The impact of information technology extends beyond organizational levels, bringing about significant changes in business structures and methods, including those of telecommunication service providers such as PT. Indosat Ooredoo Hutchison in Indonesia. The digital transformation implemented by PT. Indosat aims to enhance efficiency for its employees through the utilization of the YES app, which provides information on the company's performance in the sales domain. However, regional offices indicate a lack of readiness and optimization in utilizing this technology. This study endeavors to empirically assess the reception of the YES application at PT. Indosat Ooredoo Hutchison using the Technology Readiness Acceptance Model (TRAM). The study employs Structural Equation Modeling (SEM) to analyze the data collected from questionnaires distributed to 95 PT. Indosat employees residing in Sumatra. The research findings reveal that optimism and innovation do not significantly influence Use Intention. Conversely, inconvenience has a positive and significant impact on Use Intention, while inconvenience has a negative influence on intention to use through the mediation of user convenience. Insecurity positively influences Use Intention, whereas user convenience has a negative impact on Use Intention.
