CHAOS AND WHY A SYSTEM ENGINEER SHOULD KNOW ABOUT IT

Dr Jan Roodt – StoneToStars Limited, New Zealand
Jan.roodt.nz@gmail.com


1. Introduction

A few articles are planned for this year that will focus on non-linear dynamic systems. Some will focus on complexity and emergence, and I hope that this one will be a readable introduction to the field of Chaos Theory. Expect no more than Chaos ‘lite’ in this first instalment, though. For some this will be old news, and for some I hope that it will bring a greater sensitivity for how our best laid plans and designs may go spectacularly wrong on occasion.


2. The Concept of Chaos

The word ‘chaos’ means different things to different people. My secretary thinks of my office as a place of chaos, a place where it is impossible to find things, a place devoid of order. She sees a randomness in the piles of paper stacked all over the place. There is no obvious principle for the ‘organisation’ of the papers into piles. This is not the type of chaos I want to discuss in this piece.

The concept of chaos that we are interested in system engineering has to do with the temporal behaviour of a system. A system consists of parts that interact. As we know, modern systems have many interdependent parts, including human beings and even the environment. This makes it conceptually and practically difficult to pin down the behaviuor under all operational conditions. We recognize today that there are more nonlinear parts in any interesting system than there are linear elements. It is precisely these nonlinear elements that may cause unexpected behaviour, no matter how well we characterized the system initially. A sudden change in a nonlinear system may give rise to ‘chaos’. According to Hilborn [1], chaos is only one type of behaviour exhibited by nonlinear systems.

The interesting thing about chaotic behaviour is that we can demonstrate it using very simple equations. The only rider is that these equations must be non-linear. Consider the following simple equation, taken from an example in [2]:

This is an iterative (or difference) equation, meaning that for any time-step in the future, we use the previous value of the equation, generated at the previous time-step as the value of the time dependent variable to generate the next value. The equation is nonlinear because it is quadratic in the time dependent term xt2 . Plotting the values on the left hand side against discrete time steps delivers the graph in Figure 1.

Figure 1. This could well be the price of gold over time.

There are a few interesting things we notice. First of all, the graph is erratic, and there is no obvious pattern or cycle. The graph was generated by a deterministic equation, not by some random (stochastic) process. The equation, in one variable, is rather simple – a simple quadratic difference equation. And finally, I calculated this graph in Microsoft Excel, and there was no sampling noise or other noise sources that could influence the shape. The system we described with our equation has very erratic behaviour and it is fully deterministic. Every subsequent value of xt+1is calculated only by using the previous value of xt.

And it is here that we discover another interesting fact about this system. If I use a specific precision to generate the graph, I get a specific shape. If I use a lower precision, the graph starts off the same, and then it starts to deviate after a while, in a very unpredictable manner. It is not just that the difference grows. No, in some areas the graph actually reverts to values very close to that of the high precision version (Figure 2).

Figure 2. The same equation using different calculation precision.

This has grave consequences for us in modelling of a system, and I will come back to this later.

Another interesting property of this type of system was discovered by Edward Lorentz during his work on weather phenomena and weather prediction. Lorentz ran his models on the computers of the time (1963) and sometimes he would stop a model, write down the current values of the system and then restart the model later from that point, using the recorded values. He found even his simplest models for the weather very sensitive to the starting values or the restart values. Remember, in a difference equation, the next function value is only a function of the current value. Melanie Mitchell says that even today our best weather models are only good for about a week into the future, and that it is uncertain if this is as a result of the inherent chaotic nature of the weather systems or if it is just that we lack enough data [3]. My guess is that it is the former.

Let us have a look at what happens if I start our simple equation with a value x0 = 1.001, rather than 1.000. As expected, the new graph is also erratic and moves away from the other two graphs rather early and by the tenth iteration, the difference is visible in Figure 3 below.

Figure 3. A slightly different initial condition causes a different outcome.

It should now be clear that we may demonstrate chaotic behaviour simply by iterating mathematical equations of the type I used here. But what causes chaos in nature? We are not all that sure. What we do know is that we can see chaotic behaviour in chemical reactions and replicate it in the laboratory, for example.

Nicolis and Prigogine [4] gives a very topical example of the variations n global ice forming, as inferred from isotope records of deep sea cores. Not surprisingly the graph of ice volume over the past million years looks similar to the graph of our simple system. Ice forming is probably a function of solar and planetary systems interacting. How all these elements come together is not known, making the current debate on global warming and climate change even more interesting. The short answer seems to be that we know that we do not know enough.


