Toward Understanding PU and PEOU of Technology Acceptance Model

Technology Acceptance Model (TAM) is considered one of the most popular models used in Information System (IS) research. Fred Davis developed this model as part of his doctoral research at MIT in 1986. Since then this model has been widely used in IS research and other disciplines. Two main components of TAM are Perceived Usefulness (PU) and Perceived Ease of Use (PEOU). This model allowed researchers to plug-in external factors to these two components. Researchers have used a variety of external factors to draw relationships between these two internal factors of TAM model. However, most of the research used these TAM-based internal factors without elaborating actually what makes a system or technology useful. This research makes an attempt to understand those two internal factors based on literature review and a comprehensive exploratory study. The author proposes a set of external factors that are technology focused and have practical value. This work is expected to guide future researchers in using this model with proposed external factors that match the definition of PU and PEOU.
