Technological devices and information and communications technology (ICT) have become the new tactic for communication, collaboration, and the exchange of knowledge and innovation between organizations and users. These devices include websites, system and application software, and mobile and portable devices. Nevertheless, it has been noted that these devices, including websites, still lack important functionalities and utilities, i.e. Human Computer Interaction (HCI) and usability. HCI and usability are essential in any device to allow the user to complete his/her task(s) in less time and with high-quality performance. The absence of HCI and usability aspects in technology devices and ICT will lead users to become frustrated and dissatisfied, and their loyalty will be reduced. A new coherent methodology called the New Participative Methodology for Marketing Websites (NPMMW) was developed to prevent this problem. The HCI and usability aspects are combined in the design stage, in the NPMMW, to increase user acceptance of the website, and to reduce users' dissatisfaction. This study employment an online survey (N=210) from an Australian information technology industry that allowed the collection of both quantitative and qualitative data. The study provided theoretically and practical significance contribution; that HCI and usability integration in the NPMMW would enhance users' acceptance, satisfaction, trust, and loyalty, and would minimize users' frustration and aggravation, likewise; the NPMMW methodology will assist designers and users to create an effective website that meet the requirements of users and designers. Finally, an overview of the NPMMW methodology is provided, together with proposals for further research.