3. Analysing Chaos

As engineers we need to know about a phenomena and hence we have to find ways of working with it to ensure that our real world solutions to problems are safe and sound. If we develop plans for a sky scraper, it is important to understand the physical properties of the materials we will use, and it is critical to understand the systems in which our solution will be embedded, the conditions of the soil, rock structure and the atmosphere, to name a few.

Because we now know that chaos is not equivalent to randomness, analyzing our data can help us understand if there is an orderly or deterministic system driving it or not. If it is deterministic we may be able to discover the laws driving the data, and we may be able to model it for better understanding. As we have seen with the work of Lorentz, sometimes knowing that the state of a system cannot be reliably predicted too far into the future is useful so that we do not expend energy and resources trying to do so, or to design for something that cannot be reliably shown to be a future state of the system.

For this part of the discussion I shall use the standard example of population growth. Consider a population of fruit flies. These flies have a seasonal cycle and the population in one cycle depends on the population in the previous cycle that reached breading maturity. Several factors may inhibit or quicken the population growth. Assume we can throw all these into one “control” parameter a. A typical population prediction difference relationship may look like this:

It is obviously non-linear in the population parameter xt and is known as the logistic equation. Using the Mathematica™ package and some demonstration code [5], the behaviour of the system can be inspected. I use normalized values here to demonstrate the principles, which means that if I set xt = 0.4, then we will be using 40% of the maximum population in the fruit fly world. For an initial environmental control value of a = 0.95, we can see that the population will become extinct after about 50 seasons - Figure 4.

Another way to look at this is to draw the associated phase diagram. In this map we see the parabolic shape of the quadratic population generation curve. On it we draw a line for x0 = 0.4 vertical until it intersects with the parabola. This value is the value of the next population at x1. We now draw a new line horizontally, to where it hits the line corresponding to x1 = xt+1, then a vertical line down to the parabola and then horizontally back to the straight line, which indicates the next value of the population. It can be seen how this zig-zag moves to the origin of the graph after a few iterations - Figure 5. In fact, any value of x0 used with a control value of less than unity, will tend to zero. The series of population numbers is called the orbit or trajectory of the system and it is attracted to zero. From a practical perspective it means that as long as the factors contributing to a result in a < 1, the population will die out.


Figure 4. The population converges to zero – or dies out.

Figure 5. The phase map of a population in decline.

By choosing new values for a and x, a new attractor can be found (Figure 6).

Figure 6. The population stabilises at about 28%

A more interesting result is achieved when we set a = 3.5, x0 = 0.5. Four attractor values appear: 0.87, 0.82, 0.46 and 0.38. This translates into a population of fruit flies at 87% one year, then at 46% another year, etc.

Figure 7. Variable populations appear.

Once a > 3.6 we have a situation where the population is chaotic, as shown in Figure 8. The typical haphazard temporal graph reflects in the chaotic phase diagram. It is very difficult to predict the fruit fly population with certainty several cycles into the future. Any uncertainty in the population will reflect in even bigger error a few cycles down the line, as the behaviour of the system is highly sensitive to the value of the events that drive the control parameter a.

It is realistic to use other approximations for the fruit fly populations in the cases where the control parameter was not driving the system into chaos. However, in the chaotic region, none of the other models would deliver realistic predictions of future populations.

Figure 8. The chaotic region.

The time spectrum does look like noise, and without having prior knowledge, it would take someone with strong imagination to consider this a graph of the chaotic region of the fruit fly eco system. If we were to take a discrete Fourier transform of the data samples, it is possible to construct a power spectrum graph. If the system was truly random (white noise) the power spectrum should be uniform, as all frequencies are present in equal numbers. As a non-linear dynamic system moves into a chaotic region, the power spectrum will show the doubling of the attractors and it will eventually show a spectrum similar to the one below. This is not a sure-fire way to show that a system is chaotic and other techniques may be necessary in conjunction. In future papers we may look into this.

Figure 9. Power spectrum of the chaotic region of the fruit fly system.


