Abstract: The study applies an integrated framework of environmentally conscious quality function deployment (ECQFD) with weighted decision matrix (WDM) for sustainable development of the tablet device. ECQFD phase I prioritised design metrics were found to be 'product design', 'process improvement' and 'reduced energy consumption' with relative weights of '0.1081', '0.1014' and '0.0916' respectively. In phase II, 'battery' and 'front and back covers' were found to be prioritised components. From phase III option I, 'product design' was found to have more improvement effect and from option II 'process improvement' was found to have the highest improvement effect. From phase IV, option II was found to be the best. Three designs were conceptualised based on the results of ECQFD. Design 1 with a score of 2.63 was identified as the best design using WDM. This study could be beneficial in overcoming the lack of knowledge and realise the potential for successful sustainability implementation through ECQFD.
