According to my dictionary a proposition is "a suggested scheme or plan of action, especially in a business context", or "a statement or assertion that expresses a judgement or opinion."
The same dictionary says a value proposition is "(in marketing) an innovation, service, or feature intended to make a company or product attractive to customers."
Further my dictionary says a promise is "a declaration or assurance that one will do something or that a particular thing will happen."
When I google value promise I get stuff about value propositions!
For me a value promise is far more powerful than a value proposition.
