What this question tests

Product design for a social commerce tool, checking whether you can identify the real friction sellers face on Instagram beyond simply 'add a store'.

Define the user: a small business or individual seller using Instagram posts and DMs to sell, without a dedicated e-commerce site.
Identify current pain points: sellers manually track orders through DM screenshots and comments, with no organized inventory or payment system.
Prioritize order and payment organization over discovery features, since sellers' biggest daily pain is operational chaos, not lack of buyers.
Propose a design: a lightweight storefront layer that turns tagged posts into orderable listings, with built-in checkout and automatic order tracking replacing manual DM management.
Address low-effort onboarding: let sellers convert existing posts into products with one tap rather than requiring a full catalog setup upfront.
Define success as reduced time sellers spend on manual order tracking and increased completed transaction rate per seller.

Identifies operational chaos, not discovery, as the core problem for small sellers, a sharper insight than a generic 'more visibility' answer.
Proposes converting existing content into products with minimal setup, respecting that small sellers won't do heavy manual catalog work.
Ties success to time saved and transaction completion, both directly tied to the operational pain point identified.

Assuming the main problem is buyer discovery rather than the seller's own order and payment management chaos.
Proposing a heavyweight storefront setup that small, informal sellers would abandon before completing.

How would you handle payment processing and fraud risk for informal sellers?
How would this differ for a one-person seller versus a small business with a team?
