Management continuously strives for aligning IT-functionality with fast business changes.
Apart from preventive and adaptive maintenance, Cornerstone supports all 4 options available in the marketplace to keep IT applications ready-to-market. With our G4-functionality, our clients regain effectiveness and efficiency of IT services for proper support of their primary business processes.
Choices open to CEO’s and CIO’s:
a. Rebuild applications according to new business requirements.
b. Implement standard SW-package(s).
c. Outsourcing of deployment and functional maintenance.
d. Modernization of existing legacy application.
Expressed in time and cost the 4 choices show following ratios for a, b, c and d:
Rebuild : Standard SW : Outsourcing : Modernization
Time to get full potential available (years)
4 : 3 : 2 : 1
Cost to get application fully operational: (US$ or €)
10 : 8 : 6 : 1
Cumulative Maintenance/Operational cost: (US$ or €)
3 : 2 : 6 : 1
It is therefore quite obvious to opt for modernization of existing legacy systems. After modernization to SOA or Web-enabled architectures, any system backlog will vanish fast. In order to ensure cost-effectiveness, future maintenance issues should be looked after seriously. Based on G4/Repository, the Cornerstone ERP functionality of G4/Analyzer and G4/EAM, gives SLA-guaranteed cost-savings on the enduring maintenance tasks.
