Product design is one of the most important stages in the new product development
process influencing global sustainability. However, the early design strategy offers the
highest impact on sustainability, the need for using sustainable proactive approach in
early design decisions could be the effective tool to achieve sustainability of new
products. This paper presents a necessity of considering the sustainability aspects in
pre-specification stages of new product design process, and introduces a modified
methodology for establishing a single Index termed as New Product Sustainability
Index (NPSI) which enables the designers to carry out a quick analysis of the
alternatives of new product designs and make choices based on various criteria. The
index aggregates (TBL) and R & D aspects of different types of quantitative and
qualitative indicators and information objects from a product manufacturing point of
view, into one single index. The sustainability matrix, aspects and criteria used in
evaluating of (NPSI), is constructed in table form.
