Virtual patient design : exploring what works and why : a grounded theory study

Objectives: Virtual patients (VPs) are online representations of clinical cases used in medical education. Widely adopted, they are well placed to teach clinical reasoning skills. International technology standards mean VPs can be created, shared and repurposed between institutions. A systematic review has highlighted the lack of evidence to support which of the numerous VP designs may be effective, and why. We set out to research the influence of VP design on medical undergraduates. Methods: This is a grounded theory study into the influence of VP design on undergraduate medical students. Following a review of the literature and publicly available VP cases, we identified important design properties. We integrated them into two substantial VPs produced for this research. Using purposeful iterative sampling, 46 medical undergraduates were recruited to participate in six focus groups. Participants completed both VPs, an evaluation and a 1-hour focus group discussion. These were digitally recorded, transcribed and analysed using grounded theory, supported by computer-assisted analysis. Following open, axial and selective coding, we produced a theoretical model describing how students learn from VPs. Results: We identified a central core phenomenon designated ‘learning from the VP’. This had four categories: VP Construction; External Preconditions; Student–VP Interaction, and Consequences. From these, we constructed a three-layer model describing the interactions of students with VPs. The inner layer consists of the student's cognitive and behavioural preconditions prior to sitting a case. The middle layer considers the VP as an ‘encoded object’, an e-learning artefact and as a ‘constructed activity’, with associated pedagogic and organisational elements. The outer layer describes cognitive and behavioural change. Conclusions: This is the first grounded theory study to explore VP design. This original research has produced a model which enhances understanding of how and why the delivery and design of VPs influence learning. The model may be of practical use to authors, institutions and researchers

Business model innovation influencing factors : an integrative literature review

Proposal to integrate the Business Model Innovation (BMI) influencing factors in a single framework. Twelve BMI influencing factors found through an integrative literature review. Factors grouped through an affinity diagram to design the framework architecture, containing four categories. The study highlights the importance for companies to consider the interrelationship between the influence factors to be successful in their BMI initiatives. This paper aims to provide an integrated framework that comprises influence factors for business model innovation, and describe them by exploring the linkages between different factors. An integrative literature review was conducted using PRISMA work flow to manage this kind of methodology. This work finds 12 main potential influence factors for business model innovation. All factors have been grouped into four different categories, using the affinity diagram approach. Business model innovation is a recent research topic, and not all its influence factors are agreed upon. Despite the importance of grouping, those already described in a single framework, there may be other relevant factors not mapped. Despite the existence of bibliographic material on specific influencing factors, there is, to the best of the authors’ knowledge, no study that integrates all the explored factors. This work contributes to literature by integrating the diverse factors into a single framework. It contributes to practice, enticing managers to reflect on their own environment, and on the possible paths to follow for succeeding with its business model innovations efforts15461061

Creating a culture for radical innovation in a small mature business

This article describes an approach in organizational development to develop an innovation culture for radical product development in a small mature engineering company. The research took place in a business based in the United Kingdom that designed and manufactured instrumentation and specialized packing machines. An initial study within the company’s new product development team identified key aspects that influenced a radical innovation culture. Nine key themes were found to be pertinent, following an iterative process with the development team. These themes were triangulated using the established Organization Culture Assessment Instrument and the Creative Climate Assessment Tool. A third assessment was developed that gauged the development team culture proximity to an ideal position. Seven interventions were developed in conjunction with the company development team, senior managers, the analysis of previous empirical case research and dialogue with UK companies that promote discontinuous innovation. The results of the interventions were evaluated 4 years after implementation. The culture was re-assessed using the same assessment tools and the changes were identified. The outcomes are described and they indicate the success of the company’s attempt to embed a sustainable radical innovation culture into the product development area

What are the impacts of implementing ISOs on the competitiveness of manufacturing industry in China?

