Definition
A comprehensive description of the target customer, problem to solve, core functions, implementation principles, and key differentiators; it is a product hypothesis to be validated before detailed design.
In detail
A product concept describes 'what is planned to be done and roughly how it will be achieved,' while a value proposition describes 'why customers should choose and be willing to pay'; the two are related but not the same. A product concept can include structure, technical route, and usage method, yet still lack a compelling customer value; conversely, a clear value proposition may have multiple product concepts. Development teams should separately validate customer attractiveness and technical/manufacturing feasibility.
Example in practice
The team found that lab personnel need to reduce manual pipetting errors. The value proposition is 'improve repeatability and reduce preparation time without increasing training burden.' The team proposed two product concepts: an automated pipetting workstation and a smart pipette with visual verification. They built prototypes for each and validated usability, cost, and manufacturing risk before selecting a solution.
