Co-operative engineering• The synchronized engineering of one and the same part of the product by different experts

It requires a virtual product model that allows different data views of one and the same part of the product and moreover needs functionalities for data management, such as transformation consistency checking, monitoring, control and modifications of the different engineers, to guarantee a conflict-free synchronized design and manufacture.


Collaborative engineeringthe collaborative engineering of physically distributed teams working on one and the same product as if working at a round table, which is made possible by an IT infrastructure.


Simultaneous engineeringat any time of the design process each product life state is taken into consideration, applying the appropriate concerned expert knowledge by means of forecasting, prognosis and simulation.


Electronic commerce• Building construction products are assembled by other products, which are supplied by other players on the global market place. These are usually not one-of-a-kind products, i.e. they are mass-production articles.

• An initially chosen product can easily be replaced by another similar product or another supplier can deliver the same product.

• Customers and suppliers should be brought together in very early phases in order to optimise their businesses.

Workflow vs. Engineering Workflow vs. Engineering WorkflowWorkflow

Applying Workflow systems for Concurrent Engineering requires additional functionalities:

Organisational structures which are project specific Allow ad hoc workflows and workflow

modifications embedded mechanisms for revisions, notification

and versions embed classical project management software

Many SMEs hesitate to introduce complex IT environments into their everyday work

Software houses and internet providers start to offer web-based thin-client services.

Data management (installation, backup, recovery, maintenance) is done on the provider side.

ChallengesChallenges

Validate product and process models against existing applications and legacy data

compare and integrate A/E/C process models with generic product & process models from other domains, e.g.– WfMC / SWAP (Workflow)– aecXML– CORBA

Proposal for EAPPM initiativeProposal for EAPPM initiative Building a European Knowlegde Base with sample data

from real projects in all relevant aspects– CAD files

– cost calculations and cost data

– data of project management software

– data of specialized fields (geotechnics, earthquake, ...)

Allows researchers and software developers to – validate their models and

– define standardized benchmarks and conformance tests for PPM based software