4. Modelling Under Chaos Conditions

I mentioned earlier that chaos have some consequences in the field of modelling. Modelling is the art of discovering and identifying regularities in systems and using these to develop simplified artefacts (in software, hardware, etc.) using mathematical constructs that will emulate the observed properties to some degree of realism. In an earlier article in this newsletter [6], l stated that although it is not possible to develop absolute models of complex systems, it is still possible to develop a range of models that will allow the systems engineer to design and deliver real working systems. In the case of systems with chaotic behaviour it is important to realize this early on. Often the irregular temporal evolution of a system is attributed to noisy data, caused by systems outside the system boundaries.

The danger is that engineers will run to find the closest data fitting algorithm and fit the data to a simpler equation. One can see that looking for trends in chaotic data in the classical manner is not the best way to go about things. Similarly using standard statistical analysis will yield answers, but not necessarily the right ones. In the previous section I explained how Fourier analysis may be used very effectively to search for periodicity and “power” in a spectrum.

If it seems that a chaotic system is responsible for your data, the best thing to do is to stand back and to try and devise a difference equation set for your system and to see if it mimics your system responses over short time intervals. It may be possible to develop a set of models for the different regimes of the system, using traditional techniques [7]. In future articles (and if there is interest in this, of course), I shall endeavour to develop and present a workflow framework for this.


5. Concluding Remarks

From this short introduction, it is clear that chaos is a deterministic process, and that it can only arise in non-linear systems. In many cases the behaviour is so erratic that most statistical tests will tell us that we are dealing with a stochastic process.

The systems have some sort of feedback built in. We know this as we used difference (iterating) equations to demonstrate the concepts. The next state of the system is a function of the current state. Chaos is not a result of sampling errors or noise, but we do know that these systems are very sensitive to changes in initial conditions, which makes prediction of long-term behaviour meaningless. At the same time, short term predictions can be very accurate. And to top it all, we cannot discover the history of a chaotic system by looking at the system in its current state – mathematically such a system has equations that are noninvertible.

Engineers must deal with these type of systems in modern design. Often knowing that the system can behave chaotically in a certain regime is good enough to save time and money, by not trying to develop predictive models for the system for long-term interrogation of the behaviour for example. As we learn more about these systems, we will develop better approaches and tools to deal with them. Being sensitive to the fact that they exist, is an important start.

U.S. Department of Defense Releases Systems 2020 Request for Information

The Systems Engineering Directorate is leading the "System 2020" strategic initiative on behalf of the Office of the Director, Defense Research and Engineering to fundamentally change the capabilities for the design, adaptation, and manufacture of defense systems. Recent conflicts have highlighted the need for DoD to be able to field capabilities and systems to respond rapidly to changing threats. The Department is exploring various approaches as alternatives to the typical practice of fielding systems that respond to specific point requirements that were defined years before the system’s initial use. Current requirements-based systems tend to lead to "point solutions" designed to address specific threats, which in turn are assumed to evolve slowly in time. With the pace of events and agility of adversaries, systems of the future need to be far more flexible, adaptable to changing environments, without major redesign, large hardware replacements, or even major software code changes. Systems need to be modifiable or upgradable by reference to virtual models, by plug-replacing subcomponents, or installing new "apps," or upgrading hardware subsystems.

One approach of great interest is the use of engineering methods that enable the development of adaptable systems, supported with tools to enable rapid design changes and rapid fielding. Adaptable systems should be able to counter a broader range of threats and uncertain threat environments than today's defense systems.

To further this approach, the S-2020 initiative is designed to research, develop, and demonstrate engineering tools, technologies, and methods that facilitate the rapid design and manufacture of highly adaptable systems. This initiative is focused on a specific design methodology and a broad class of enabling tools that could make a significant contribution to adaptable system design and development. The design methodology is platform-based engineering (PBE), as defined below, and the entire suite of enabling tools and practices that are intended to foster platform-based engineering are identified as model-based engineering (MBE).

Platform-based engineering (PBE) is a design and development methodology that uses components and subsystems as building blocks in an enduring architectural framework to achieve desired functionalities across a broad range of product lines. The architectural framework provides a common core set of features, and the modular design allows for very rapid adaptation of a system to enable new capabilities and features. Further, subsystems should have utility across a number of product lines.

Model-based engineering (MBE) employs a model-based (vs. paper-based) approach to system design, capturing design choices and details, and executing the development of the system software and hardware. MBE enhances design reuse and speeds the implementation of design changes. Ideally, MBE allows one to integrate the design of electronics, software, physical structure, mechanical systems, connectors, cabling, hydraulics, and all significant components into a virtual realization of a complex system.

