Abc Classification - What are the guidelines for ABC classification?

The ABC analysis is a tool for inventory management that sorts products according to how important they are for revenue generation and how much control measures are needed. The 20% of things that make up 80% of total income are represented by 'A,' which means that they require stringent monitoring. Thirty percent of the goods accounted for 15% of the revenue ('B'), whereas fifty percent of the things accounted for the least amount of income ('C').
