Concluding remarks
As the promise theory demonstrates, for marketing to be successful, promises that have been made must be properly fulfilled. In relationship marketing, as an ongoing process, there is no singular product, as in a conventional marketing model, that guarantees successful promise keeping. Instead, the interaction process in the relationship marketing model, depicted in Figure 1, is responsible for how promises are fulfilled as well as how relationships are maintained and enhanced. Therefore, in the present commentary, I have concentrated on this critical aspect of a marketing process. Unless a firm is prepared to keep promises successfully – in conventional marketing through a product and in relationship marketing through an ongoing interaction process – it is not fully prepared to implement marketing. Because of its critical importance to the successful marketing process of how promises are fulfilled, the RMR assessment model presented here covers the firm’s readiness to keep promises. In parallel, assessments of how well promises – made through, for example, sales, marketing communication and price offers – are fulfilled are of course also important. For relationship marketing to be successful, marketing has to be reinvented. The management of the whole interaction process must be included in the marketing process. A singular product concept is not enough to encompass the many different facets of the promise-keeping process. To paraphrase Lynn Shostack’s (1977) demand from 40 years ago, marketing must break free from product marketing. Doing this will lead to an almost revolutionary change in how marketing is conceptualized, organized, resourced, planned and managed (Grönroos, 2015). This is, however, beyond the scope of this commentary.
