Design Methods and Processes

Design for Functionality

Design specification refers to a detailed document outlining the intended functions, performance levels, materials, and aesthetics of the proposed design.
Functionality is central in design and revolving around the question of what the product is intended to do. Designers must ensure the design achieves its primary function without unnecessary complications.
Ergonomics and Human Factors relate to ensuring a design is efficient and comfortable for human use, taking into account physical interaction and psychological impacts.

Visual aesthetics play a key role in product packaging and presentation, significantly influencing the perception and success of a product.
Psychology of colour, pattern and texture can influence consumer decisions; thus it is important to consider colour schemes, patterns, and texture for aesthetically pleasing and effective designs.
Sensory design considers all human senses (not just sight) to create a full sensory experience and enhance the user’s engagement with the design.

Iterative design is a design methodology based on a cyclic process of prototyping, testing, refining, and evaluating a design.
Prototyping is creating sample or test versions of a design as part of the process for developing and refining final products.
Feedback plays a critical role in design methods and processes, as it gives a realistic view of how well a design functions and is perceived by users.

Design decisions need to be made regarding materials, production methods, and aesthetics. These decisions must be supported by justifiable reasoning, often involving trade-offs.
Ethical implications in design choices should be considered. This includes considerations concerning environmental impact, fair-trade production, and sustainable materials.
Design fix refers to a fixed or standard solution to a common problem or requirement in design. It is a tried-and-tested solution that designers can use, eliminating the need to reinvent a design component.
