Application of the Kano Model in the Design and Development of a Breastmilk Cooler Bag

Breastmilk cooler bags are essential for mothers who need to store milk for later use. These bags are designed to keep milk sterile and safe, ensuring it remains uncontaminated and retains its nutritional value. They are flexible and can be neatly stacked in the freezer, optimizing storage space and enabling long-term milk preservation. However, despite their benefits and convenience, several issues arise, including concerns about their properties and cost. This study aimed to identify factors influencing purchasing decisions regarding breastmilk cooler bags. Kano’s model was applied to product development among mothers to achieve this. A total of 33 nursing mothers participated in the study. The model was employed to design a questionnaire exploring consumer satisfaction with various product features. Features that yielded high satisfaction were incorporated into the product design. The analysis using the Kano model indicated that breastmilk cooler bag products effectively met consumer needs for portability, temperature maintenance, packing size, and temperature status indication. This research provides insights into consumer preferences, guiding the development of more effective breastmilk cooler bag products. Limitation and future research are also discussed.
