  1. Last decades evolution from local to collective IT IT innovation in collective data flow Change in engineering new metaphors Large engineering practices concurrent engineering Collaborative large engineering from IT dream to reality

  2. 70th culture: mass production man = weak point IT = opportunity to remove people from operational work End 70th 1st CAD stand alone  work mechanization ROI at least 5 jobs inside the design or downstream chain. Typical CAD market : wiring, electronics, drawing“nice” successes, removing a lot of people from the working line, and interesting failures Mid 80th CADCAM support  machine for itself. man activity no longer the key subject. Typical CAD market: :mechanical design CAD data exchange between different CAD systems, CAD data to CAM and to NC data, to fix bugs into CAD systems; migration support Last decades IT evolution1_ the road to designer work mechanization Automatic control & scientific IT Dissemination of emerging CAD stationn BUs 10-20 designers Central CADCAMsupport team mgt4 BUs 100 ++ designers

  3. Detailed drawing files and plans 100% CAD-CAM (1990) research of representations adapted to engineering data IT processing. features to improve CAD-CAM link increased automation 3D solid to model assemblies  DMU & collective work DMU as a CAD tool to replace physical mock-ups & to share product visionillustration : AIT automotive and aerospace EU project (95) DMU modelling and methodology, 3D heterogeneous exchange 3D visualisation for project reviews. Drawback: 3D CAD models limited in size, and parametric not easy to exchange. DMU as a PDM tool to be backbone of collective work illustration ENHANCE aircraft EU project, (98) common models for data, milestones, review meeting, exchanges …heterogeneous data safe and fluid non collocated environments. DMU configured set of 3D parts, + other technical objects as drawings, documents,etc. to build a common product model. Last decades IT evolution2_ the road to concurrent engineering

  6. Leading vision = collective data production, not individual drawings or schemas  data flow data exchange between people and IT machines, and  data produced from other data, by people knowledge and software tools. New disciplinesCAD mutation analogy last centuries mechanization. production system management; resources/process logistic and supportScattered handicraft resources expensive industrial machines + large teams, horizontal or vertical integration + standard machines machine prices decrease organisations kept, integration goes on. : Rational methods needed for industrial IT objects or machines. often a more “natural world” turn out to be a more abstract and rational one to set-up efficient IT collaborative environmentcolour, 3D visualisation, parametric codification, methods handbook, … virtual meetings  meeting categorization, QoS, security, rendezvous management.

  16. Changes in work spaceillustration IT innovationillustration individual A0 size drawings boards « an arm size, motion and memorization », A4/A3 reduced vision and motion Zoom,multi-layers, tree-file; 3D access but increased degree of abstract as space being replaced by time+logic No more quick look at drawings pinned to boards, tocatch evolution publish and subscribe ; interface information patterns (features);tracedcollaborative sessions No more global vision of design office & people walking around can't provide unexpected useful feedbackNo more physical document cabinets design review DMU + PDM . Multimedia annotation mechanism Semantic navigators (XML and ontologies)Yellow pages, knowledge repository lost of confidence and complicity as digital information can be send away and judged by unknown people abstract document fluent management & ownership mechanisms supporting and ruling day to day worksafe networks Changes in engineering environment 1_ the zero paper metaphor[decision support]

  17. Before : sequential mature information, signature= responsibility signature mechanism : author/skill project_boss/product, office_boss/enterprisedocument administrator in charge of import or export of validated data; engineering models organised for next step process Now: parallel immature information, ownership dynamic transferdown stream actor expects early upper “finished work” upstream actor expects early experiment (real, virtual) feedback data administrator in charge of rule and ownership administration etc.engineering (multi) models organised for interaction Changes in engineering environment 2_ The break the wall metaphor[action] Immature data sharing Mature data transfer

  18. data hub with impersonal engineering put and get data . breaking the wall concept  every one under pressure in an information loopIT data and IT machines accelerate drastically data change and data transfer speed man in the loop boss manages data indicators and data administrator control data speed. counterweight : human factors + network model man “at the nodes” + IT assistance model of large and shared engineering between partners, withmanagement of product/process frontiers and contractualresponsibilities.
