Abstract
Conference Title: 2018 IEEE 5th International Conference on Engineering Technologies and Applied Sciences (ICETAS) Conference Start Date: 2018, Nov. 22 Conference End Date: 2018, Nov. 23 Conference Location: Bangkok, Thailand Although Software as a service (SaaS) solutions offers promising outcomes on IT performance and competitive advantage, it is observed that adoption and acceptance of SaaS solutions by the consumers has been lower than expected. In this line, present article proposes an extended model of technology acceptance to understand the decision making process of potential users towards SaaS usage. The theoretical frame proposed in this article integrates important variables from the usability engineering, human computer interaction, and cloud computing domain. These variables are perceived usefulness, perceived ease of use, usability, trust, and facilitating conditions. It is anticipated that the systematic framework of integrated factors developed in this article will be helpful for the SaaS solution providers.
