typically many different kinds of components interacting simultaneously and nonlinearly with each other and their environments on multiple levels - and in the rich diversity of behavior of which they are capable The Springer Series in Understanding Complex Systems series (UCS) promotes new strategies and paradigms for understanding and realizing applications of complex systems research in a wide variety of fields and endeavors UCS is explicitly transdisciplinary It has three main goals: First, to elaborate the concepts, methods and tools of complex systems at all levels of description and in all scientific fields, especially newly emerging areas within the life, social, behavioral, economic, neuro and cognitive sciences (and derivatives thereof); second, to encourage novel applications of these ideas in various fields of engineering and computation such as robotics, nano-technology and informatics; third, to provide a single forum within which commonalities and differences in the workings of complex systems may be discerned, hence leading to deeper insight and understanding UCS will publish monographs, lecture notes and selected edited contributions aimed at communicating new findings to a large multidisciplinary audience Springer Complexity Springer Complexity is an interdisciplinary program publishing the best research and academic-level teaching on both fundamental and applied aspects of complex systems - cutting across all traditional disciplines of the natural and life sciences, engineering, economics, medicine, neuroscience, social and computer science Complex Systems are systems that comprise many interacting parts with the ability to generate a new quality of macroscopic collective behavior the manifestations of which are the spontaneous formation of distinctive temporal, spatial or functional structures Models of such systems can be successfully mapped onto quite diverse “real-life” situations like the climate, the coherent emission of light from lasers, chemical reaction-diffusion systems, biological cellular networks, the dynamics of stock markets and of the internet, earthquake statistics and prediction, freeway traffic, the human brain, or the formation of opinions in social systems, to name just some of the popular applications Although their scope and methodologies overlap somewhat, one can distinguish the following main concepts and tools: self-organization, nonlinear dynamics, synergetics, turbulence, dynamical systems, catastrophes, instabilities, stochastic processes, chaos, graphs and networks, cellular automata, adaptive systems, genetic algorithms and computational intelligence The two major book publication platforms of the Springer Complexity program are the monograph series “Understanding Complex Systems” focusing on the various applications of complexity, and the “Springer Series in Synergetics”, which is devoted to the quantitative theoretical and methodological foundations In addition to the books in these two core series, the program also incorporates individual titles ranging from textbooks to major reference works Hubert Anton Moser Systems Engineering, Systems Thinking, and Learning A Case Study in Space Industry ABC Hubert Anton Moser LuxSpace Sàrl Betzdorf Luxembourg ISSN 1860-0832 ISBN 978-3-319-03894-0 DOI 10.1007/978-3-319-03895-7 ISSN 1860-0840 (electronic) ISBN 978-3-319-03895-7 (eBook) Springer Cham Heidelberg New York Dordrecht London Library of Congress Control Number: 2013955727 c Springer International Publishing Switzerland 2014  This work is subject to copyright All rights are reserved by the Publisher, whether the whole or part of the material is concerned, specifically the rights of translation, reprinting, reuse of illustrations, recitation, broadcasting, reproduction on microfilms or in any other physical way, and transmission or information storage and retrieval, electronic adaptation, computer software, or by similar or dissimilar methodology now known or hereafter developed Exempted from this legal reservation are brief excerpts in connection with reviews or scholarly analysis or material supplied specifically for the purpose of being entered and executed on a computer system, for exclusive use by the purchaser of the work Duplication of this publication or parts thereof is permitted only under the provisions of the Copyright Law of the Publisher’s location, in its current version, and permission for use must always be obtained from Springer Permissions for use may be obtained through RightsLink at the Copyright Clearance Center Violations are liable to prosecution under the respective Copyright Law The use of general descriptive names, registered names, trademarks, service marks, etc in this publication does not imply, even in the absence of a specific statement, that such names are exempt from the relevant protective laws and regulations and therefore free for general use While the advice and information in this book are believed to be true and accurate at the date of publication, neither the authors nor the editors nor the publisher can accept any legal responsibility for any errors or omissions that may be made The publisher makes no warranty, express or implied, with respect to the material contained herein Printed on acid-free paper Springer is part of Springer Science+Business Media (www.springer.com) Foreword Nowadays system development is multi-disciplinary Disciplinary knowledge, perspectives and thinking no longer suffice to develop systems in an efficient and effective way Development team members need to consider the system as a whole and work together closely across disciplinary boundaries, and systems engineers are required that know enough of the disciplines involved to ensure the total quality of the system Although the concepts of systems engineering and systems thinking have been around for several decades, an understanding of how developers actually work together across disciplinary boundaries and how they learn from each other, is still