A sales estimate alone does not prove that a product should be launched. A useful viability review asks whether the opportunity can survive realistic costs and execution risks.
Demand and competition must be read together
High demand can attract strong competition. A product becomes more interesting when demand evidence is supported by a credible reason customers would choose a new offer.
Margin protects the plan
Thin margin gives the launch little room for advertising, fee changes, returns, or supplier mistakes. Product research and profit calculation should therefore be completed together.
Capital fit matters
A good product for a large operator can be a poor first product for a capital-constrained beginner. MOQ, lead time, safety stock, and reorder funding belong in the viability decision.
Use a score as a checklist, not a promise
The score should expose weak evidence and force a better question. It cannot guarantee demand or success. A caution result means the product needs stronger validation before inventory is committed.
