Due to globalization, market dynamics, and customer interest variations, the manufacturing industry is facing high computational challenges. To overcome these problems, the issue of mass customization (MC) has received substantial attention in the manufacturing industry. The efficiency and effectiveness of mass customization are measured by the capability of producing customized products without sacrificing product quality, cost, delivery time, variety, and volume. It is known that manufacturing strategies are the basic enabling factors for the effectiveness and efficiency of mass customization. However, most studies did not clearly define the impact level of each enabling factor on each of the mass customization capabilities. The main objective of this research was to identify the level of impact of manufacturing strategies on each mass customization capability. A fuzzy Delphi questionnaire designed with a seven-point scale has been applied to obtain expert opinions on the impact level of each enabling factor. The opinions were combined for each enabling factor by considering the importance level of each expert and aggregated by using an algorithm. Finally, the level of impact of each enabling factor on each mass customization capability was clearly identified. The result shows that even if the level of impact varies, all the manufacturing strategies have their own impacts on product cost, variety, quality, volume, and delivery time called mass customization capabilities, which are the basic factors to maximize the effectiveness and efficiency of mass customization.
