Application Re-engineering

Case Study

Application Re-engineering
Client Profile:
A leading national provider of intelligent software and service solutions
that empower legal professionals to more effectively manage dynamic
information, speed workflows and make critical decisions. Its customers
include over 90% of the Fortune 500 companies and top U.S. law firms.
They have more than 1,500 employees in many locations nationwide.
A sophisticated customer information management system is used internally to support the fulfillment of services. This distributed system is used
by both its internal employees as well as the fast network of suppliers.
The custom internal system was last implemented over a decade ago using client server technology that, while state
of the art at the time of implementation, had become outdated with the wide adoption of the internet and needed to
by updated. In addition, many of the specific business rules embedded in the system were not documented completely anywhere outside of the system and therefore needed to be reconstructed and updated to reflect current and
future business goals.
The Digital Group’s engineers designed and implemented a web based application to replace the existing legacy
system. This project involved a full life-cycle development effort from requirements through deployment. Some of
the specific tasks included:
» Cleanup and migration of legacy data to Oracle 9i database.
» Build the new application using .net framework in a three-tier model.
» Utilize the existing client’s framework to develop the application which will help in easier maintenance and less
» Provide rich documentation and user manual for the usage and maintenance of new system.
The team provided by The Digital Group included resource divided across three separate locations
» Offshore ( Pune, India),
» Offsite ( Princeton NJ, US),
» Onsite-Client (New York City, US)
By utilizing resources at all three locations the client was able to achieve the maximum value for each type of
resource employed. The Digital Group managed the coordination of the resources at these remote sites thereby
freeing the client from needed to supervise this complicated process. The Digital Group also provided Quality
Assurance services for the web-application, during QA phase. After 2 years of continuous efforts and hard work
the project went live.



With the implementation of the new system the client was able to see immediate benefit from both the users of the
system as well as the IT operations team. Some of these benefits include:
Improved End User Efficiency
» Web based application more intuitive then previous application
» System performance improved
» SRich and complete user guides and training materials
» Vastly simplified deployment to new partners
Improved IT Efficiency
» Implemented process centric approach to the entire data management function
» Perform validation of source data before loading
» Extensively documented all processes
