Abstract: Decisions regarding information system evolution strategy become topical as the organization’s information systems age and start to approach the end of their life cycle. An interview study was conducted in order to compare factors influencing modernization and replacement initiation. System age, obsolete technology and high operation or maintenance costs were identified as triggers for both modernization and replacement projects. The results show that the most prevalent individual reason for modernization initiative is business development. Common initiation factors for replacement projects were end of vendor support and system’s inability to respond to organization’s business needs.
