For a new product or service, Apple should consider a coherent marketing mix that includes the 4Ps - Product, Price, Place, and Promotion. This process involves understanding customers' wants and needs, the physical appearance of the product, its quality and reliability, as well as pricing strategies based on cost and customer preferences. Additionally, the product must be made available in the right place at the right time, and a promotion strategy using the AIDA model (Attention, Interest, Desire, and Action) can help raise awareness and drive sales.
