- “supports”
- “helps drive”
Example:
“Cross-functional collaboration is essential to successful project delivery.”
With Clients
Client communication should remain clear and respectful.

Avoid overly academic expressions if the client prefers straightforward communication.

Common Mistakes to Avoid
1. Overusing “Important”
If every sentence says something is “important,” your writing can become repetitive.
Instead of:
“Communication plays an important role in teamwork. Leadership also plays an important role in teamwork.”
Try:
“Communication supports effective teamwork, while strong leadership helps drive performance.”
2. Choosing a Phrase That Is Too Strong
Do not use “critical,” “essential,” or “vital” unless the situation truly requires that level of importance.
For moderate importance, use:
“contributes significantly to”
or:
“supports.”
3. Using Corporate Language Unnecessarily
“Underpin” and “instrumental” are useful, but they can sound too formal in a simple email.
For example, a colleague may prefer:
“Your feedback really helped improve the proposal.”
rather than:
“Your feedback was instrumental in facilitating the optimization of the proposal.”
4. Ignoring the Subject of the Sentence
Some alternatives describe influence, while others describe contribution.
Compare:
“The marketing team contributes significantly to revenue growth.”
with:
“Market trends significantly influence revenue growth.”
The first focuses on contribution. The second focuses on influence.
5. Repeating the Same Phrase
Strong workplace communication varies wording naturally. However, do not replace every instance just to sound sophisticated. “Play an important role” is already correct.
