SDE analysis in inventory management (abbreviated for scarce, difficult, and easy refers to the classification of inventory based on scarcity of supply. Let's look at the SDE classification in detail:
1. S-Scarce: It includes inventory rare to find within the regional boundaries. Such goods are limited in stock and are usually imported; hence, they take longer to arrive.
2. D-Difficult: This classification includes goods that are available domestically but are still limited and harder to arrange. The lead time of acquiring these goods is more than two weeks but less than six months.
3. E-Easy: It includes inventory that is readily available and high in supply. These items are available domestically and quickly arranged due to several suppliers in the market.
