Paradox: Holarchical view of system of systems engineering management
No full textThis paper focuses on a method of developing a framework for effective System of Systems Engineering (SoSE) management.While developing the management process in dealing with SoSE, we are searching for ways to engineer multiple integrated complex systems, which can be concurrently, highly emergent and effectively governable. The authors propose to utilize the "holarchical view" methodology to identify and examine this essential phenomenon of paradoxes of SoSE management. The proposed method is based on the Boardman-Sauser five distinguishing characteristics of Autonomy, Belonging, Connectivty, Diversity, and Emergence. The outcome of this research would influence further studies on the topic and greatly contribute to the SoSE body of knowledge.Alex Gorod, Brian Sauser, John Boardma

Application of case studies to engineering management and systems engineering education
No full textAs engineering system complexity has increased over the years, numerous complex systems projects have failed due to the lack of an appropriate systemic perspective. Since the solution to this challenge is itself a complex system, educating and training our current and future technical leaders on these challenges, and providing suggested changes in their mind sets, is imperative. As an educational tool, case studies can be a platform through which the analysis, knowledge application, and drawing of conclusions can occur to facilitate coping with the most complex systems. Case study learning has proven successful in the training of business leaders with real life examples of the strategies and tactics used by leading businesses to succeed globally. A valuable characteristic of case studies is that they support a holistic understanding and interpretation of the systems of action or interrelated activities engaged in by the participants. However, case studies are not as broadly used in engineering management and systems engineering education. This paper describes the importance of case studies to engineering management and systems engineering education, discusses frameworks for their implementation, and presents a case study template that can be used as a guideline in engineering education. © 2012 American Society for Engineering Education.S.

A Multi-Methodology Study of the Historic Impact of Soft Systems Methodology and Its Associated Data Visualization Approach in the Context of Operations and Business Strategy
No full textThe purpose of this three-essay dissertation was to expand knowledge and theory regarding soft systems methodologies (SSMs) and data visualization approaches in business, engineering, and other social sciences. The first essay depicts a bibliometric analysis study of the historic impacts of SSM from 1980-2018 on business, engineering, and other social sciences fields. This study found 285 articles that described or employed SSM for research and included outcomes such as top SSM authors, author citation impacts, common dissemination outlets, time-bound distribution of publications, and other relevant findings. This study provided a picture of who, what, why, when, and where SSM has had the greatest impact on academic thought and practice. The second essay presents research on the academic impact of Systemigrams, an associated data visualization approach, finding examples of conceptual or research development that employed Systemigrams to depict complex problem situations. Recommendations for improvement of designing these data visualizations to increase their field use resulted from this study. The final essay leverages a selection of the articles as use cases to produce a grounded theory study to identify phenomena that arose from the use of SSM for operations and firm strategy research. This study identified two broad themes including (i) scope, structure, and process challenges and (ii) performance and evaluation limitations. These themes were explained by six patterns that emerged from the publications. Each produced change recommendations for SSM process, practice, and reporting to support its continued viability and adoption in business and operations research

