#### Framework Evaluation Models  
Framework evaluation models are used to analyze framework quality, effectiveness, and usefulness. There are various types available, each with their own set of benefits and drawbacks. When choosing a model, it is essential to consider both the specific purpose of the evaluation and the elements of the framework under discussion. Taken together, these points represent the internal and external validity of a measured instrument. This section examines the differences between selected evaluation models for theoretical frameworks depending on the purpose and context. While there are several such models, the technology adoption/acceptance model (TAM), theory of planned behavior (TPB), task-technology fit (TTF), end-user computing satisfaction (EUCS), and unified theory of acceptance and use of technology (UTAUT) are commonly used in information systems literature [25; 26; 27; 28]. The technology acceptance model (TAM) describes how users interact with technology and institutional institutions. It is based on two significant factors: perceived ease of use and perceived usefulness. Perceived usefulness measures how much an individual believes that adopting a given system will improve their work performance, whereas perceived ease of use measures how easy it is to use the system. These characteristics have a significant impact on an individual's attitude toward system usage, which influences their intentions and actual adoption. It proposes a direct relationship between perceived usefulness and behavioral intention, emphasizing the importance of an individual's attitude in shaping their decision to accept and use a system. In addition, it has been integrated with other models, including the task-technology Fit (TTF) model, to provide a more comprehensive explanation of variations in IT utilization [29]. End-user computing happiness (EUCS) is a model for measuring user happiness with technology, with a particular emphasis on the computing and usage aspects that make up an information system. EUCS includes an overall effective evaluation of the system by end users and employs a 12-item assessment to evaluate criteria such as content, correctness, format, simplicity of use, and timeliness [29]. It is a reliable predictor of user happiness, especially in integrated systems, and provides valuable insights into the identification of problematic issues in system implementation. It is crucial to highlight that EUCS may involve longitudinal studies to capture developing attitudes over time, and there may be issues with the precision and comparability of overall user satisfaction scores. According to the model, five aspects influence user satisfaction: perceived usefulness, perceived ease of use, information quality, system quality, and service quality. EUCS, as an adaptable tool, significantly contributes to understanding and improving user satisfaction across multiple technical contexts and may be used to evaluate many sorts of technology [29]. The unified theory of acceptance and use of technology (UTAUT) is a comprehensive model that combines and extends various technology acceptance theories, aiming to understand and predict technology adoption and usage. To gain insight into users' intentions and activities, it looks into variables such as performance expectations, convenience of use, social impact, and enabling conditions. UTAUT has several applications in information systems and technology, providing insights into the factors that influence technology adoption. Despite its widespread acceptance and use, several experts have raised concerns about its practicality and theoretical assumptions [30]. The theory of planned behavior (TPB) is a psychological theory designed to elucidate and foresee human conduct. It states that people's intentions--which are further influenced by their attitudes, subjective standards, and sense of behavioral control--determine their behaviors.