Major Systemic Failures - Prevention Approach Needed

A Purdue University researcher is proposing development of a new cross-disciplinary approach for analyzing and preventing systemic failures in complex systems that play a role in calamities ranging from huge power blackouts to the BP Deepwater Horizon disaster and the subprime mortgage crisis.

"The striking similarities in such catastrophes necessitates a broader perspective to better understand such failures," said Venkat Venkatasubramanian, a professor of chemical engineering. "In the history of systemic failures, a few disasters have served as wake-up calls. The Flixborough chemical plant accident in the United Kingdom in 1974, where a Nypro UK plant explosion killed 26 people, was one such call."

Product Description

Solid requirements engineering has become increasingly essential to improved on-time and on-budget delivery of software and systems projects. As more engineering programs make it a mandatory part of their curricula, students and working engineers require significant training to master the field, especially the complicated emerging ancillary software tools vital to the requirements engineering process.

With an intentional focus on software-intensive systems, Requirements Engineering for Software and Systems provides a probing and comprehensive review of the state of technology and developments in intelligent systems, soft computing techniques, and their diverse applications in manufacturing.

Topics covered can be applied to the requirements engineering practices for—

  • Advanced production machines and systems
  • Collaborative and responsive manufacturing systems
  • Digital manufacturing
  • E-manufacturing
  • E-business and virtual enterprises
  • Fit manufacturing
  • Human machine interfaces

Whenever possible, new concepts are first presented from a qualitative perspective to help students gain the insight needed to develop sound designs. Next, a detailed discussion of quantitative tools gives readers the ability to design parameters and configurations for systems they will encounter during their career. And with the use of MATLAB®, students will find out how to apply the latest computer methods to the analysis and design of control systems. Key Features of the Third Edition:

  • Case studies, using the same system progressively, are integrated throughout the text to provide students with a realistic view of each stage of the control system design process.
  • A methodology with clearly defined steps is presented for each type of design problem.
  • Numerous in-chapter examples and skill-assessment exercises, as well as end-of-chapter review questions and problems, including a progressive analysis and design problem that uses the same system, are provided.
  • An introduction to state-space methods of analysis and design is included. These sections are clearly marked and can be taught along with classical methods, taught separately, or skipped without loss of continuity.
  • Tutorials are provided on how to use MATLAB®, the Control System Toolbox, Simulink®, and the Symbolic Math Toolbox to analyze and design control systems. Also included are tutorials on how to use two MATLAB® graphical user interface (GUI) design and analysis tools — the LTI Viewer and the Root Locus Design GUI. All tutorials and MATLAB® code are contained in the text’s appendices so as not to detract from the teaching of control systems engineering principles. References to these appendices are provided at appropriate places in the text.
  • An accompanying CD-ROM provides valuable additional material, such as stand-alone computer applications, electronic files of the text’s computer programs for use with MATLAB®, additional appendices, and solutions to skill-assessment exercises. --This text refers to an out of print or unavailable edition of this title.

Customer Service Incorporates Systems Thinking in 2010

Author: Martin Hofschroer

Jo Causon, chief executive of the Institute of Customer Service, told MyCustomer.com that the current climate showed a "renaissance in customer service" as more companies became more aware of consumer needs. Ms Causon said that developments in customer service were shown by the fact that an increasing number of businesses were integrating their service across departments in their organisation. She told MyCustomer: "There is more of a discussion in the boardroom about how we focus on more of a customer-centric strategy rather than it being a bolt-on or just about the delivery aspect." This approach shows signs of systems thinking as the method is a way of helping people view their organisations not only from a customers' point of view, but from a broader perspective and focusing on the whole organisation as a complete system. Using systems thinking is beneficial to a business because it is a powerful approach to improving service or production, reducing failure and mistakes, and eliminating waste at every level of the organisation.

Engineering Mega-Systems: The Challenge of Systems Engineering in the Information Age

By Renee Stevens
Publisher: Auerbach Publications; 1 edition (July 15, 2010)
ISBN-10: 1420076663
ISBN-13: 978-1420076660

Product Description:

With their ability to cross traditional boundaries and achieve a level of functionality greater than their component elements, mega-systems have helped corporations and government organizations around the world resolve complex challenges that they otherwise couldn’t address with stand-alone systems. Engineering Mega-Systems: The Challenge of Systems Engineering in the Information Age provides a clear understanding of the engineering of this class of systems—a process that demands consideration of increasing program scale and the rapid change of underlying technologies.

