What is consultancy?
Consultancy is an activity that consists of diagnosing problems and solving them. This way, consulting services can be offered either by a professional expert in the area in which the consultancy needs to be performed or by a consulting firm.

We have separated some topics to help you better understand what consultancy is.
Diagnose problems
A consultant specializes in diagnosing problems. The problem will not always be what the client thinks, because often what he believes to be the problem is Many types of consultancy cover just a symptom.
It is up to the consultant to know how to accurately identify errors so that all subsequent analysis is carried out on the root cause. Pay attention to this, because if this study is not done with caution, you can rack your brain over issues that will not generate results!
Propose solutions
This is a key moment in consulting! On top of the diagnosed problems, the consultant must propose solutions, stipulate schedules and decide what will be treated as a priority.
The consultant must also have the skill to prioritize the problems that cause the most impact on the company’s final result, but without letting other causes remain without proposed solutions.
Implement the project
At this stage, the idea is simple. On top of the proposed solutions, if the customer agrees, the project will be implemented. It is the final phase of the consultancy, where everything previously analyzed and proposed will be carried out.
Consultancy: where did this term come from?
The word consultancy, as you can see, came from Latin. It can also be understood as “Consultare”, that is “to receive advice from someone”.

This term originated from Ancient Greece, with the priests of the Oracles of Delphi. At that time, these priests were the society’s consultants, as they were always sought after in search of knowledge and to solve misunderstood issues.
But what about today? Our next topic will deal with how consultancy has been adapted to our reality over time. Follow us!
How did modern consultancy come about?
We've already given a little hint of the role of a consultant, so it’s easier for you to imagine when that term gained momentum again, right? Since the consultant is a problem solver, there is no better scenario for him than a crisis.
And it was precisely in the 1929 crisis that this term resurfaced. With the need for reorganization, the market had to look for professionals who were experts in solving problems and leveraging results!
Soon after, there was the post-war expansion in the 40s and 50s in the USA and Western Europe and, consequently, it was necessary to focus on practical solutions based on technical and scientific foundations.
In this way, all these events made the concept popular around the world in the 1990s.
