What action does product mix width involve?

Product mix width pertains to the total number of different product lines a company offers. When discussing this concept, adding or removing a product line directly pertains to the breadth of the product mix. By expanding the width, a company introduces new product lines, thus enriching its offerings and potentially reaching a wider audience or addressing various market segments. Conversely, if a company decides to reduce its width, it may remove certain product lines that are underperforming or no longer align with the company's strategic direction.

On the other hand, increasing prices on multiple items, enhancing marketing strategies, or focusing solely on customer service do not directly influence the width of a product mix. These actions might pertain to pricing strategy, marketing effectiveness, or customer relationship management, respectively, but they do not relate to the number of different product lines available in a company’s assortment.
