The sustenance engineering of business critical legacy information
systems places huge demand on IT department resources. Legacy systems
are uniquely complex as these systems frequently lack basic documentation
and other in-house maintenance resources. With rapid changes in
technology and business, the availability of application maintenance
resources is very limited but the demand for these resources is
Most legacy systems are based on the traditional system development
model that separates the various programs from data structures (Copybook).
This separation of programs/data creates a intricate relationships,
which places significant challenge in application maintenance and
enhancements. It is essential to fully understand the relationship
between all the source objects of the application to accurately
identify source of a program bug.
These complex relationships are also a critical factor while introducing
any changes to the legacy systems. These changes immediately impact
on other components of the application objects.
Hence the challenge is to improve sustenance engineering productivity
at a reasonable cost to meet the growing need for maintenance, enhancements
and integration while ensuring legacy asset investment protection.
