What are the advantages and disadvantages of lengthening the product line?

Lengthening the product line can offer advantages such as increased market reach, the ability to cater to diverse customer preferences, and potential economies of scale in production. However, it also comes with disadvantages, including the risk of brand dilution, increased complexity in inventory management, and the potential for cannibalization of existing products. Companies must carefully balance these factors to ensure that extending their product line aligns with overall strategic goals.
