A message does not travel unchanged from one mind to another. It is shaped by wording, channel, and the receiver’s experience. Understanding the system lets you intervene before an error appears.

Encoding turns an intention into words, structure, tone, and gestures; decoding assigns meaning. “Let’s look at it soon” may mean today to one person and next week to another.

For a change, state the fact, give context, explain impact, and ask for confirmation. At NexoLab: “The demo moves from Tuesday to Thursday because testing needs two more days. Can you confirm by 16:00 whether this affects any delivery?”

• Assuming context. State the essential background.
• Sending the same text to every audience. Separate operational and decision information.
• Treating acknowledgement as understanding. “Received” does not confirm agreement or capacity to act.

1. Break down a real work announcement into sender, receivers, message, channel, context, and feedback.
2. Write a question that would reveal scheduling conflicts.

1. Identify which element you failed to design; a process change may need operational owners and informed people.
2. “Please identify by 16:00 any task affected by the demo change and the adjustment you propose.”

Sender, receiver, message, channel, context, and feedback form a system. Preparing them prevents correct information from producing the wrong action. Next, examine barriers that disrupt the system.
