consulting is a professional service specialized in areas, provided by companies or professionals (known as consultants or consultants, respectively) with specific experience or knowledge in an area, advising people, other companies, groups of companies, countries or organizations in general.

You can focus on comprehensive consulting or on a specific area, such as Administration, Human Resources, Operations, Marketing, Sales and Finance.

Consulting goes back to the origins of human relationships. It is the time to verify through deliberation any matter that requires prudence. It constitutes reflection in search of an answer through the most appropriate advice.

Anthropological records define as a common feature to the emergence of human societies the emergence of individuals accepted as guides, who advised their communities on all issues, from internal community relations to actions to organize hunts or war, including aspects of physical and psychological health.

According to Professor Paulo Ricardo Becker Jacinte,[1]​ in ancient Greece, the priests of the Oracle of Delphi gave their advice based on their systematic and intelligent observations of natural phenomena, which were understood at that time as predictions from beings chosen by the gods and endowed with special powers.

It was in this environment that the first philosophers and the ideal of the search for knowledge and rational understanding of the world and humanity through science emerged.

It was not until the beginning of the century that the consultant came to gain the now well-defined and characterized patterns of activity. Especially in the 40s and 50s in the United States and Western Europe there were important advances in the systematization of consulting work with very technical and scientific ties, together with experience and based on theories, but always with a focus on practical solutions.

It can be concluded that consulting is the transmission of knowledge and experience from an expert person or team to others with the aim of more easily achieving a goal. Essentially, it is the constant search for knowledge prepared for the benefit of others. In the words of Peter Block "Consulting at its best is an act of love: the desire to be truly useful to others. Using what you know, or feel, or suffer along the way to lessen the burden of others."[2]​.
