(d) Write a Design Specification for a product that will meet the design brief

• a design specification that defines the product to meet the design brief, considering: human factors; aesthetic factors; technical factors;  environmental factors

• each point of your design specification should be fully justified against your design brief, with references to your completed research

Below is the guidance in writing your Design Specification, which must include the following Sub Sections - Human factors, Aesthetic factors, Technical factors, Environmental factors.  

This is the most important section. Specifications must be SMART:

• Specific: Clearly defined, no ambiguity.

• Measurable: Can be objectively tested and evaluated.

• Achievable: Possible within the constraints of the project.

• Relevant: Directly relates to the problem and brief.

• Time-bound: Can be completed within the project timescale.

When writing a design specification for a new product, aesthetic factors are essential because they directly affect how appealing and desirable the product is to the target user. Aesthetics go beyond just appearance, they also influence how users emotionally respond to the product and whether it aligns with current trends or expectations

These factors help ensure the product not only functions well but also attracts the user, enhances brand value, and meets the emotional goals of the design brief.

When writing a design specification to define a new product, technical factors ensure that the product performs its intended function safely, efficiently, and reliably. These factors relate to how the product is made, how it works, and how it meets engineering or performance requirements.

These technical factors ensure the product is feasible to make, safe to use, and reliable over time. They also help align your design with the expectations in your brief and any limitations you are working within.

When writing a design specification, environmental factors are critical to ensure the product is sustainable and responsible throughout its entire lifecycle , from material sourcing to disposal. These factors show awareness of the product’s impact on the planet and align with ethical and legislative expectations.
