The value proposition is the offer made to a potential customer.
It's tempting to think of "the offer" as the firm's product or service. Resist the urge to think in these terms. It's product-based thinking. It frames matters in your terms, not your customer's.
A model-based definition says the value proposition is a promise-based solution offered to a potential customer's problem.

The marketing viewpoint as expressed in Theodore Levitt's classic Marketing Myopia
The innovation viewpoint as presented by Clayton Christensen's classic The Innovator's Dilemma
