Final answer:
The key requirements within the design brief influence the preparation of the design specification by outlining the goals and constraints of the design solution. The design brief also helps guide the overall project plan by providing a roadmap for achieving the project goals within the specified timeframe.
Step-by-step explanation:
The key requirements within the design brief are the essential elements and main functions of the product or design solution. These requirements provide the foundation for the design specification, which is a detailed description of how the product will be designed and implemented. The design brief influences the preparation of the design specification by outlining the specific goals, objectives, and constraints that the design solution must meet.
For example, if the design brief is for a new smartphone, the key requirements may include features such as a high-resolution camera, a fast processor, and a long battery life. These requirements would then be used to develop the design specification, which would provide more specific details on the technical specifications, dimensions, materials, and other aspects of the smartphone design.
The design brief also helps guide the overall project plan by outlining the activities and timeline for the design process. It ensures that the design team has a clear understanding of the project goals and constraints, and provides a roadmap for achieving those goals within the specified timeframe.
