2What is Engineering? The profession in which a knowledge of the mathematical and natural sciences gained by study,experience, and practice is applied with judgment todevelop ways to utilize, economically, the materials andforces of nature for the benefit of mankind.Engineering is a profession like medicine, law, etc. thataspires to high standards of conduct and recognizes itsresponsibility to the general public.
3What is an engineer?Engineers use their imagination and analytical skills to invent, design, and build things that matter.They are team players with independent minds who ask, “How can we develop a better recycling system to protect the environment, design a school that can withstand an earthquake, or create cutting-edge special effects for the movies?”By dreaming up creative and practical solutions, engineers are changing the world all the time.
4Science, Engineering, and Technology Scientist - Like an engineer, but a primary goal is the expansion of knowledge and understanding physical processes.Engineer - Applies knowledge of math and the physical sciences to the efficient design and construction of usable devices, structures and processes.Technologist - Technologists focus on direct application of established engineering principles and processes. Math, the physical sciences, and underlying engineering theory receive limited coverage. More interested in hardware and processes.Technician - Completes a 2-year degree in a narrow technical area such as electronics, drafting, or machining.Artisans - Training may be a combination of schooling and work experience. Examples include, welders, machinists, electricians, carpenters, painters, steel workers, and artists.

7Employers and Career Paths for Engineers Industry, Self, Education, NGO, Govt., Military, OthersCareer Paths:1) Corporate ladder2) Independent entrepreneur3) Military or government4) Engineering and social service aboard5) Professor/engineer6) Graduate work outside engineering7) A mix of aboveIndustry, Self. Education, Non-profit, Fed. Govt., Military, Other Govt. Others
8Engineering as a Profession Engineering possesses those attributes that typicallycharacterize a profession:Satisfies an indispensable and beneficial need.Requires the exercise of discretion and judgment and is not subject to standardization.Involves activities that require knowledge and skill not commonly possessed by the general public.Has group consciousness for the promotion of knowledge and professional ideas and for rendering social services.Has a legal status and requires well-formulated standards of admission.
9Systems EngineeringAn interdisciplinary field of engineering focused on how complex engineering projects should be designed and managed.Issues such as logistics, the coordination of different teams, and automatic control of machinery become more difficult when dealing with large, complex projects.Systems engineering deals with work-processes and tools to handle such projects, and it overlaps with both technical and human-centered disciplines such as control engineering, industrial engineering, organizational studies, and project management.

12What we do mean by Global Problematique? The interconnected and interacting issues of all types which affect the becomingof life in the global ecosystemThe uncontrollable and interacting circumstances of all types, which constrainthe timely and effective resolution of these issues.The Club of Rome introduced the phrase “World Problematique” in 1960s. It has beenused by many persons who deal with the set of issues combining into a threat to ourcommon future. It is the entire framework of life on Earth and its contents as such:(1) What we, humans, traditionally call Nature, or the environment, considered aseverything alive or not (air, land water and minerals), and see commonly as external tohuman society.(2) Contrary to the most common attitude, the global ecosystem includes our species.Homo sapiens is not external to its natural context but definitely inside of it and utterlydepends on it for its existence. We are now the form of life that impacts most severely onthe rest of the ecosystem. It is therefore logically incorrect, when addressing theproblematique, mentally to isolate our species from its natural context.
13Is World Sustainable? The Club of Rome Brundtland Report UNEP MDG One Planet Many PeopleRole of EngineeringRole of Systems EngineeringA New Path for World Development
14New Challenges for Engineering Complexity…through adopting a systems approachUncertainty…when decision-making in the absence of complete information;Change…by challenging orthodoxy and envisioning the future;People…through consultation processes and negotiation to meet society’s and individual’s needs;Limits to growth…through seeking efficient resource use, ensuring pollution control and maintaining ecosystem services;Whole-life costs…by considering environmental and social externalities and embracing life-cycle management;Tradeoffs…by providing optimization around a single variable to create solutions acceptable for all; andNew leadership…through building multidisciplinary / multiculture teams like symphonies.
15Systems WorldThe world around us can be looked at in a variety of ways. One way is to see the world as made up from many interacting systems: weather, societal, economic, ecological, floral, faun-al, tectonic plate, oceanic, and so on. This is very much a connected view of the world: nothing is isolated and totally independent; everything is part of something bigger, and everything comprises many interacting parts – subsystems.
16Global Crisis Crisis = Threat + Opportunity 危脅 : Threat Global Community機會 : Opportunity EngineeringCrisis = Threat + OpportunityGlobal CrisisCrisis (危機) =危脅+機會危脅 : Threat to Global Community機會 : Opportunity for Systems EngineeringCrisis = Threat + Opportunity
18Global IssuesThe present path of world development is generating imbalances, vulnerabilities, inequities, exclusion and polarization which constitute clear threats to the prospects of both present and future generations. The Program draws on the independent, multicultural and interdisciplinary membership of the Club to clarify the key elements of a new path for world development. It will propose new lines of thinking and action which are urgently needed to: avert the risks and consequences of catastrophic climate change; reduce the devastating impacts of human activities on ecosystems and environment and the overuse of the biological and physical resources of the planet; achieve more fairness in the distribution of vital resources and opportunities and of the costs and benefits of globalization;Avert=
19Global Issues - contAccelerate global efforts to eradicate poverty and deprivation of a growing world population; Adapt and reform the structure of international institutions to address the integrated problems of a world in rapid transformation; and broadly, to achieve equitable and sustainable world development and thus preserve international security and world peace. In order to manage the complexity of such an extensive “problematique”, the program strategy focuses successively on five clusters of interconnected issues while recognizing the linkages between the clusters. In each case, a small expert conference develops proposals for action and identifies issues for in-depth analysis through internet-based, international research networks. The five clusters are:
20The Five Clusters1. Environment and Resources: Climate Change, Energy Security, Ecosystems and Water.2. Globalization: Distribution of Wealth and Income, Employment, Economic Restructuring, Trade and Finance.3. International Development: Demographic Growth, Environmental Stress, Poverty, Food Production,4. Social Transformation: Health and Employment, Social Change, Values, Culture, Identity and Behavior.5. Peace and Security: Justice, Democracy, Governance, Solidarity, Security and Peace.
21Reminding PointsSystems engineering denotes different things to different peopleSocial & Human factors are critical to the birth of visionary systems engineering and engineersSystems engineering and engineers are critical to mission and programmatic successContinuously Improving systems engineering capability is a challenging and important task for the Military services, Government agencies, and Industries
22Systems Engineering on Global Citizenship Systems Engineering fosters key interdisciplinary research and development on corporate citizenship and provides a framework for further academic debate on corporate responsibility in a global society.This provides a unique forum to discuss the consequences of the social and political mandate of business firms and examines the implications of these consequences for the theory of the firm.Systems Engineering should collaborate with various disciplines such as management studies, economics, sociology, legal studies and political science to evaluate the concept of corporate citizenship and to analyze the role of private business in global governance and the production of global goods.

