Marketing management is not only marketing as a concept, but more globally, the management of all stakeholders and more specifically "the human being" whether it is a customer or a salesperson. This book proposes some answers, along with an exploration of the foundations of marketing. To do so, we will first examine the origins, the etymological understanding and how marketing allows the creation of value for the consumer and for the company. We will then analyze the roles and contributions of marketing in the sales process in companies, while evoking the major obstacles and changes that influence marketing today. Finally, we will discuss the place of the "human being" as a key factor in the sale and positioning of the company through product, price, distribution, and integrated marketing communication policies with the customers of choice for a constant sale and, at the same time, a victory over the competition. No need to recommend it again, this book is made for you.
