“…Wierenga and Ophuis (1997), for example, identified adoption intention, adoption, implementation, and post-implementation phases, whereas Cooper and Zmud (1990) identified six stages: initiation, adoption, adaptation, acceptance, routinization, and infusion. However, to date, most empirical studies on transition economies focus on IS adoption (Bernroider, Sudzina, & Pucihar, 2011;Soja, 2011Soja, , 2015Soja & Paliwoda-Pękosz, 2013), while the post-adoption stages of IS remain uncovered. It is nevertheless important to also devote attention to the latter phases.…”
