Case Studies
TAX INDUSTRY >>> Legacy System Conversion
The Marmon Group is an international association of autonomous manufacturing and service companies with corporate headquarters in Chicago.
Business Problem
The Marmon Group's Corporate Tax department was relying
on a 15-year-old Oracle system hosted on Unix to manage
the tax compliance process. This mission-critical system
was becoming (with each passing year) less stable, harder
to maintain and backup and increasingly difficult to
support and enhance. In addition, the interface was
slow, complicated and outdated, increasing the difficulty
of training new users.
Solution
Migrate the mission critical tax compliance software to a stable platform, that integrated well with the current tax department environment, while maintaining all existing functionality. Add additional functionality where possible and allow for future growth. In addition maintain the accuracy of decades worth of tax information and keep down time to an absolute minimum.
The Bone Group migrated the Oracle/Unix legacy system to Windows NT using SQL Server 2000 as the back-end database and a Microsoft Access Data Project to generate the forms, reports and menus.
In order to ensure a smooth conversion process the Bone Group documented the existing system's functionality and modeled the database design in Visio to enhance performance. A data conversion tool was created that could be reused throughout testing and implementation, allowing testers to work with the most recent data.
During the development process, The Bone Group worked closely with the tax department to understand which pieces of the system worked well and which could be improved. To ease the review process for the tax department, The Bone Group setup the ability for the tax department to review the system over their existing internet connection. This gave the tax department testers the ability to review the system from their desk, at their own convenience.