Based on the proposed ‘PIE’ analytical framework, this paper argues that the preparation, implementation and evaluation of international standards (ISOs) affect the competitiveness of (foreign-financed) export-oriented manufacturing industry in southern and southeastern China, both in the short- and long-term. During the period of preparation, the decision to adopt ISOs is mainly driven by market demand and/or by the decisions of established competitors. Negative effects due to the diversion of scarce resources and institutional resistance to change during the period of transitional implementation are offset by the overall enhancement of the firm's productivity in the long run. ‘Tailoring for the external audit’ and ‘second-best’ practices are two strategies commonly employed by Chinese firms to lower the transaction costs involved in ISO audits

Knowledge flow across inter-firm networks: the influence of network resources, spatial proximity, and firm size

The objective of this paper is to analyze the characteristics and nature of the networks firms utilize to access knowledge and facilitate innovation. The paper draws on the notion of network resources, distinguishing two types: social capital – consisting of the social relations and networks held by individuals; and network capital – consisting of the strategic and calculative relations and networks held by firms. The methodological approach consists of a quantitative analysis of data from a survey of firms operating in knowledge-intensive sectors of activity. The key findings include: social capital investment is more prevalent among firms frequently interacting with actors from within their own region; social capital investment is related to the size of firms; firm size plays a role in knowledge network patterns; and network dynamism is an important source of innovation. Overall, firms investing more in the development of their inter-firm and other external knowledge networks enjoy higher levels of innovation. It is suggested that an over-reliance on social capital forms of network resource investment may hinder the capability of firms to manage their knowledge networks. It is concluded that the link between a dynamic inter-firm network environment and innovation provides an alternative thesis to that advocating the advantage of network stability

Business Model Innovation and Factors Influencing Business Model Innovation

Thesis purpose: The thesis aims to explore business model innovation in companies and the main factors having influence on the decision making process towards business model innovation. The thesis addresses a gap in the literature in regards to the main factors having impact on business model innovation and their interdependence.Theoretical perspectives: Key concepts of this study are business model innovation and factors influencing business model innovation (Amit & Zott 2001; Chesbrough, 2010; Demil and Lecocq, 2010; Sako, 2012).Conclusions: It has been revealed that there are a few main factors having impact on decision making towards business model innovation. These factors have been divided into drivers and barriers. And while literature discusses mainly barriers for business model innovation, we have explored both, drivers and barriers. They influence in opposite directions to business model innovation. The empirical findings in Skanska Oresund reflected argument of Johnson et al. (2008) that business model innovation should be undertaken only when companies are able to make sure that the opportunity is large enough to warrant the effort and risk.Methodology: A case study design was picked for the purpose of exploring the topic stated. A four months internship in a company provided the authors with conditions to explore in-depth the phenomenon. Iterative approach has been employed, meaning that data collection and analysis were done simultaneously and referred back to each other during the process. This approach helped the authors to explore factors more comprehensively, including those identified in extant literature as well as new emerging ones, and to identify important patterns. This approach also allowed the authors to adjust the method during the data collection, which is a key feature of theory building case study. The empirical data collection was effectuated through semi-structured interviews. At the end this research aims to contribute to the literature by filling the gap identified

