VALIDATION OF THE ECO-TRANSFORMITY METHOD
This paper presents validation of a method for qualitative environmental evaluation of product concepts. The basis of the Eco-transformity method are five environmental criteria. Criteria outcomes are collected in a decision matrix and the rank-sum rule is used. To demonstrate that the method supports evaluation and comparison of concepts which are preferably original and innovative, a suitable set of example concepts is established. Validation framework is adapted from the Validation Square, a method for establishing theoretical and empirical effectiveness and efficiency of design methods.
