Also, it has become extremely challenging in verifying the variables of a product that could lead towards sustainable and successful products in the market. The development of a new product is not only to cater to the users’ satisfactions, but additionally, it should attract more users. In this paper, the Sustainable Product Design Method (SPDM) is introduced as a process to identify and verify the variables of the users’ emotional responses and perceived product quality, and element of sustainability in the early stage of the design process. The SPDM is a design guideline attempt to establish the sustainable product requirements (SPR) towards the sustainable and successful products. To prove the practicability of this method, one of the successful products was chosen as a case study. It has been found that the method built is valuable in facilitating the product designers in the early stage of product design and development process. The validation signified from this process is not only contributed towards product sustainability but also increase on its success in the market.
