Questionnaires are effective tools which are commonly used for collecting survey data regarding the actual customer’s needs. Such information is required to develop the customer’s needs quality function deployment (CN-QFD) for creating a new product, namely; a sustainable one-handed lipstick packaging. On-line questionnaire/satisfaction surveys are indispensable to obtain accurate results concerning the customer’s needs. Such surveys use a combination of Telrad’s questionnaire procedure to include or exclude the questionnaire in accordance with the mission requirements and the Hybrid QFD Framework to develop a new product. A detailed analysis of the satisfaction survey results reveals the actual customers’ needs which can be further incorporated into the engineering characteristics. After excluding a number of the questionnaires, the remaining ones can be further modified and become the critical parts to construct the final QFD to form the House of Quality (HoQ). In this study, several designed alternatives were considered and the best resolution alternative for the sustainable one-handed lipstick packaging was selected and prototyped accordingly. The round-shape casing encourages keeping the lipstick in the palm of the hand, thus enabling the easy use of the slide-up and -down mechanism. Moreover, the twisting and pulling off of the plastic ring are designed to reduce waste. The cap lid flips up conveniently using only one-hand, which provides a better opportunity to be used suitably and effectively at all times. Finally, the lipstick casing can be reused and the severed ring at the sleeve can also be twirled and removed conveniently which minimizes the waste of lipstick content.
