We focus this chapter on the task of establishing the product architecture. The purpose of the product architecture is to define the basic physical building blocks of the product in terms of what they do and what their interfaces are to the rest of the device. Ebook Product design and development (6/E): Part 2 Architectural decisions allow the detailed design and testing of these building blocks to be assigned to teams, individuals, and/or suppliers, such tEbook Product design and development (6/E): Part 2

We then present a method for establishing the product architecture and focus on the printer example for illustration. (Note that the details of the printer example have been somewhat disguised to preserve Hewlett-Packard’s proprietary product information.) After presenting the method, we discuss Ebook Product design and development (6/E): Part 2 the relationships among product architecture, product variety, and supply-chain performance. and we provide guidance for platform planning, an activiEbook Product design and development (6/E): Part 2

The funcwww.downloadslide.netCHAPTER TENProduct ArchitectureCxMirtwy of Hcukii-RKkanl CnmpMtyEXHIBIT 10-1Three Hewlett-Packard printers from the same product Ebook Product design and development (6/E): Part 2r, some of the functional elements are "store paper'* and "communicate with host computer." Functional elements are usually described in schematic form before they are reduced to specific technologies, components, or physical working principles.The physical elements of a product are the parts, compo Ebook Product design and development (6/E): Part 2nents, and subassemblies that ultimately implement the product's functions.

Each chunk is then made up of a collection of components th Ebook Product design and development (6/E): Part 2at implement the functions of the product. The architecture of a product is the scheme by which the functional elements of the product arc arranged inEbook Product design and development (6/E): Part 2
to physical chunks and by which the chunks interact.Perhaps the most important characteristic of a product’s architecture is its modularity. Consider www.downloadslide.netCHAPTER TENProduct ArchitectureCxMirtwy of Hcukii-RKkanl CnmpMtyEXHIBIT 10-1Three Hewlett-Packard printers from the same product Ebook Product design and development (6/E): Part 2n and the brake control function are allocated to separate chunks, which in fact are mounted in separate locations on the bicycle. This design exhibits a modular architecture. In the design on the right, the shift and brake control functions arc allocated to the same chunk. This design exhibits an i Ebook Product design and development (6/E): Part 2ntegral architecture—in this case motivated by aerodynamic and ergonomic concerns.A modular architecture has the following two properties:•Chunks implEbook Product design and development (6/E): Part 2

Such a modular architecture allows a design change to be made to one chunk without requiring a change to other chunks for the product to function correctly. The chunks may also be designed quite independently of one an Ebook Product design and development (6/E): Part 2other.The opposite of a modular architecture is an integral architecture.
