3. (a) How can Design for Environment (DFE) be effectively integrated into the standard product development process?
(b) A company is planning to launch a new product. They expect to sell 1,200 units at a price of $40 per unit. The fixed cost for producing the product is $12,000, and the variable cost per unit is $20. Based on this information, should the company move forward with the development of the new product? Justify your decision using break-even analysis.
(c) Write down the factors influencing a successful product design.
