Answer:
c. They account for a larger dollar value than class C items
Step-by-step explanation:
The ABC inventory analysis is a method of classifying inventory in three main groups: A, B and C, where group A items include items that are most valuable and group C items the least valuable ones.
Conceptually similar to the Pareto principle, this method revolves around the fact businesses should focus on a limited scope of products, services or procedures that bring the most profit in comparison to other products/services.
Since group A items are critical to supply chain success, they require close monitoring by the operations managers and are rarely managed by wholly automated systems.
Like in the Pareto principle, A items usually have 10-20% share in the total item share, while they bring 70-80% of total profit.
