So, it's important that you explain the relevance of each person's job. Help each employee or team member to understand how what they do makes a difference.
Answer their questions about the significance of their work. Demonstrate how if their job isn't done well, or isn't fully completed, how that negatively impacts the rest of the process or your business' overall product or service.
Sometimes in organizations too much time is spent explaining the relevance of sales positions or management positions. But, everyone on the team needs to understand their relevance and the importance of what they do.
