When mass producing a new type of electric shaver, which of the following must be considered?

Finding a manufacturer is crucial when mass producing a new type of electric shaver because the manufacturing process is essential to transform the design and materials into a finished product that meets quality and safety standards. A manufacturer will have the facilities, equipment, and expertise needed to produce the shaver at scale efficiently, ensuring that the product can be delivered to the market in the required quantities and timeframes.

Additionally, a reliable manufacturer can help with optimizing production costs and may provide insights into materials and technologies that can enhance the product's features or durability. This step is fundamental in the overall product development process, as it directly impacts the supply chain, cost management, and the ability to fulfill demand once the product is launched. Other options, while potentially important in the broader context of launching a product, do not directly address the immediate need for production capabilities.
