organization of manufacturing processes on the basis of the
division of labor Æ 8 lines of business
Development of software tools (CAx, PPS)
starting in the 1960s
to support the business processes because of losses of information
Æ problem: no generic solution
Computer Integrated Manufacturing (CIM)
in the 1970s

History – Overview II
Present day developments are aimed at integrating PDM
solutions in product life cycle management systems (PLM)
management and integration of all information of a product
Role of PDM and PLM in the product life cycle
PDM systems communicatively manage engineering data
from earlier product development phases
PLM systems retain engineering data through all the
phases of the product life cycle

Main Functionality of EDM/ PDM
has evolved
from CAD drawing and document management
to life cycle product data management
toward integrated data and process management
aim: integrating all product data and documents and
supporting product development processes end-to-end
provide comprehensive basic functionality for the
management of product data and processes
integrate CAE systems in a common, typically
heterogeneous environment

Plant engineering and plant operation
have been moving into the field of PDM and PLM
application only since the turn of the millennium
due to the nature of manufacturing
every plant made-to-order manufacturers produce is a unique item
and manufactured specifically for a client
due to the plant manufacturer’s products are extremely
complex (an attribute of the product structure)
evolves in the course of the product development process
Æ growing bills of material
growing product structure accompanies a plant up to the phase of
operation as an “as designed”, “as built” and “as maintained” structure

Conclusions - PDM
Abramovici/ Schulte
„While PDM was Information and CommunicationTechnology (ICT) driven and had a narrow focus on the management of product data within product design, PLM has a manage-ment focus addressing all data, processes and applications for the entire lifespan of a product.”
Paul/ Paul
the time for EDM/PDM solutions is not past by any means
a PDM core can play a supporting role in PLM solutions and
therefore deserves to be continuously extended and maintained
this PDM approach could be the basis for developing specially
customized as well as cost effective solutions for small and
