Final answer:
In considering the manufacture of a new mousetrap, a manufacturer should prioritize cost efficiency to achieve long-term sustainability and profitability.
Step-by-step explanation:
The key factor that a manufacturer should prioritize in considering the manufacture of a new and better mousetrap is cost efficiency. This means focusing on minimizing production costs while maximizing quality and functionality. A cost-efficient mousetrap allows the manufacturer to offer competitive prices while maintaining profitability.
A manufacturer can achieve cost efficiency through various means, such as optimizing the manufacturing process, sourcing affordable materials, and minimizing waste. By analyzing the cost implications of different design choices and production methods, the manufacturer can make informed decisions that lead to a more cost-efficient mousetrap.
It's important to note that while other factors like material color and aesthetic design may contribute to consumer preferences and market appeal, cost efficiency should take precedence to ensure long-term sustainability and profitability for the manufacturer.
