ABSTRACT
CASE STUDIES
The paper contributes to the existing Design thinking process by integrating the concept of “Design Matrix” into it. Design matrix focuses more on the measurement of innovation. The positive effects of introducing design matrix are validated through the final prototypes of the three design solutions. The first one involves users who are making different envelopes of various sizes. The second case study involves making of paper bags of standard size. The third case study involves the same set of users making office files. The paper attempts to validate the applicability of Design Matrix to three product case studies. At first glance the problems chosen are very simple but when seen from User’s point of view and by using a matrix – innovation is attempted to be measured. The authors contend that Innovation need not necessarily mean complex thinking or solving complex problems. The paper concludes with proposing future application of processes Design Matrix for complex products.

CONCLUSION • Conceptualization of design based on creative ideas and selection of ideas is very important in the product design phase. • Currently absence of well-defined techniques for selecting product concepts based on innovation criteria has lead us propose a Design matrix based metrics with which we can assess the ‘innovation prospect’. •

Design Matrix approach is adopted in the quest to measure incremental innovation as the product’s design unfolds and evolves into a prototype.
• Future development of the matrix for a complex product is proposed. • Such a matrix is expected to have many sub matrices with complex interrelationships between them. • Individual matrices for materials, processes, usability etc. of the product have the potential in enhancing innovation through design thinking.
