This paper examines the external influences on ERP project abandonment. The recent literature supposes that the adoption of ICT can be motivated by external institutional pressures, in a process called isomorphism. To gain legitimacy, some firms accept mimetic, coercive, and normative pressures arising from its organizational field to adopt some structures and technologies. Same process is expected to occur in ICT abandonment situations. To investigate this proposal, a single case study about a ERP abandonment process was performed. The results show that abandonment field movement was followed by the organization in focus. This confirms that mimetic pressures have significant influence on project abandonment. Finally, contributions and implications for research and practice are discussed.
