Modern approaches for information systems development and maintenance define these processes as standalone ones that causes difficulties in situations where aforesaid approaches are used for large-scale information systems development. Legacy systems and developed from-scratch components integration frequently involves change management and maintenance process. Existing situation requires novel development and maintenance process be developed and actually refers to development and maintenance integration.
This paper introduces Generalized Development and Maintenance Process for information systems based on top of IBM RUP, ITIL, ITSM and State Standards 12207, 15288 intended to be used in large-scale information systems developing and maintaining.
The result of the research defines normative-methodological basis that conforms up-to-date claims and integrates development and maintenance processes.
The result of the research was used in projects of large-scale systems for several banking enterprises.
