The appropriateness of a design refers to how well it suits its intended use, environment, and user group. It is important that the design aligns with the context and the specific requirements for which it is created.

The function of a product refers to how well it performs the tasks it was designed for. A well-designed product should effectively and efficiently fulfill its primary function.

Life-cycle analysis (LCA) evaluates the environmental impact of a product throughout its entire life span, from raw material extraction, manufacturing, use, and maintenance, to disposal or recycling. It's crucial for identifying and minimizing a product's environmental footprint.

Aesthetics refers to the visual appeal, style, and design language of the product. It plays a significant role in user perception, satisfaction, and desirability.

Finance relates to the budget available for the design and production of the product. The financial constraints often dictate the materials, manufacturing processes, and technologies that can be used.

Obsolescence refers to the risk that a product may become outdated or irrelevant due to changes in technology, user preferences, or market trends. Designing for obsolescence involves ensuring the product can either be updated or remains useful over time.

Environmental consequences refer to the impact a product has on the environment throughout its lifecycle. Designers are increasingly focused on minimizing the environmental impact, whether through sustainable materials, energy-efficient manufacturing, or reduced waste.

Quality refers to the durability, reliability, and overall performance of the product. High-quality designs tend to enhance user satisfaction, longevity, and brand loyalty.

Work health and safety ensures that the design doesn’t pose any risks to the people using or interacting with it, whether in a workplace or consumer context. For products used in manufacturing, construction, or other industries, safety standards are essential.

Ergonomics involves designing products to fit the user’s physical needs, making them comfortable, efficient, and safe to use. The goal is to reduce strain, injury, and fatigue during product use.
