Best Practices

Before Sending

  • [ ] Clear subject line
  • [ ] Correct recipients
  • [ ] Appropriate tone
  • [ ] Grammar and spelling checked

  • [ ] Attachments included
  • [ ] Call to action clear
  • [ ] Read out loud for flow

Common Mistakes to Avoid

  • Unclear Subject: "Update" or "Question" (too vague)
  • Missing Context: Jumping into request without background
  • Too Long: Multiple pages of text
  • No Action: Unclear what recipient should do
  • Poor Timing: Sending late Friday for Monday deadline
  • Wrong Tone: Too casual with executives, too formal with peers
  • Passive Voice: "Mistakes were made" vs "I made a mistake"
  • Jargon Overload: Acronyms and terms reader may not know

Research-Backed Communication Principles

Writing Competency in Professional Settings

Research on business communication (Hines & Basso, 2009) reveals critical findings about professional writing:

Grammar and clarity matter:

  • Entry-level professionals frequently lack thorough understanding of grammar, punctuation, and sentence structure
  • Passive voice weakens impact: "Mistakes were made" vs "We made mistakes" - active voice creates accountability
  • Subject-verb agreement errors: Most common when clauses/phrases separate subject and verb
  • Pronoun confusion: Misuse of I/me/myself reflects poorly on credibility

Business writing principles:

  • Logical conclusion first: Busy executives need the point upfront (not buried in middle/end)
  • Clear and concise prose: Enables quick processing of message meaning
  • Expressive vs. elitist language: Write to express ideas, not to impress with complexity
  • Plain language initiative: Government and corporate push for clarity and efficiency

Evidence-Based Takeaway: Grammatical competency forges trust. Proper grammar avoids ambiguity and demonstrates professionalism.

Effective Workplace Communication

Research on great workplaces (Great Place to Work Institute, 2011) demonstrates communication's impact:

Communication affects credibility:

  • Good communication skills invite two-way dialogue
  • Clear and informative managers reduce rumor spread
  • Accessible managers allow employees to get needed information
  • Open communication allows employees to meet expectations and be productive

Generational communication differences:

  • Traditionalists/Baby Boomers: Prefer one-to-one communication
  • Gen X: Want work calls only, respond to open-ended questions
  • Millennials: Use online social media, expect frequent feedback, prefer teams

Best practice: At team formation, learn how members prefer to communicate. Bring everyone onto the same page for optimal productivity.

Interpersonal Communication Quality

Research on workplace communication (Newson, 2010) highlights:

Key elements of effective interpersonal communication:

  1. Self-awareness: Understanding your own communication style and biases
  2. Attentive listening: More than hearing words - observing reactions and tone
  3. Sensitivity to others: Recognizing emotional state and context
  4. Strategic silence: Allowing space for reflection and processing

The power of silence:

  • Gives speakers time to think and feel
  • Creates space for reflection and problem-solving
  • In grief/difficult news, presence matters more than words
  • Uncomfortable at first, but powerful when mastered

Practical Application: In difficult email conversations, sometimes less is more. Know when brevity and directness serve better than lengthy explanations.
