Which of the following describes the width of a product mix?

The width of a product mix refers specifically to the total number of product lines that a company offers. A product line consists of related products that serve a similar purpose or functionality, and having a wider product mix with multiple lines allows a company to cater to different customer needs and preferences. This is a strategic aspect of product management that helps in diversifying offerings, targeting various market segments, and reducing the business risk associated with relying on a single product line.

In contrast, the total variations of a product would refer to the different versions or models of a single item, which relates more to the concept of product depth rather than mix width. The total number of products within a line also focuses on depth again, as it captures how many individual items are available under a specific product line. Lastly, the depth of product packaging is related to the packaging strategies or options associated with a product and does not pertain to the concept of product mix width. Understanding these definitions helps clarify why the total number of product lines is the appropriate measure of width in a product mix context.
