Legacy
system evolution - A comparative study of modernisation and replacement
initiation factors
Proceedings of the 9th International Conference on Enterprise
Information Systems (ICEIS 2007).
Decisions regarding information system
evolution strategy become topical as the organisation'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 modernisation and replacement
initiation. System age, obsolete technology and high operation or maintenance
costs were identified as triggers for both modernisation and replacement
projects. The results show that the most prevalent individual reason for
modernisation initiative is business development. Common initiation factors for
replacement projects were end of vendor support and system's inability to
respond to organisation's business needs.
