Abstract

Dalam pengembangan produk, kepuasan pelanggan direpresentasikan melalui hasil kategorisasi atribut produk dalam proses penerjemahan kebutuhan pelanggan, sedangkan pendekatan yang ada masih terbatas dalam mempertimbangkan tingkat kepentingan masing-masing kategori atribut. Penelitian ini memperkenalkan pendekatan terintegrasi QFD-Refined Kano Model-DFMA. Pendekatan terintegrasi ini dikembangkan untuk mengatasi keterbatasan integrasi QFD-Kano dan memanfaatkan Refined Kano Model melalui penggantian kategori atribut produk berdasarkan Model Kano. Penggantian ini menawarkan prioritas pemenuhan atribut produk yang lebih terarah, sehingga pemenuhan atribut dengan tingkat kepentingan tinggi (high impact) lebih diprioritaskan dibandingkan dengan atribut dengan tingkat kepentingan rendah (low impact). Penerapan pada studi kasus pengembangan desain alat traksi (prototype v2) ditunjukkan melalui perincian kategori atribut desain yang ergonomis dari One-dimensional (QFD-Kano) menjadi terkategori Low Value-Added (QFD-Refined Kano Model), sehingga pemenuhannya dapat diprioritaskan setelah pemenuhan atribut yang terkategori High Value-Added. Di sisi lain, hasil penerjemahan kebutuhan pelanggan belum sepenuhnya dipertimbangkan sebagai input dalam redesain produk dengan DFMA. Hasil redesain produk selalu diasumsikan dapat meningkatkan kepuasan pelanggan, sehingga keberhasilannya perlu ditelaah lebih lanjut, yang melandasi keterlibatannya dalam pendekatan terintegrasi ini. Temuan pada studi kasus menunjukkan atribut kemudahan perakitan terkategori High Value-Added, sejalan dengan asumsi peningkatan kepuasan pelanggan, yang direalisasikan melalui penerapan DFA Guidelines dan redesain prototype v1. Namun, temuan ini bergantung pada keberadaan dan tingkat kepentingan atribut, karena asumsi tersebut tidak selalu berlaku apabila atribut tersebut memiliki low impact. Dengan demikian, pendekatan terintegrasi ini berkontribusi dalam mencapai kepuasan pelanggan serta meminimalkan ketidaktepatan dalam pengembangan produk.

In product development, customer satisfaction is represented through the product attribute categorization during the customer needs translation, while existing approaches remain limited in considering the importance level of each attribute category. This study proposes an integrated QFD-Refined Kano Model-DFMA approach to address the limitations of QFD-Kano and to utilize the Refined Kano Model by replacing the product attribute categories based on the Kano Model. This replacement enables a more structured product attribute fulfillment prioritization, in which an attribute with higher impact on customer satisfaction is prioritized over lower impact attribute. The application in a case study on the design development of a traction device prototype v2 shows that an ergonomic design attribute initially categorized as One-dimensional (QFD-Kano) is recategorized as Low Value-Added (QFD-Refined Kano Model). Furthermore, the results of customer needs translation are often not fully incorporated as inputs in product redesign using DFMA, where the outputs are commonly assumed to increase customer satisfaction, therefore their effectiveness requires further examination, which underlies the incorporation in the integrated approach. The case study findings demonstrate that the ease of assembly attribute is categorized as High Value-Added, aligned with the customer satisfaction assumption, which is realized through the implementation of DFA Guidelines and the redesign of prototype v1. However, this finding depends on the existence and importance level of the product attribute, as product redesign does not always increase customer satisfaction when the attribute has low impact. Thus, the integrated approach contributes to fulfilling customer satisfaction and reducing misalignment in product development.