lacking What does it mean to think in terms of systems in the context of a highly integrated system in which partial, disciplinary solutions affect each other? How developers learn from each other in such a multi-disciplinary environment, i.e., how does systems thinking evolve? And most importantly, how can we improve this process: How can systems thinking be learned more effectively and efficiently given the fact that our education is essentially disciplinary? These questions are addressed in this book in a unique way as part of a PhD project executed within space systems industry To understand systems thinking, methods from educational and social sciences were used in an engineering context, multiple real development projects in industry were analyzed, and the analysis covered an extended period of time A multi-level analytical framework was developed, based on activity theory, allowing a detailed analysis of multidisciplinary interaction over time Short and long term mechanisms essential for learning to think in systems were identified, and finally, a strategy called WAVES (Work Activity for a Versatile Evolution of Systems engineering and thinking) was developed to improve the evolution of systems thinking This book is an excellent resource for researchers and practitioners interested in systems thinking and in solutions to support its evolution It not only provides an extensive overview of the developments in this field, but provides a unique and rich account of the practice of interaction between disciplines and learning across disciplinary boundaries Of particular interest for researchers is the developed analytical framework, which is applicable for the analysis of a wide variety of work activities in the context of engineering design and beyond Of particular interest for industry is the proposed human resource development strategy, WAVES, to improve the development process by improving the effectiveness of interaction between disciplines, the speed of systems thinking development, and the quality of boundary management When Hubert contacted me with his idea for a research project, we could not have anticipated the richness of the project and the results Not only did the VI Foreword research deal with multidisciplinarity in an engineering context, it was multidisciplinary in its own right, involving concepts, methods and strategies from yet other, non-engineering disciplines The dedicated involvement of LuxSpace and my colleague Gudrun Ziegler have been essential in achieving the depth and quality the topic requires Most of all, however, Hubert has to be credited with actually crossing boundaries, venturing into unfamiliar disciplines, bringing everything together, and providing the reader with a unique account of systems thinking and a solution for its improvement 20 October 2013

and Outlook smallest scale contradictions Doubts in extra-disciplinary decisions are medium scale, and conflicts between different work standards and approaches are largescale contradictions The quality of the multi-disciplinary interaction is an essential factor influencing the practice of systems engineering and its evolution It is influenced by factors such as awareness of interactors' diversity and orientation towards extra-disciplinary interactors, differences in interactional responsiveness, and selection of interactional techniques Observed interactional techniques are referring to experience in remarks and narratives, physics basics, analogies and natural language The diversity of individual reference repertoires is an indirect measure of the level of systems thinking As learning in general, the evolution of systems thinking is regarded as change of knowledge This change is a vertical development within disciplines (fieldrelated and lifecycle-related disciplines) from immaturity to maturity (climbing the ladder of performance) Furthermore, it is a horizontal development, i.e beyond disciplinary boundaries (jumping from ladder to ladder) The horizontal development contains also relationships between the disciplines (platforms between ladders) The evolution of systems thinking, i.e learning of systems thinking, can be described as crisscross climbing in a scaffolding of ladders and platforms Change of factual, conceptual, and relational knowledge has been identified to occur within minutes, days, and years Change of procedural knowledge has been identified within days and years The short-term change can be identified as sudden insight within multi-disciplinary discussion The long-term change contains two types of continuous change The first type is a gradual movement from the periphery to the centre of extra-and intra-disciplinary fields of practice The second type is a cyclic process of activity systems, which starts with questioning current practices such as the work approach of engineering teams This second type of change is expansive learning How can the evolution of systems thinking in practice be improved? The answer to this second part of the main research question is: by tackling the factors, which influence the evolution of systems thinking This is the basis for the objectives of the developed support This support, the WAVES (Work Activity for a Versatile Evolution of Systems engineering and thinking) strategy, comprises two paths The first path, WAVES-intro focuses on the introduction of newcomers These are newcomers into professional life, to (space) industry, in a company, in a team, and newcomers to performing a task The second path, WAVES-conti, addresses the continuous development of systems thinking in practice It stresses the quality of multi-disciplinary interaction and discussion A combined implementation and evaluation approach was developed This approach is a step-wise implementation in iteration with the evaluation It starts within the S1 team of Company L before it is extended to entire Company L Afterwards it is planned to implement WAVES within systems engineering departments of two large organisations