Periodization in Macromarketing,

Modifications and extensions[edit]

To overcome the deficiencies of the 4 P model, some authors have suggested extensions or modifications to the original model. Extensions of the four P’s include “people”, “process”, and “physical evidence” and are often applied in the case of services marketing[50] Other extensions have been found necessary in retail marketing, industrial marketing and internet marketing:

  • Industrial marketing or B2B marketing needs to account for the long term contractual agreements that are typical in supply chain transactions. Relationship marketingattempts to do this by looking at marketing from a long term relationship perspective rather than individual transactions.[51]
  • Services marketing needs to account for the unique characteristics of services (i.e. intangibility, perishability, heterogeneity and the inseparability of production and consumption). In order to recognize the special challenges involved in selling services, as opposed to goods, some authors advocate extending the model to 7 Ps for service industries by adding; Process – the way in which orders are handled, customers are satisfied and the service is delivered; Physical Evidence – is tangible evidence with which customers interact and with the potential to impact on the customer’s service experience; People – service personnel and other customers with whom customers interact and form part of the overall service experience.[52]

Expanded marketing mix for retail

  • Retail marketing needs to account for the unique facets of retail stores. A number of authors have argued for the inclusion of two new Ps, namely, Personnel and Presentation since these contribute to the customer’s unique retail experience and are the principal basis for retail differentiation. Some scholars also recommend adding Retail Format (i.e. retail formula) since it contributes to customer expectations.[53] The modified retail marketing mix is often called the 6 Ps of retailing.[54][55]
  • Internet marketing presents both marketing practitioners and scholars with special challenges including: customer empowerment, new communication modes, real-time interactivity, access to global markets, high levels of market transparency and difficulty maintaining competitive advantages. While some scholars argue for an expanded marketing mix for internet marketing, most argue that entirely new models are required.[56]
  • Some authors cite a further P – Packaging – this is thought by many to be part of Product, but in certain markets (Japan, China for example) and with certain products (perfume, cosmetics) the packaging of a product has a greater importance – maybe even than the product itself.
