APPLIED QUALITY FUNCTION DEPLOYMENT IN RESIDENTIAL CONSTRUCTION PROJECTS
Nouran Ashraf Abdel Halim;
Abstract
Quality function deployment (QFD) is a methodology to transform the voice of the customers to the engineering requirements. QFD is being used in different industries; where it was initiated in manufacturing and was recently introduced in the construction industry. In this research, the first phase of QFD is implemented in residential construction to improve the quality of housing projects. QFD can improve housing quality by identifying the factors affecting the customers’ satisfaction with the product. It mainly focuses on transforming customers’ demands into product requirements. QFD applications in construction occur before the design, during design and after design.
In residential construction projects, many problems are uncovered after construction and may have effects on customers’ satisfaction. By using QFD, companies will be able to identify the customer’s needs, convert them into quality indicators and facilitate competitive benchmarking in a structured way. Then, the organizational infrastructure (availability of databases, utilized environmental scanning tools, etc.) will help the company overcome the current problems in the future, and in planning for the new projects based on the results of the data analysis of the pervious projects and help the company in making decisions for the new projects.
The house of quality (HOQ) is the first phase of QFD and the basic tool for QFD. HOQ translates customer requirements, based on market research and benchmarked data, to engineering targets to be achieved by a new product design. The inputs of the HOQ are the customer requirements and their relative importance based on questionnaires, focus groups and interviews. The outputs of the HOQ are the most important technical requirements to customer requirements and competitive analysis.
The research has three objectives: (1) to explore the benefits and limitations of applying QFD in designing new residential construction projects; (2) to investigate the potential of using QFD to assess the level to which an existing residential project meets customers' demands using QFD; and (3) to study the cost implications of meeting the identified customer demands.
New Heliopolis City is one of the newly developed cities in Egypt. It was under construction since 1995. The city consists of two phases; phase one construction is almost complete and phase two is still in the planning and designing stage. HOQ was applied after design for phase one and during the design for phase two of the city. Applying HOQ will be important for the city to achieve the customers’ satisfaction with the current project and also to improve the future projects.
After applying QFD to the case study, the importance of customer requirements are generated based on the output from HOQ and the effect of those requirements on the apartment price is analyzed. The results are compared with the company’s current perspective and priority to match customer needs.
