Major Cloud Solutions Specialist, US

Porting of business rules accumulated over 20 years without impacting production users.

XOR created a customized product for our client to remove dependency on a high cost third party product that had technical limitations. All the business rules that had been written on the 3rd party tool for over 20 years were re-written within a short span of 18 months.

  • XOR client used a third party engine to write business rules on. This engine allows rules to be written in a specific format/language that can be compiled and run using this engine only. This tool was being used to write business rules for 20 years and it had an accumulation of rules for all these years.
  • The tool has a high cost and proprietary nature with limited to no support available. The client was fully dependent on the tool and had to pay the cost as the rules could not be compiled or run without it.
  • 3rd party increased the cost of using the product significantly every year.
  • The client wanted to get a customized tool for their business requirements that gave more flexibility and rules to be written such that there was no dependency.

How We Made It

  • Creating a customised product for a client requires a deep understanding of the existing system. To re-write business rules also required understanding of the specific format of the third party product used by the client.
  • XOR team carefully understood the existing requirements and designed a tool that caters to current and future needs. XOR also carefully ported all the business rules without impacting the existing production environment in a phased manner.
  • This helped clients to reduce the cost which increased the profits. Along with this, business rules are now in a generic format that is much easier to understand and update which will reduce maintenance costs as well.


    • Removal of costly 3rd party app and business dependency.
    • Multifold improvement in application performance. Application performance improved by more than 70% in most cases.
    • New customized engine resolved memory limitations users faced while creating large designs.
    • More scope to introduce new features/functionalities for users which were earlier not possible