Written by Renee Stevens, a Senior Principal Engineer at The MITRE Corporation with decades of experience analyzing, engineering, and acquiring large-scale systems for the U.S. Department of Defense and other government agencies, this book explains how the engineering of mega-systems is inherently different from that of large-scale monolithic systems. It supplies the vocabulary and framework needed to explore the issues relevant to mega-systems. This framework then evolves into the Profiler diagnostic tool that helps you understand the nature and context of the system at hand and, on that basis, select the most appropriate processes, tools, and techniques.

Stevens examines commercial and government applications of mega-systems to provide insight into the contemporary challenges of engineering these systems in three critical dimensions: engineering processes, management processes, and the larger context in which these systems are developed and deployed. Complete with two case studies in engineering mega-systems that illustrate valuable lessons learned and highlight emerging practices, this book supplies the understanding and the tools needed to begin engineering, characterizing, and acquiring mega-systems across multiple dimensions.

10 Useful Ideas on Systems Thinking

By Richard Wilkinson, 2001 – reprinted 11/01/11

“Real life is lived in a complex world system where all the subsystems overlap and affect each other.”

At the heart of systems thinking is the principle of interconnectedness. I compiled the following list to make this core idea translatable to daily life. The ideas presented here are not meant to be the final word on the subject of systems thinking. Indeed, one author listed no less than 28 ideas, a couple of which found their way here, too. This list began in 1995 when the first two entries were shared, appropriately enough, at the conclusion of “The Beer Game”, the famous game developed at MIT to teach systems thinking…..

Panarchitecture: Architecting a Network of Resilient Renewal

by Nick Gall - January 24, 2011

Panarchitecture is a kind of hybrid thinking that combines insights and practices from architectural thinking with those from ecological thinking—specifically the ecological thinking known as panarchy. C.S. “Buzz” Holling coined panarchy as the name of his framework for understanding the dynamics of ecosystems. The pan- in panarchy is meant to connote the Greek god Pan, who is associated with both nature and disruption.

Systems of Systems: Managing Complexity

By General Gaviard

The term “systems of systems” first appears to be an abstruse acronym, but it actually covers a quite simple reality: the networking of several systems, which will thus be able to exchange information and data in real time. The goal: get a more efficient operational synergy.

Regarding the networking itself, the Americans – who have taken the lead in this area – emphasize the word “NCW” (Network Centric Warfare), while NATO chose that of “NEC” (Network Enabling Capabilities). The semantic difference is rather significant, because in the first case the network is seen as a focal point (“Centric”) within the operational system, while in the second it is identified as a support capacity (“Enabling”) to the operations.

Spotlight Webinar: Partnering For Project Success - PM and BA Collaboration

Wednesday, March 9, 2011 at 12 p.m. to 1 p.m. EST Join us for this spotlight webinar delivered by Elizabeth Larson from Watermark Learning. As the importance of both business analysis and project management increases, how can the two best work together? Project managers (PMs) and business analysts (BAs) need to build strong working relationships based on respect and understanding of each other's work. A strong partnership between these two roles can significantly increase the likelihood of project success. To facilitate a shared understanding of the roles, the Project Management Institute (PMI) and International Institute of Business Analysis (IIBA) formed a joint committee to review the content of the PMBOK® Guide, Fourth Edition and the BABOK® Guide Version 2.0, as well as to analyze their touch points. Using these bodies of knowledge as a base, the committee looked at knowledge areas, processes, techniques, and hand-offs between the PM and BA. This webinar quickly reviews how the two bodies of knowledge fit together, highlights areas of potential conflict, and presents strategies for a successful PM/BA partnership.

Learning Objectives:

  • Briefly describe the key areas of work which are described in both the PMBOK® Guide, Fourth Edition and the BABOK® Guide Version 2.0
  • Highlight potential areas of conflict between the BA and PM
  • Discuss effective work strategies for BAs to build a strong partnership with the PM

This webinar is open to all.

DoD Systems Engineering Research Center (SERC)

Mission Statement

The mission of the Systems Engineering Research Center is to enhance and enable the DoD's capability in Systems Engineering for the successful development, integration, testing and sustainability of complex defense systems, services and enterprises.

