【正文】 analyzing the voice of the customer, to develop products with higher quality to meet or surpass customer’s needs. Thus, the primary functions of QFD are product development, quality management, and customer needs analysis. Quality management and product development are achieved in QFD through customer needs analysis that, in fact, is always the very first step of a QFD process and is thus an important functional field of QFD [13].. QFD Implementation during the Design ProcessQFD is not a design technique. It is a method from design process to satisfy the customer. It is to guide the design process and to transform customer requirements into design objectives. It is applied to evaluate design solutions or outputs from the creative process of design.. QFD implementations after the design processQFD is a proactive ‘‘customerdriven planning process’’ so that problems could be found and solved at the very beginning of the product development and fewer people have to deal with the problems at the later stages [14].3. Inference Mechanism. Research ToolsQFD offers a rationalized approach to customer satisfactions and seems plex and mathematical with too many data. For some landscape design, it’s not easy to define the average customer, and also customers may not know all possibilities. In the first part of present study, the design team prepared the engineering characteristics that would enable a set of predefined customer needs regarding the fort and improving product performance. Next, the design team used the House of Quality to establish the mutual relations between the customer needs and the engineering characteristics.. Research Question and Research MethodHow a customeroriented approach toward landscape design may be established? Qualitative Research Method is adopted in this paper which being supported by depth interview technique with questionnaire[15].4. Case Study: QFD application in A CustomerOriented Approach Toward Landscape Design. Police ParkThe case study covers a QFD exercise carried out by research team of landscape architecture students of Tarbiat Modares University in the case of Iran, Tehran, Police Park. Police Park is located in the region called the Garden of Majid Abad in the North East area of Tehran and total area is about 42 hectares. Since its pletion in 2003, it has bee the most popular park in the city. This park split to northern and southern section by Street. We will remember to North MajidAbad Park and South MajidAbad Park in this paper. The purpose of this research is employing qualitative techniques to develop performance quality in neighborhood parks design. In this regard, North MajidAbad Park has been selected as samples and South MajidAbad Park as rival Park in puting and data collection in the field is considered, Figure 2.Fig. 2. North MajidAbad Park and South MajidAbad Park. Constructing the HOQ MatrixA difficult and demanding part of the systems engineering process is definition of the problem and identification of the needs to the system. QFD is related to systems engineering in terms of facilitating specification of stakeholders’ wants and needs to the system at each stage from research and product development to engineering and manufacturing, to marketing and distribution. QFD is a method that structures system planning and development, and enables the development team to assess the proposed system systematically in terms of how it meets the needs and requirements [16].? As stated before, the first step in the application is to identify the expectations of park users. To achieve this purpose, Several methods can be used to establish customers39。1. INTRODUCTIONThe urban outdoor spaces have exceptional environmental importance with regard to their contribution to the reduction of various types of pollution and to the improvement of microclimatic conditions. Furthermore, urban open spaces make positive contributions to human health and well being and they lead to an important contribution to human thermal fort in exterior spaces [1]. Beside aesthetic, psychological and health benefits, natural fe
