The interdisciplinary character that has the marketing does to him to be not exact science, therefore he encourages the creation of different theories, opposing opinions and selection of strategies that can go so far as to differ enormously in his expositions, but not so much in the results.

Let's think the infinity of criteria that can be adopted inside the Sociology, Psychology, Economy, Statistics, Right, History... to realize the big number of ways that we can choose facing the attainment of the targets that we mark ourselves.
This complexity added to those who arise in the proper activity does that the good professionals of the marketing have a strong labor demand, since the piled up experiences will facilitate the decision making to them.

As for the areas of activity that compose his management they can be summed up in six:

• Markets investigation.
• Programming and product development, price making.
• Channels of distribution and logistics.
• Integral communication: publicity, communication and image, public relations (RR PP), direct marketing, promotion, etc.
• Organization of the commercial department.
• Internet and new technologies.

Each of these variables can be handled according to the criterion of the specialist in marketing, as it is not necessary to use all the skills here exposed, since the needs of the clients are different in form and time, except Internet, which in major or minor measurement is something essentially his use in the companies of success.

Also, my experience indicates me that across the reading of the book I am going to be providing the reader of a series of hardware of work that depending on how I used them or I stopped using them, the results will be outcropping in major or minor measurement.
