Written Communication Skills
From the Communication skills curriculum
TL;DR
Good written communication helps you share your message clearly and effectively, so your reader understands exactly what you mean. It's about being clear, concise, and considering your audience. Mastering this skill makes you more impactful in all your communications, from emails to reports.
1. The Mental Model
Think of writing as building a bridge between your thoughts and your reader's mind. Your goal is to make that bridge sturdy and easy to cross, so your message travels smoothly without any confusion or misinterpretation.
2. The Core Material
Understanding Your Audience

Before you write anything, consider who you're writing to. What do they already know? What do they need to know? What's their relationship with you? Tailoring your language, tone, and level of detail to your audience ensures your message resonates and is understood. For example, you'd explain something differently to a colleague than to a client.
Clarity and Conciseness
These are the cornerstones of effective written communication.
* Clarity means your message is easy to understand. Avoid jargon, overly complex sentences, and ambiguous words. Get straight to the point.
* Conciseness means using as few words as possible without losing meaning. Cut out filler words and redundant phrases. Every word should add value.
Structure and Organization

Well-structured writing guides your reader through your ideas logically.
- Introduction: Briefly state the purpose of your communication. What will the reader learn or gain?
- Body Paragraphs: Each paragraph should focus on a single main idea, supported by details or examples. Use topic sentences to introduce the main idea of each paragraph.
- Conclusion: Summarize your main points and, if applicable, state next steps or a call to action.
Use headings, subheadings, bullet points, and numbered lists to break up text and make it easier to scan and digest.
Tone
Your tone conveys your attitude towards your subject and your reader. It can be formal, informal, serious, humorous, empathetic, etc. Match your tone to your purpose and audience. For professional communication, a respectful, clear, and confident tone is usually best.
Proofreading and Editing

Don't underestimate the power of a final review. Errors in grammar, spelling, or punctuation can undermine your credibility. Read through your work carefully, or even better, ask someone else to review it. Reading aloud can help you catch awkward phrasing.
Here's a simple process for effective written communication:
graph TD
A["Identify Audience & Purpose"] --> B["Outline Key Points"]
B --> C["Draft Your Message"]
C --> D{"Review for Clarity & Conciseness"}
D -- Yes --> E{"Check Tone & Structure"}
E -- Yes --> F{"Proofread for Errors"}
F -- Yes --> G["Send/Publish"]
D -- No --> C
E -- No --> C
F -- No --> C
3. Worked Example
Let's say you need to write an email to your team about a new project management software.
Poor Example:
Subject: Software Update
Hi Team,
Just letting you know we're using a new PM tool. It's called "QuantumFlow." It has a lot of features. You should check it out. We'll start using it next week. Any questions, let me know.
Thanks,
[Your Name]
Critique: This email is vague. It doesn't tell the team why they're using a new tool, what its benefits are, how to use it, or when training will happen. The tone is very informal, and it creates more questions than answers.
Improved Example:
Subject: Important: Transitioning to QuantumFlow for Project Management
Hi Team,
To enhance our project collaboration and efficiency, we're transitioning to a new project management software, QuantumFlow, starting next Monday, October 23rd.
QuantumFlow offers several key benefits:
* Centralized Task Tracking: All project tasks will be in one place, making it easier to see who's working on what.
* Improved Communication: You can comment directly on tasks and projects, streamlining discussions.
* Better Reporting: This will help us track project progress more effectively.
We'll be holding a mandatory training session on Thursday, October 19th, from 10:00 AM - 11:00 AM in Conference Room B. Please mark your calendars. I'll send a calendar invite shortly.
In the meantime, you can access QuantumFlow here: [Link to software]. Your login details will be sent separately.
Please reach out to me if you have any immediate questions.
Best regards,
[Your Name]
Why it's better: It clearly states the purpose (enhance collaboration), introduces the new tool, highlights its benefits, provides clear next steps (training date/time), and includes a call to action (attend training, ask questions). It's well-structured with bullet points and a professional yet friendly tone.
4. Key Takeaways
- Always think about your audience and the purpose of your communication before you start writing.
- Aim for clarity by using simple, direct language and avoiding jargon.
- Be concise; every word should earn its place in your writing.
- Structure your message logically with a clear introduction, body, and conclusion.
- Choose an appropriate tone that matches your message and audience.
- Always proofread carefully to catch any errors and maintain your credibility.
Common Mistakes to Avoid:
- Not proofreading, leading to embarrassing typos or grammatical errors.
- Using overly complex vocabulary or jargon that alienates your reader.
- Failing to clearly state the main purpose or call to action.
- Writing long, dense paragraphs without breaks, making text hard to read.
5. Now Try It
Take five minutes to outline an email you need to send soon (e.g., to a professor about an extension, to a colleague about a meeting, or to a friend about planning an event). Focus on identifying your audience, your core message, and the key points you'd include. Then, draft the email, keeping clarity, conciseness, and tone in mind. Once drafted, read it aloud to yourself to catch any awkward phrasing or unclear sentences. You'll know you've succeeded if your email clearly communicates your message and any necessary actions in a straightforward, professional way.
