Due to the lack of system quality, the delivery team is afraid to introduce modifications to the system and blocks your ideas.
Each change, even a relatively simple one, takes a long time - weeks or months.
Your IT teams spend more of their time maintaining the codebase, rather than developing new services or features.
Your end users or customers complained that competitors have faster, friendlier systems for them to use.
Most of the system is tested manually, which requires an army of testers, increases costs and delays deployment of changes.
It becomes harder to find talented technology specialists and keep them in a company.
You have tried to modernize your system before, but it ended in failure.
If just one of these points hit home, then it’s a good time to look at a different, evolutionary approach and begin making improvements
right now! – Meet ELSAF framework.
ELSAF, developed by ITSG Global, is a comprehensive framework designed to incrementally upgrade legacy systems towards modern architectures. It is very much a phase-by-phase approach to get the most value out of targeting specific areas of the codebase that need investigation and remediation.
It is the digital adaptation of the
physical Lean Manufacturing
process based on
Incremental changes on architectural level towards modularity and loosely-coupled architectures based on business capabilities.
Iterative, continuous process of increasing system testability and automatability. Test automation treated as first-class citizen of the system.
Incremental, continuous code refactoring resulting in constant improvement of the system along with the delivery of new functionalities.
Automated, always up-to-date documentation that forms the bridge and common dialogue between IT development teams and non-technical business stakeholders, in terms of knowing how the system works.
It’s important to understand your business drivers for modernizing a legacy codebase.
By working with our legacy modernization teams, your business will be able to:
Cut IT spend and software development costs
Improve developer experiences
Adapt quickly to market shifts
Expand to new markets
Focus on growing business over maintaining
Become more competitive
Enhance customer experiences
Moreover, using external experts leads to additional benefits that include:
Increased operational efficiency
Reduced hiring costs
Better employer branding and lower specialist rotation
Repositioning specialists from low-value tasks to essential tasks
Meeting compliance, security and regulation standards
