A-B-C is a simple method used to categorize items or tasks based on their importance or priority. The "A" category includes the most critical items that require immediate attention, while "B" items are important but not urgent. Finally, "C" items are the least important and can be addressed later. This system helps individuals and organizations manage their time and resources effectively. The A-B-C method is commonly used in various fields, including business, education, and personal productivity. By organizing tasks in this way, people can focus on what truly matters, leading to improved efficiency and better decision-making.
