Legacy Systems Sustainment
DTSI
believes it is possible to get the best of
both the old and the new technology and take
advantage of technology progress while
leveraging existing assets. As legacy
systems age their associated sustainment
costs will increase dramatically due to
obsolescence, reliability and supportability
problems while at the same time the
performance of the system, as compared to
state of the art or market technology,
decreases.
DTSI’s
early detection of sustainment problems
provides sufficient time to implement an
analysis of viable alternatives and
solutions. The analysis will include support concepts, technology infusion,
re-engineering, commercial technology
and comparisons of life cycle
costs.
DTSI’s approach to legacy system sustainment
is to conduct a
careful
evaluation of the overall IT portfolio to
determine
which core systems should be replaced and
which can be successfully modernized.
Because system replacement carries high risk
in terms of expense and
work disruption, at times it is best to develop a
forward-looking plan that avoids wholesale
replacement. A successful sustainment and
modernization program can keep systems
current with changing business and
technology requirements while saving time,
money and resources.