According to this approach, WAVES has been initially implemented in Company L The initial evaluation has shown positive results of the implemented instruments of the WAVES strategy 9.2 Contributions 9.2 313 Contributions The contributions of this research project are classified intro three different categories: contributions to research (see Section 9.2.1), contributions to engineering education (see Section 9.2.2), and contributions to industry (see Section 9.2.3) 9.2.1 Contributions to Research The two scientific objectives of the research project were: • • an improved understanding of learning in engineering teams who are developing (space) systems, and an improved understanding of systems thinking learning in practice The results of the research project contribute to an improved understanding of learning in high-technology environments This includes detailed insights into processes, which are often described as 'return of experience' and 'learning by experience.' The results provide insights into human activity where technology is used to design, develop, manufacture, test, and operate new technology as well as the change of this activity Findings from other research performed with grounded theory, phenomenology, and (experimental) work psychology are supported and stressed by the results In addition, this research project contributed to learning research in engineering by introducing an analysis framework based on activity theory This framework allows for studying human activity with and on technology on different temporal and organisational levels It has been shown that activity theory can be used to describe not only the man machine interaction but also the interaction of man creating machines Finally, this research project contributed to bridging the gap between latest social science research and engineering research by extending and crossing disciplinary boundaries 9.2.2 Contributions to Engineering Education The importance of multi-disciplinary interaction for the evolution of systems thinking has been identified The comparison of the four empirical studies showed that interactional techniques and multi-disciplinary quality of interaction are relevant for projects within industry as well as for student projects The diversity and size of the reference repertoire can be already increased in university Therefore, project work in multi-disciplinary teams is of high value for the individual students and future employees in industry This study shows benefits of participating in multi-disciplinary student projects such as working on educational satellites, cubesats, racing cars, robots, and rockets 314 9.2.3 Summary of Main Results, Contributions, and Outlook Contributions to Industry The practical objective of the research project was motivated by the question of how to best introduce newcomers into a small company This motivated the first objective of fostering learning of systems thinking in practice, which goes beyond the issue of optimum introduction of newcomers into a small company Based on the results of the empirical studies, the WAVES strategy has been developed, implemented, and partially evaluated Until now, these interventions are implemented in Company L and the implementation in Company D is foreseen WAVES has been developed as generic as possible to allow for its implementation in other companies and industries Although the major focus of WAVES is on fostering the learning of systems thinking, its application improves also the way of working, i.e the systems engineering approach 9.3 Outlook The research project has answered the research question and contributed to an improved understanding of the work activity within systems engineering teams in space industry From these insights, other interesting paths of continuation and open issues remain to be solved in future As this research project focuses on space industry and a limited number of cases, additional empirical studies should be performed to further analyse the evolution of systems thinking and learning in engineering practice The collected data allows for analyses with different research foci, e.g a quantitative analysis of the office records within S1 Coding by additional researchers would improve an analysis that focuses on quantitative aspects The rich data on interactions, allows for further investigation into critical interaction instances and into the use and role of interactional devices in work practice The link between critical interaction instances and extra-disciplinary questioning can be analysed in more detail The concept and definition of the multi-disciplinary quality of interaction can be reviewed, developed, and extended Reasons for the differences in preferred and required interactional responsiveness are an issue that should be studied in detail Such a study requires other research designs, e.g a survey of observations in different organisations and industries Another research strategy, such as longterm shadowing of multi-disciplinary teams and individuals would complement the results of this research project The implementation, evaluation, and refinement of the WAVES strategy should be continued within Company L The comprehensive evaluation of WAVES is a future project, which is of vital importance for following implementations Combined with this evaluation, WAVES should be implemented in other companies in the same sector and in other industry sectors Appendix A Overview of Data Collection Methods A A Overview of Data Co llection Methods Overview of Data Co llection Methods Research Journal A research journal is an ongoing chronologic document written by the researcher and containing different types of information Research journals, as other journals, reflect the perspective of the writer and cited perspectives of other informants It contains information, which complements data from project journals, descriptions of research setup, methods, and strategies as well as reflections of the researcher on the research