24The ConductorThe most important person in an orchestra is conductor. He, or she does not play an instrument at all. The conductor's job, at its most basic level, is to indicate the beat of the music. Most conductors use a long stick, called a baton, to make the beat as clear as possible.The conductor moves the baton towards several imaginary 'points' which indicate which beat in the bar the orchestra is currentlyplaying.The conductor is also responsible for the preparation and rehearsal of the orchestra, and for making interpretative decisions - such as whether a certain passage should be slow, fast, soft, loud, smooth, aggressive, and so on. A conductor communicates these decisions both verbally (in rehearsal) and during the performance usingdifferent movements, gestures, and facial expressions.
25Interdisciplinary Engineering Fields Are you an artist, musician, or athlete? Wouldn’t it be great tobe able to combine your talent and passion with a career? There are plenty of traditional, nontraditional, andinterdisciplinary fields of engineering. They might just matchup with your interests, whether they involve design,architecture, law, business, geography, psychology, oreducation.As an acoustical engineer, you might develop a state-of-theart sound studio, or as a sports engineer you might createequipment that tests the performance of athletes. You might also work in “human factors engineering,” afascinating field that takes human behavior and psychologyinto account in developing products and systems.
26Systems Engineering: an Art and a Science We can compare systems engineering to an orchestraand its ability to perform a symphony. Most peopleunderstand what music is, but not everyone can play aninstrument. Each instrument requires a different level ofexpertise and skill. Some musicians spend their entire careersmastering a single instrument, which is good because eachone needs to be played well. But sophisticated music involvesmany different instruments played in unison. Depending onhow well they come together, they may produce beautifulmusic or a terrible cacophony.
27A Symphony is a SystemMusicians practice the science of music, and follow the process of translating notes on a page to play their instruments. The maestro, lead them to connect the process of playing to the art of creating great music. Maestros do a lot more than just keep time. They: • are born with the insight into musical instruments and musicians beyond pitch, rhythm, dynamics, etc. • are necessary when the orchestra reaches a certain size and complexity • have typically mastered one or more musical instruments • may be composers • select and shape the music that an orchestra plays • interpret a composer’s music in light of the audience • strive to maintain the integrity of the composer’s intentions • organize and lead the musicians • are responsible for the success of the performance
28Maestros and Systems Engineers They know what the music should sound like (the look and function of a design), and lead a team in achieving the desired sound (the system requirements). Systems engineers know the fundamentals of mathematics, physics, and other pertinent sciences, as well as the capabilities of various people and disciplines: • master a technical discipline and practice multiple disciplines • understand the end game and overall objectives of the endeavor • create a vision and approach for attaining the objectives • are architects or designers • select / shape the technical issues to be addressed by multidisciplinary teams • interpret / communicate objectives, requirements, system architecture, and design • responsible for the design’s technical integrity • organize / lead multicultural/multidisciplinary teams • responsible for the successful delivery of a complex product or service The similarities between maestros and systems engineers describe the latter’s desired behavioral characteristics and capabilities.end game=[éndɡèim] [명사] (체스·경기의) 최종회, 막판; ((일반적으로)) 최종 단계; [군사] 엔드 게임 ((적의 탄도 미사일 방어 시스템을 기만하는 수단의 일종))
29Test like you fly, fly like you test ! Systems Engineers pay particular attention to verification and validationVerification answers the question: “Did we build our system right?” If yes, it proves our product meets the requirements. Practice the hard-earned lesson, Validation answers the question: “Did we build the right system?” If yes, it is supposed to do, which often goes well beyond just meeting requirements.Test like you fly, fly like you test !
30Global EcosystemThe global ecosystem is the entire framework of life on Earth and itscontents.First, it contains what we, humans, traditionally call Nature, orthe environment, considered as everything alive or not(air, land water and minerals), and see commonly as external tohuman society.Second, and contrary to the most common attitude, the global ecosystemincludes our species: Homo sapiens is not external to its natural context,but definitely inside of it and utterly depends on it for its existence. Weare now the form of life that impacts most severely on the rest of theecosystem. It is therefore logically incorrect, when addressing theglobal problematique, mentally to isolate our species from itsnatural context.
