Types of forecasting methodologies

Consider a scenario of a retailer. The retailer has the following two lines of product:

The first line of product (product line 1) comprises regular grocery items. The revenue from the first product line makes up 80% of the retailer's overall revenue.

The second line of product (product line 2) consists of special items such as branded mobile phones, laptops, cosmetic kits, television sets and bicycles. These special products are not always available in the retail store. The retailer ties up with international manufacturers of special items once in a week or two to bring these special products to stores at a heavily discounted price. The retailer always tries to surprise its customers by bringing in a different category of special products.

Now, there are two teams working to forecast the customer demands for the two product lines. Team 1 works for product line 1, and team 2 works for product line 2. You have learnt about the two types of forecasting methodologies, i.e., quantitative and qualitative. Based on your learnings, answer the following question.

Which type of forecasting method is more suitable for the products comprising product line 1?
