Formal and informal communication are just as necessary in the company. The first refers to communication that takes place through official channels in the organisation. This type of communication takes place between managers or employees at the same level or between superiors and subordinates, and vice versa. It can be oral or written, but the complete record of such communication is kept within the organisation.
Informal communication is often used for communication at a personal level, but it also occurs in the work environment and within the workplace. It is usually done face-to-face or through a phone call or message. Compared to formal communication, it has no official recognition and is not supported by any specific communication principles in the organisation. However, it is said to be the best way to maintain the positive atmosphere and climate that makes everyone enjoy their time together in the company.
Formal communication is a system of communication based on officially designated channels and systems. In an organisational setting, formal communication is described as the sending and receiving of official documents, letters, memos, reports, policy or procedure manuals, among others.
This form of communication is supported by authoritative organisational structures and guidelines, which help to ensure that it is understood by everyone in the organisation. An example is confidential information, which is only intended for the recipient, and must be communicated in a formal communication environment.
The main advantages of formal communication include two:
But, This way of communicating has its drawbacks, one of the main ones being that, should problems arise that need immediate solution, it requires too much bureaucracy, This translates into management time and delays in taking action.

Nevertheless, Formal communication can be improved, for example, by following these recommendations:
These recommendations are simple and easy to put into practice, but they are following them helps to maintain the right tone in corporate communications, avoid legal liability, and increase productivity.
It is about objectives that are not only limited to one form of expression and should be considered in terms of both formal and informal communication.
This type of communication is based on personal relationships with someone and, for the same reason, is free from all organisational formalities and corporate rules. Compared to formal communication, informal communication does not have a certain classification, therefore, for the same reason, it can take very different forms.
One of the main disadvantages of informal communication is that it is not supported by written documents and therefore, it is not usually possible to use as evidence or means of proof in case of need.
On the other hand, the main advantage of informal communication is its speed and agility, which boosts decision-making.
Formal and informal communication can be optimised and, if in previous lines we saw how to obtain results more in line with expectations in formal communication, this optimisation can be taken to the personal realm if:
The main difference between formal and informal communication is that formal communication is always supported by predefined communication channels, while there are no established rules for informal communication.
In addition to this distinction, there are other distinctions, such as the times at which the two types of communication occur or the messages can be exchanged quickly and efficiently, and their feedback.
Both types of communication are essential for companies and their teams, and therefore care must be taken to ensure that optimal conditions are maintained so that in both cases the exchange of information is as effective as possible.
