    The process of product design as an early stage of new product development provides systematic approaches that can lead to the success of a company’s competitive strategy in the current turbulent market. By launching an efficient product design procedure can result in the reduction of engineering modifications, cost and production time. One-of-a-Kind Product (OKP) is known as a particular manufacturing system of new product design and development with emphasis on the special order concept. Quality Function Deployment (QFD) is a comprehensive design framework with cross-functional team members that leads to the development of new or improved products. QFD starts with the House of Quality (HOQ) as an organizing matrix to identify the customers’ requirements (CRs) and translate them into the technical attributes (TAs) of the product and followed by determining the target values for the sets of technical attributes. An evaluation approach to determine the relative importance of CRs and TAs should be considered. In previous researches, the traditional methods such as simple scoring method and application of operational research techniques such as Analytic Hierarchy Process (AHP) were reported to weigh the requirements and attributes. Despite the obvious inner-relationships among the elements, considering the HOQ as a hierarchical system may be inefficient. In addition, the contradictory effects of a TA on two or more CRs, is the problem that has been neglected. Here, a mathematical model was developed for calculating the TAs target values. A case study (dry gas filter, Namdaran Petro-Gas Industries (NPI™)) is presented to exhibit and verify the procedure of OKP product design. Initially, the framework was developed by integrating QFD-operational research (Analytic Network Process (ANP)) as a systematic method for improvement of dry gas filter design. Interview and study of documents were used to identify the CRs. A robust evaluation on customers’ priority and attributes’ importance with respect to inner-relationships among criteria/sub-criteria was performed. Furthermore, the effects of TAs on CRs with regard to their direction (positive/negative) were considered as the fundamental for developing a Multi-Objective Decision Model (MODM) to be used for determining the TAs target values. For this purpose, the fuzzy conversion scaling technique followed by formulating the partial satisfaction separately was applied. Modified TOPSIS was used to select the basic design among the available designs for further modification. Later, the process continues with the second phase, translating the TAs into the key parts. The available options (retailers) to supply the key parts were identified. As the normal procedure of QFD the relative importance’s of key parts and the options were determined. Finally, a zero-one goal programming was presented to select the optimum options for each key part subject to the budget constraint. Overall, the developed QFD-ANP framework provides a systematic approach that has the potential to be used for designing OKP product

    Manufacturing firms are confronted with the challenge to respond to uniqueness of customer demands, uncertain market environment and performance improvement. This study therefore, aimed to provide an integrated strategic model to manufacturing firms to overcome these challenges. The framework was comprised of sourcing strategy, competitive strategy, strategic flexibility, strategic capability and sourcing relationship quality to enhance the firm 's performance. To achieve this, a quantitative research approach was used to collect primary data and Structural Equation Modeling (SEM) was used to analyze the hypothesized effects. Data were collected from manufacturing firm situated in Bangladesh. This study found positive direct effect of exogenous variable; cost-leadership strategy, related product diversification, manufacturing capability and purchasing capability on firm performance and sourcing strategy. Differentiation strategy and unrelated product diversification have not direct effect on manufacturing firm's performance. In addition, sourcing strategy effect on firm performance was positive. Significant positive mediating effect of sourcing strategy was reported in between exogenous variables and firm performance. Moderating effect of sourcing relationship quality was found significant. Sourcing relationship quality therefore, strengthen the relationship of sourcing strategy and firm performance. Empirical evidence of proposed integrated framework was established, and this will help manufacturing firms to improve performance. Manufacturing firms can consider the strategic fit of the study variables and outcome which might help for appropriate decision making and remain competitive. This study also shed light on strategic management literature by approaching moderated mediation model
