When executives want to work on something in peace and not be disturbed, they close their office doors. On the sales floor, you don’t have a door to close, so what can you do?
In the second company I worked for, one of the most successful reps used to hang a “do not disturb” sign on the padding in his cube. It was in big, red letters and you couldn’t miss it. I heard that when he first put it up, some people used to ignore it and walk over and start talking to him. He wouldn’t answer. Instead he would simple point at the sign until they walked away.
Once everyone knew he was serious he rarely got any interruptions. In fact, the senior management at the company LOVED that he did this because they believed (rightly) that he was going to be more productive and would sell more (he did).
If you are going to implement this, a quick tip for you. Go round each of the senior managers in your vicinity and tell them what you are doing and ask for their support. If they agree, make sure they understand that even if they try and interrupt you, you will ignore them.
Action: try this for your next prospecting time block.
