A replacement option is an optional part of a structure that, if selected, replaces some other part of the structure. A second type of option includes additional items in the structure if the option is selected, but does not specifically replace any other items. This type of option supports defining multiple models of the same end item each having a different BOM. For example, a 4-cylinder auto versus a 6-cylinder auto. Design options may include multiple changes to the product configuration such as 6-cylinder engine, 4-speed transmission, anti-lock brakes.

Used within process industries in a similar manner that product structure management is used within discrete industries. A recipe or formula defines the components of a product, how the product will be “assembled” and all the specifications and requirements associated with those products and their relationship and interdependencies. Also known as Formula Management and Recipe Management.
A European standard for the interchange of CAD/CAM data, particularly used in the aerospace industry.
An evolving international product data representation standard (ISO 10303). STEP is being designed top down to represent data from all aspects of the design and manufacturing processes and for different product types. STEP focuses on exchanging digital product models with sufficient information content so they can be interpreted directly by advanced CAD/CAM/CAE application programs. STEP will support a wide range of geometric and non-geometric data such as manufacturing features, tolerance specifications, material properties, configurations, specifications, and surface finish specifications. STEP is based on a neutral mechanism capable of completely representing product model data throughout the life cycle of a product.
An ISO standard (ISO 8879:1986) that provides a formal notation for the definition of generalized markup languages. HTML, SGML, and XML (Extensible Markup Language) provide for structuring and hypertext linking documents and database information in a vendor and computer-neutral, human-readable format.
The ANSI standard data access (query) language for relational database systems.
A part that is approved to be used in a specific design instead of a preferred part, if conditions warrant.
A computer-based system to manage data and processes about the lifecycle of the interaction between an organization and its suppliers, which can include requests for proposal, information, or quotation (RFP, RFI, RFQ), supplier qualification, and supplier quality management functions.
The person who sets up, manages, and customizes the PDM system to meet the enterprise’s needs.
The required performance, features, and characteristics of a complex system or product. These requirements lead to the system specification.
The act of designing a complex system that entails many components and subassemblies and involves several engineering disciplines.
A disciplined process that consists of describing behavior, selecting a component model of the architecture, and verifying that the required behavior is traceable from requirements and is feasible within the constraints upon time, cost, and component capabilities. An interdisciplinary approach and means for enabling the realization and deployment of successful systems. It can be viewed as the application of engineering techniques to the engineering of systems, as well as the application of a systems approach to engineering efforts.
Changing the defaults and options of a PDM system by setting preferences. Tailoring is done without writing or integrating code that modifies the PDM system.
A synonym for Product Data Management.
A synonym for Product Data Management.
A synonym for Product Data Management.
A design method that combines the use of divide-and-conquer techniques with one of adding increasing detail as the design processes. Top-down is typically used at the beginning of the design process.
See Bottom-Up Design
A broad approach to quality including product quality but extending well beyond to virtually everything done by an organization for external as well as “internal” customers (what marketing does for manufacturing for example) that encourages an enterprise-wide emphasis on quality and doing the job right the first time. Continuous improvement is sought toward measurable, ever-more-difficult quality targets.
A communication standard for connecting computing systems. It includes interactive, file, and mail interchange standards.
A mechanism that detects some activity, or change in state of some object in the PDM system and as a result, can initiate some subsequent action.
Synonym of version.
The PDM system’s computerized data storage area and databases. Information stored in PDM vaults are controlled by system rules and processes.
A variation of an approved and controlled item. Multiple versions of the same Revision Level may be created. Versions allow variations of components, configurations, and documents to be developed and used without requiring formal changes to the Revision or Baseline of an item.
Application used to display graphical objects, generally in raster format. Viewer applications allow users to zoom, pan, and otherwise modify the display of the object.
A standard that enables designers to create interactive, animated 3D virtual worlds that can be explored through various display technologies including virtual reality caves.
Systems that allow users to see all types of product data without having to have access to the data’s authoring application. This includes 3D CAD models, assemblies, drawings, and any type of documents. Typically these systems allow users to view, manipulate, annotate, and transmit data to other users. Some systems also allow users to create animations or simulations of product designs that can be viewed in motion.
Approval to deliver a product when it has been found during inspection or testing that a Configuration Item does not comply with the requirements of its technical documentation.
Waste Electrical and Electronic Equipment (WEEE) is a European Union directive intended to reduce the amount of electrical and electronic equipment being produced and to encourage its recovery, reuse, and recycling. The WEEE directive also intends to improve the environmental performance of businesses that manufacture, supply, use, recycle and recover electrical and electronic equipment. This directive is being adopted by many countries outside the EU.
A communication network that spans a large, geographically distributed, multi-site environment. WANs typically use protocols that provide higher transmission rates than LANs.
Used to plan and manage the process of developing a product design, to produce a product, and to support it. A WBS is a mechanism for breaking work (generally related to some specific project) into smaller elements that can be used for assigning resources, budgets, schedules, et cetera. The WBS provides a basis for controlling projects.
Any group of people working toward a common goal as a team. An enterprise will typically have a number of workgroups involved in a product development project.
