Who is allowed to make changes? Who has the right to make a copy? What are the rules for verifying digital data? Which version did we send to our customers three weeks ago? How can I prove to the client that this or that version is correct? These problems are difficult for the head of the design bureau to deal with, and they are often exacerbated if a large number of employees are distributed on different sites or even external suppliers united in a development and production environment. PDM or PLM? The acronym PDM (Product Data Management), which stands for Product Data Management, is commonly used to mean technical data and process management. In marketing documents, this is sometimes confused with PLM (Product Lifecycle Management), which refers to product life cycle management.
Effective data management is a strategic method aimed at providing optimal support throughout the product life cycle, from the initial idea of the product to its decommissioning at the end of its service life. Therefore, it is a more comprehensive method with broader goals, while PDM can be considered as a central element of the PLM strategy. There are currently various PDM systems on the market. They have been developed in accordance with three different principles. Some of them are initially document management systems and meet the technical requirements for design-based enhancements. Others approached product development in terms of enterprise resource management (ERP) with the goal of managing product development data in commercial software with additional modules. adapted.
However, the most comprehensive data integration systems are rooted in the development world. They are fully tailored to the needs of product development, specific aspects of product data, and the processes used in development services. The managers of the design bureau are familiar with this type of system. They find the best answer to their needs and can maximize the use of system-specific properties, their capabilities and graphic data. These solutions have powerful integration capabilities, are very easy to use, and offer the most powerful benefits for product developers. Articles An article or part may represent a physical or virtual component, set, subset, or complete product. This can be a manufactured or purchased part, and each part is identified by a unique name or number.
The main information associated with the article (article number, title, version number) is stored in the article repository. To display complex article structures, the main article data is simply metadata that relates to other documents, files, and information. Documents Documents contain information related to the content, which may describe other objects or be autonomous. Typical documents in the PDM system are, for example, models and plans, calculations and data integration, as well as texts such as specifications or descriptions. The ability of the PDM system, like any standard data management system, to manage office documents is of great interest for engineering-oriented operations, as it provides access to any administrative document. sale, production or development through a single standardized interface. However, when developing a product, PDM systems must manage documents with much more complex requirements in terms of format, structure, version history, change management and processes. Requirements that go far beyond, for example, commercial letters or personal information.
Projects The PDM system uses the data integration object to collect goods, kits, parts, and documents for a sales order or development project. In this case, the PDM system does not act as a complete project management system, but provides an overview of all relevant data associated with the entire project. Articles or documents can be assigned to several projects without duplication, which simplifies editing: a copy change will be automatically applied to all projects containing the document. One of the great advantages of project-oriented management is that all information related to the project is related.
“Knowledge is the binding of information”, which means that all related pieces of information can be obtained from one place, which eliminates the need for redundant storage. Through the use of a systematic ranking method and well-defined processes, product data management systems provide a high level of organization and reliability necessary to maintain competitiveness in the current product development environment. The PDM system manages related data as objects. These objects are, for example, articles (or parts), documents and projects.
