This article investigates the values and barriers influencing the adoption and acceptance of telemedicine services during COVID-19 by a systems approach combined with a quantitative analysis. We developed a casual loop diagram showing the interactions between the factors, including technology, policymaking, patient, and care provider in the context of COVID-19. The feedback loops were thematically synthesized from the literature to demonstrate the attitude of adopting telemedicine services while considering the connections and causality of different factors. To further quantify how COVID-19 impacted the adoption of telemedicine, a National Electronic Health Record Survey 021 was utilized to test the usage, barrier, and trend of telemedicine. The results indicate that factors including ease of use, utilization, available tools, facilitating conditions, technology access, and quality of care influence the adoption and acceptance of telemedicine. The results also suggest that the challenges and opportunities associated with telemedicine adoption and use should be explored holistically from multiple perspectives and shed light on various stakeholders at different levels.","PeriodicalId":100632,"journal":{"name":"IEEE Open Journal of Systems Engineering","volume":"1 ","pages":"38-49"},"PeriodicalIF":0.0,"publicationDate":"2023-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/iel7/9745883/10043029/10097547.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67872585","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are many existing methods and commercial tools for providing context and traceability from requirements and specifications to a system's artifacts, but these tools are often vendor locked, require access to cloud-based services, and necessitate high licensing costs. Furthermore, modern large-scale system development involves multiple business partners, each of which needs to ensure their teams have granular, role-based access to all relevant information without impediment; centralized warehousing and gatekeeping should not be handled by a single entity if the information is to remain readily accessible. Instead, a permissioned, distributed knowledgebase that avoids vendor lock-in enables a consistent, real-time view of information that provides equivalent context for developers and other stakeholders. ChaordicLedger, a free and open-source project, joins the transparency and smart contract aspects of distributed ledger technology with the storage capabilities of a distributed file system to fulfill this industrial application while allowing for industry-specific customizations.","PeriodicalId":100632,"journal":{"name":"IEEE Open Journal of Systems Engineering","volume":"1 ","pages":"60-67"},"PeriodicalIF":0.0,"publicationDate":"2023-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/iel7/9745883/10043029/10089470.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67871602","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Rapid Assessment Procedure as a Tool for Front-End Stakeholder Needs Analysis in Engineering Projects","authors":"Casey Gibson;Jessica Smith;Kathleen Smits;Juan Lucena;Oscar Jaime Restrepo Baena","doi":"10.1109/OJSE.2023.3275379","DOIUrl":"https://doi.org/10.1109/OJSE.2023.3275379","url":null,"abstract":"Front-end stakeholder needs analysis is increasingly recognized as an essential component of sustainable engineering projects, yet most engineering curricula only cover this topic superficially. Fields such as humanitarian engineering have long recognized the importance of stakeholder needs analysis for the success of development interventions, and researchers have developed best practice frameworks for engaging stakeholders that can be applied to systems engineering. These frameworks rely on established social science techniques, such as ethnography and inductive reasoning, and humanitarian engineering principles, such as contextual listening and sociotechnical thinking, to facilitate comprehensive needs assessments. While conventional ethnographies are often incompatible with engineering projects’ timelines and expertise, anthropologists have developed methodologies to overcome these limitations, such as rapid assessment procedure. While widely applied in the public health sector, rapid assessment procedure has been seldom integrated with engineering projects. Rapid assessment procedure, combined with humanitarian engineering principles, can help researchers quickly gain a nuanced understanding of relevant aspects of complex sociotechnical systems. This article seeks to introduce systems engineers to humanitarian engineering rapid assessment procedure as a concrete technique for conducting comprehensive front-end stakeholder needs analysis. In this article, a case study is presented on the teaching and implementation of humanitarian engineering rapid assessment procedure in a workshop with a group of undergraduate engineering students. We sought to analyze students' perceptions of and learning outcomes from the workshop. Student engagement and learning exceeded expectations, positioning humanitarian engineering rapid assessment procedure as a potentially valuable tool for systems engineers to analyze stakeholder needs to inform system design.","PeriodicalId":100632,"journal":{"name":"IEEE Open Journal of Systems Engineering","volume":"1 ","pages":"68-80"},"PeriodicalIF":0.0,"publicationDate":"2023-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/iel7/9745883/10043029/10123304.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67871603","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Urban Air Mobility Situation Awareness From Enterprise Architecture Perspectives","authors":"Raquel Hoffmann;Hidekazu Nishimura;Rodrigo Latini","doi":"10.1109/OJSE.2023.3252012","DOIUrl":"https://doi.org/10.1109/OJSE.2023.3252012","url":null,"abstract":"Urban air mobility (UAM) operation is currently under discussion by the industry, authorities, and society, dealing with new concepts, new technologies, and complex challenges. For UAM safety, it is fundamental to strive for high levels of correct decision-making among agents and services. In safety-critical systems like UAM transportation, it is crucial to secure situation awareness (SA). Systems engineers, architects, and organizations must plan for SA acquisition and maintenance from early concept studies to ensure the relevant information is shared, allowing good decision-making. The article proposes a new approach to represent SA in the UAM ecosystem using enterprise architecture (EA) modeling through the unified architecture framework (UAF). To understand the interactions and behaviors committed to SA, decision-making, and safe performance, SA is explored using a process driven by a comprehensive picture of an entire enterprise from the perspectives of designers, providers, and operators. The UAF modeling language and domain metamodel were used as the EA modeling methodology. The model proposed in this article presents a novel and comprehensive representation of SA in the UAM ecosystem. The different views from the model are explored to discuss how the SA can improve the safe accomplishment of UAM missions. The results include views combining people, data, operators, and operational processes showing how an enterprise support SA as a competence.","PeriodicalId":100632,"journal":{"name":"IEEE Open Journal of Systems Engineering","volume":"1 ","pages":"12-25"},"PeriodicalIF":0.0,"publicationDate":"2023-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/iel7/9745883/10043029/10058535.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67872583","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In model-based systems engineering, functional needs can be modeled by use case diagrams. Intended outcomes of system requirements definition include resolution of disagreement about requirements, explicit agreement between stakeholders, and traceability. However, stakeholder needs are often elicited in a siloed manner and may be inconsistent. The lack of mathematically based systematic approaches for requirements definition poses a challenge to model-based transformation of needs into a technical view of the system that achieves agreement between stakeholders. This article specifies and demonstrates mathematical frameworks for \u0000<italic>rationalizing</i>\u0000 and \u0000<italic>synthesizing</i>\u0000 functional needs that have been captured through an elicitation process.

However, existing math-based methods to plan verification strategies do not consider decisions to implement VAs and perform CA jointly, ignoring their close interrelationship. In this article, we present a joint verification–correction model to find optimal joint verification–correction strategies (JVCSs). The model is constructed so that both VAs and CAs can be chosen as dedicated decisions with their own activity spaces. We adopt the belief model of Bayesian networks to represent the impact of VAs and CAs on verification planning and use three value factors to measure the performance of JVCSs. Moreover, we propose an order-based backward induction approach to solve for the optimal JVCS by updating all verification state values. A case study was conducted to show that our model can be applied to effectively solve the verification planning problem.","PeriodicalId":100632,"journal":{"name":"IEEE Open Journal of Systems Engineering","volume":"1 ","pages":"1-11"},"PeriodicalIF":0.0,"publicationDate":"2022-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/iel7/9745883/10043029/09956024.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67872582","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
