Findings from DeMarco/Yourdon indicate a very unbalanced ratio of maintenance cost versus initial development to be 80 to 20. Simple calculations show that 50% higher development productivity of any new technology, if any, would just yield 0.5 x 20% = 10% savings. If, however, system maintenance can be improved by 50%, savings will be 0.5 x 80% = 40%!
How can such massive savings be achieved? The only answer is automation of the maintenance work itself. This allows getting rid of all routine work and lengthy searches through piles of code and concentrating on the real issues of business rules to change and/or add. Routine work and housekeeping type of activities are over 50% (Strauss, Boehm) of a programmer’s daily work. It is all about transparency, accessibility and ability to search. This functionality is available in the ERP like functionality of G4/Repository, G4/Analyzer and G4/EAM, a fully automated meta-information system used to understand, change and control legacy application systems.
Cornerstone Technology guarantees the savings as agreed in the SLA contract, on condition that the G4-tools are used in the way they are designed for.
Other major savings can be achieved through modernization to open systems and SOA architectures.
ROI of less than 2 years are found getting rid of outdated HW/SW, hierarchical/network databases and outdated programming languages.
Critical Success Factors
Cost savings of IT services. Decrease of TCO over 25%. Application analysis based on meta-information rather than plain code, ERP supported analysis to enhance effectiveness of human expertise. Specific SME related ERP functionality, BRP supported through advanced ERP functionality, SOA re-architecturing based on automated analysis of legacy code, UML modeling automatically generated from legacy code meta-data, fully automated modernization and re-platforming of outdated technology.
Reduce, reuse ad recycle of strategic application systems.
