Replace EOL Software

Replace EOL Software

Legacy software/hardware platforms that are no longer supported by vendors or have been built on dated technology where finding a qualified personnel is hard or expensive do not meet dynamic enterprise needs and even result in increased IT debt, complexity, and maintenance costs.

Replace COTS Platforms

Replace COTS Platforms

COTS applications in need of an expensive upgrade that will not result in the desired ROI or having reached their limits of business value add on to the infrastructure and maintenance costs and no longer achieve the desired objectives around enterprise scale

Augment Core Legacy Apps

Augment Core Legacy Apps

Although the underlying legacy system is efficient it does not deliver the desired user experience or include the advanced set of capabilities for end-users. By implementing robust APIs and keeping the core app intact, augmentation results in improved UI across touchpoints.
