Which items are denoted by a stop sign in the system?

In the system, a stop sign is used to denote both required and recommended items. This visual cue is important because it quickly alerts users to items that need attention or action. Required items must be addressed for processes to move forward, while recommended items provide guidance or suggestions that enhance workflow or outcomes. By indicating both types of items with a stop sign, users can prioritize their tasks effectively, ensuring that critical components are not overlooked while still having awareness of additional recommendations that could improve their work. Understanding the significance of this system visual helps in efficiently navigating tasks and managing priorities.
