the same store?
