Production process as value proposition. In this study, we found that the production process plays an important role as a value proposition: a promise from producers to customers that products or services could help them create value for themselves (Vargo and Lusch 2004). The evidence from our empirical study found that the production process of amulets, including incantation, material, quality, and quantity, could play a role as brand identity and a source of brand co-creation. Members can extend the discussion and co-create myth through this process.