탐험적 혁신을 촉진하는 기업의 내·외부적 지식요인에 대한 연구

학위논문(박사) -- 서울대학교대학원 : 공과대학 협동과정 기술경영·경제·정책전공, 2023. 2. 강진아.Exploratory innovation, which refers to the generation of something valuable by using unfamiliar knowledge obtained from exploration, has received considerable attention as an important way to gain a competitive advantage and achieve sustainable growth. The increased importance of exploratory innovation resulted in the growing interest in underlying mechanisms of innovation, such as knowledge exploration (i.e., a nonlocal search beyond the firm's current expertise) and recombinatory search framework (i.e., an analytic tool that explains the link between knowledge elements and innovation). Recently, literature on exploratory innovation has investigated a firms internal and external knowledge environments on promoting exploratory innovation with the mechanisms of innovation as an implicit premise. However, the research on exploratory innovation is still in its early stages and has focused on individual topics rather than analyzing the entire process by which a firm creates exploratory innovation. In this regard, there is room to develop the previous discussions by taking a closer look at this field. This dissertation aims to increase the academic understanding of the mechanisms of exploratory innovation by investigating two key questions: First, what characteristics of a firm's intrinsic and embedded knowledge base promote exploratory innovation?; because the knowledge base is embedded in the organization and exists in a complex form changing over time, it is necessary to consider it a dynamic collection that includes knowledge elements and their combinations rather than a simple repository of knowledge elements, Second, what is the effective way to source external knowledge among alliance partner firms to create exploratory innovation?; when considering the external knowledge environment to promote exploratory innovation, it is necessary to understand not only the compositions of external knowledge resources but also the structural factors of interfirm networks, which affect accessibility and appropriability for external knowledge resources. From the internal focus, previous research on exploratory innovation has primarily focused on investigating and explaining a firms internal knowledge base as a simple repository of knowledge elements. Concerning the structure of knowledge, only recently has research begun to investigate characteristics of a knowledge base as a network of knowledge elements. In this regard, this dissertation examines the firms internal knowledge network and its effects on the subsequent exploratory innovation. Chapter 3 suggests a theoretical framework to express a firm's knowledge base as a single network composed of knowledge elements (i.e., component knowledge) and their combinations (i.e., architectural knowledge) and investigate the dynamics of such a knowledge network over time. Specifically, Chapter 3 distinguishes accumulated component and architectural knowledge, and investigates their impact on subsequent exploratory innovation, i.e., the creation of new elements and new combinations. The uncovered relationships between the two types of accumulated knowledge and the two types of exploratory innovations, help us comprehend the dynamics of the firms knowledge network. Using patent data of 111 US semiconductor companies from 2000–2010, Chapter 3 empirically verifies an inverted U-shape relationship between the level of accumulated architectural knowledge and subsequent new knowledge combinations. As a firm accumulates experience of combining knowledge resources, new ways of knowledge