What does it represent?
The service level indicates the delivery reliability of a product or supplier. In other words, what percentage of the products were or will be delivered from stock? The higher the service level, the more products could be delivered from stock.
Service level per product
You will find the service level per product on the 'Product details' page in Optiply. This indicates for each product how many days it was in stock in the last 30 days.
service level (product) = number of days in stock in past 30 days / 30
Service level by category
You can set the desired service level per category on the 'General Settings' and 'Dashboard' pages in Optiply. Optiply divides products into an A/ B/ C category. More information about product categorisation can be found on the A.B.C. Category page.
The service level per category is an average of all individual service levels of the products from the corresponding category, weighted by their expected demand.
