The 3 C’s of Effective Business Communication How to be Clear, Concise and Complete

For more than 20 years I have been talking about the 3 C’s of effective communication. They are: clear, concise, and complete, and they are critical to making messages accessible to audiences. When someone uses the 3 C's as a guidepost to construct messages, emails, reports, letters, etc., they show that they possess a high level of competence as a communicator. Think for a moment to a time when you received either:

1. An unclear email — you had no idea what the other person needed or wanted;
2. A really long email with too much detail; and/or
3. An email that had a lot of information, but not the information you needed.

All of these scenarios can be frustrating for the receiver and negatively affect the credibility of the sender. That is why being clear, concise and complete in business writing makes such a positive difference for both the sender and the receiver.

Clear writing builds understanding

Clarity in writing and speaking can be challenging. If people do not have a good handle on their thoughts it is easy to take the message in numerous directions.

To make a message clearer:

• Consider what the purpose of the message is.
• Consider who the audience is and what matters to them.
• Start with a clear lead and get to the main point as soon as possible.
• If there is an ask, don’t bury it in the details; ask at the beginning of the message and then provide necessary details.
• Use subheadings to break up sections of content to make it easier to skim and process. (And, yes, you can and should use subheadings in longer emails.)

Concise writing builds goodwill

Almost anyone can be guilty of going on and on when writing about something they are passionate about. People also may share a lot of content because they feel all of it is necessary and have a hard time narrowing it down to the main points. Being concise is important in business communication because time is a finite resource and people do not like having their time wasted.

To make a message more concise:

• Consider who the audience is and what matters to them, and try to only focus your content on what they need to see.
• Ask yourself what the main points are for the content and focus on those so you do not overwhelm the receiver.
• Give the audience options on how much detailed information they receive by providing more detailed or extra information as supplemental materials.

Complete writing builds trust

Have you ever received an email inviting you to an event, but the date, location or time of the event was accidentally left off? You then either had to take time to ask for the missing information or wait until it was sent to you. Either way, because important information was left off the first time it may have eroded some of the trust you had about the sender’s competence.

Now, we are all human and we will make mistakes, but if this becomes a pattern for an individual that can become a major problem for their credibility. If someone is known for consistently leaving off important content in deliverables or not fully answering questions when replying to an email, then they most likely will be seen as someone who is unreliable. That is not a position in which any professional businessperson wants to find themselves.

To make a message more complete:

• Consider what the purpose of the message is — this will help you stay focused on necessary details the receiver may need.
• Consider who the audience is and what matters to them — different stakeholders may care about different aspects of a project or event — and consider what basic information to share to all and what extra information may be needed and appreciated by key stakeholders.
• Make a list of what information various stakeholders will need and then provide it.
• Once the content is written, review the list to make sure you are capturing everything your audience will need and want.

How AI can help you check for the 3 C’s

If what you are writing about does not include any confidential or proprietary information, then you can consider partnering with AI to help make your business writing clearer, as well as more concise and complete. With the right prompt you can ask AI to help you to check content for clarity, to make messages more concise, and to do a quality check to make sure you have included all necessary information. AI is very skilled at this type of consult and it can save you a lot of time on edits. Just keep in mind the best practice of always doing the final check of any content AI provides. Make sure your voice stays front and center, always.

Use the 3 C’s to build trust and credibility

The next time you are writing a message, email, report, etc., consider the 3 C’s and watch how over time the consistent use of them may change how you are viewed and seen by others.