application occur more frequently. This accumulated architectural knowledge helps organizational learning and broadens knowledge applicability to foster exploratory innovation. However, because of path-dependent attributes, knowledge application becomes rigid inertia that makes it harder to seek new ways. Furthermore, the relationships between accumulated component knowledge and new knowledge combinations, and between accumulated architectural knowledge and new knowledge elements were found to be positive. It shows that the accumulation of component knowledge can be essential for creating new knowledge combinations, and the accumulation of architectural knowledge also helps form new knowledge elements. In other words, learning about elements as a basis for new inventions should precede the creation of new inventions by combining elements. Additionally, accumulating knowledge from the experience of combining various elements is important to extend a firms area of expertise by gaining new knowledge elements. The results highlight the important role of the firms accumulated knowledge resources in creating exploratory innovation and contribute to the research on the antecedents of exploratory innovation. From the external focus, this dissertation investigates how the focal firm is able to effectively discover and secure the necessary knowledge in the alliance portfolio to create exploratory innovation. Previous literature has primarily focused on examining the external knowledge environment for exploratory innovation, focusing on either the compositions of knowledge resources or the structural factors affecting firms' access to them. For a holistic approach, Chapter 4 proposes a new framework of knowledge flow and search flexibility, both are essential for exploratory innovation, to simultaneously examine the effects of a firm's network position and knowledge composition of the alliance portfolio. Using this framework, Chapter 4 empirically confirms that central and brokering positions have an inverted U-shape relationship with the creation of exploratory innovation through panel data of 142 pharmaceutical companies from 1996-2010. Specifically, a central position promotes smooth knowledge flow due to the focal firms high social status, allowing it to access valuable knowledge from its partners. However, exceeding a certain level, the central position decreases search flexibility due to the constraint on decision-making caused by strong relationships. A brokering position fosters search flexibility as it allows the focal firm to control information flows. However, exceeding a certain level, the lack of absorptive capacity negatively influences knowledge flow. Chapter 4 also verifies two combinations of network position and knowledge composition advantageous for increasing exploratory innovation: a central position with partners' wide scope of new knowledge, and a brokering position with partners' wide scope of shared knowledge. These results support the argument that the effects of network position and knowledge composition can complementarily interact with each other, thus potentially compensating the negative effects on either knowledge flow or search flexibility. Specifically, new knowledge breadth can increase the low search flexibility resulting from a central position. The central position allows firms to overcome the information overflow associated with increases in new knowledge breadth. The shared knowledge breadth with partners increases absorptive capacity, which helps firms to understand each other and increases the knowledge flow that is often insufficient for firms at a brokering position. At the same