Exigen Services Launches Legacy System Rejuvenation Service to Extend Existing IT Application Investments

Exigen® Services, the leading next generation application outsourcing provider, today launched the Legacy System Rejuvenation Service designed to extend legacy IT systems and protect existing investments. The offering provides customers a cost-effective option to replacing entire legacy applications by streamlining and strengthening existing code, and provide a framework for state-of-the-art quality assurance and testing procedures.

Each Legacy System Rejuvenation Service project first undergoes a detailed assessment of the costs incurred by the company from stretching their current legacy systems without rejuvenation. Exigen Services then provides a comparative analysis highlighting the cost savings achievable by modernizing the legacy application.

From the assessment to the finished project, Exigen Services' Legacy System Rejuvenation Service targets specific dangers commonly resulting from relying on outdated systems. Each project consists of the following:

• Application code evaluation: a top-down examination of the legacy application to analyze weaknesses and evaluate what is needed in the most cost-efficient manner. Exigen Services looks at how the application is used currently and what the business requires of it.
• Strengthen and reinforce existing code: identifying what pieces of the application can remain intact and which need replacing or updating to support current and future requirements of the application. Exigen Services uses Agile practices to adapt to unanticipated project changes common when reworking fragile legacy code, keeping the project cost and delivery date in line with the original goals.
• Recapture system knowledge loss: mapping lost or forgotten code knowledge while integrating the updated pieces to ensure future interaction with the legacy system is easy and documented.
• Build Agile quality assurance (QA) and testing practices: identify and implement the most effective combination of automated and manual testing procedures based on established best practices. Exigen Services provides training and documentation for the updated application, empowering customers to manage, test, tweak and interact with the system long after the project is over.

The packaged service is offered in three tiers designed to be flexible and meet the market conditions enterprises are currently dealing with. These include: Basic, Intermediate and Comprehensive. Each tier provides successively-advanced processes, ranging from production of automated functional tests in the tool of the client's choice, through to more complex rejuvenation processes like automated unit testing, coding metrics, and production of automated build and deployment scripts for advanced architectures such as SOA. Each tier can be executed independently or in subsequent stages.

"Dwindling IT resources are forcing many companies to postpone the upgrade of core IT systems and maintenance processes, which in turn is resulting in a higher total cost of ownership (TCO) for the enterprise," said Alex Adamopoulos, executive vice president, Exigen Services. "Our experience in industries like financial services, where the pace of market change is seemingly relentless, has taught us that putting processes in place to use change-ready development methods like Agile for legacy transformation is one of the best ways for a business to realize a return on their IT investments more quickly. This service offering is designed to take that expertise and make the act of legacy transformation more accessible for companies so they are better equipped for the future."

Exigen Services combines leading industry expertise in project management with innovative development methodologies and unique engagement terms to create and deliver applications that solve some of the most complex technology-driven business challenges. Exigen Services' integrated development approach to outsourcing reduces project and delivery risks and improves alignment with clients' goals to meet changing business requirements.
