CQualities

The 8 C Qualities of Professional Communication

The “C Qualities” are a set of attributes that effective professional writing and communication should demonstrate. Business writing is traditionally described as needing 3 Cs (clear, concise, correct); this framework expands to 8.

How It Appears Per Course

ADMN 233

Core framework from “Professional Communication Style And Tone” (Dr. Glen Farrelly). Applies to all written and oral professional communication — emails, reports, presentations, and informal discussions.

#	Quality	One-line definition
1	Compelling	Relevant and goal-oriented; state the topic and “the ask” early
2	Clear	Audience can easily understand; define terms, avoid ambiguity
3	Correct	Grammatically and factually accurate; cite sources
4	Concise	Cut all non-essential words and ideas
5	Concrete	Use specific words and precise numbers instead of vague ones
6	Consistent	Same verb tense, perspective, spelling, and concept naming throughout
7	Courteous	Inclusive, bias-free, appropriate reading level
8	Credible	Formal register and positive tone; supports claims with evidence

Detailed Notes

1. Compelling

• “The ask” = the action item you want the audience to take; never make them guess it
• Use active voice (Raj wrote the report vs. The report was written by Raj)
• Use first/second person (“I,” “you,” “we”); avoid generic third person
• Write with audience focus: frame benefit to them, not to your organization
• Exception: passive voice is appropriate for diffusing responsibility (sensitive news)

2. Clear

• Define new terms on first use; spell out acronyms in full then abbreviate
• Avoid metaphors, symbolism, double negatives, ambiguous pronouns
• When clarity and conciseness conflict: always side with clarity

3. Correct

• Correct in two ways: grammatically and factually
• Use facts, not opinions; label opinions clearly when you must use them
• Cite all sources; plagiarism is both an ethical and legal problem
• Proofread extra carefully: names, numbers, dates, legal implications

4. Concise

• No repetition — say it once, well
• No tangents (off-topic) or filler (padding to length)
• Don’t tell people what they already know — calibrate to audience background
• Cut unnecessary words, cut lead-in phrases (“it is this,” “there are,” “in fact”)
• Favour short sentences (1–2 lines); favour short paragraphs (6–8 sentences max)
• See also Wordiness for the four specific types of wordiness to cut

5. Concrete

• Prefer specific words over abstract ones (“wet” vs. “odd”)
• Replace vague amounts: lots / many / several / few → actual numbers
• Use precise numbers for sales, complaints, costs, dates

6. Consistent

• Verb tense: pick one (past or present) and stick to it
• Perspective: don’t mix “you” and “one” in the same sentence/paragraph
• Spelling: pick one variant of variable words (email vs. e-mail) and use it throughout
• Concept naming: always use the same term for the same thing
• Follow organizational brand guidelines and style guides when available

7. Courteous

• Use common, everyday words (not complex words to impress)
• Match reading level to audience — too high = aloof; too low = condescending
• Use inclusive, bias-free language (see below)

Inclusive language (EDI — Equity, Diversity, Inclusion):

• “they” instead of “he or she”
• Use terminology the person prefers for their identity
• Describe disability neutrally: “uses a wheelchair” not “confined to a wheelchair”
• Avoid cultural assumptions and idioms that may confuse international readers
• Use accents on French words

8. Credible

• Adopt a formal register as the default; start formal, relax as rapport builds
• Register = vocabulary, sentence structure, contractions, humour, names
• Use positive language wherever possible (reframe negatives as positives)
• Build credibility through facts, logic, and concrete data — not just assertions

Bonus C Qualities

Complete — all necessary details included
Coherent — ideas flow logically with transitions
Confident — project belief in your position (especially for persuasion)
Context — consider timing, sensitivity, socio-political climate
Conclusion — every professional message must wrap up elegantly

Connection to the 4 Cs of Editing

The WritingProcess reading introduced 4 Cs for the Revising step (editing). Those 4 Cs (Complete, Concise, Coherent, Clear) are a subset of the broader 8 C Qualities framework here. Knowing both is important — they are tested differently.

Key Points for Exam/Study

• There are 8 primary C Qualities + bonus Cs (Complete, Coherent, Confident, Context, Conclusion)
• “The ask” is a key term from Compelling — always state what you want the reader to do
• Active voice = preferred; passive voice = useful for sensitive/negative information only
• Audience focus: “As a repeat customer, you will enjoy discounts” vs. “We offer discounts”
• Clear always beats concise when they conflict
• Inclusive language = EDI; use “they” not “he or she”; neutral disability language
• Register = formality level; when in doubt, be more formal
• Positive tone = reframe negative information as positive where possible

Cross-Course Connections

WritingProcess — the 4 Cs of editing are a subset of these 8 Cs
Wordiness — the Concise C specifically addresses wordiness
AudienceAnalysis — Compelling (1.3) and Courteous (7) both require deep audience knowledge
Argument — Correct and Credible map to argumentation’s emphasis on evidence, facts, and avoiding fallacious reasoning
