Zhrnutie	The Technology Acceptance Model (TAM) is a theoretical model of why people accept or reject information technology, introduced by Fred Davis in 1989. Adapting the Theory of Reasoned Action, it posits that two beliefs—perceived usefulness and perceived ease of use—shape attitudes and behavioural intention toward a system, which in turn drives actual use. The constructs are measured with validated survey scales and the relations are typically estimated as a structural equation model.	Technological Innovation Systems (TIS) analysis studies the emergence, growth, and performance of a specific technology by treating it as a system of actors, networks, and institutions that interact to generate, diffuse, and use that technology. Building on the systems-of-innovation tradition, the influential scheme of Bergek and colleagues combines a structural account of the system's components with a functional analysis of the key processes—or functions—that an innovation system must perform, then compares achieved with desired functionality to diagnose inducement and blocking mechanisms and derive policy.
