Which approach could potentially lower internal costs without sacrificing quality?

Redesigning a product for economical manufacture is the approach that could effectively lower internal costs while maintaining quality. This method involves analyzing the product's design and production process to identify areas where cost efficiencies can be achieved, such as using less expensive materials, simplifying the production methods, or altering the design to reduce labor costs. By doing so, companies can significantly reduce their production expenses without compromising the quality of the final product, as the focus remains on delivering a product that meets customer expectations.

In contrast, keeping existing practices stable may prevent any innovation or improvements that could lead to cost savings. Outsourcing all high-cost activities could introduce risks, including loss of control over product quality or the challenges of coordinating with external suppliers. Implementing aggressive strategic marketing, while potentially increasing market share or brand awareness, does not have a direct impact on reducing internal production costs. Therefore, redesigning for economical manufacture stands out as the most effective option for achieving lower costs alongside consistent quality.
