2 What is a digital enterprise? A digital enterprise changes the way people work and how they use information Human/ machine interface Cybersecurity layers Loca=on detec=on technologies Digital Product DefiniHon Customer data capture Mobile technologies Cloud compu=ng Sensors and data gathering Addi=ve and tradi=onal manufacturing

Ongoing industrial challenges Driving product lifecycle data with high fidelity representa=ons Increasing product complexity Difficult to hire new workers

7 The collaboration journey Yesterday Communica=ons oxen in serial fashion Collabora=on meant face-toface communica=on You trusted the data because you trusted the person that generated the data

8 The old communications medium The paper thread

9 What should go into a model-based definition? Implicit and explicit information must be included Historically, drawings contained both implicit and explicit informa=on. Context was important for understanding. However, CAD tools require explicit defini=on of informa=on.

10 Shape definition and visual clarity Many people simply use annotated CAD models as a proxy for a drawing Geometry defini=on Dimensional informa=on Design intent clarity Explicit informa=on

11 But our technology sometimes fails us The digital product defini=on forms the core of how product informa=on is moved through this sociotechnical system. However, s=ll sequen=al Dynamic model re-purposing s=ll lacking MBD must move beyond shape Lifecycle loop s=ll not connected LOTAR Service/MRO Manufacturing Models Analysis Models Needs HW/SW Design Model Physical Alloca=on Model Requirements Func=onal Alloca=on Model

And if this is to become reality Tomorrow

12 And if this is to become reality Tomorrow The 3D digital definihon becomes the conduit in a standards-based communica=on process. The product model is the basis for a secure, authoritahve source of product defini=on. Recycle Service Manufacturing Design You come to trust the process that generates product data (because the person may be unknown).

13 We must have a more complete communication A complete MBD supports lifecycle communication SHAPE BEHAVIOR CONTEXT HUMAN TO HUMAN MACHINE TO HUMAN HUMAN TO MACHINE MACHINE TO MACHINE

14 How is the model structured? Singular representation vs. multiple, connected representations Singular Representa=on Context Behavior Shape OR Mul=ple Connected Representa=ons Shape geometry topology logic constraints For many people, it is a maner of whether they are an author or a consumer. MBD is fundamental to the future of digital manufacturing, but it is more than a proxy for a drawing. Behavior materials process dim./tol. physics Context assembly machining in use re=rement

15 Our representations must match our context The evolution of representations Geometry Behavior CAD based Drawing based Context Lifecycle based Virtual environment based MBx based Specifica=ons Interface requirements System design Behavior Analysis & Trade-off Structure Test plans Requirements ATC Authorize Direct taxiway Pilot Request to proceed Initiate power-up Report Status Initiate Taxi Airplane Power-up Executed cmds Diagram based Document based

16 And we must capture behavioral intentionality Physics-based modeling Through surrogate meta-models create tools that can be used to inform decisions, in real =me, for shop floor use.

22 So where do we start? Adapted from Jennifer Herron, Action Engineering Strategy Establish enterprise strategy Roadmap for slow, steady and accurate Evaluate ExisHng Digital Models Drawing vs. Model-Centric Connected vs. stand-alone Analysis vs. test results Supply chain capacity Build Value ProposiHon: Current state process mapping Future state process mapping to enable reduced cost Technology evalua=ons Evaluate Suppliers Establish an Ecosystem Readiness Determine gaps to implement technologies and data models Execute Methodically Measure against current state Report oxen Business Value OPPORTUNITY LOW Criteria are undefined, out of date, or both MEDIUM Criteria are defined, under change control, and repeatable Maturity & Capability HIGH Criteria are defined, under change control, repeatable, measurable, and con=nuously improving.

23 And how do we get there? Adapted from NSC, Curtis Brown DE Capability Maturity: Technology, Tools, and Standards are being assessed for their business value. DE Readiness Maturity: Data models are being proven for implementa=on in a relevant process environment. DE AdopHon Maturity: Technologies are being deployed in an opera=onal environment. DE AdapHve Maturity: Adop=on of technologies are being scaled and applied to new but similar areas.

This aligns with our college s tag line: How to prepare graduates for jobs that do not exist. The second is a shix in skill requirements.

24 A shift in the focus on jobs A person born today can expect to live to be 100-years old. Their careers will be 60 to 70 years long forcing them to not only change jobs but to change careers. This aligns with our college s tag line: How to prepare graduates for jobs that do not exist. The second is a shix in skill requirements. Demand for skills of the head (cogni=ve), have dominated those of the hands (technical) and to a lesser extent, those of the heart (social) over the past 300 years. In the future, those skills shixs are about to go into reverse.

26 Workforce Education for Industry 4.0 Built upon the old literacies of reading, wri=ng and mathema=cs. New literacies include: Data literacy: read, analyze and apply informa=on Technological literacy: coding and engineering principles Human literacy: humani=es, communica=on and design Higher order mental skills mindsets and ways of thinking about the world. Systems Thinking: the ability to view an enterprise, machine or subject holis=cally, making connec=ons between different func=ons in an integra=ve way. Entrepreneurship: applies the crea=ve mind to the economic and social sphere. Cultural Agility: how to operate dexly in a varied global environment. CriHcal Thinking: the habit of disciplined, ra=onal analysis and judgement.

27 Takeaways Adopt technology to help manage complexity, track cost, and enable decisions. Transforming digital data authoring and consuming processes and prac=ces to achieve a digital enterprise is a culture change. Develop common digital data models, and stop individually clerking data Data architecture and compu=ng infrastructure are key enablers to adop=ng digital enterprise methods and tools. Data packaging and delivery can make or break adop=on. Our representa=ons must match our context. Educa=on of the exis@ng and future workforce is important for achieving technical competence and culture change.
