The intense global market has driven all industries to continuously improve their competitiveness. Among all industrial sectors, the service industry is one of the most decisive industries in increasing the economy and national income. The most important and challenging primary goal of service organizations is to provide high-quality services. The measurement of the main indicators as improving performance is a must to define and measure service quality. One of the main steps in developing this measurement tool is to identify the company's performance and consumer expectations. Service experts agree that service quality results from a comparison between performance and customer expectations. Meeting customer needs can provide a high level of achievement of satisfaction. Therefore, it is very important to understand the difference between customer expectations and service perception. In the service industry, providing high-quality services is the most important thing and needs attention for all types of service providers because service quality can increase customer satisfaction and have an impact on their good name. Therefore, companies and organizations from various service A R T I C L E I N F O A B S T R A C T Article history Received: August 2022 Revised : October 2022 Accepted: October 2022 More specific knowledge about Quality Function Deployment (QFD) has grown rapidly. There are many studies on the application of QFD in various industrial sectors including manufacturing, construction and services. QFD is a tool that can be used to assist companies in improving services by translating consumer desires into the technical characteristics of the company. This study aims to provide a broad understanding and knowledge of the application of QFD in the healthcare industry. The approach used is Systematic Literature Review. This study involves a review study of various papers from well- known databases related to the implementation of QFD in the healthcare industry. This paper provides benefits for researchers and practitioners to add insight and references for studies related to QFD in health services. This is an open access article under the CC–BY-SA license.

One sector of the service industry is health services. Health services are public services that are considered by the whole community and the government because they can coordinate the entire population and awareness of health status. The health care industry must provide high-quality health services because it involves patients. Patients' perceptions of the quality of health services will help medical organizations to increasingly make changes and progress in providing the best services to increase patient satisfaction. Therefore, it is important for the health care industry to continue to improve the quality of services so that the goals of meeting high patient expectations and promoting hospital competitiveness can be achieved. As the demand for improving health services is faced with challenges from various limited resources and intensive competition. Hospitals should be able to prioritize their focus on dimensions that contribute significantly to improving their services. Quality Function Deployment (QFD) is a tool that can be used to assist companies in the production or service process by translating consumer desires into the company's technical characteristics (Narto, 2020). QFD was originally proposed in 1966 as an advanced tool for listening to customer voices for continuous product/service quality planning, quality improvement and decision making. Then in Japan, around 1970 QFD technique has proven to be a powerful tool that can be used to translate customer voice into the technical language (Yamani & Munang, 2019). Cohen (1995) defines QFD as a structured and systematic method for planning and product development that allows the development team to clearly define customer wants and needs. The application of the QFD method in the product design process begins with the formation of a matrix or often referred to as the House Of Quality (HoQ). HoQ displays the voice of the customer (VoC) or the customer's need for a technical response to fulfill it. The HoQ sections/rooms each store specific information for a section of the QFD procedure as shown in Figure 1. Figure 1. HoQ (Source: Cohen 1995) This study aims to provide a literature review on the application of QFD in the health care industry and provide contextual knowledge as a means to improve the application of QFD in health services. RESEARCH METHOD This study presents the best steps to study, explore and analyze the application of QFD in the healthcare industry.

Based on the summary, then grouping into several aspects such as year of publication, country of publication, integration method and publisher. The following is a description of each based on the grouping of papers. Classification of papers This study classify the papers based on the aspects reviewed. The identified papers were traced from publications from 2011 to 2020 (Figure 3). The analysis found that the application of QFD is still relatively new because the development of this tool is reviewed based on the selection of papers in the last 10 years. QFD is considered an innovation in improving the service quality. So this method needs to be developed again. The success of QFD in the healthcare industry has brought significant benefits to the industry sector. Then the QFD method becomes the main target for the service industry, especially health services. Figure 3. Publication by year Based on a thorough identification, as many as 10 papers have used the QFD method as the main method in improving the service quality. This shows that the QFD method is a single method that can provide significant changes when applied. In addition, QFD is also a method for product/service development. QFD itself can provide recommendations for the right model in developing products/services. When applied to an industry or research, QFD is often integrated with various methods of improvement, weighting and decision making to obtain complex results. Based on the 1 3 4 1 6 3 5 4 6 7 2011 2012 2013 2014 2015 2016 2017 2018 2019 2020 SPEKTRUM INDUSTRI Vol. 20 No. 2, October 2022 pp. 69-78 Quality Function Deployment in… (Author et. al.) 74 analysis, the integration method includes the AHP method to analyze or support decision-making. The fuzzy method can model very complex nonlinear functions so that it can build and apply experiences directly. Data Envelopment Analysis (DEA) method as a tool to measure efficiency criteria. Kano's method can lead to the development of broad service differentiation by analyzing customer attributes. The integration of the QFD method with several other methods can be seen in Figure 4. Figure 4. Integration method This study also identifies the distribution of publications by country and publisher. The analysis found that Iran is the largest supplier of publications with 5 papers. Then Elsevier became the most recommended publisher in this literature study. Information about the distribution of papers and where the papers are published can be seen in Figure 5 and Figure 6.

Papers by publisher QFD Implementation Benefits The presence of QFD as an improvement method brings significant advantages to the healthcare industry. This is because QFD can be the basis of activities to translate customer desires. This paper has analyzed the advantages that the healthcare industry gets when implementing QFD. QFD can increase competitiveness through continuous improvement of its quality and productivity. Broadly speaking, the benefits of QFD are as follows: 1. Focus on the customer. 2. Time efficiency. 3. Teamwork-oriented. 4. Orientation to documentation. Figure 7. Benefits of QFD Based on the four benefits of QFD in Figure 7, we can see that specifically the benefits of implementing QFD in the health care industry are increasing product reliability, improving service quality, increasing customer satisfaction, shortening time to market, reducing design costs, improving communication, increasing productivity and increase company profits. This QFD method also has weaknesses, including requiring specific skills when translating quality characteristics, difficulties in filling out the matrix and being a project without continuation. 10 6 3 3 2 2 1 1 1 1 1 1 1 1 1 1 1 1 1 1 Elsevier Semantic scholar IOP Publishing Int.

Quality is paramount to all industries. By focusing on improving quality, customers will feel satisfied. This will have an impact on company profits. In future research, it is recommended to focus more on the application of QFD based on TQM. QFD itself consists of three stages. All activities carried out at each stage can be applied like a project, with the planning and preparation stages first. The three stages are (1) Voice of Customer collection stage; (2) the stage of compiling a house of quality (House of Quality); (3) Analysis and implementation stage. Each stage of the implementation of QFD requires special attention to obtain complex and reliable results. CONCLUSION The main focus of QFD as a method or approach used to improve services so the service industry need to implement it, especially health services. QFD can produce output by the tastes and desires of consumers. Since being developed for the first time QFD has developed into a powerful tool to improve service quality that focuses on customer needs. This method requires special attention at each stage. Through HoQ the implementation of QFD becomes more structured and valuable so that the expected goals will be achieved. Future research is suggested to apply QFD with the TQM foundation.
