Crosskey Banking Solutions Chooses MKS for Application Lifecycle Management Worldwide.

WATERLOO, Ontario -- MKS Inc. (TSX:MKX) announced today that Crosskey Banking Solutions, a supplier of state-of-the-art banking computer systems for small and medium-sized banks, and a wholly owned subsidiary of the Bank of Aland in Finland, has selected MKS Integrity to enable application lifecycle management (ALM) across the company's distributed and iSeries environments. Crosskey Banking Solutions develops cost-effective banking systems that allow personalised banking service, including modules for front-office, back-office and E-banking.

Crosskey has invested in MKS's ALM solution to improve development efficiency while supporting the creation of custom banking solutions for multiple customers. MKS Integrity will allow Crosskey to transition to task-based change management from its existing file-based version management system, better integrating change requests with the development process, and enabling a more structured software release process. After an evaluation of the market, Crosskey chose MKS for its broad and highly integrated ALM support spanning distributed and iSeries platforms.

"Our business model is based on adaptation and re-labelling of a standardised system core, which allows our customers to efficiently deliver banking services under their own brand. Systems are designed by Crosskey uniquely to fit each customer's brand image and wishes, while sustaining short implementation times and low development costs. MKS's application lifecycle management solution allows us to manage ongoing change to multiple systems in a highly orchestrated, organised and efficient way," says Niklas Ekebom, Specialist, Crosskey Banking Solutions.
