What is one of the key elements of product design?

Function is a fundamental key element of product design because it directly pertains to how well a product serves its intended purpose. This includes aspects such as usability, practicality, and the overall performance of the product in real-world applications. For a product to succeed in the market, it must not only be visually appealing but also effectively meet the needs and expectations of its users.

Prioritizing function ensures that the product solves a specific problem or fulfills a particular need for consumers. Designers evaluate the product's functionality during the design process to ensure that it is user-friendly and efficient, ultimately contributing to customer satisfaction and product quality. A product that excels in function is more likely to capture and retain customer interest, leading to better sales performance.

While profit margin, market demand, and brand loyalty are important considerations in the overall business strategy, they are secondary to the immediate requirements of the product itself, which is primarily its function. If a product does not function well, no amount of brand loyalty or high profit margin will make it successful in the long term.
