Question 1 Steel Works’ products are high quality metal which answer to specific needs. Steel Works’ customers are divided in two categories:
- Customers of the custom division, which develops products for a single customer. This division has a small amount of customers but a lot of products.
- Customers of the specialty division (130 customers who consume 120 different products). The majority of the specialty customers are small (107 of the 130 are small).

According to the results below, we can see that DURAFLEX R15 has a high coefficient of variance which means that it is very difficult to forecast an inventory level based on an historic demand with high volatility. This is especially true when this product is manufactured by batches of 60 units.
