Final answer:
Cannibalization concerns are typically addressed in the business analysis phase of the new-product development process, where the impact of a new product on existing lines and financial projections is closely examined.
Step-by-step explanation:
Concerns about cannibalization of current product sales must be addressed in the business analysis phase of the new-product development process. During business analysis, a detailed investigation takes place, assessing the potential effect of the new product on existing product lines, market demand, overall business strategy, and financial forecasts. This stage involves examining sales volumes, pricing, market share, and profitability to ensure the new product will be a valuable addition without significantly deterring sales from the company's existing products. The concept of cannibalization is vital in this step, as it considers how the new product might take sales away from the company's current offerings, which can be a major concern when launching a new product within the same market space.
