Explain the following: "product line," "product length," "product width," "product depth?"

These terms relate to the product offering by a company,
especially if the company manufactures a large number of different products (including
similar products).

Product
Line: products of similar nature, price, function, intended market, etc.
form a product line. It is different from product bundling where similar products are
bundled and sold together as a unit. A product line comprises similar products that are
sold separately. A company can have a number of product lines. For example, Toyota has a
product line of sedans, a product line of SUVs and a product line of pick-up trucks. In
the product line of sedans, Toyota offers Corolla, Camry, Avalon,
etc.

Product Length: refers to
total number of products sold within a product line. For example, Asus may have 10
different types of netbooks.

Product
Width: refers to number of separate product lines offered by a company.
For example, the product width of Toyota may be 3, one each for product lines of sedans,
pick-ups and SUVs.

Product
Depth: refers to the number of sub-categories within a product line. For
example, Adidas may have 5 different sub-classes (say basketball shoes, athletics shoes,
tennis shoes, etc.) within the product line of sports shoes.
