This is a skill that is best demonstrated. You could ask staff whether they believe TIC is needed, however, the essence of this action is whether they can explain it to others. To that end, look for ways to incorporate explanation into a normal routine. For example, staff could work together to develop an elevator speech or short explanation. Then they could pair up and practice their explanations. The more they talk about what TIC is and why it’s important, the easier this will be.
