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 communication system that relies 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 authorised organisational structures and guidelines, which help ensure that everyone in the organisation understands it. One example is confidential information, which is only intended for the recipient and should be communicated in a formal communication setting.
Among the main advantages of formal communication, two stand out:
But, This form of communication has its drawbacks, and one of the main ones is that, should problems arise that require immediate resolution, it involves too much bureaucracy., which 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 following them helps to maintain the right tone in corporate communications, avoid legal liability, and increase productivity.
It is about objectives that are not solely limited to one form of expression and which should be considered with regard to formal and informal communication.
This type of communication is based on personal relationships with someone and, for the same reason, is free from all kinds of organisational formalities and corporate rules. Compared to formal communication, informal communication has no set structure, and therefore, for the same reason, can take very different forms.
One of the main disadvantages of informal communication is that it lacks the support of 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 drives decision-making.
Formal and informal communication can be optimised and, if in the preceding lines we saw how to obtain results more in line with expectations in formal communication, this optimisation can be taken to the personal sphere if:
The main difference between formal and informal communication is that formal communication is always supported by predefined communication channels, whereas there are no established rules for informal communication.
In addition to this distinction, there are others such as the times when one and the other communication occur or the messages can be exchanged quickly and efficiently, and their feedback.
Both types of communication are essential for businesses and their teams, and for this reason, optimal conditions must be maintained so that, in both cases, the exchange of information is as effective as possible.
