 To understand where technology ‘comes from’, what drives the innovation process, is of importance not only to those who are curious to understand the phenomenon of technology itself but also to those who are concerned about its role in society. Technology or engineering as a practice is concerned with the creation of artifacts and, of increasing importance, artifact-based services. The design process, the structured process leading toward that goal, forms the core of the practice of technology. In the engineering literature, the design process is commonly represented as consisting of a series of translational steps; see for this, e.g., Suh 2001. At the start are the customer’s needs or wishes. In the first step these are translated into a list of functional requirements, which then define the design task an engineer, or a team of engineers, has to accomplish. The functional requirements specify as precisely as possible what the device to be designed must be able to do. This step is required because customers usually focus on just one or two features and are unable to articulate the requirements that are necessary to support the functionality they desire. In the second step, the functional requirements are translated into design specifications, which the exact physical parameters of crucial components by which the functional requirements are going to be met. The design parameters chosen to satisfy these requirements are combined and made more precise such that a blueprint of the device results. The blueprint contains all the details that must be known such that the final step to the process of manufacturing the device can take place. It is tempting to consider the blueprint as the end result of a design process, instead of a finished copy being this result. However, actual copies of a device are crucial for the purpose of prototyping and testing. Prototyping and testing presuppose that the sequence of steps making up the design process can and will often contain iterations, leading to revisions of the design parameters and/or the functional requirements. Even though, certainly for mass-produced items, the manufacture of a product for delivery to its customers or to the market comes after the closure of the design phase, the manufacturing process is often reflected in the functional requirements of a device, for example in putting restrictions on the number of different components of which the device consists. The complexity of a device will affect how difficult it will be to maintain or repair it, and ease of maintenance or low repair costs are often functional requirements. An important modern development is that the complete life cycle of an artifact is now considered to be the designing engineer’s concern, up till the final stages of the recycling and disposal of its components and materials, and the functional requirements of any device should reflect this. From this point of view, neither a blueprint nor a prototype can be considered the end product of engineering design.
