Communication can be categorized into two main types: formal and informal. Understanding the differences between these two forms of communication is essential to ensure that the intended message is conveyed accurately and appropriately. In this section, we will explore:

10 Differences between formal and informal communication 

1) Setting: Formal communication is used in professional or official settings, such as business meetings, academic conferences, or legal proceedings. Informal communication is typically employed in non-professional or relaxed environments, such as social gatherings with friends or interactions with family members.

 2) Rules and Procedures: Formal communication follows established rules and procedures, such as those related to addressing individuals by their formal titles such as Mr. or Dr., using proper grammar and vocabulary, and following established etiquette and protocol. Informal communication has no set rules or procedures and may allow for more flexibility in language use and behavior.

3) Structure: Formal communication is generally structured, organized, and planned. It may involve preparing written documents or presentations in advance, following a specific agenda, or adhering to a strict timeline. Informal communication can be spontaneous and unplanned, with no set structure or agenda.

4) Language: Formal communication uses proper grammar and vocabulary, avoiding slang, colloquial language, or jargon. Informal communication may use more relaxed or casual language, including slang, colloquialisms, or jargon, depending on the context.

5) Information Delivery: Formal communication conveys information clearly and concisely, often prioritizing accuracy and professionalism over a personal connection or entertainment value. Informal communication may use storytelling, humor, or other techniques to convey information, and may prioritize personal connection or entertainment value over accuracy or professionalism.

6) Mode of Communication: Formal communication is often written, such as in emails, business reports, or presented through formal speeches or presentations. Informal communication is often spoken, such as in conversations or phone calls, but can also take written form, such as through text messages or social media.

7) Greetings and Sign-Offs: In formal communication, formal greetings and sign-offs are used, such as “Dear Sir/Madam” and “Sincerely.” In informal communication, casual greetings and sign-offs are used, such as “Hey” or “Take care.”

8) Personal Topics: Formal communication typically avoids personal topics or opinions, focusing on professional or official information. Informal communication may include personal opinions, experiences, or topics unrelated to professional or official matters.

9) Tone: Formal communication tends to be serious and professional, with a focus on conveying information respectfully and objectively. Informal communication tends to be more lighthearted and relaxed, with a focus on personal connection and emotional expression.

10) Etiquette and Protocol: Formal communication requires attention to etiquette and protocol, including adherence to established rules and procedures related to behavior, language use, and other social norms. Informal communication may require little attention to etiquette or protocol and may prioritize personal comfort or spontaneity over strict adherence to social norms.

Advantages and disadvantages of informal communication

Two advantages of informal communication are:

1. Speed: Informal communication can be faster than formal communication since it doesn’t have to go through the organizational hierarchy. It allows information to be quickly disseminated among employees.

2. Flexibility: Compared to formal communication, informal communication is characterized by greater flexibility. It allows employees to communicate in a way that is more comfortable for them, such as using informal language, which can help build stronger relationships and foster collaboration.

Two disadvantages of informal communication are:

1. Inaccuracy: Since informal communication isn’t regulated or controlled, there’s a higher chance that information may be inaccurate, incomplete, or distorted as it is passed along. This can lead to confusion and misunderstandings among employees.

2. Lack of documentation: Informal communication is usually not documented, which can make it difficult to track important decisions or actions taken based on that communication. This can create legal or financial issues for an organization if there’s a need to provide evidence of communication or decisions made.

What is the implication of informal communication? 

Informal communication, whether in personal or organizational settings, can have significant implications for relationships, productivity, and decision-making. While it can facilitate the flow of information and build trust and collaboration, it can also lead to inaccuracies, misunderstandings, and the spread of rumors or gossip, commonly known as the “grapevine”.

By discussing issues in an informal setting, employees can often come to a resolution without the need for formal mediation.

Practical tips & strategies for both formal and informal settings

Based on our own experience and expertise below we have drafted three practical tips and strategies for communicating effectively while using formal and informal communication. 

Tips for Effective Formal Communication:

1) Prepare ahead of time: Before engaging in formal communication, it’s important to prepare your thoughts and what you want to communicate. This could involve researching the topic, making an outline of your ideas, and reviewing the principles of good communication

2) Be mindful of your tone: Your tone can impact how your message is received. In formal communication, it’s important to use a professional and respectful tone, even if you’re discussing difficult or contentious topics.

3) Stay focused on the topic: It’s easy to get sidetracked during formal communication, but it’s important to stay focused on the topic at hand. Avoid going off on tangents and bring the conversation back to the main point if it begins to stray.

Tips for Effective Informal Communication:

1) Be personable and approachable: When communicating informally, it’s important to be personable and approachable. This can help to create a relaxed and friendly atmosphere, which can make communication easier and more effective.

2) Listen actively: Effective informal communication requires active listening. Make sure to listen to what the other person is saying and respond appropriately.

3) Be mindful of nonverbal cues: In informal communication, nonverbal cues such as facial expressions and body language can be just as important as spoken words. Pay attention to these cues to better understand the message being conveyed.

By following these tips and strategies, you can communicate effectively in both formal and informal settings, building stronger relationships with your colleagues, friends, and family.