project Research journals require a rather small effort from the researcher as they mainly serve as complementary data source and medium for reflections on the research project The categorisation and analysis of research journals is expected to require the largest effort for the researcher although this depends on the design, i.e if the journal is kept formally with a template and possibly in electronic form, or if it is in informal style written into a textbook Project Journals Similar to the research journal project journals are ongoing chronologic documents written by the researcher They contain project-specific information, i.e technical details of the system of the project and observations of the (participant) observer The observation information comprises field notes from the observations in different situations, such as desk, coffee corner, during lunch, and in meetings, and pointers to other data sources such as audio and video records, setups of audio and video recordings Technical details are related to the participant observers role in the corresponding project The researcher effort is a bit less than for the research journal as the journal is by definition focused on a single project Participant Journals Participant journals are project journals kept by participants Depending on the instructions, these journals can have a stringent template and formal character or completely free form providing the largest freedom for the writer Participant journals require a large effort of the participants This effort is comparable with 316 A Overview of Data Collection Methods the researcher effort for writing the research journals This data collection method requires the participants to document what they are doing and represents the exclusive perspective of the journal writer The researcher effort depends on the allowed freedom of the writers but can be generally compared to the other two aforementioned types of journals Audio and Video Records Audio and video records of observed activities are the least pre-filtered data collection method The data can be approached and revisited with different perspectives What is captured by the recorders can be observed with different foci several times as the main restriction on the data is viewpoint The viewpoint can be a stationary camera, which is not moved or refocused on pre-defined field of view, or it is a mobile camera that is switched on when the observer identifies something interesting during the observation This option causes already a preselection which might constrain the value of the data afterwards or ease the selection of critical situations as the observer's attention has been caught by something happening Audio and video records can be performed in regular formal and informal meetings, within offices of participants, and in the coffee corner to get insights into diverse work situations For a participant observer regular records represent the viewpoint of one member in a team, i.e only meetings are recorded in which the participant observer is involved The regular office records are made in the participant observer's office therefore show the interaction of the participant observer and the other participants located in the same office Writing the minutes of meeting and memos as a service in return increases the acceptance of the recording devices, which are quickly not noticed anymore by the participants in interaction Apart from acceptance, audio and video records require no participant effort Researcher effort is firstly to set access and permission to record Secondly, the records have to be listened/watched at least two times before selection and more in depth analysis Transcription of selected excerpts requires significant efforts Email Collection Collected emails provide insights into written interaction between co-located and distributed actors In addition to the email attachments such as pictures or other documents under discussion are accessible Only emails, from and addressed to (direct, cc, bcc) the participant observer in his role as thermo-mechanical specialist within the teams are stored Email collection does not require additional efforts for the participants and provides an authentic insight into written interaction between participants With common email exchange tools, which are implemented in standard office, software packages the search and tracking of email interaction can be performed with a small researcher effort A Overview of Data Collection Methods 317 Documentation Collection Documentation provides insight into formal documents such as technical drawings, minutes of meetings, requirements specifications, and statement of work These documents represent what is "frozen into documents" (Ehrlenspiel, 2007) In addition, informal documentation such as hand sketches written on napkins, paper, or whiteboards complement the set of information Documentation collection does not require an additional effort for the participants as the document creation is part of the observed work activity Documentation collection requires a higher researcher effort than email collection as the storage structure is mostly less organised and therefore a higher search and structuring approach is necessary Interviews Interviews require a small participant effort, as participants have to spend time to answer questions from the researcher Researcher effort depends on the structure of the interview A non-structured interview requires the highest analysis effort for the researcher but leaves the most freedom for the interviewee Physical Artefacts Physical artefacts such as prototypes, test models, and final products provide information on what and how has been realised in the end This information allows for analysing decided solutions and their implementation There is no participant effort and the researcher effort is small, mainly the documentation (e.g pictures) and its accurate localization in time Appendix B B Co mple mentary I nfor matio n o n S1 Complementary