time, the brokering position can prevent firms from becoming too similar to its partners, which would harm the exploration of new ideas. From these results, Chapter 4 contributes to the literature by identifying interaction effects between social network theory and the knowledge-based view and suggests implications for designing a firm's alliance strategy. Overall, this dissertation increases the understanding of the mechanism of exploratory innovation by investigating a firms internal and external factors that influence the creation of exploratory innovation. It provides the following contributions and implications. First, based on the findings of Chapter 3, this dissertation extends the literature on a firms knowledge resources as a source of innovation by revealing the relationship between knowledge elements and combinations. Applying Henderson and Clark(1990)s framework, the firms knowledge network and its subsequent exploratory innovation can be depicted to accumulated component and architectural knowledge and creation of new knowledge elements and combinations. Furthermore, by linking the firms previously formed knowledge network and its subsequent innovation, these relationships allowed us to explore the dynamics of a knowledge network in which existing elements and combinations are influencing each other to form new knowledge elements and combinations over time. Second, based on the findings of Chapter 4, this dissertation extends the literature on alliance portfolios by simultaneously employing social network theory and the knowledge-based view. Most prior studies examined the characteristics of the alliance portfolio either by focusing on structural properties such as actors network position or by focusing on nodal properties such as actors knowledge resources. However, this separation limits the understanding of inter-relational effects between the network position and the knowledge composition in alliance portfolios. This study highlights this inter-relationship and suggests that the potential disadvantageous effects originating from a firms network position can, under specific conditions, be overcome through a suitable knowledge composition. Third, this dissertation contributes to innovation literature by addressing a new approach satisfying two key factors for the creation of exploratory innovation, i.e., knowledge flow and search flexibility. Prior studies state that a knowledge flow corresponds with strong relationships, while search flexibility is associated with weak relationships. As both knowledge flow and search flexibility are required for exploration, prior studies focused on finding the optimum level of organizational integration or the relevant strategic choice. However, this dissertation claims that a particular combination between a firms network position and the knowledge composition of its alliance portfolio can complement both factors shortcomings, ultimately satisfying both key factors simultaneously.탐험적 지식을 활용해 가치 있는 것을 만들어내는 탐험적 혁신은 경쟁 우위를 확보하고 지속 가능한 성장을 이룰 수 있는 중요한 방법으로 상당한 관심을 받아왔다. 탐험적 혁신의 중요성이 높아짐에 따라 지식 탐험과 재조합 검색 프레임워크와 같은 혁신의 기본 메커니즘에 대한 관심이 높아지고 있으며 최근에는 이러한 혁신 메커니즘을 바탕으로 탐험적 혁신을 촉진하는데 필요한 기업의 지식 환경에 초점을 맞춘 연구가 등장하고 있다. 그러나 탐험적 혁신에 대한 연구는 아직 초기 단계에 있으며 기업이 탐험적 혁신을 창출하는 전체 과정을 분석하기보다는 개별 주제에 초점을 맞추고 있다. 그런 점에서 이 분야는 좀 더 면밀한 연구를 통해 기존 문헌의 논의를 발전시킬 여지가 있다. 본 논문은 다음 두 가지 핵심 질문을 제시함으로써 탐험적 혁신 메커니즘에 대한 학문적 이해를 높이는 것을 목표로 한다. 첫째, "기업에 내재된 지식 기반의 어떤 특징이 탐험적 혁신을 촉진하는가?"; 기업의 지식 기반은 조직, 시스템, 사람 등에 내재되어 복잡한 형태로 존재하고 시간이 지남에 따라 변화하기 때문에 단순한 지식 요소의 저장소가 아닌 지식 요소 및 이들의 조합을 포함하는 동적 집합체라고 간주할 필요가 있다. 