Nancy is a manager for a quick$-$service restaurant that is part of a national chain with over $180$ units throughout the United States. While searching through the mail from the main office, she found a letter reminding managers to order new menu boards for their units. A nutrition analysis had been done on new menu items, and the menu boards were scheduled to be updated to reflect the changes.

Nancy thought these directives from the main office increased expenses for the unit without a very good reason. She thought customers paid no attention to calories anyway. "What was all the fuss about anyhow?" Nancy put the reminder at the back of her $"$to$-$do$"$ pile thinking she would just skip the new boards and save the unit money.

What did Nancy not consider in her decision to postpone changing menu boards?

What are the potential issues she may have created with her decision?
