Setting expectations up front for this kind of behaviour is great. Without a &#x27;culture&#x27; for allowing people to stay focused without an immediate interruption, I have always found it hard to explain to people interrupting me why they could have used an asynchronous communication tool, like Slack&#x2F;HipChat&#x2F;email, for non-urgent questions.
