To complete the alphabet soup of Marketing-Mix models we have the 4Cs, with the Cs representing Clients, Costs, Communications, and Convenience:
Clients – find what the customer wants and needs. Then create the Solution.
Costs – consider all costs in satisfying the customer, including costs that customers themselves will incur to find, purchase, use, and potentially dispose of your Solution.
Communication – what are all the communications and touchpoints between the business and the customer. For instance, how is a prospective customer going to learn of your Solution’s existence?
Convenience – how and where does the customer want to purchase?
