   Sammanfattning : Organisations play a crucial role as actors that shape material action and societal discourse; therefore, it is important to understand the ways in which they gain legitimacy and how they shape society. The power of accounting representations to construct the accounting object – the organisation – is therefore a key concern in the accounting literature. LÄS MER

7. 5. Adopting Information Systems Perspectives from Small Organizations

   Författare :Özgün Imre; Alf Westelius; Carl-Johan Petri; Nils-Göran Olve; Malin Gawell; Linköpings universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; information system adoption; small organizations; discourse; negotiation; stakeholder theory; social worlds; Economic Information Systems; Ekonomiska informationssystem;

   Sammanfattning : Why do organizations adopt information systems? Is it just because of financial reasons, of concerns for efficiency? Or is it due to external pressures, such as competitor pressure, that an organization adopts an information system?And, how does the adoption take place? Is it a linear process, or is the process one of  conflicts? Does a specific person govern this process, or do we have multiple parties involved? What happens if these conflicts occur among those involved? How does the organization move on and achieve a successful information system adoption?By investigating two organizations, one international academic journal and one South American manufacturing company, this thesis aims to investigate the whys and hows of information system adoption, and aims to contribute to the discourse on information system adoptions in small organizations – an often underrepresented segment in information system adoption literature.By adopting different theoretical lenses throughout the five research papers included, this body of work suggests that even when seemingly simple, information system adoptions can become rather complex.