둘째, "탐험적 혁신을 창출하기 위해 제휴 파트너 기업들 사이에서 그들이 가진 지식을 얻는 효과적인 방법은 무엇인가?"; 탐험적 혁신을 촉진하기 위해 외부 지식 환경을 고려할 때, 외부 지식 자원의 구성뿐 아니라 외부 지식 자원의 접근성과 전유성에 영향을 미치는 기업 간 네트워크의 구조적 요인도 이해할 필요가 있다. 내부적 관점에서, 탐험적 혁신에 대한 기존 연구는 기업의 내부 지식 기반을 주로 단순한 지식 요소의 저장소로 조사하고 설명하는 데 초점을 맞추었으며 최근에서야 지식 요소의 구조적 특성을 조사하기 위한 연구가 시작되었다. 이와 관련하여 본 논문은 기업의 내부 지식 네트워크가 탐험적 혁신에 미치는 영향을 살펴본다. 제3장은 기업의 지식 기반을 요소 지식(=component knowledge)과 이들의 조합(구조 지식=architectural knowledge)으로 구성된 네트워크로 표현하고 이러한 지식 네트워크가 시간에 따라 어떻게 변화해 가는지 조사하기 위한 이론적 프레임워크를 제안한다. 구체적으로, 제3장에서는 축적된 요소 지식 및 구조 지식을 구별하고, 이로 인해 발생하는 탐험적 혁신, 즉 새로운 요소 지식 및 새로운 구조 지식(요소 지식간 새로운 조합)에 미치는 영향을 조사한다. 두 가지 유형의 축적된 지식과 두 가지 유형의 탐험적 혁신 사이의 드러나지 않은 관계는 회사의 지식 네트워크의 동적 특성을 이해하는 데 도움이 된다. 제3장에서는 2000~2010년 미국 111개 반도체 기업의 특허자료를 이용하여 축적된 구조 지식의 수준과 그에 따른 새로운 구조 지식 간의 역 U자형 관계를 실증적으로 검증한다. 기업이 지식 결합 경험을 축적함에 따라 새로운 지식 적용 방법을 발견하며, 이렇게 축적된 구조 지식은 조직 학습 및 지식 적용 가능성을 확장하여 탐험적 혁신(구조 지식의 발생)을 촉진한다. 그러나 구조 지식이 축적될수록 조직 학습의 경로 의존적 속성에 따른 경직된 관성이 생기게 되고 새로운 지식 응용 방법을 모색하는 것이 어렵게 된다. 한편으로, 축적된 요소 지식과 새로운 구조 지식, 그리고 축적된 구조 지식과 새로운 요소 지식 간의 관계는 양(+)의 방향으로 나타났다. 이는 요소 지식 축적이 새로운 지식 조합(구조 지식)을 만드는 데 필수적일 수 있으며, 구조 지식 축적이 새로운 요소 지식을 형성하는 데 도움이 된다는 것을 말해준다. 즉, 새로운 발명(지식 요소의 결합)을 하기 위해서는 개별 지식 요소에 대한 학습이 선행되어야 하며, 반대로 새로운 요소 지식을 획득함으로써 기업의 전문 영역을 확장하려면 다양한 요소 지식 결합 경험이 중요하다는 결과를 도출하였다. 이 결과는 기업이 축적한 지식 자원이 탐험적 혁신 창출에 미치는 영향을 강조하고 기존 탐험적 혁신에 대한 문헌 연구에 기여한다. 외부적 관점에서는, 어떻게 포컬 기업이 탐험적 혁신을 창출하기 위해 제휴 포트폴리오에서 필요한 지식을 효과적으로 발굴하고 확보할 수 있는지 조사한다. 기존 문헌은 탐험적 혁신을 위한 외부 지식 환경을 설명하기 위해 주로 지식 자원의 구성 또는 지식 자원 접근에 영향을 미치는 구조적 요인에 초점을 맞추어 조사하였다. 통합적 접근방식을 위해, 제4장은 기업의 네트워크 위치와 제휴 포트폴리오의 지식 구성 영향을 동시에 조사하기 위해 탐험적 혁신에 필수적인 두 가지 요소, 즉, 지식 흐름(knowledge flow)과 검색 유연성(search flexibility) 프레임워크를 제안한다. 제4장은 이러한 틀을 이용하여 1996~2010년 142개 제약회사의 패널 자료를 통해 중심 위치 및 중개 위치가 탐험적 혁신의 창출과 역 U자형 관계를 맺고 있음을 실증적으로 확인한다. 중심 위치는 높은 사회적 지위로 인해 원활한 지식 흐름을 촉진하여 파트너로부터 귀중한 지식을 접할 수 있도록 돕는다. 그러나 일정한 수준을 넘어서면 중심 위치는 강한 관계에서 발생하는 의사 결정 제약으로 인해 검색 유연성을 떨어뜨린다. 중개 위치는 포컬 기업이 정보 흐름을 제어할 수 있도록 하기 때문에 검색 유연성을 높인다. 그러나 일정 수준을 넘어서는 경우 흡수능력 부족으로 지식 흐름에 부정적인 영향을 미치게 된다. 제4장에서는 또한 탐험적 혁신을 증가시키는데 유리한 네트워크 위치와 지식 구성의 두 가지 조합, 즉 중심 위치와 넓은 범위의 새로운 지식을 보유한 파트너, 중개 위치와 넓은 범위의 공유 지식을 보유한 파트너 사이의 관계를 검증한다. 이러한 결과는 네트워크 위치와 지식 구성의 영향이 상호 보완적으로 상호 작용하여 지식 흐름 또는 검색 유연성에 대한 부정적인 영향을 잠재적으로 보상할 수 있다는 주장을 뒷받침한다. 넓은 범위의 새로운 지식은 중심 위치에서 기인하는 낮은 검색 유연성을 증가시킬 수 있다. 중심 위치의 구조적 장점을 이용해 포컬 기업은 새로운 지식의 범위가 증가할 때 발생할 수 있는 정보의 범람을 극복할 수 있다. 파트너와 넓은 범위의 지식을 공유할 경우 상대적인 흡수 능력을 증가시켜 기업이 서로를 이해하는 데 도움이 되고 중개 위치에 있는 기업에게 종종 부족한 지식 흐름을 증가시킨다. 동시에, 중개 위치는 포컬 기업이 파트너들과 너무 비슷해지는 것을 막아줌으로써 새로운 아이디어 탐구에 미칠 수 있는 부정적 영향을 줄인다. 이러한 결과로부터, 제4장은 소셜 네트워크 이론과 지식 기반 관점의 상호작용 효과를 확인함으로써 기존 문헌 연구에 기여하고 기업의 제휴 전략 설계에 대한 시사점을 제시한다. 종합하면, 본 논문은 탐험적 혁신 창출에 영향을 미치는 기업의 대내외적 지식 요인을 조사함으로써 탐험적 혁신 메커니즘에 대한 이해를 높이고 다음과 같은 시사점을 도출한다. 첫째, 본 논문은 제3장의 연구결과를 바탕으로 지식 요소와 지식 결합의 관계를 밝히고 혁신의 원천으로서의 지식 자원에 대한 기존 문헌을 확장한다. 헨더슨과 클라크(1990)의 프레임워크를 적용하면, 회사의 지식 네트워크와 탐험적 혁신은 축적된 요소 지식 및 구조 지식과 새로 발생하는 요소 지식 및 구조 지식으로 묘사될 수 있다. 이러한 관계를 통해 형성된 기업의 지식 네트워크와 혁신 창출을 연계함으로써 시간이 지남에 따라 기존 요소 지식과 구조 지식이 서로 영향을 미쳐 새로운 요소 지식 및 구조 지식을 형성하는 지식 네트워크의 동적 특성을 탐색할 수 있었다. 둘째, 본 논문은 제4장의 연구결과를 바탕으로 소셜 네트워크 이론과 지식기반 관점을 동시에 적용하여 제휴 포트폴리오에 대한 기존 문헌을 확장한다. 많은 선행 연구는 행위자의 네트워크 위치와 같은 구조적 특성에 초점을 맞추거나 행위자의 지식 자원과 같은 노드적 특성에 초점을 맞추어 제휴 포트폴리오 특성을 조사하였다. 그러나 제휴 포트폴리오에서 네트워크 위치와 지식 구성 간 상호 관계에 대한 연구는 제한적이었다. 본 연구는 이러한 상호 관계를 초점을 맞추고, 특정 조건 하에서는 기업의 네트워크 위치에서 비롯되는 부정적 영향을 적절한 파트너의 지식 구성을 통해 극복할 수 있음을 시사한다. 셋째, 본 논문은 탐험적 혁신 창출을 위한 두 가지 핵심 요소, 지식 흐름과 검색 유연성을 만족시켜야 한다는 새로운 논의를 제안함으로써 기존 혁신 문헌연구에 기여한다. 이전 연구에서 지식 흐름은 강한 관계에서 발현하기 쉽고 검색 유연성은 약한 관계에 비롯된다고 말한다. 탐험적 혁신을 위해서는 지식 흐름과 검색 유연성이 모두 요구되기 때문에 선행연구는 최적의 조직통합 수준이나 적절한 전략적 선택을 찾는 데 초점을 맞췄다. 그러나 본 논문은 제휴 포트폴리오에서 포컬 기업의 네트워크 위치와 파트너 지식 구성 간 특정 조합이 두 요소의 단점을 보완하여 궁극적으로 두 가지 핵심 요소를 동시에 만족시킬 수 있음을 밝힌다.Chapter 1.
