An entrepreneur correctly identified the customer problem but the solution was difficult to use. What may be the main reason for failure?

Correct answer: Lack of user convenience in the solution

Recognising a real problem is only the first step. Customers must also be able and willing to use the solution easily in their daily context. A confusing process, excessive effort, or poor accessibility can prevent adoption even when the underlying need is genuine. User testing can reveal and correct these obstacles.
