Supply chain resilience refers to the capability of a supply chain to both withstand and adapt to unexpected disturbances. In today's turbulent business environment, firms are continually seeking to create more resilience within their supply chain through increased information communication technology use and enhanced business-to-business relationships. The focus of this dissertation is the investigation of how information communication technology creates resilience at the differing process levels of supply chain operations. Past research into information communication technology use within supply chains has often been conducted at the macro-level of supply chain phenomena. As such, there is still much to understand about how decision-makers interact with information communication technology at the micro-level of supply chain decision-making. A more in-depth, broad coverage of this interaction will provide both practitioners and academics a better understanding of how to leverage information communication technology in achieving supply chain resilience. To meet this aim, this dissertation contains three essays that re-orient conceptual thinking about supply chain phenomenon, explore how advances in information communication technology influence business-to-business relationships, and identify how information communication technology effects the decision-making of supply chain managers.

The 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.

To 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.