As a University Affiliated Research Center (UARC), the Systems Engineering Research Center (SERC) was created to conduct systems engineering research for the Department of Defense (DoD) with the intent of enhancing the definition, synthesis, integration and test, deployment, and support of complex DoD systems and enterprises. SERC will act in four specific areas, providing a research-driven engine for meeting DoD’s systems engineering needs:

Community Development

Lead a national community of SE researchers and educators, focused on DoD challenges.

Systems Engineering Research

Identify, evaluate, create and integrate SE methods, processes and tools.

Competency Development

Develop enhanced SE skills and competencies within DoD and industry.

Governance Development

Build a knowledge base to better assess SE effectiveness and to realize improvements.

The SERC's vision in providing these services is based on three concepts:

Collaboration

Until the creation of the SERC, there was no single organization with the reach and depth to tackle the kind of systems engineering research needed in our rapidly changing world. Led by Stevens, the SERC collaborators provide a critical mass of systems engineering researchers – a community of broad experience, deep knowledge, and diverse interests. Our researchers have worked with a wide variety of domains and industries, and so are able to bring views and ideas from beyond the traditional defense industrial base. Establishing such a community of focused SE researchers, while challenging, promises results well beyond what any one university could accomplish.

Innovation

The SERC believes this new community of researchers is an incubator for new and innovative ideas for understanding and improving systems engineering in the DoD space. Innovation is key in finding answers for the critical issues in systems engineering. Some of that innovation will come from cross-discipline research where systems engineering and systems thinking can share ideas with disciplines like biology and sociology where systems are key components. Innovation also includes applying systems thinking concepts to our own research projects and agendas. However, even as we look for new ways, we must integrate the accomplishments and knowledge of the past.

Practicality

Above all, the research undertaken by the SERC must be useful, applicable to real problems, and relevance the key concerns and challenges of today and tomorrow. Systems engineering is a practice-oriented discipline and so we must remain engaged with those on the front lines of systems definition and development. We will conduct research to discover new ways to approach existing and future problems. Guided by DoD’s systems engineering challenges, we see the SERC as an engine for creating solutions that provide ongoing improvement of the defense systems engineering capability through enhanced practices, education, and tools.

Summer Courses at Harvard - Systems Thinking

How we explore the challenges we face is often framed by the approaches and strategies we use to examine them. This course in systems thinking assesses system behaviors by examining the entire system – including human, political, community, resource, environmental, and social processes – to get a holistic view into how organizations and individuals often look at the world, assess problems, and invent solutions. And since the way systems are designed determines outcomes, we also look at the intended and unintended consequences of various actions. Using nonlinear thinking to complement our typical linear way of thinking can lead to deeper insight into problems and potential solutions, which is the focus of this course. (4 credits)

IEEE Standards Association (IEEE-SA)

The IEEE Standards Association (IEEE-SA) is a leading consensus building organization that nurtures, develops and advances global technologies, through IEEE. They bring together a broad range of individuals and organizations from a wide range of technical and geographic points of origin to facilitate standards development and standards related collaboration. With collaborative thought leaders in more than 160 countries, we promote innovation, enable the creation and expansion of international markets and help protect health and public safety. Collectively, our work drives the functionality, capabilities and interoperability of a wide range of products and services that transform the way people live, work and communicate.

The IEEE-SA is governed by the Board of Governors (BOG) who are elected by IEEE-SA Members. The Board of Governors oversees number of committees that are dedicated to manage key operational aspects of the IEEE-SA. The IEEE-SA Standards Board reports directly to the BOG, and oversees the IEEE standards development process. Standards Board members are elected by IEEE-SA members as a privilege of membership, and all Board Members and Committee members must be IEEE-SA members in good standing.

The IEEE-SA standards development process is open to IEEE-SA Members and non-members, alike. However, IEEE-SA Membership enables standards development participants to engage in the standards development process at a deeper and more meaningful level, by providing additional balloting and participation opportunities. IEEE-SA members are the driving force behind the development of standards, providing technical expertise and innovation, driving global participation, and pursuing the ongoing advancement and promotion of new concepts.

System Integrator

A systems integrator is a person or company that specializes in bringing together component subsystems into a whole and ensuring that those subsystems function together, a practice known as System Integration.
Source: http://en.wikipedia.org/wiki/Systems_integrator

Abbreviated as SI, an individual or company that specializes in building complete computer systems by putting together components from different vendors. Unlike software developers, systems integrators typically do not produce any original code. Instead they enable a company to use off-the-shelf hardware and software packages to meet the company's computing needs.
