Unformatted text preview: The Design Process The design process involves organizing the creative and analytical processes used to satisfy a need or solve a problem. Sketches, drawings, computer models, and presentation graphics are all linked to the design and production process. Problem Identification Adequate time must be devoted to formulating design problems. Identifying the client. Interacting with the client. Market assessment. Need. Current situation. Goals. Brief, general and ideal response. How are we going to address this need? Objectives. Quantifiable expectations of performance. Are we meeting customer specifications? Constraints Third component of a problem statement. Define permissible range of the design and performance parameters. Attributes Any characteristic of a design. Not necessarily associated with either the need or any components of the problem statement. Criteria These are attributes of designs that are a basis for deciding among choices. Functions Services that must be preformed by the design. Concept Development Ideation Concept generation Explore thoroughly product concepts that may be applied to this problem. Concept selection Concepts are analyzed and sequentially eliminated. Refinement of specifications Revisit target specifications. Economic analysis An economic model is used to justify continuation of project. Project planning Must have a detailed development schedule. Adapting the Product Development Process Technology-Push Products Proprietary technology
Looks for an appropriate market. Match a new technology to a given market opportunity. Must have a clear competitive edge. Consumer Driven Aesthetics is very important. Focus groups. Customer surveys. Platform Products Pre-existing technology. Tape transport, computer operating system Hugh expenditures made to develop these technologies. Primary difference is that the technology has demonstrated it's usefulness. Process-Intensive Products Examples: Semiconductors, foods, chemicals, and paper. Strict constraints on the properties of the product. Customized Products Examples: Switches, motors, batteries, and containers. These are developed primarily by setting values of design variables. Design Selection Must narrow down field of possibilities. Carefully check to make sure that the requirement are being followed. Choose best solution.
