# CS-16: Product comparison for a considered purchase

Category: Commerce & marketplaces
Level: Beginner
Suggested duration: 2–3 weeks

Original UXCharan practice scenario. Validate assumptions; do not present it as a commissioned client project.

## Problem
A fictional store presents long specification lists without explaining differences. Investigate how buyers compare options for their own constraints, while keeping trade-offs, full costs and unavailable information visible.

## People to learn from
Shoppers comparing household appliances

## Core scope
- Choose criteria
- compare products
- review a shortlist

## Research questions
- Which criteria actually drive a choice?
- Which specifications need explanation?

## Edge cases
- Unknown specification
- unavailable item

## Specific artefact
A comparison matrix and prioritised content hierarchy

## Evaluation question
Can participants explain their choice using relevant product differences?

## Work to share
Problem and role; anonymised evidence; alternatives and rationale; task flow; prototype; accessibility considerations; testing findings; revisions and honest limitations.
