Effective communication is not simply fluent speaking or sending many messages. It means that the right people understand what is happening, why it matters, and what they can do next.

NexoLab is a fictional company preparing to launch a service. Irene coordinates design, development, and customer support; its case gives us safe material for practising conversations, meetings, and writing.

Before choosing words, decide whether you need to inform, request a decision, agree a criterion, or activate a task. “There are launch updates” gives no direction. “I need every owner to confirm by Thursday whether they can take their assigned tasks” gives an action, owner, and deadline.

1. What must the other person understand?
2. What decision or action do I need?
3. What do they already know?
4. Which channel fits the need?
5. How will I check shared understanding?

Feedback, confirmation, or paraphrase turns an assumption into verifiable understanding. Adapt detail to the audience and give the minimum useful context respectfully.

• Vague openings. Replace “when you can” with a deadline or priority criterion.
• Information without instruction. Make the expected action visible.
• Habitual channel choice. An urgent alert may need a call; a complex decision may need a document and short meeting.

1. Rewrite “We need to review the support issue for launch” with purpose, owner, and next step.
2. Identify the missing preparation question in a recent message that received no response.

1. “To prepare the 18 September launch, we need to agree support hours. Lucía, can you propose two coverage options by Wednesday?”
2. A clear request or deadline may have been missing; record one specific correction.

Starting with the result, adapting the message, and requesting verification reduce errors. The next lesson breaks down the system that makes shared understanding possible.
