The framework will be used to consolidate the information of sustainability issues involving environmental, social and economic by integrating the design stage and supply chain activities. A list of the current sustainability issues in supply chain, from 2014, will be extracted from five companies namely Apple, Panasonic, Sime Darby, IKEA and Sony. Hence, the current sustainable issue was identified and the proposed framework developed will guide the development of a score metric for sustainable supply chain in the design phase. Keywords: supply chain, design phase, sustainability, score metric. INTRODUCTION The product development process moves very rapidly nowadays and hence new tools and techniques are needed to enhance this process. The tools and techniques were developed in order to meet customer and technical requirements. Through this, the product time to market can be further reduced by not sacrificing the quality of the product. Currently, sustainability becomes the issue that may affect the cost and time needed in product development especially in the operational stage. Sustainability calls for three pillars whuch are profit, planet and people, which is also known as the triple bottom line (TBL). The environmental, social and economics are the TBL issues. Supply chain is one of the process in the development of new product. It involves partners such as supplier, manufacturer, distributor, retailer and customer. In order to develop a new product, the design stage play an important role to make sure it can be considered in any other stages in product lifecycle. As supply chain generate the systematic flow of product lifecycle, it needs some effort in the design stage by introducing a new type of assessment so that it can be use to satisfy the whole process of supply chain to manage to optimise the cost and time needed. Environmental issues are obviously important for human life especially for the future generation. Because of that, engineering activities totally need to work simultaneously with prevention/reduction of negative effect on ecosystem. This effort is the responsibility of everyone involved in product development starting from pre-manufacturing, manufacturing, product in-use and product recovery stages. In this case, the effect on the environment from these activities must be considered and kept in mind. Through the process of supply chain the information flow can be managed in the best way in order to connect the various stages involved in product development. This paper will discuss further about specific factors of sustainability effect on supply chain. Next, the methodology framework of developing the score metric for sustainability supply chain will be proposed. PRODUCT DESIGN AND SUPPLY CHAIN SUSTAINABILITY Product Lifecycle Management (PLM) is the process involving the various types of stages. In this context, the process provides the product flow from stage to stage. Through various stages, the information management is most important part to connect the strategy and operation in order to produce product which satisfy the customer needs. Product design, manufacturing process and supply chain activities must be link in similar direction so that the capabilities and the competencies can be flexible, advance process technologies and collaborative supplier practices (Marsillac AND Roh 2014). In order to achieve that, the alignment product design with supply chain performance must be improved so that it can be responsive (Khan et al. 2012). In design stage, there are many design tools which are not only capable to do the design work but can also be used to define the further stages of product lifecycle including manufacturing, logistic, product in-use and product recovery. Because of that, there are a lot of interest in developing new tools which can help the designer in order to consider/identify some aspect of product chain. The tools developed can be used to reduce the cost of production with the time-to-market can be minimize and the product quality can be remain. Day by day, the request for product in the market increase inline with the increase of users/consumers. This make the industry players compete rigorously with different types of techniques and systems. Industry must adapt in these situation so that the demand by users/consumers can be met. Design stage Design stage can provide a lot of data about the product development. This is because the process in this stage will consider a lot of information which will give an
