Communication principles
Last updated: November 2026. Published by Beltway Media.
The 7 C's of communication are clear, concise, concrete, correct, coherent, complete and courteous.
The Communications Checklist, published by Beltway Media, turns each C into a yes or no test you can run on any email, statement or speech before it goes out. The 5 C's and 10 C's are shorter and longer versions of the same idea, and lists vary between textbooks and trainers.
Part of the master communications checklist. Start there for the full 24-item framework.
| Principle | Checklist test |
|---|---|
| Clear | Could someone outside your team restate the main point after one read? |
| Concise | Have you cut every sentence that does not support the main point? |
| Concrete | Does it use specific facts, names and numbers instead of general claims? |
| Correct | Are facts, figures, names and grammar verified? |
| Coherent | Does each point follow logically from the one before it? |
| Complete | Does the reader know what to do next, by when, and who to contact? |
| Courteous | Is the tone respectful of the reader, even when the news is bad? |
A common version of the 5 C's of communication is clear, concise, concrete, correct and courteous. Some trainers swap in complete or coherent. The five-item list is a fast pre-send check for everyday messages: is it easy to understand, short, specific, accurate and respectful?
The 10 C's are not standardized. Most lists take the 7 C's and add three such as consistent, credible and considerate. For organizations, consistent is the one that matters most: the same message must hold across executives, channels and audiences, which is why the master communications checklist asks you to state your position in one sentence.
Seven practical tips for effective communication, each tied to a checklist item on this site:
Tips 5 and 6 are backed by published figures: 54% of employees say they often leave meetings without knowing next steps or who is responsible (Zoom), and employees give 7% more attention to emails from individual leaders than from shared mailboxes (PoliteMail).
The Cs test a single message. Beltway Mediauses its Four Languages Model to plan across every touchpoint: how audiences read, see, hear and experience content, and how each language amplifies the others. Combined with data-driven strategy and behavioral science, it aims to connect with audiences on a deeper, more psychological level. The firm's view is that people do read long-form content when it is relevant, valuable and loads quickly.
A common version of the 5 C's of communication is clear, concise, concrete, correct and courteous. Different textbooks and trainers swap in words such as complete or coherent, so there is no single official list. The idea is the same: a message should be easy to understand, brief, specific, accurate and respectful.
The 7 C's of communication are usually listed as clear, concise, concrete, correct, coherent, complete and courteous. Some versions use considerate or credible in place of one item. Each C works as a quick checklist test before a message goes out, which is why the principles page on this site turns all seven into yes or no questions.
The 10 C's of effective communication are not standardized. Most lists start with the 7 C's (clear, concise, concrete, correct, coherent, complete, courteous) and add three such as consistent, credible and considerate. Consistency matters most for organizations, because the same message has to hold across leaders, channels and audiences over time.
There is no single official list, but ten widely taught principles are: know your audience, lead with one main message, be clear, be brief, stay consistent, listen as much as you speak, choose the right timing, use the right channel, stay credible, and follow up with clear next steps and owners.
Ten communication skills most often cited are active listening, clarity, brevity, empathy, confidence, adapting to the audience, storytelling, writing, giving and receiving feedback, and staying calm under pressure. For leaders, spokesperson skills matter too. Beltway Media includes media training and spokesperson development in its fractional chief communications officer service.
Group your improvements into four areas: listening (pause, paraphrase, ask questions), writing (lead with the point, cut words, read it aloud), speaking (rehearse, slow down, use stories) and follow-through (summarize decisions, name owners, confirm dates). Practicing five habits in each area gives you twenty concrete improvements you can track on a simple checklist.
Seven practical tips: put the main point first, write for one specific audience, cut jargon, use one call to action, confirm next steps and owners before a meeting ends, send important messages from a named leader rather than a shared inbox, and ask for feedback. Published benchmarks suggest the last two points measurably change attention.
Keeping one message consistent across leaders and channels is the core job of a chief communications officer. Talk to Beltway Media in a free consultation.