Value: An Examination of Its Key Dimensions and Elements through the Lens of Service-Dominant Logic and Beyond
No full texthis dissertation advocates that value and its creation are often misunderstood concepts since both lack robust comprehensive conceptual foundations from which to advance rigorous theoretical development and analysis. Furthermore, this dissertation characterized value as the subjective assessment of the total worth of benefits received for the price paid or costs, i.e. money, time, energy, etc. The purpose of this dissertation was to conduct a holistic examination of value through the lens of service-dominant logic (S-D) and several historical economic periods of thought.
I conducted a comprehensive S-D literature review in conjunction with a conceptual Boardman Soft Systems Methodology to develop a systemigram that captured the most critical S-D concepts and interrelationships to clarify its purpose and future research opportunities. During this process, value was recategorized and simplified into five primary dimensions, i.e. nature, perspectives, measures, storage, and creation. I employed Maslow's hierarchy of needs theory to illustrate that value at the lowest level of abstraction is the efficient satisfaction of human needs. I also investigated value creation and introduced a comprehensive value creation conceptual framework. Value creation is seen as a continuum of activity of key processes, i.e. value co-production, value in exchange, and value co-creation, and key procedural elements, i.e. actors, resource integration, ecosystems, services exchange, institutions and institutional arrangements as essentials to value creation. In addition, this dissertation also presented a Leyden value concept to the S-D lexicon. This concept complements use-value to capture associate upstream co-production activities and efforts as stored potential value.
This dissertation then employed this conceptual framework to perform two survey based empirical studies. The first tested Lusch et al. (2007) value-co-production framework and incorporated other constructs such as transaction cost, satisfaction, and future purchase intent into a single testable model. This study leveraged covariance based structural equation modeling with 477 respondents to simultaneously test the proposed model and advance Self Determination Theory and Transaction Cost Economics within the realm of value creation and S-D Logic. This research found that most of Lusch et al. (2007) hypotheses were supported and found statistical support for the inclusion of transaction cost as a construct that influences value-co-production. In addition, this study illustrated that value-co-production has a positive statistical association with satisfaction and its impact on consumer future purchase intent. Managerial, this study highlighted those customer characteristics and behaviors necessary to maximize value generation during co-production opportunities.
Finally, this dissertation empirically investigated the importance of benefits and equivalent cost reductions to entice consumer purchase intention across two different products and services scenarios. In total, this research gathered over 2,500 observations through a series of eight between subject survey experiments. This research found that consumers choose benefits such as warranty enhancements for new vehicle purchases and complementary desserts for dining experiences to enhance purchase intention. In addition, this research often revealed that consumers significantly decrease purchase intention when offered small value enhancements, i.e. 1% price reductions. This research also discovered that narcissism is negatively associated with those consumers who chose a donation to social causes. Finally, enhanced value offerings for expensive vacations, either through benefit enhancements or cost reductions, fail to significantly impact consumer purchase intention. The results of this research advance rational choice theory into the realm of value creation and S-D. Managerially, this research found that benefits, whether singular or offered as a menu, are powerful tools for retailers to employ to enhance consumer purchase intention

Understanding the Significance of Patient Empowerment in Health Care Services and Delivery
No full textTo address emerging challenges in empowering patients through telehealth, this dissertation has the following objectives: (a) find the key characteristics that enable patient empowerment [PE], (b) determining when will PE work as a solution, (c) find the optimal telehealth care method that enables PE, and (d) evaluate the impact of telehealth on health care outcomes (such as, patient satisfaction, patient trust with primary care providers, etc.) that ultimately enhances PE. These objectives are addressed in three studies presented here as three essays. Collectively, these essays contribute to the knowledge on PE, patient trust, and telehealth by providing insights on leveraging PE towards better health care services and delivery systems. Essay 1 aims to systemically map the concept of PE using principles of systems thinking with the Boardman soft systems methodology that enables a graphical visualization (i.e., systemigrams). Essay 2 investigates the practical and theoretical implications of connecting patients to empowerment care plans and minimizing wait times in healthcare service delivery using electronic prescriptions (s-scripts), phone calls, and video calls. In Essay 3, the mediating role of telehealth services between patient empowerment and patient satisfaction was analyzed, along with patient trust was assessed as a moderator between telehealth usability and patient satisfaction. Two hundred sixty-two responses from patients in North America with chronic illnesses were collected through an online survey questionnaire were analyzed using partial least squares-structural equation modeling (PLS-SEM). The findings of the research show that patients with chronic illnesses in North America feel empowered by using telehealth as they can get diagnosis of the illness even in remote areas and face no obstacle

Effects of Managerial Risk Propensity and Risk Perception on Contract Selection: Revisiting the Risk Neutrality Assumption of Transaction Cost Economics (TCE)
No full textContract selection is at the forefront of risk management and mitigation, yet it is an underrepresented area of research in supply chain management field as well as the influences of individual-level risk propensity and risk perception on supply chain decision-making processes. This dissertation explores effects of managerial risk propensity and risk perception on contract selection through the theoretical lens of Transaction Cost Economics (TCE), using a vignette-based experimental research design. This body of work introduces both a first-ever systemmigram of TCE in relation to contract selection, and a novel measurement scale for TCE contract typology. Furthermore, this dissertation tests the TCE predictions towards contract selection and explores the moderating role of financial risk propensity and risk perception (cost vs. supplier performance) on contract selection. The main theoretical contribution of this research is the opening of an old debate on the risk neutrality assumption of TCE, by providing empirical evidence that individual-level risk propensity and perception effect contract selection. The practical implications are significant and points out to the need for a better fit between individual-level and firm-level risk propensity
