With the development of digital technology related to mobile, cloud, IoT, even traditional businesses have began to develop strategies for digital transformation. This is regarded as a very important part for business sustainability. However, many of these attempts are being conducted from the management point of view, and there has been little research on user experience design for digital transformation. In this study, Starbucks, which started a offline store business and expanded its experience with online services, was selected as a representative case and user research was conducted on it. Through an usability evaluation and post-task interviews of the Starbucks mobile application users, we discovered important issues of user experience to consider when transforming and expanding services online from offline. Based on the findings, the considersations for designing online user experience were discussed and proposed.

The 21st century could be called the age of Experience Economy associated with the importance to external and internal experience of product users. It needs the understanding of customer's needs in new point of view. In the area of design development, it requires the extensive application of experience from traditional method that was based on the style and usability to more advanced concept. To correspond to these changes, we need to explore new customer's value system for knowledge-information design and systematic approaches to experience system. The purpose of this research is to define the concept of 'experience' newly in the importance side of customer's life, form a clear definition of experience design and present the model of application system. Theoretical frameworks of this research are based on the Empiricism and John Dewey's theory. By applying these frameworks make dear the concept of experience concept and reanalysis the meaning and style in the perspective of design. In this process, we can extract the main factors that inducing the experience, create new application system and model again to the field of design. Application model can creates various experiences through supplying different experience style and factors for customer, make customer realize experience object. Experience designs offer optimal experience to users by making a plan and design experience to user's goal.

When a product is designed, user's requirements should be well analyzed and applied to the design so that the psychological and aesthetic factors of a product can be accurately conveyed to consumers. The essence of product development is to analyze the changes in the purchasing tendency of consumers and the needs of times, find out user experiences to apply to a design, and establish the objective of product development that well considers those. Designing should be recognized as one that designs even the sensitivity and experience created in the relationship with users, beyond the conventional notion of design that it draws the physical form of a product. As the subjects that design should consider have expanded like this, it has become important that today's design provides a new experience as well as simply develops formative elements based on the functions of an object. As a result, it becomes impossible to accomplish such objective only with the traditional design process that existing designers have stuck to so far. In this respect, this study is aimed to draw out a system and methodology for a user-oriented design process so that design can provide expanded experience to users from product form, applied material, and service.

사용자 중심의 디자인 패러다임이 도래하면서 점차 사용성 진단이 제품 혹은 서비스의 전체 개발 프로세스 상에서 필수적인 절차이며 이를 통해 사용자의 경험 품질 향상을 모색할 수 있다는 인식이 확산되고 있다. 실제로도 제품 개발 과정의 한 꼭지로서 사용자 리서치를 수행하는 기업이 점차 증가되고 있지만, 리서치를 통해 도출된 결과가 실제 제품 개발에 얼마나 효과적으로 반영되는지에 대해서는 의문을 가지게 된다. 이러한 의문을 품게 된 이유는 사용자 리서치 결과가 실제 제품이나 서비스에 적용된 정도가 크지 않은 경우를 종종 목격하였기 때문이다. 이러한 주요 원인 중 하나로서 리서치 결과가 실무 담당자들에게 전달되는 과정에서 발생될 수 있는 해석 상의 차이 때문일 것이라는 가설을 가지고 사용성 진단 리서치 프로세스의 변화를 시도해 보았다. 다시 말하면, 실제 현장에서 단기간 동안 진행되는 사용자 리서치를 통해 보다 효과적으로 그 결과를 활용할 수 있는 방안으로 리서치 진행자와 실무 담당자간 협업 프로세스 작업 단계인 협업 디자인 워크샵(co-designing workshop)을 제안하였다. 본 연구는 협업 디자인 워크샵 프로세스의 소개를 목적으로 하였으며, 본 연구의 결과가 사용성 진단 리서치 결과의 활용도 및 가치를 향상시키고, 사용자의 입장을 대변하는 리서처의 책임과 역할을 충실히 수행하는데 도움이 될 수 있기를 기대한다.

The purpose of this study was to propose a "user experience (UX)-centered product development process" so that the product design development process using the service design process can be systematized and used in practice. In a situation in which usability research on office phones is lacking compared to general home phones, this study expands to a product-based service design point of view rather than simple product development, intending to research ways to provide user experience value through office phone design in smart office. This study focused on extracting UX-centered user needs using the service design process and developing product design that realizes user experience value. In particular, the service design process was applied to systematically extract user needs and experience value elements in the product development process and to discover ideas that were converged with product-based services. For this purpose, the "Double Diamond Design Process Model," which is widely used in the service design field, was adopted. In addition, a product design development process was established so that usability improvement plans, user experience value elements, and product-service connected ideas could be extracted through a work-flow in which real users and people from various fields participate. Based on the double diamond design process, in the "Discover" information collection stage, design trends were identified mainly in the office phone markets. In the "Define" analysis and extraction stage, user needs were analyzed through user observation, interview, and usability survey, and design requirements and user experience issues were extracted. Persona was set through user type analysis, and user scenarios were presented. In the "Develop" development stage, ideation workshops and concept renderings were conducted to embody the design, and people from various fields within the company participated to set the design direction reflecting design preference and usability improvement plans. In the "Deliver" improvement/prototype development/evaluation stage, a working mock-up of a design prototype was produced and design and usability evaluation were conducted through consultation with external design experts. It is meaningful that it established a "UX-centered product development process" model that converged with the existing product design development process and service design process. Ultimately, service design-based product design development process was presented so that I Corp.'s products could realize user experience value through service convergence.

The study is a user experience design study on the function of action cams used for leisure activities that have been on the rise recently. Along with the video platforms that are developing in a user-friendly way, the size of the action cam market is also growing. However, there is a lack of research on the quality of a function that enhances the user experience. Thus, this study classified action cam functions according to user experience elements by using Kano Model's analysis method and in-depth interview, and analyzed how the quality of action cam functions affects the user experience by conducting a satisfaction survey by function. The results of the study have shown which functions should be improved first and which functions should be continuously researched and invested. I hope this study will contribute useful information to developing user-centered action cams.
