Abstract: Continuous changing technology and customer requirements are challenging companies to be competitive and ahead of business. QFD was identified as a tool that supports companies in identifying customer requirements and converting them to design or product requirements, yet there are drawbacks in the model which makes it sophisticated and undesirable for certain business environments. The objective of the current research is to revise the traditional QFD by addressing its drawbacks and enable stakeholder requirement identification, prioritization, technical requirement identification and supplier selection through a reliable decision-making process, where the end goal is to encourage workplace learning by allowing the company employs to indulge in the revised QFD process and satisfy the stakeholder requirements by providing the best product, service or solution. The roadmap to achieving this target is proposed through an extended methodology that integrates the revised QFD, AHP and focus group discussion. AHP was identified as an ideal technique that can support requirement prioritization decision-making by minimizing the subjectivity of individual decision-making. This systematic process is conducted in 4 main steps, which are focus group discussion, AHP prioritization, phase 1 QFD for technical/functional requirements identification and phase 2 QFD for supplier selection. This research study has utilized an access control case illustration to validate the proposed framework stepwise. The findings were able to highlight the implications of the revised QFD and the differences between the traditional and revised QFD. Furthermore, future works have been encouraged to improve the methodology, benefits and further development of modernized QFD.
